+
+2016-03-25 0.12.8
+- Major changes (see details below):
+  - Icon cache and lazy icon theme loading to improve performance in tint2 and tint2conf
+  - Extra tint2rc themes are installed to /usr/share/tint2 and available in tint2conf
+  - Tint2conf GUI improvements
+- Config options with changed behavior:
+  - The launcher now also allows launcher_item_app entries without a full path.
+    In this case the .desktop file is searched in the standard application directories (issue #565).
+  - If the panel size is given as a percentage and a non-zero margin is also specified,
+    the size is now computed as a fraction of the available size (i.e. monitor size - margin).
+    Before it was computed as a fraction of the monitor size first, then the margin was subtracted from the value, which
+    was not intuitive (issue #559).
+- Fixes:
+  - Taskbar icons are now resized correctly for certain geometries (issue #560)
+  - Fix get_version.sh so that it returns the correct version when .git is missing
+  - Fix build on powerpc
+  - Temporary files are now created in /tmp
+  - The XDG paths are now used in the icon and application lookup in addition to the hardcoded defaults
+  - Brigtness adjustments no longer distort colors
+  - Fixed race in sorting systray icons by name
+  - Fixed desktop entry parsing (issue #570)
+  - tint2conf:
+    - Applications are now sorted correctly
+    - Avoid duplicate icon themes due to symlinks
+    - Avoid loading desktop files marked as NoDisplay
+- Enhancements:
+  - Launcher icon paths are now cached, which greatly improves loading time for tint2 and tint2conf.
+    The correct icon should be found even if you change the icon theme or install a new theme.
+    If this is not the case, delete the file ~/.cache/tint2/icon.cache, restart tint2 and please file a bug report
+    indicating the application name and the icon theme name.
+  - Fallback icon themes are loaded lazily to speed up tint2 and tint2conf startup
+  - A better Name and GenericName is used in the tint2 and tint2conf .desktop files
+  - tint2conf:
+    - Allows selection of themes from /usr/share
+    - Menu reorganization (thanks @Vladimir-csp for feedback)
+    - Icon themes are now sorted in the displayed list
+    - Updated ru translation (thanks @Vladimir-csp)
+
+2016-01-29 0.12.7
+- Fixes:
+  - Fix crash caused by race when reading inconsistent values for _NET_CURRENT_DESKTOP and _NET_NUMBER_OF_DESKTOPS
+  - Fix regression (all desktop tasks not working)
+  - Fix small memory leak in launcher
+
+2016-01-25 0.12.6
+- Fixes:
+  - Fix crash on 32-bit systems (issue #546)
+  - Fix compilation on Slackware (issue #547)
+  - Terminal color reset code moved to the same line to prevent interference with logging (issue #545)
+- Enhancements:
+  - Executor now sends click coordinates via environment variables (issue #544)
+
+2016-01-24 0.12.5
+- Fixes:
+  - Fix rendering corruption triggered occasionally when the compositor is disabled (regression in 0.12.4)
+
+2016-01-23 0.12.4
+- Enhancements:
+  - Support for NETWM viewports (as used by Compiz or Unity) (issue #94)
+  - The default desktop font (Gtk/FontName from XSettings) is used when a font is not specified in the config file
+  - When no fonts are specified in the config, tint2 picks up the default font of the desktop environment via XSettings
+  - Tint2 is now able to dump a stack trace to stderr and ~/.tint2-crash.log in case of a crash.
+    If the cmake flag ENABLE_BACKTRACE is set, stack traces are dumped on X11 I/O errors.
+    If the cmake flag ENABLE_BACKTRACE_ON_SIGNAL is set, stack traces are dumped also on signals such as SIGSEGV.
+    Both ENABLE_BACKTRACE and ENABLE_BACKTRACE_ON_SIGNAL are disabled by default.
+  - Pixmaps are cached instead of always redrawn between different button states when mouse effects are enabled,
+    to improve performance
+  - Tooltips are no longer very wide
+  - Default config looks nicer
+- New config options:
+  - Executor: new plugin that displays the output of a command in the panel (issue #161)
+  - New taskbar sort order options: least-recently-used (lru), most-recently-used (mru) (issue #532)
+  - Place the primary monitor before all the other monitors (primary_monitor_first, issue #538)
+  - taskbar_always_show_all_desktop_tasks (issue #279)
+- Config options with changed behavior:
+  - Mouse effects are enabled by default
+- Fixes:
+  - Battery changes visibility correctly (issue #531)
+  - Fixed rendering corruption (issue #543)
+  - Reverted the window flags back to the value in 0.11 to make sure the window manager detects that tint2 is a panel
+    (affected kwin, bspwm; fixes issue #537, breaks issue #455)
+  - Fixed a rare crash caused by the system tray code
+  - The system tray now reorders icons correctly when the icon name changes and the sorting order is configured as
+    ascending or descending (affected GTK icons, which sometimes set their name late after creating the icon)
+  - Tint2conf no longer copies sample themes to ~/.config
+- New optional dependencies:
+  - libexecinfo on the *BSDs (only if the cmake flag ENABLE_BACKTRACE is set)

+- Enhancements:
+  - Battery: Multiple batteries are now supported under Linux (issue #139;
+    thanks to Sebastian Reichel)
+  - Battery: The time left for charging/discharging the battery is now estimated
+    when the system is not able to read current data from sensors (issue #522;
+    thanks to Sebastian Reichel)
+  - Battery: Reacts to plug/unplug events (thanks to Sebastian Reichel)
+  - tint2conf: Backgrounds now have a text label showing which panel component
+    uses them, to make them easier to identify; the label is saved as a comment
+    in the config file (issue #521)
+- New config options:
+  - Mouse over effects (mouse_effects, background_color_hover, border_color_hover)
+  - Launcher icon background (launcher_icon_background_id)
+  - Enable/disable battery tooltips (battery_tooltip_enabled)
+- Fixes:
+  - Updated French translation
+  - The correct icon is now used in tint2.desktop (issue #523)
+  - The font setting for the desktop name is no longer lost on tint2 restart

 P.S. GitLab is now the official location of the tint2 project, migrated from Google Code, which is shutting down. In case you are wondering why not GitHub, BitBucket etc., we chose GitLab because it is open source, it is mature and works well, looks cool and has a very nice team.

+You may also use instead the graphical interface <code>tint2conf</code>.</p><p>The first time you run tint2, it will create the config file in <code>$HOME/.config/tint2/tint2rc</code> (This applies if you have done a clean install. Running tint2 in the source directory without doing &#39;make install&#39; will not create the config file.)</p><p>You can also specify another file on the command line with the -c option, e.g.: <code>tint2 -c $HOME/tint2.conf</code>. This can be used to run multiple instances of tint2 that use different settings.</p><p>If you change the config file while tint2 is running, the command <code>killall -SIGUSR1 tint2</code> will force tint2 to reload it.</p><p>All the configuration options supported in the config file are listed below.

+<ul>
+<li><p><code>rounded = number_of_pixels</code> : the corner radius</p></li>
+<li><p><code>border_width = integer</code> : the border width in pixels</p></li>
+<li><p><code>border_sides = LRTB</code> : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. <em>(since 0.12.12)</em></p></li>
+<li><p><code>background_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>

+<p>You can define as many backgrounds as you want. For example, the following config defines two backgrounds:</p><pre class="highlight plaintext"><code>rounded = 1

+background_color = #f6b655 90
+border_color = #cccccc 40
+</code></pre>
+<p>tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:</p><pre class="highlight plaintext"><code>panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0

+.SS Introduction
 .PP
-This manual page was written by Daniel Moerner <dmoerner@gmail.com>,
-for the Debian project (but may be used by others).  It was adopted from the
-tint2 docs.
+These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface \fB\fCtint2conf\fR\&.
+.PP
+The first time you run tint2, it will create the config file in \fB\fC$HOME/.config/tint2/tint2rc\fR (This applies if you have done a clean install. Running tint2 in the source directory without doing 'make install' will not create the config file.)
+.PP
+You can also specify another file on the command line with the \-c option, e.g.: \fB\fCtint2 \-c $HOME/tint2.conf\fR\&. This can be used to run multiple instances of tint2 that use different settings.
+.PP
+If you change the config file while tint2 is running, the command \fB\fCkillall \-SIGUSR1 tint2\fR will force tint2 to reload it.
+.PP
+All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.
+.SS Backgrounds and borders
+.PP
+The tint2 config file starts with the options defining background elements with borders:
+.RS
+.IP \(bu 2
+\fB\fCrounded = number_of_pixels\fR : the corner radius
+.IP \(bu 2
+\fB\fCborder_width = integer\fR : the border width in pixels
+.IP \(bu 2
+\fB\fCborder_sides = LRTB\fR : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. \fI(since 0.12.12)\fP
+.IP \(bu 2
+\fB\fCbackground_color = color opacity\fR
+.RS
+.IP \(bu 2
+\fB\fCcolor\fR is specified in hex RGB, e.g. #ff0000 is red
+.IP \(bu 2
+\fB\fCopacity\fR varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).

+You can define as many backgrounds as you want. For example, the following config defines two backgrounds:
+.PP
+.RS
+.nf
+rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+.fi
+.RE
+.PP
+tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:
+.PP
+.RS
+.nf
+panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+.fi
+.RE
+.PP
+Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.
+.SS Gradients
+.PP
+(Available since 0.13.0)
+.PP
+Backgrounds also allow specifying gradient layers
+that are drawn on top of the solid color background.
+.PP
+First the user must define one or more gradients in the config file,
+each starting with \fB\fCgradient = TYPE\fR\&. These must be added before backgrounds.
+.PP
+Then gradients can be added by index to backgrounds,
+using the \fB\fCgradient_id = INDEX\fR, \fB\fCgradient_id_hover = INDEX\fR and
+\fB\fCgradient_id_pressed = INDEX\fR, where \fB\fCINDEX\fR is
+the gradient index, starting from 1.
+.SS Gradient types
+.PP
+Gradients vary the color between fixed control points:
+* vertical gradients: top\-to\-bottom;
+* horizontal gradients: left\-to\-right;
+* radial gradients: center\-to\-corners.
+.PP
+The user must specify the start and end colors, and can optionally add extra color stops in between
+using the \fB\fCcolor_stop\fR option, as explained below.
+.SS Vertical gradient, with color varying from the top edge to the bottom edge, two colors
+.PP
+.RS
+.nf
+gradient = vertical
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+.fi
+.RE
+.SS Horizontal gradient, with color varying from the left edge to the right edge, two colors
+.PP
+.RS
+.nf

+start_color = #rrggbb opacity

+.fi
+.RE
+.SS Radial gradient, with color varying from the center to the corner, two colors:
+.PP
+.RS
+.nf
+gradient = radial
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+.fi
+.RE
+.SS Adding extra color stops (0% and 100% remain fixed, more colors at x% between the start and end control points)

+It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).</p><p>Features:</p>
+<ul>
+<li>Panel with taskbar, system tray, clock and launcher icons;</li>
+<li>Easy to customize: color/transparency on fonts, icons, borders and backgrounds;</li>
+<li>Pager like capability: move tasks between workspaces (virtual desktops), switch between workspaces;</li>
+<li>Multi-monitor capability: create one panel per monitor, showing only the tasks from the current monitor;</li>
+<li>Customizable mouse events.</li>
+</ul>
+<p>Goals:</p>
+<ul>
+<li>Be unintrusive and light (in terms of memory, CPU and aesthetic);</li>
+<li>Follow the freedesktop.org specifications;</li>
+<li>Make certain workflows, such as multi-desktop and multi-monitor, easy to use.</li>

+<h3 id="introduction">Introduction<a name="introduction" href="#introduction" class="md2man-permalink" title="permalink"></a></h3><p>These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface <code>tint2conf</code>.</p><p>The first time you run tint2, it will create the config file in <code>$HOME/.config/tint2/tint2rc</code> (This applies if you have done a clean install. Running tint2 in the source directory without doing &#39;make install&#39; will not create the config file.)</p><p>You can also specify another file on the command line with the -c option, e.g.: <code>tint2 -c $HOME/tint2.conf</code>. This can be used to run multiple instances of tint2 that use different settings.</p><p>If you change the config file while tint2 is running, the command <code>killall -SIGUSR1 tint2</code> will force tint2 to reload it.</p><p>All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.</p><h3 id="backgrounds-and-borders">Backgrounds and borders<a name="backgrounds-and-borders" href="#backgrounds-and-borders" class="md2man-permalink" title="permalink"></a></h3><p>The tint2 config file starts with the options defining background elements with borders:</p>
+<ul>
+<li><p><code>rounded = number_of_pixels</code> : the corner radius</p></li>
+<li><p><code>border_width = integer</code> : the border width in pixels</p></li>
+<li><p><code>border_sides = LRTB</code> : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used.</p></li>
+<li><p><code>background_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).</li>
+</ul></li>
+<li><p><code>border_color = color opacity</code></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+<li><p><code>background_color_hover = color opacity</code> (default: same as background_color) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>
+</ul></li>
+<li><p><code>border_color_hover = color opacity</code> (default: same as border_color) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+<li><p><code>background_color_pressed = color opacity</code> (default: same as background<em>color</em>hover) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)</li>
+</ul></li>
+<li><p><code>border_color_pressed = color opacity</code> (default: same as border<em>color</em>hover) <em>(since 0.12.3)</em></p>
+<ul>
+<li><code>color</code> is specified in hex RGB, e.g. #ff0000 is red</li>
+<li><code>opacity</code> varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque</li>
+</ul></li>
+</ul>
+<p>You can define as many backgrounds as you want. For example, the following config defines two backgrounds:</p><pre class="highlight plaintext"><code>rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+</code></pre>
+<p>tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:</p><pre class="highlight plaintext"><code>panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+</code></pre>
+<p>Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.</p><h3 id="panel">Panel<a name="panel" href="#panel" class="md2man-permalink" title="permalink"></a></h3>
+<ul>
+<li><p><code>panel_items = LTSBC</code> defines the items tint2 will show and the order of those items. Each letter refers to an item, defined as:</p>
+<ul>
+<li><code>L</code> shows the Launcher</li>
+<li><code>T</code> shows the Taskbar</li>
+<li><code>S</code> shows the Systray (also called notification area)</li>
+<li><code>B</code> shows the Battery status</li>
+<li><code>C</code> shows the Clock</li>
+<li><code>F</code> adds an extensible spacer (freespace). Has no effect if <code>T</code> is also present. <em>(since 0.12)</em></li>
+<li><code>E</code> adds an executor plugin. You can specify more than one. <em>(since 0.12.4)</em></li>
+</ul>
+<p>For example, <code>panel_items = STC</code> will show the systray, the taskbar and the clock (from left to right).</p></li>
+<li><p><code>panel_monitor = monitor (all or 1 or 2 or ...)</code> : Which monitor tint2 draws the panel on</p>
+<ul>
+<li>The first monitor is <code>1</code></li>
+<li>Use <code>panel_monitor = all</code> to get a separate panel per monitor</li>
+</ul></li>
+<li><p><code>primary_monitor_first = boolean (0 or 1)</code> : Place the primary monitor before all the other monitors in the list. <em>(since 0.12.4)</em></p></li>
+</ul>
+<p><img src="panel_padding.jpg" alt=""></p>
+<ul>
+<li><p><code>panel_position = vertical_position horizontal_position orientation</code></p>
+<ul>
+<li><code>vertical_position</code> is one of: <code>bottom</code>, <code>top</code>, <code>center</code></li>
+<li><code>horizontal_position</code> is one of: <code>left</code>, <code>right</code>, <code>center</code></li>
+<li><code>orientation</code> is one of: <code>horizontal</code>, <code>vertical</code></li>
+</ul></li>
+<li><p><code>panel_size = width height</code></p>
+<ul>
+<li><code>width</code> and <code>height</code> can be specified without units (e.g. <code>123</code>) as pixels, or followed by <code>%</code> as percentages of the monitor size (e.g. <code>50%</code>). Use <code>100%</code> for full monitor width/height.
+Example:</li>
+</ul></li>
+</ul>
+<pre class="highlight plaintext"><code># The panel's width is 94% the size of the monitor, the height is 30 pixels:
+panel_size = 94% 30
+</code></pre>
+
+<ul>
+<li><code>panel_margin = horizontal_margin vertical_margin</code> : The margins define the distance between the panel and the horizontal/vertical monitor edge. Use <code>0</code> to obtain a panel with the same size as the edge of the monitor (no margin).</li>
+</ul>
+<p><img src="panel_size_margin.jpg" alt=""></p>
+<ul>
+<li><code>panel_padding = horizontal_padding vertical_padding spacing</code> : Please refer to the image below.</li>
+</ul>
+<p><img src="panel_padding.jpg" alt=""></p>
+<ul>
+<li><p><code>font_shadow = boolean (0 or 1)</code></p></li>
+<li><p><code>panel_background_id = integer</code> : Which background to use for the panel.</p></li>
+<li><p><code>wm_menu = boolean (0 or 1)</code> : Defines if tint2 forwards unhandled mouse events to your window manager. Useful for window managers such as openbox, which display the start menu if you right click on the desktop.</p></li>
+<li><p><code>panel_dock = boolean (0 or 1)</code> : Defines if tint2 is placed into the window manager&#39;s dock. For the openbox window manager it is advised to also use a modifier for the moveButton option, otherwise the mouse click is not forwarded to tint2 (in ~/.config/openbox/rc.xml).</p></li>
+<li><p><code>panel_layer = bottom/normal/top</code> : Places tint2 into the bottom/normal/top layer. This is helpful for specifying if the panel can be covered by other windows or not. The default is the bottom layer, but with real transparency normal or top layer may be a nice alternative.</p></li>
+<li><p><code>strut_policy = follow_size/minimum/none</code> : STRUTs are used by the window manager to decide the size of maximized windows. Note: on multi-monitor (Xinerama) setups, the panel must be placed at the edge (not in the middle) of the virtual screen for this to work correctly.</p>
+<ul>
+<li><code>follow_size</code> means that the maximized windows always resize to have a common edge with tint2.</li>
+<li><code>minimum</code> means that the maximized windows always expand to have a common edge with the hidden panel. This is useful if the <code>autohide</code> option is enabled.</li>
+<li><code>none</code> means that the maximized windows use the full screen size.</li>
+</ul></li>
+<li><p><code>panel_window_name = string</code> : Defines the name of the panel&#39;s window. Default: &#39;tint2&#39;. <em>(since 0.12)</em></p></li>
+<li><p><code>disable_transparency = boolean (0 or 1)</code> : Whether to disable transparency instead of detecting if it is supported. Useful on broken graphics stacks. <em>(since 0.12)</em></p></li>
+<li><p><code>mouse_effects = boolean (0 or 1)</code> : Whether to enable mouse hover effects for clickable items. <em>(since 0.12.3)</em></p></li>
+<li><p><code>mouse_hover_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)</code> : Adjusts the icon color and transparency on mouse hover (works only when mouse_effects = 1).` <em>(since 0.12.3)</em></p></li>
+<li><p><code>mouse_pressed_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)</code> : Adjusts the icon color and transparency on mouse press (works only when mouse_effects = 1).` <em>(since 0.12.3)</em></p></li>
+<li><p><code>autohide = boolean (0 or 1)</code> : Whether to enable panel hiding when the mouse cursor exists the panel.</p></li>
+<li><p><code>autohide_show_timeout = float</code> : Show timeout in seconds after the mouse cursor enters the panel. Use &#39;.&#39; as decimal separator.</p></li>
+<li><p><code>autohide_hide_timeout = float</code> : Hide timeout in seconds after the mouse cursor exits the panel. Use &#39;.&#39; as decimal separator.</p></li>

+# TINT2 1 "2017-04-23" 0.14.2
+
+## NAME
+tint2 - lightweight panel/taskbar
+
+## DESCRIPTION
+tint2 is a simple panel/taskbar made for modern X window managers.
+It was specifically made for Openbox but it should also work with other window managers (GNOME, KDE, XFCE etc.).
+
+Features:
+
+  * Panel with taskbar, system tray, clock and launcher icons;
+  * Easy to customize: color/transparency on fonts, icons, borders and backgrounds;
+  * Pager like capability: move tasks between workspaces (virtual desktops), switch between workspaces;
+  * Multi-monitor capability: create one panel per monitor, showing only the tasks from the current monitor;
+  * Customizable mouse events.
+
+Goals:
+
+  * Be unintrusive and light (in terms of memory, CPU and aesthetic);
+  * Follow the freedesktop.org specifications;
+  * Make certain workflows, such as multi-desktop and multi-monitor, easy to use.
+

+
+### Introduction
+
+These are instructions for configuring tint2 directly by editing its config file.
+You may also use instead the graphical interface `tint2conf`.
+
+The first time you run tint2, it will create the config file in `$HOME/.config/tint2/tint2rc` (This applies if you have done a clean install. Running tint2 in the source directory without doing 'make install' will not create the config file.)
+
+You can also specify another file on the command line with the -c option, e.g.: `tint2 -c $HOME/tint2.conf`. This can be used to run multiple instances of tint2 that use different settings.
+
+If you change the config file while tint2 is running, the command `killall -SIGUSR1 tint2` will force tint2 to reload it.
+
+All the configuration options supported in the config file are listed below.
+Try to respect as much as possible the order of the options as given below.
+
+### Backgrounds and borders
+
+The tint2 config file starts with the options defining background elements with borders:
+
+  * `rounded = number_of_pixels` : the corner radius
+
+  * `border_width = integer` : the border width in pixels
+
+  * `border_sides = LRTB` : the sides to draw the border on (left, right, top, bottom). If not specified, all sides are used. *(since 0.12.12)*
+
+  * `background_color = color opacity`
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz).
+
+  * `border_color = color opacity`
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+  * `background_color_hover = color opacity` (default: same as `background_color`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)
+
+  * `border_color_hover = color opacity` (default: same as `border_color`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+  * `background_color_pressed = color opacity` (default: same as `background_color_hover`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque. Note that for a transparent panel you need to enable a desktop compositor (such as compton or compiz)
+
+  * `border_color_pressed = color opacity` (default: same as `border_color_hover`) *(since 0.12.3)*
+    * `color` is specified in hex RGB, e.g. #ff0000 is red
+    * `opacity` varies from (0 to 100), where 0 is fully transparent, 100 is fully opaque
+
+You can define as many backgrounds as you want. For example, the following config defines two backgrounds:
+
+```
+rounded = 1
+border_width = 0
+background_color = #282828 100
+border_color = #000000 0
+
+rounded = 1
+border_width = 0
+background_color = #f6b655 90
+border_color = #cccccc 40
+```
+
+tint2 automatically identifies each background with a number starting from 1 (1, 2, ...).
+Afterwards, you can apply a background to objects (panel, taskbar, task, clock, systray) using the background id, for example:
+
+```
+panel_background_id = 1
+taskbar_background_id = 0
+task_background_id = 0
+task_active_background_id = 2
+systray_background_id = 0
+clock_background_id = 0
+```
+
+Identifier 0 refers to a special background which is fully transparent, identifier 1 applies the first background defined in the config file etc.
+
+### Gradients
+
+(Available since 0.13.0)
+
+Backgrounds also allow specifying gradient layers
+that are drawn on top of the solid color background.
+
+First the user must define one or more gradients in the config file,
+each starting with `gradient = TYPE`. These must be added before backgrounds.
+
+Then gradients can be added by index to backgrounds,
+using the `gradient_id = INDEX`, `gradient_id_hover = INDEX` and
+`gradient_id_pressed = INDEX`, where `INDEX` is
+the gradient index, starting from 1.
+
+#### Gradient types
+
+Gradients vary the color between fixed control points:
+* vertical gradients: top-to-bottom;
+* horizontal gradients: left-to-right;
+* radial gradients: center-to-corners.
+
+The user must specify the start and end colors, and can optionally add extra color stops in between
+using the `color_stop` option, as explained below.
+
+##### Vertical gradient, with color varying from the top edge to the bottom edge, two colors
+
+```
+gradient = vertical
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Horizontal gradient, with color varying from the left edge to the right edge, two colors
+
+```
+gradient = horizontal
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Radial gradient, with color varying from the center to the corner, two colors:
+
+```
+gradient = radial
+start_color = #rrggbb opacity
+end_color = #rrggbb opacity
+```
+
+##### Adding extra color stops (0% and 100% remain fixed, more colors at x% between the start and end control points)
+
+```
+color_stop = percentage #rrggbb opacity
+```
+
+#### Gradient examples
+
+```
+# Gradient 1: thin film effect
+gradient = horizontal
+start_color = #111122 30
+end_color = #112211 30
+color_stop = 60 #221111 30
+
+# Gradient 2: radial glow
+gradient = radial
+start_color = #ffffff 20
+end_color = #ffffff 0
+
+# Gradient 3: elegant black
+gradient = vertical
+start_color = #444444 100
+end_color = #222222 100
+
+# Gradient 4: elegant black
+gradient = horizontal
+start_color = #111111 100
+end_color = #222222 100
+
+# Background 1: Active desktop name
+rounded = 2
+border_width = 1
+border_sides = TBLR
+background_color = #555555 10
+border_color = #ffffff 60
+background_color_hover = #555555 10
+border_color_hover = #ffffff 60
+background_color_pressed = #555555 10
+border_color_pressed = #ffffff 60
+gradient_id = 3
+gradient_id_hover = 4
+gradient_id_pressed = 2
+
+[...]
+```
+
+### Panel
+
+  * `panel_items = LTSBC` defines the items tint2 will show and the order of those items. Each letter refers to an item, defined as:
+    * `L` shows the Launcher
+    * `T` shows the Taskbar
+    * `S` shows the Systray (also called notification area)
+    * `B` shows the Battery status
+    * `C` shows the Clock
+    * `F` adds an extensible spacer (freespace). You can specify more than one. Has no effect if `T` is also present. *(since 0.12)*
+    * `E` adds an executor plugin. You can specify more than one. *(since 0.12.4)*
+    * `P` adds a push button. You can specify more than one. *(since 0.14)*
+    * `:` adds a separator. You can specify more than one. *(since 0.13.0)*
+
+    For example, `panel_items = STC` will show the systray, the taskbar and the clock (from left to right).
+
+  * `panel_monitor = monitor (all or 1 or 2 or ...)` : Which monitor tint2 draws the panel on
+    * The first monitor is `1`
+    * Use `panel_monitor = all` to get a separate panel per monitor
+
+  * `primary_monitor_first = boolean (0 or 1)` : Place the primary monitor before all the other monitors in the list. *(since 0.12.4)*
+
+![](images/panel_padding.jpg)
+
+  * `panel_position = vertical_position horizontal_position orientation`
+    * `vertical_position` is one of: `bottom`, `top`, `center`
+    * `horizontal_position` is one of: `left`, `right`, `center`
+    * `orientation` is one of: `horizontal`, `vertical`
+
+  * `panel_size = width height`
+    * `width` and `height` can be specified without units (e.g. `123`) as pixels, or followed by `%` as percentages of the monitor size (e.g. `50%`). Use `100%` for full monitor width/height.
+      Example:
+
+```
+# The panel's width is 94% the size of the monitor, the height is 30 pixels:
+panel_size = 94% 30
+```
+
+  * `panel_shrink = boolean (0 or 1)` : If set to 1, the panel will shrink to a compact size dynamically. *(since 0.13)*
+
+  * `panel_margin = horizontal_margin vertical_margin` : The margins define the distance between the panel and the horizontal/vertical monitor edge. Use `0` to obtain a panel with the same size as the edge of the monitor (no margin).
+
+![](images/panel_size_margin.jpg)
+
+  * `panel_padding = horizontal_padding vertical_padding spacing` : Please refer to the image below.
+
+![](images/panel_padding.jpg)
+
+  * `font_shadow = boolean (0 or 1)`
+
+  * `panel_background_id = integer` : Which background to use for the panel.
+
+  * `wm_menu = boolean (0 or 1)` : Defines if tint2 forwards unhandled mouse events to your window manager. Useful for window managers such as openbox, which display the start menu if you right click on the desktop.
+
+  * `panel_dock = boolean (0 or 1)` : Defines if tint2 is placed into the window manager's dock. For the openbox window manager it is advised to also use a modifier for the moveButton option, otherwise the mouse click is not forwarded to tint2 (in ~/.config/openbox/rc.xml).
+
+  * `panel_layer = bottom/normal/top` : Places tint2 into the bottom/normal/top layer. This is helpful for specifying if the panel can be covered by other windows or not. The default is the bottom layer, but with real transparency normal or top layer may be a nice alternative.
+
+  * `strut_policy = follow_size/minimum/none` : STRUTs are used by the window manager to decide the size of maximized windows. Note: on multi-monitor (Xinerama) setups, the panel must be placed at the edge (not in the middle) of the virtual screen for this to work correctly.
+    * `follow_size` means that the maximized windows always resize to have a common edge with tint2.
+    * `minimum` means that the maximized windows always expand to have a common edge with the hidden panel. This is useful if the `autohide` option is enabled.
+    * `none` means that the maximized windows use the full screen size.
+
+  * `panel_window_name = string` : Defines the name of the panel's window. Default: 'tint2'. *(since 0.12)*
+

+
+  * `mouse_effects = boolean (0 or 1)` : Whether to enable mouse hover effects for clickable items. *(since 0.12.3)*
+
+  * `mouse_hover_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the icon color and transparency on mouse hover (works only when mouse_effects = 1).` *(since 0.12.3)*
+
+  * `mouse_pressed_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the icon color and transparency on mouse press (works only when mouse_effects = 1).` *(since 0.12.3)*
+
+  * `autohide = boolean (0 or 1)` : Whether to enable panel hiding when the mouse cursor exists the panel.
+
+  * `autohide_show_timeout = float` : Show timeout in seconds after the mouse cursor enters the panel. Use '.' as decimal separator.
+
+  * `autohide_hide_timeout = float` : Hide timeout in seconds after the mouse cursor exits the panel. Use '.' as decimal separator.
+
+  * `autohide_height = integer` : panel height (width for vertical panels) in hidden mode.
+
+### Launcher
+  * `launcher_item_app = path_to_application` : Each `launcher_item_app` must be a file path to a .desktop file following the freedesktop.org [specification](http://standards.freedesktop.org/desktop-entry-spec/desktop-entry-spec-latest.html). The paths may begin with `~`, which is expanded to the path of the user's home directory. If only a file name is specified, the file is search in the standard application directories (`$XDG_DATA_HOME/applications`, `~/.local/share/applications`, `$XDG_DATA_DIRS/applications`, `/usr/local/share/applications`, `/usr/share/applications`, `/opt/share/applications`).
+
+  * `launcher_apps_dir = path_to_directory` : Specifies a path to a directory from which the launcher is loading all .desktop files (all subdirectories are explored recursively). Can be used multiple times. The path may begin with `~`, which is expanded to the path of the user's home directory. *(since 0.12)*
+
+  * `launcher_background_id = integer` : Defines which background to use.
+
+  * `launcher_icon_background_id = integer` : Defines which background to use for icons.
+
+  * `launcher_padding = horizontal_padding vertical_padding spacing`
+
+  * `launcher_icon_size = integer` : The launcher icon size, in pixels.
+
+  * `launcher_icon_theme = name_of_theme` : (Optional) Uses the specified icon theme to display shortcut icons. Note that tint2 will detect and use the icon theme of your desktop if you have an XSETTINGS manager running (which you probably do), unless `launcher_icon_theme_override = 1`.
+
+  * `launcher_icon_theme_override = boolean (0 or 1)` : Whether `launcher_icon_theme` overrides the value obtained from the XSETTINGS manager. *(since 0.12)*

+
+  * `taskbar_hide_different_monitor = boolean (0 or 1)` :  If enabled, the taskbar shows only the tasks from the current monitor. Useful when running different tint2 instances on different monitors, each one having its own config. *(since 0.12)*
+
+  * `taskbar_always_show_all_desktop_tasks = boolean (0 or 1)` :  Has effect only if `taskbar_mode = multi_desktop`. If enabled, tasks that appear on all desktops are shown on all taskbars. Otherwise, they are shown only on the taskbar of the current desktop. *(since 0.12.4)*
+

+
+  * `taskbar_name_active_font_color = color opacity (0 to 100)` :  Font color for the name of the current desktop.
+
+# Taskbar buttons
+
+The following options configure the task buttons in the taskbar:
+
+  * `task_icon = boolean (0 or 1)` : Whether to display the task icon. There is no explicit option to control the task icon size; it depends on the vertical padding set with `task_padding`.

+  * `task_STATUS_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjusts the task icon's color and transparency.
+
+  * `task_STATUS_background_id = integer` : Which background to use for the task.
+
+### Mouse actions for taskbar buttons
+
+The possible mouse events are: `left, middle, right, scroll_up, scroll_down`.
+
+The possible mouse actions are: `none, close, toggle, iconify, shade, toggle_iconify, maximize_restore, desktop_left, desktop_right, next_task, prev_task`.
+
+Use `mouse_event = action` to customize mouse actions. Example:

+  mouse_scroll_up = toggle
+  mouse_scroll_down = iconify
+```
+
+The action semantics:

+  * `systray_padding = horizontal_padding vertical_padding spacing`
+
+  * `systray_background_id = integer` : Which background to use.
+
+  * `systray_sort = ascending/descending/left2right/right2left` : Specifies the sorting order for the icons in the systray: in ascending/descending alphabetical order of the icon title, or always add icons to the right/left (note that with `left2right` or `right2left` the order can be different on panel restart).
+
+  * `systray_icon_size = max_icon_size` : Set the maximum system tray icon size to `number`. Set to `0` for automatic icon sizing.
+
+  * `systray_icon_asb = alpha (0 to 100) saturation (-100 to 100) brightness (-100 to 100)` : Adjust the systray icons color and transparency.
+

+
+### Clock
+
+  * `time1_format = %H:%M` : The format used by the first line of the clock.
+    * `time1_format`, `time2_format` and `clock_tooltip` use the 'strftime' syntax. More info can be found here: http://www.manpagez.com/man/3/strftime/
+    * To hide the clock, comment `time1_format` and `time2_format`.
+
+  * `time1_timezone = :US/Hawaii`
+    * `time1_timezone`, `time2_timezone` and `clock_tooltip_timezone` can be used to specify a timezone. If you do not specify a value the system-wide timezone is used. The timezones can usually be found in `/usr/share/zoneinfo`. If your timezones are in a different directory, you need to specify the absolute path, e.g. `time1_timezone = :/different/zoneinfo/dir/US/Hawaii` Always prepend the timezone with a ':'
+
+  * `time1_font = [FAMILY-LIST] [STYLE-OPTIONS] [SIZE]`
+
+  * `time2_format = %A %d %B`
+
+  * `time2_timezone = :Europe/Berlin`
+

+Description: lightweight taskbar
+ Tint is a simple panel/taskbar intentionally made for openbox3, but should
+ also work with other window managers. The taskbar includes transparency and
+ color settings for the font, icons, border, and background. It also supports
+ multihead setups, customized mouse actions, and a built-in clock. Tint was
+ originally based on ttm code. Since then, support has also been added
+ for a battery monitor and system tray.
+ .
+ The goal is to keep a clean and unintrusive look with lightweight code and
+ compliance with freedesktop specification.
