- Let's just have one header definining export- and visibility-
macros for Calamares. They are still selected based on the
export flags (*_PRO), just defined in one header instead of two.
- These methods are used for multi-page view-steps, which are rare.
For all the others, just drop the empty implementation and defer
to the base class.
- The screenshot stays one size, but different ThemeWidgets may overlap
partially when you shrink the screen or have more than three / four
themes listed.
- Probably needs work in the surrounding container and overall better
page-scrollbar support.
- This enables working in three modes:
- No themes listed; all are shown without screenshots,
- Themes listed, showAll false; only those are shown,
- Themes listed, showAll true; the installed-but-not-listed
themes are shown after the listed ones, and have limited info.
- Although it's not necessarily accurate for an extensively-modified
Plasma configuration, we can read the Look-and-Feel from the
configuration files. Allows auto-detection.
- For OEM modes where there is already a theme, add a preselect:
key to pick a specific theme and have that one come up as already-
selected in the list.
- Don't re-run the lnftool if an already-selected theme is clicked
again. Use toggled() instead of clicked().
It is the distro's responsibility to produce screenshots that look
good; previously I chose to preserve the aspect ratio on the grounds
that this would keep the look of the screenshot even if the distro
had done one in a weird size. This makes the screenshot part
of the LNF selection look weird, though, since then you get
blank parts.
Switch to ignoring the aspect ration; distro's should produce
screenshots in a 12x8 (i.e. 3:2) aspect ratio, preferrably at
least 120x80 pixels -- but keep in mind hiDPI and the default
font sizes of the distro, which may make other sizes look better.
(this follows discussion with BlueStar Linux)
- Since the image size isn't known a priori (due to sizing based on fonts),
load the image and then resize in all code paths.
- Use the right resizing flags.
- .. and actually use the resulting scaled pixmap.
Thanks to Jeff Hodd.
- calculate a hash of the filename, and use that
- makes it possible to distinguish different screenshots
even when the image file is missing / badly configured
- most colors will be dreadful
