Xfce splash screen crash course
Here's a very brief introduction to the way splash screens work in Xfce 4.2.0 and above:
The whole splash thingy is a bit complex atm. On the first level, there are splash engines (currently
balou); these are loadable modules.
mice isn't themable at all, everything's hardcoded.
simple is themeable from the configure dialog, and
balou is themable using a theme file.
balou theming is pretty easy, its just a
themerc file and a logo image file. Check the
Default balou theme in the xfce4-session source to get an idea of the file format/content (it includes a few comments). To distribute a theme, create a directory layout like this:
Name Name/balou Name/balou/themerc Name/balou/logo.png
Name is the name of your theme. Then tar up the stuff like this:
tar czvf Name.tar.gz Name
Now users can simply install the theme by dragging the
.tar.gz file from a file manager and dropping it to the
balou configure screen in the settings manager.
