hardcoding the look of any widgets is definitely bad style and shouldn't
be done. That's what themes and gtkrc files were designed for: let the
user override the look to make it fit her preferences and her needs.
What you can do is to distribute your application with a custom gtkrc
file that is installed along with it. Then let your application read that
custom gtkrc on startup by calling gtk_rc_parse() explicitely.

as I said, the window decorations are nothing more than a hack in
GTK+. It's not configurable and doesn't respect any theme settings. It
shouldn't be too hard to change it but at the moment neither Alexander
Larsson nor me have the time or motivation to improve it.

There are a couple of parameters you can set in /etc/directfbrc or
~/.directfbrc that control how the background is handled:
bg-none
Disable background clear.
bg-color=AARRGGBB
Use background color (hex).
bg-image=<filename>
Use background image.
bg-tile=<filename>
Use tiled background image.

what kind of mouse are you using?

see above.

sure, what should keep you from doing so?

that's a pure GTK+ question. Have you checked the example code /
tutorial that comes with the GTK+ (and GTK+-DirectFB) source?
Salut, Sven
