from Mike about Cairo and semi-transaprent windows. I did the same work a while ago to make Gnome Launch box
have nice RGBA *bling bling*. Since we some to get a lot of duplicated code here I really whish we had that directly in gtk. Also a gdk_compositor_is_running or something like that would be very very nice. I know there is a way for some window managers (e.g. metacity) to tell you (over selections and stuff) but having that in gdk/gtk would be way nicer. The real reason I blog though is LbFrame.
It is basically a frame with round corners
which can also handle transparency
if the compositor is running. Now with Xgl and AiglX maybe more people are interested to use it or use it as a starting point for their own widgets. Also if you are one of the lucky ones that have fast compositing, you should really give Gnome Launch box
another try. I use it as my Alt-F2 replacement. And I have some patches in the queue to make it even more rocking!
