[Tile-dev] chasing arrows element

[Mats B. <ma...@pr...>]

Dear all,

I have produced a chasing arrows element that is supposed to be stub linked to tile.
The widget (element) is native on aqua, used by Firefox/Thunderbird on all platforms, 
and in some of Googles web interfaces (Google Analytic). 
It is very useful for client developers and I think it should be a part of any toolkit.

It has four "themes":
 o Tk drawing used as fallback
 o native aqua on Mac
 o cairo graphics on X11
 o gdi+ on XP+

I'v tried to load the cairo and gdi+ dynamically similar to how tile uses uxtheme.dll.
The Tk drawing is a bit primitive since it is nearly impossible to make anything look
nice on 16x16 without antialiasing.

Problems still not solved (which I'd appreciate getting help with):
 o Can't figure out how to do themed backgrounds on windows (XP)
 o Panics on XP complaining about a palette?
 o Build systems probably need to be better (unix: TEA; win: VC++7; Mac: PB).
 
I'm not sure I've got the ttk stub linking OK since I got crashes on the first Ttk call
after Ttk_InitStubs() if I used a different tile than the stub version.

Cvs contains prebuilt shared libs. Get it all using:
cvs -d:pserver:ano...@tc...:/cvsroot/tclbitprint login 
cvs -z3 -d:pserver:ano...@tc...:/cvsroot/tclbitprint co -P chasingarrows

I'll be glad to add any contributers.
