what does it mean to create widget on the stack? dynamically create widgets? if so, no. complete ui is done in fluid. and there is no widget soccer going on :) anyway, you know what? i tried different svn revisions. i went back 5 revisions and went up one by one. the first one (five earlier) was ok, the second was ok, so was the third and the fourth too! and now, all of a sudden, HEAD is working again...yay!? doesnt make me feel very comfortable. what when i reboot? hehe...oh well...what was that? hmm... weird thing is...i went to windows in between and it got the flu too. but it was a little different in windows: it worked when i launched the app in gdb. that wasnt the case in linux. but it segfaultet like in did in linux when NOT run in gdb. this is strange...isnt it? i will now go back to windows and see what i can fix there by switching svn revisions around *g* :> hey, thats at least uncomplicated ;) jan _______________________________________________ fltk mailing list [email protected] http://lists.easysw.com/mailman/listinfo/fltk
