Re: Heads-up: Potentially breaking changes to the GDK drawing model pushed

[Jean Brefort <jean brefort normalesup org>]

Both abiword and gnumeric do something like:

cr = gdk_cairo_create(win);
...do some drawing
then relase the cairo.

Will this still work if we use

gdk_window_begin_paint_rect (win, rect);
cr = gdk_cairo_create (win);
...do some drawing
gdk_window_end_paint (win);

?
