Re: drawing area & multithreading

[Giaslas Georgios <giaslas ceid upatras gr>]

i have tried that.
actually i call gdk_flush() either after gtk_widget_draw() or after
gdk_draw_rectangle inside the expose event.
in both cases i get the following error:
Xlib: unexpected async reply

is there any other way?

thanks
