Re: Flickering display (using RGB buffer to write on a DrawingArea)

["Konstantin Evdokimenko" <qewerty gmail com>]

Use this on your expose event callback.

gdk_window_begin_paint_rect(widget->window, & rect);

/* Draw something */

gdk_window_end_paint(widget->window);

And make sure that widget is double buffered (by default).

Look at gtk_widget_set_double_buffered function.
