mark_paint_from_clip


Description:

[ Version ( since = "3.16" ) ]
public void mark_paint_from_clip (Context cr)

If you call this during a paint (e.

g. between begin_paint_region and end_paint then GDK will mark the current clip region of the window as being drawn. This is required when mixing GL rendering via cairo_draw_from_gl and cairo rendering, as otherwise GDK has no way of knowing when something paints over the GL-drawn regions.

This is typically called automatically by GTK+ and you don't need to care about this.

Parameters:

this

a Window

cr

a Context
