gdk_draw_layout seems that it doesn't make damage event for offscreens.

Hello guys.

 

I'm new.

Currently I'm making some customized widgets with GTK+-2.18.

To test performance about my customized widget, I'm using "gtkperf".

But a problems running gtkperf.

 

"gdk_draw_layout seems that it doesn't make damage event for offscreens"

 

When we usually call gdk_draw_xxx functions, gdk_draw_xxx functions draw something by gdk_offscreen_window_draw_xxx which make damage events when drawing is done.

But gdk_draw_layout doesn't draw layout through gdkoffscreenwindow. PangoRenderer directly draw layout on offscreen.

So If I use gdk_draw_layout, I can't catch when I move the picture of offscreen into onscreen.

 

I wonder whether this problem is the known issue or not.

Or I just made misunderstanding.

 

Best Regards

Boram
