endFrame
⚠️ Deprecated ⚠️
This is deprecated since version 4.16.
Drawing directly to the surface is no longer recommended. Use GskRenderNode and GskRenderer.
Ends a drawing operation started with gdk_draw_context_begin_frame().
This makes the drawing available on screen. See method@Gdk.DrawContext.begin_frame for more details about drawing.
When using a class@Gdk.GLContext, this function may call glFlush() implicitly before returning; it is not recommended to call glFlush() explicitly before calling this function.
