Class DrawingAreaProxy

source code

The purpose of this proxy is to simplify the access to the canvas
from the MainFrame window.

Example of usage in MainFrame GuiCreator:
    def zoomout(evt):
        DrawingAreaProxy(self).zoom_out()
        
Instead of writing:
    def zoomout(evt):
        self.main_panel.timeline_panel.timeline_canvas.zoom_out()
