hello!

just go and try the following code:

Framework bah.gtkmaxgui
Import brl.eventqueue
Import brl.max2d


Local window:Tgadget = CreateWindow("test", 0, 0, 300, 300)
Local canvas:tgadget = CreateCanvas(10, 10, 200, 200, window)
SetGraphics(CanvasGraphics(canvas))
Repeat
	WaitEvent()

	Select EventID()
		Case EVENT_GADGETPAINT
			Cls()

			Flip()
	End Select

Until KeyDown(key_escape)

for me it does not work at all. error message: cls() tries to access to a null object...??
