Hi there,

I have the following program:
SuperStrict

Local MyWindow:TGadget=CreateWindow("Canvas Example", 200,200,320,240)
Local MyCanvas:TGadget=CreateCanvas(0,0,ClientWidth(MyWindow),ClientHeight(MyWindow),MyWindow)
SetGadgetLayout MyCanvas,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED,EDGE_ALIGNED
Repeat
  WaitEvent()
  Select EventID()
  Case EVENT_WINDOWCLOSE
     End
  Case EVENT_GADGETPAINT
    SetGraphics CanvasGraphics (MyCanvas)
	Cls
    DrawRect  20,20,50,80
    Flip
   End Select
Forever


Problem is: when I resize I have garbage on the bottom and on the right of the canvas... I think the real canvas zone is not resized but I am not able to tweak this program to make it work....

Can somebody help me?

thanks in advance.
