Hi All,
I'm creating a instance of MyPage[which is derived from ogl class] as child
of wxNoteBook .
But OnCloseWindow function is not calling __del__ of MyPage class.
I've to explicitly call that in OnCloseWindow funtion.
where is the wrong?

Hi,
I'm getting the exact memory leaks eventhough i've defined the __del__
function.
15:55:01: There were memory leaks.

I found the answer in the sample code. I must have been blind yesterday. I
don't understand why I didn't find it.
In order to clean wxOGL object, the __del__ method should be implemented as
follows:
def __del__( self ):
for shape in self.diagram.GetShapeList():
if shape.GetParent() == None:
shape.SetCanvas(None)
shape.Destroy()
self.diagram.Destroy()
Sorry for messing up the mailing list.

Subject: [wxPython] Need help on wxOGL
Hi, I'm looking for a help.
I was playing with wxOGL sample code. I copied several lines into my test
code and it worked, but when the test script quit, I got the memory leak
error message.
My rough guess from wxOGL.py example code is that I should do something
when
the window is closed.
I might be able to use the following code (from wxOGL.py), but I have no
idea what they are.
I already tied to add the following code at the end of my code, but it
didn't work.
Is there anybody to explain them?
###########################
class __Cleanup:
cleanup = wxOGLCleanUp
def __del__(self):
self.cleanup()# when this module gets cleaned up then wxOGLCleanUp() will get called
__cu = __Cleanup()#############################
I also tried to manually clearn up wxOGL object by adding the Destroy()
method into my wxShapeCanvas object as follows:
def Destroy( self ):
wxOGLCleanUp()
wxShapeCanvas.Destroy()But neither worked.
Thanks in advance.
YJ
