In the wx demoy TreeCtrl.py I find the following code, that should
have no effect but seems to be needed nevertheless.
class TestTreeCtrlPanel(wx.Panel):
def __init__(self, parent, log):
[...}
self.tree = MyTreeCtrl(self, tID, wx.DefaultPosition, ...
isz = (16,16)
il = wx.ImageList(isz[0], isz[1])
fldridx = il.Add(wx.ArtProvider_GetBitmap(wx.ART_FOLDER, wx.ART...
[...]
self.tree.SetImageList(il)
--> self.il = il
What is the effect of the last statement? self.il is not used
anywhere. I used similar code in my application and it crashes unless
I assign the image list to the parent panel. The name of the attribute
does not seem to matter. I can write self.foo=il just as well, but
without it it crashes.
