### LAZYTREE and LISTCONTROL Methods
|
|
DEFAULTICONSIZE = 16
|
|
|
|
def SetupIcons(self, images=(), size=None):
|
|
self.__size = size or self.DEFAULTICONSIZE
|

### Local methods...
|
|

|
|

|
|

|
|

|
|
else:
|
|

|
|

|
|

|
|
"expected wx.Icon or wx.Bitmap" % (icon))
|
|

|
|

|
|
|
|
### Customisation point...
|
|
def GetIcon( self, node ):
|
|
'''Get the actual icon object for a node'''
|
|
if hasattr (node,"DIAGRAMICON"):
|
|
return node.DIAGRAMICON
