I am currently using some wxPython's AuiNotebook in one of my projects and I have a problem that can't manage to solve. I think there should be a simple solution but can't manage to find it.
I have created a new class derived from wx.lib.agw.aui.AuiNotebook and I am trying to get the index of a tab at the moment it's clicked. I wrote something like that:
class NewNotebook(wx.lib.agw.aui.AuiNotebook):
# __init__ function an stuff...
def OnTabClicked(self, evt):
index = self.GetSelection()
print index
wx.lib.agw.aui.AuiNotebook.OnTabClicked(self, evt)
The aim was to capture the index of the tab clicked on and in some cases, have a special behavior, or just perform a regular click otherwise. However, I think that AuiNotebook.OnTabClicked actually changes the selection among different things. It would explain why index contains the value of the tab that was selected before the click.
I did not a find a way to get the selection of the new tab though. I looked for some information in the captured event but still could not find the one I wanted.
So, does someone know how I can get the selected tab before I call AuiNotebook.OnTabClicked?
There doesn't seem to be a builtin way to do this. The closest I found was something I helped with on the wxPython mailing list, but that had to do with double-clicking.
Here's one workaround that came to me though. When you first show the frame, set some kind of class property to the currently shown tab (i.e. self.currentTab = 0). Then catch the EVT_AUINOTEBOOK_PAGE_CHANGING or EVT_AUINOTEBOOK_PAGE_CHANGED event and update the property. For me, when I catch EVT_AUINOTEBOOK_PAGE_CHANGING, I always get the index of the tab I'm clicking on, at least on Windows.
