wxPython auinotebook.GetSelection() return index to the first page.

Question

Why do 'GetSelection()' return the index to the first page and not the last created in 'init' and 'new_panel'? It do return correct index in the 'click' method.

The output should be 0 0 1 1 2 2, but mine is 0 0 0 0 0 0.

Running latest version of python and wxpython in ArchLinux.

Answer 1

I ran your example and got the correct output:

0
0
1
1
2
2

I'm using the latest windows release of wxPython

Answer 2

The solution was pretty simple. The problem seemed to be that creating the new page didn't generate a page change event. The solution is:

self.nb.AddPage(pnl, nm, select=True)

Adding 'select=True' will trigger a page change event. So problem solved.

Another solution is to add this line:

self.nb.SetSelection(self.nb.GetPageCount()-1)

They both do the same. Trigger a page change event to the last added page.

def new_panel(self, nm):
        pnl = wx.Panel(self)
        pnl.identifierTag = nm
        self.nb.AddPage(pnl, nm, select=True) 
        self.sizer = wx.BoxSizer()
        self.sizer.Add(self.nb, 1, wx.EXPAND)
        self.SetSizer(self.sizer)
        #self.nb.SetSelection(self.nb.GetPageCount()-1)
        pnl.SetFocus() # Have focused the last panel.
        print self.nb.GetSelection()
