double call in EVT_NOTEBOOK_PAGE_CHANGED

wxPython Users

Hello,

Im using EVT_NOTEBOOK_PAGE_CHANGED. I have a wx.Notebook, self.NBook,
with 2 tabs and Id like to call a dialog when a tab’s change occur. So I use the following lines:

self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.changeTab,self.NBook)
…
…
And inside changeTab( ), I use

        if ( self.NBook.GetSelection( ) == 0 ): # to control when it is in the first Tab.

            dlg = wx.MessageDialog(self, info_text, " INFO Note",
                           wx.YES_NO| wx.ICON_INFORMATION|wx.ICON_QUESTION)
   
       
            if(dlg.ShowModal() == wx.ID_YES):
       
                dlg.ShowModal()
                dlg.Destroy()

            # and some code in here

And my problem is that, i dont know why, I get the dialog window twice ! ! ! It seems its calling the event
before the change was completely done. Any Idea?

Thanks in advance!

Leticia.

Hi Leticia,

Im using EVT_NOTEBOOK_PAGE_CHANGED. I have a wx.Notebook, self.NBook,
with 2 tabs and Id like to call a dialog when a tab's change occur. So I use
the following lines:

   self.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.changeTab,self.NBook)

Try this:

self.NBook.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.changeTab)

Not sure if it will work, but if my memory serves well the reason is here:
