NoteBook hide/disable page failed

I have a Notebook in wxpython:

self.book = wx.Notebook(self, -1, style=0)
self.book.AddPage(self.book_a,_("a"))
self.book.AddPage(self.book_b,_("b"))

This code works fine. Evrything is as it should.

The thing is that I have later a condition if x==1: that if it's true I need to hide/disable book_b page (preferbly disable).

i wrote this code:

if  x==1:
    self.book_a.Hide()

but nothing happend. Then I tried:

if  x==1:
    self.book_a.Disable()

but also nothing happend.

If I do:

print self.book_a.Hide()
print self.book_a.Disable()

it returns

False
False

I know it means the operation faild and that why I don't see any change but I couldn't find in google or elsewhere when Hide() or Disable() return False.

Does anyone know what is the problem or in what cases Hide() or Disable() return false?

The wx.Notebook widget doesn't support disabling pages. The only workaround would be to check which tab is being clicked on and if it is "disabled", veto the event (EVT_NOTEBOOK_PAGE_CHANGING or EVT_NOTEBOOK_PAGE_CHANGED).

There is an alternative though. You can use the FlatNotebook widget or the AUI Notebook from wx.lib.agw (wx.aui's Notebook does not support this that I know of). They both support the the ability to disable a tab. There are examples of both of these widgets in the wxPython demo.

I have some examples of these controls here as well:

UPDATE - I just tried disabling a page. While it doesn't stop the user from clicking on the tab, it DOES disable all the controls on that page:

import wx

########################################################################
class TabPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)

        text = wx.TextCtrl(self)


########################################################################
class MainPanel(wx.Panel):
    """"""

    #----------------------------------------------------------------------
    def __init__(self, parent):
        """Constructor"""
        wx.Panel.__init__(self, parent)
        notebook = wx.Notebook(self)

        tab_one = TabPanel(notebook)
        notebook.AddPage(tab_one, "Tab One")

        tab_two = TabPanel(notebook)
        tab_two.Disable()
        notebook.AddPage(tab_two, "Tab Two")

        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(notebook, 1, wx.ALL|wx.EXPAND, 5)
        self.SetSizer(sizer)



########################################################################
class MainFrame(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Notebooks")
        panel = MainPanel(self)

        self.Show()

if __name__ == '__main__':
    app = wx.App(False)
    frame = MainFrame()
    app.MainLoop()
