NoteBook hide/disable page failed

Question

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?

Answer 1

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:

• http://www.blog.pythonlibrary.org/2009/12/09/the-%E2%80%9Cbook%E2%80%9D-controls-of-wxpython-part-2-of-2/

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:

        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)
