wxListBox and non-selectable item

Hi all,

sorry for a newbie question, is there a way how to make item in
wxListBox non-selectable, to disable an item? I checked
SetItemState(), but I haven't found how this could be implemented.

Thanks in advance! Martin

wx.ListBox does not allow different fonts for different items, and I don’t know enough of wx.ListBox to advise you. My crude solution, with wx,ListBox, would be to add to the wx.ListBox a tooltip (see wx.ToolTip) saying “The item x cannot be selected”. Bye

Hi,

thanks, works like a charm. I forgot to mention that I would like to
visually separate selectable and non-selectable items, e.g. grey
coloured font for non-selectable items. I wonder if wx.ListBox enables

that, or do I need wx.ListCtrl instead?

Thanks, Martin

Possible. You declare at the beginning of the frame class a general

variable:
FormerSelection = wx.NOT_FOUND

Intercept in init the event wx.EVT_LISTBOX with the code:
myListBox.Bind(wx.EVT_LISTBOX, self OnEVT_LISTBOX)

Then you add:

  def OnEVT_LISTBOX(self, event):
       if event.GetSelection() == non-selectable: # the int index of the

forbidden item
myListBox.SetSelection(self.FormerSelection)

       else:
           self.FormerSelection = event.GetSelection()
           event.Skip()
