Question

I’ve got a Python script nearly identical to that on the wxPy Wiki, and I’d like to run a function in (no indentation) every time the tab is changed. I’ve tried just putting theFunction() after the wx.Frame.__init__... line in the def __init__ in each of hte three classes used by the Notebook. When I do this, the window closes immediately after closing, with no error in the terminal. What am I doing wrong? Here’s what I have for each class used by the notebook:

class Textures(wx.Panel):
    def __init__(self, parent):
        wx.Panel.__init__(self, parent)
        self.textureslist = wx.ListBox(choices = ['One', 'Two', 'Three'], id = -1, name = 'textureslist', parent = self, pos = (6, 0), size = (382, 150))
        getDivVars()

EDIT: The reason it was quitting was related to accidentally using App, not PySimpleApp. However, the list still doesn’t update (which getDivVars() does) each time the tab is changed. I still need to do this.

Answer 1

To have a function called whenever the notebook page changes, bind the EVT_NOTEBOOK_PAGE_CHANGED event to a function or method. Taking the ‘Simple wx.Notebook Example` as a starting point, you’d add a line

    nb.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, self.some_method)

or, if you want to call a function outside of a class instead of a method,

    nb.Bind(wx.EVT_NOTEBOOK_PAGE_CHANGED, some_function)

some_function would need to take a single parameter, and some_method would need to take a single parameter in addition to self.
