wxPython Vertical Scroll for Notebook Tab

Question

I am trying to add a vertical scroll bar to one of my notebook tabs using wxPython. I have tried adding the window style wx.VSCROLL to a few different panels and I am not getting any luck. Here is my code:

import wx
import os
class MyFrame(wx.Frame):
    def __init__(self, parent, ID, title):
        wx.Frame.__init__(self, parent, ID, title=title, size=(500,200))

        main = wx.Panel(self)

        nb = wx.Notebook(main)

        loginPg = wx.Panel(nb)
        entryPg = wx.Panel(nb, style=wx.VSCROLL) //<--- This kind of works
        projectsPg = wx.Panel(nb)

        nb.AddPage(loginPg, "Login")
        nb.AddPage(entryPg, "Entry")
        nb.AddPage(projectsPg, "Projects")

        self.entTitle = titlePanel(entryPg, -1)
        self.entLabel = labelPanel(entryPg, -1)
        self.entDescription = descrPanel(entryPg, -1)

        mainSizer = wx.BoxSizer(wx.VERTICAL)
        entryPgBox = wx.BoxSizer(wx.VERTICAL)

        mainSizer.Add(nb, 1, wx.ALL|wx.EXPAND)

        entryPgBox.Add(self.entTitle, 0, wx.EXPAND)
        entryPgBox.Add(self.entLabel, 0, wx.EXPAND)
        entryPgBox.Add(self.entDescription, 0, wx.EXPAND)

        entryPg.SetAutoLayout(True)
        entryPg.SetSizer(entryPgBox)
        entryPgBox.Fit(entryPg)

        main.SetAutoLayout(True)
        main.SetSizer(mainSizer)
        mainSizer.Fit(main)
        self.Layout()
        self.Show()

app = wx.App(False)
frame = MyFrame(None, -1, 'Test')
frame.Show()
app.MainLoop()

My goal is to have the second tab "Entry" of my notebook vertically scrollable. By adding style=wx.VSCROLL to entryPg I get a scrollbar for that tab but it will not scroll down. How do I get my Notebook Tab entryPg to have a vertical scrollbar that will scroll down? Any help is greatly appreciated!

Use a wx.ScrolledWindow instead of a wx.Panel to get a vertical scroll bar.

Here's a minimal example:

import wx

class Frame ( wx.Frame ):

    def __init__( self, parent ):
        wx.Frame.__init__ ( self, parent, id = wx.ID_ANY, title = u"Test", pos = wx.DefaultPosition, size = wx.Size( 600,300 ), style = wx.DEFAULT_FRAME_STYLE|wx.TAB_TRAVERSAL )

        self.SetSizeHintsSz( wx.DefaultSize, wx.DefaultSize )

        sizer = wx.BoxSizer( wx.VERTICAL )

        self.notebook = wx.Notebook( self, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, 0 )
        self.login = wx.Panel( self.notebook, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.TAB_TRAVERSAL )
        self.notebook.AddPage( self.login, u"Login", False )
        self.entry = wx.ScrolledWindow( self.notebook, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.HSCROLL|wx.VSCROLL )
        self.entry.SetScrollRate( 5, 5 )
        entry_sizer = wx.BoxSizer( wx.VERTICAL )

        self.text = wx.StaticText( self.entry, wx.ID_ANY, u"Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim.

Maecenas nec odio et ante tincidunt tempus. Donec vitae sapien ut libero venenatis faucibus. Nullam quis ante. Etiam sit amet orci eget eros faucibus tincidunt. Duis leo. Sed fringilla mauris sit amet nibh. Donec sodales sagittis magna. Sed consequat, leo eget bibendum sodales, augue velit cursus nunc,", wx.DefaultPosition, wx.DefaultSize, 0 )
        self.text.Wrap( 600 )
        entry_sizer.Add( self.text, 1, wx.ALL, 0 )


        self.entry.SetSizer( entry_sizer )
        self.entry.Layout()
        entry_sizer.Fit( self.entry )
        self.notebook.AddPage( self.entry, u"Entry", True )

        sizer.Add( self.notebook, 1, wx.EXPAND |wx.ALL, 0 )


        self.SetSizer( sizer )
        self.Layout()

        self.Centre( wx.BOTH )
        self.Show()

if __name__ == "__main__":
    app = wx.App()
    Frame(None)
    app.MainLoop()

Here the Entry page will have both a vertical and horizontal scroll bar. Note that the scrollbars will be active only if the contents of the widget overflows the currently displayed size. If you maximize this application window the sccrollbars will disappear.
