Answer 1

You have several typos in your code. Here's a corrected example:

from Frame2 import fr
def OnButton4Button(self, event):
    fr.Show()
    event.Skip()  # you need to spell event correctly

This assumes that Frame2 is a module. Most of the time, you don't need to use globals in Python.

To make this a bit easier to follow, I wrote an example that has a MainFrame class and a Frame2 class in the same module so you don't have to import anything or use globals:

import wx

########################################################################
class Frame2(wx.Frame):
    """"""

    #----------------------------------------------------------------------
    def __init__(self):
        """Constructor"""
        wx.Frame.__init__(self, None, title="Frame2")
        panel = wx.Panel(self)



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

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

        button = wx.Button(panel, label="Open Frame2")
        button.Bind(wx.EVT_BUTTON, self.onButton)
        self.Show()

    #----------------------------------------------------------------------
    def onButton(self, event):
        """"""
        frame = Frame2()
        frame.Show()
        event.Skip()

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