How to make a wxFrame behave like a modal wxDialog object

Question

Is is possible to make a wxFrame object behave like a modal dialog box in that the window creating the wxFrame object stops execution until the wxFrame object exits?

This took me an annoying amount of time to figure out but here is a working example that grew out of Anurag's example:

import wx

class ChildFrame(wx.Frame):
    ''' ChildFrame launched from MainFrame '''
    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, -1,
                          title=self.__class__.__name__,
                          size=(300,150))

        panel = wx.Panel(self, -1)
        closeButton = wx.Button(panel, label="Close Me")

        self.Bind(wx.EVT_BUTTON, self.__onClose, id=closeButton.GetId())
        self.Bind(wx.EVT_CLOSE, self.__onClose) # (Allows frame's title-bar close to work)

        self.CenterOnParent()
        self.GetParent().Enable(False)
        self.Show(True)

        self.__eventLoop = wx.EventLoop()
        self.__eventLoop.Run()

    def __onClose(self, event):
        self.GetParent().Enable(True)
        self.__eventLoop.Exit()
        self.Destroy()

class MainFrame(wx.Frame):
    ''' Launches ChildFrame when button is clicked. '''
    def __init__(self, parent, id):
        wx.Frame.__init__(self, parent, id,
                          title=self.__class__.__name__,
                          size=(400, 300))

        panel = wx.Panel(self, -1)
        launchButton = wx.Button(panel, label="launch modal window")

        self.Bind(wx.EVT_BUTTON, self.__onClick, id=launchButton.GetId())

        self.Centre()
        self.Show(True)

    def __onClick(self, event):
        dialog = ChildFrame(self, -1)
        print "I am printed by MainFrame and get printed after ChildFrame is closed"

if __name__ == '__main__':
    app = wx.App()    
    frame = MainFrame(None, -1)
    frame.Show()
    app.MainLoop()
