Managing two frames

wxPython Users
1

Check out the code below.

It creates MyFrame the first time through. When the "close me" button is
selected, then MyFrame posts a "MyEvent" to the app, which closes MyFrame
and creates/shows MyFrame2.

The code is pretty simple to follow.

HTH,

# begin code

from wxPython.wx import *

# First create an ID for your custom event
EVT_MYEVENT_ID = wxNewEventType()

# Next, provide a "hook" for your event (not sure of the proper name)
def EVT_MYEVENT(win, func):
    win.Connect(-1, -1, EVT_MYEVENT_ID, func)

# Finally, create the actual event object.
class MyEvent( wxPyCommandEvent ):
    def __init__(self, id):
        wxPyCommandEvent.__init__( self, EVT_MYEVENT_ID, id )

# Now two separate frames. The first one below will fire the custom
# event
class MyFrame( wxFrame ):
    def __init__( self ):
        wxFrame.__init__( self, None, -1, "Test" )
        self.SetSize( wxSize( 240, 240 ) )
        self.SetBackgroundColour( wxRED )

        btn = wxButton( self, 1212, "Close me" )

        EVT_BUTTON( self, 1212, self.on_close_me )
        self.Centre()

    def on_close_me( self, e ):
        # Close the window, and post our custom event
        self.Close( true )
        evt = MyEvent( self.GetId() )
        app = wxGetApp()
        app.ProcessEvent( evt )

class MyFrame2( wxFrame ):
    def __init__( self ):
        wxFrame.__init__( self, None, -1, "Test Frame two" )
        self.SetSize( wxSize( 240, 240 ) )
        self.Centre()

class MyApp( wxApp ):
    def OnInit( self ):
        self.frame = MyFrame()
        self.frame.Show( true )

        # Handle our custom event
        EVT_MYEVENT( self, self.on_my_event )
        
        return true

    # Define the event handler for our custom event
    def on_my_event( self, evt ):
        self.frame.Close()

        self.frame = MyFrame2()
        self.frame.Show( true )
        
def main():
    app = MyApp(0)
    app.MainLoop()

if __name__ == "__main__":
    main()

I need to input three lines of text, with two bing passwords that are
***'d over (which that I can do now).

"If you have to use a wxFrame, you'll have to define a new event and
post it back to the app and handle it from the event handler"

Ok how do I do that.
