ogg

Im tring to create an mp3 player with ogg ( works great ) im also using wxPython module to add an interface on it.. but i have one question. How do i stop the audio from playing once the user hits the x button on your top right hand corner of the program? does wxWindow have a function for this? is there a tutorial for ogg that better explains more about it?

I do not know anything about the ogg API, but I presume there is a function to stop the audio. So the problem is how to call this function when the user exits your program. There are basically two ways to do this in wxPython:

1) You can associate a function with the close event of the main Frame, using EVT_CLOSE.

2_ Alternatively you could override the OnExit method of the class you derive from wxApp, to do the cleanup when the application exits.

I think the first option is preferable. If you trap the close event then you must call the Frame's Destroy method to actually close the window.

Here is a simple example:

Code:

#!/usr/bin/env python

import wx

class Frame(wx.Frame):
    def __init__(self, parent=None, id=-1,
                 pos=wx.DefaultPosition, title='Close Me'):
        wx.Frame.__init__(self, parent, id, title, pos)
        wx.EVT_CLOSE(self, self.onClose)
        
    def onClose(self, event):
        '''called when the Frame is closed by whatever means'''
        wx.MessageBox('Bye Bye', 'Closing')
        self.Destroy()

class App(wx.App):
    def OnInit(self):
        self.frame = Frame()
        self.frame.Show()
        self.SetTopWindow(self.frame)
        return True

def main():
    app = App()
    app.MainLoop()

if __name__ == '__main__':
    main()

This will pop up a message box when the Frame is closed, either through clicking on the X or pressing Alt-F4 (on Windows).
