I'm working on a GUI program in which I already bind a start button with one event, and when I click the start button, the event runs as I like. My question is, if I want my program to start the event immediately after the GUI program starts, which means the start button is immediately being "clicked" once the program starts, how do I do it?
In the __init__( ) for your main frame put this:

wx.CallAfter( func_name )
How to make a event run immediately after a GUI program starts in wxpython?
