I have a Tkinter program and running it like: python myWindow.py starts it all right, but the window is behind the terminal that I use to start it. 
Is there a way to make it grab the focus and be the foreground application? Does it depend on the platform?
This might be a feature of your particular window manager. One thing to try is for your app to call focus_force at startup, after all the widgets have been created.
Set focus on Tkinter window (depends on platform?)
