Detecting Window Focus

Is there a native way in Vizard to detect if a windowed application has focus? I am trying to prevent user input events from being passed through to other windows applications, and I would like to have a method to tell the computer to stop listening to the input device when the Vizard window doesn't have focus.

You can use the win32gui.GetForegroundWindow function to get a handle to the active window. You can check this handle against the Vizard window handle to determine whether Vizard has focus:

Code:

import win32gui



def VizardHasFocus():

        return win32gui.GetForegroundWindow() == viz.window.getHandle()



if VizardHasFocus():

        print 'Vizard has focus'

else:

        print 'Vizard does not have focus'
