I'm currently developing a win32::GUI based application where I want to track window events. I want to know which is the active window at any time.

The code for this is the following
Win32::GUI::GetForegroundWindow();

What I want is to save the value it returns when it changes. For the time being, I'm using the following bit of code :
while(1)
{
   $activeWindow=Win32::GUI::GetForegroundWindow();
}
The best thing would be to write a listener that'd be triggered when there's an active window changed. Does anyone have an idea ? Thanks guys.
