Win32::GuiTest Get Window Focus

PyrexKidd has asked for the wisdom of the Perl Monks concerning the following question:

How do I determine the window handle of the window that has focus, that is not a child of the Perl process? I thought this would work, but it returns 0 for all windows except the window generated by the perl process.

use 5.010001;
my $hwnd = GetDesktopWindow();
my $focus_id = GetFocus($hwnd);
say $focus_id;
[download]

Though I don't think it makes a difference, I am using Wx to generate a window and a timer event to poll the environment for the window with focus.

Thanks.

If you want to know the active window, have you tried Win32::GuiTest::GetActiveWindow(0)? This should be fairly equivalent to `GetFocus(0)`, but I haven't tried either.	[reply] [d/l]

A windows, which is not visible, cannot have focus -- you will have to minimize all other visible windows, minus any belonging to the taskbar -- there is an API call for that	[reply]

Duh, so the question wasn't about getting at the desktop ... `GetFocus( GetForegroundWindow() )` [download] works for me, but, Wx will give you hwnd if you use `$window->GetHandle()`. On a related note, see How to Retrieve another Process' Window Title?	[reply] [d/l] [select]

That's not entirely true. I've seen at least two poorly written programs, in which a modal dialog box ends up with the focus, but is behind another window. You can't move the obscuring window because the dialog has to be dealt with first, and you can't complete the dialog because the window is in the way...	[reply]
