Active and Inactive Windows

[arunarora]

Hi,

I am writing a Linux app which involves a functionality to detect active and inactive windows. For that is there a C/C++ code which could be used for detect the active and inactive windows in Linux OS. I want a solution which could be used in any Linux distro, or, maybe, on the most widely used distributions atleast.

Also, as far as I assume KDE and GNOME being different Window Managers should have different mechanisms/APIs to get the Active and Inactive windows status. So I do not want to use those APIs as user could work in any of these.
Please correct me if I am wrong.

I really appreciate any help.

Thanks,
Arun

Hi,

there was some effort going on to create a common base protocol for window management. I know Metacity (GNOME) and some KDE WMs obey it.
