Hi,

By making some change in the above code i am able to find all the windows of 
my root window(by adding some "for" loops). Is there any particular class of 
windows or code for particular windows like Video players , Audio playes, 
Browsers etc.
In windows "Video" window, "Rendering" window etc has some particular class 
or code for them.


So is there similar class/code for Video, Audio, Browser window in 
Xlib/Xserver. If not how is it possible to identify that this particular 
window is for Video or Audio(other than "window name" comparison because 
this can change) .

If somebody can guide me regarding how to identify particlar windows it will 
be great help for me.
