As far as X is concerned, these windows are just pixels -- it doesn't 
keep track of the text.  This is done by the client applications.  
Copying and pasting is done by the application itself; when you use the 
Copy operation, the application sends a message to the X server telling 
it to put the text into the cut-buffer so that other applications can 
get at it.  But there's no way for one application to force another one 
to send it the contents of its window.
