Can Tk be connect with Copyboard of Linux

[Xiao-Qin Xia]

Hi, everybody,

Under windows, the copyboard is shared by all the applications. So I can 
copy some messages from different applications, and paste them into a Text 
or Entry widgit based on Tkinter/Tk. But I found the same operation cannot 
work under linux. Under KDE, I can not paste messages from other 
applications into a widget based on Tkinter/Tk. Is it possible to solve 
this problem?

Cheers,
Xiao-Qin
