[PATCH] Show the clipboard history when pressing the Paste button

Hi,

  Here is an implementation of Datschge's idea: provide a list of the 
clipboard history under the Paste button (similar to the history in 
Konqueror). This is a generic implementation and by applying the patch every 
application will benefit of it without any change. It creates a new action 
class (KPasteAction) which communicates with Klipper via dcop. Of course 
there is no guarantee that Klipper is running, in that case the button works 
like before, and the only item in the menu is the current clipboard content. 
So the patch contains the KPasteAction class (the code could be simplified in 
KDE 4.0 if we inherit from KToolBarPopupAction and make the popupMenu() 
method virtual) and a change in the KStdAction, so for Paste this class will 
be used. 
 I have only one problem with it that I couldn't solve cleanly: when a menu 
item is selected, I change the clipboard with a DCOP call, but the clipboard 
isn't changed immediately (see the debug output) and I have to use a 
singleShot timer to send the "activated" signal. Otherwise the selected text 
won't be pasted. I'm afraid a little about this issue as there may still be 
cases when the timer is elapsed before the clipboard is set. Any better ideas 
here? Setting the clipboard directly does not work and I get 
"QClipboard::setData: Cannot set X11 selection owner for CLIPBOARD" in the 
debug output.

Andras
