Improvement of tool button in KDE4

[Miroslav Bendik]

Hello,

I'm sending my improved version of QToolButton with menu. In case of standard 
QToolButton, it is necessary to hold a left clik for 600ms until the menu 
will show up. In my implementation, it is possible to show the menu 
immediately by simple click&drag. After the action, the menu will appear 
immediately. Menu actions are launched by left mouse button release over the 
menu item. It is also possible to launch standard action like folder up in 
case of up button in konqueror.

I'm aware that my implementation is not very user firendly. But on the other 
hand, it has some advantages ( 
http://mireq.linuxos.sk/kde4/toolbar_buttons.png ) too. I would be really 
happy if it was implemented. As we can find 2 types of such buttons in KDE4. 
In my opinion, KDE4 should have one global settings for all buttons in 
applications (SystemSettings / Apperance / Style / Fine Tunning / Toolbar 
button type (buttons with special arrow / small buttons)).

The source code of my implementation can be found at
