[PySide] uncheck button after drag&drop

[Aaron Richiger]

Hello Frank and Sebastian!

You are both right... Because you are discussing about different code, I 
guess. The tutorial indicated by Frank does not work on Mac for me 
(maybe, I am just to stupid to figure out how to trigger a 
RightMouseButtonEvent on Mac, but anyways), so I guess, Sebastian tried 
the code of the tutorial on Windows, where right clicks perfectly work, 
but they do not leave down the original button.
Then I guess, Frank changed the tutorial code slightly to drag and drop 
with left clicks on MacOS. And there it is, the original button stays 
down after dragging and I think, this behaviour is platform independent, 
so Sebastian would get the same problem I guess...
But it's not a bug of PySide or Qt, but just the normal behaviour of 
buttons, if you click them with the left mousebutton. They are looking 
"down", to repair this, simply call self.setDown(False) in the 
mouseMoveEvent() method. You get a changed version of the tutorial (not 
only dragNdrop, but also creating a new widget as Frank wanted) here:

Play around dragging the buttons with the left mouse button and 
uncomment the self.setDown() call to see Franks issue platform independent.

Lot's of "guesses" and "maybes", but could be the solution...
Aaron
