My showevent does not work properly.

[tonnot]

It works!
So, the trick is to wait some seconds or calling the slot ?
(The 'slot call' means a whole process or pending events?)

And, also can be a solution to process all events instead of using the singleshot?
I have try "QCoreApplication:rocessEvents" but it does not work
(I see the messagebox before the window)

Thank you very much.
