Hello all!
I was wondering why there are so few slots connected to widgets.
For example the pushbutton has on_released, on_clicked, on_pressed etc, but it's missing so many slots (that I personally don't use but...) like on_mouse_over, while_is_clicked etc...
This came to my mind while trying to create a small program that while you have pressed a button, the value of a slider changes and when you release the pushbutton then the slider stops. So, I searched for a slot something like while_it_is_clicked() but there wasn't any, and, finally I created a QTimer that was starting at pressed() and stopped at released().

So, the conclusion maybe, is that there aren't these slots because are easily developed by the user, using the already existing?
