QPushButton clicked

[d_stranz]

So the main purpose of it is how to serve a lot of buttons.

It sounds like you are asking for a slot to be called any time a button is clicked, whether you connect to its signal or not. How would that even be possible? How could the poor button know which of the slots in your app to call if you don't tell it?

If you don't connect -some- slot to -every- button's clicked() signal, your slots will only be called for the buttons where you did make a connection.

If you make a single slot and connect it to all of the buttons' clicked() signals, you can use the QObject::sender() method inside the slot to give you the pointer to the button instance that invoked the slot, and you can use that pointer to find out the button's properties (like name).

Edit: high_flyer's QSignalMapper might also work, but it is a bit hard to understand for a beginner.

For the setup you can just retrieve all buttons or all buttons within a widget using QObject::findChildren().

Then loop over the list to connect to the slot or signal mapper.

Thanks!
d_stranz - you are right. I thought that exist a event that is called any time a button is clicked and then in that event/function I get clicked button property (e.g. accessibleName) and accordingly to it I do sth.
So, I'll try QObject::findChildre() to connect to the slot and QObject::sender() to get the clicked button.

There is no "click" event because these are in fact multiple events in a certain order, i.e. a mouse press event followed by a mouse release event within a button's geometry.

If there were an event you could install a global event filter but that would also be way more hackish than dealing with the buttons explicitly.
