Qt. I have a form. There is 2 widgets on it, that contains other widgets, buttons, line edits etc.
I need: When user sets focus, clicks by mouse, or does something with first widget or elements, that it contain – I need to set variable to 0. If he do something same with second widget – variable must be set in 1.
How to do that?
QApplication::focusWidget()returns pointer to widget which has focus at this moment. Also there isQApplication::focusChanged(QWidget *old, QWidget *now)signal and you can connect it to slot to change variable.
