Regarding events and creating new classes: you can use event filters in classes that need to react to them.

"Yes, you can use events BUT !!! you have create new class for each widget with custom event. This is huge efficiency lost;" - NOT EXACTLY. I just end up with bool eventFilter that handles several widgets and then installEventFilter(this) on all the child widgets. And this isn't losing efficiency and programming performance! Actually I Never use "Promoted widgets"... I drop just plain empty widget, install this as eventFilter on it and reimplement most of my events within my main cpp class. Try it, didn't pain :) You can customize almost EVERYTHING in Qt without creating new classes everytime
