How to track for each button its clamping and releasing?

Question

PyQt

Each button is a separate class in which a QPushButton is created. For each object, you need to track the clamping and releasing of the widget itself or the mouse button. How to implement it?

Answer 1

Well, yes. Certainly. First you should have asked, and then looked at the documentation ...
If someone needs it:

# Сигналы зажатия кнопки.
self.button.pressed.connect(self.pressed_)
# Сигналы отпускания кнопки.
self.button.released.connect(self.release_)

Answer 2

Catch the mousePressEvent(QMouseEvent *event) and mouseReleaseEvent(QMouseEvent *event) events of the QWidget descendant , which is QPushButton
