pyqt: return pressed signal for spinbox?

Question

There are signals valueChanged() and editingFinished(), but I need perform my action only when key enter is pressed.

Is there any solution without reimplementing event handler?

I need to change focus to the next spinbox on pressed enter key. Any idea?

Answer 1

Use setKeyboardTracking(False)

If keyboard tracking is disabled, the spinbox doesn't emit the valueChanged() signal while typing. It emits the signal later, when the return key is pressed, when keyboard focus is lost, or when other spinbox functionality is used, e.g. pressing an arrow key.

You can access the underlying QLineEdit object which emits the desired returnPressed() signal:

spin_box = QSpinBox()   
spin_box.lineEdit().returnPressed.connect(self.spinBoxReturnPressed)

def spinBoxReturnPressed():
