make QLabel clickable using PyQt5

Question

I have a Qlabel filled with QPixmap and I want to start a process/function once this label clicked. I had extended QLabel class as follows:

from PyQt5.QtCore         


        

Answer 1

class ClickableLabel(QtWidgets.QLabel):
    def __init__(self, whenClicked, parent=None):
        QtWidgets.QLabel.__init__(self, parent)
        self._whenClicked = whenClicked

    def mouseReleaseEvent(self, event):
        self._whenClicked(event)

and then:

        my_label = ClickableLabel(self.my_label_clicked)
...
    def my_label_clicked(self, event):
        button = event.button()
        modifiers = event.modifiers()

        if modifiers == Qt.NoModifier and button == Qt.LeftButton:
            logger.debug('my_label_clicked: hooray!')
            return

        LOGGER.debug('my_label_clicked: unhandled %r', event)
