Question

I’m currently connecting this signal with a function that handles the click. For example:

QtCore.QObject.connect(self.ui.webView, QtCore.SIGNAL("linkClicked (const QUrl&)"), self.navigate)

def navigate(self, url):
    #do something

What I’d like to is for the for the navigate function to know if the link was clicked on by the left or right mouse button. Something like

def navigate(self, url, event):
    if event == Qt.LeftClick:
        #do something
    if event == Qt.MidClick:
        #do something else

Is this possible?

Another method is reimplementing the mousePressEvent and filtering mouse events there:

#!/usr/bin/env python
#-*- coding:utf-8 -*-

from PyQt4 import QtCore, QtGui

class myWindow(QtGui.QWidget):
    def __init__(self, parent=None):
        super(myWindow, self).__init__(parent)

        self.label = QtGui.QLabel(self)
        self.label.setText("Click Me")

        self.layout = QtGui.QHBoxLayout(self)
        self.layout.addWidget(self.label)


    def mousePressEvent(self, event):
        if event.buttons() == QtCore.Qt.LeftButton:
            self.label.setText("Left Mouse Click!")

        elif event.buttons() == QtCore.Qt.RightButton:
            self.label.setText("Right Mouse Click!")

        return super(myWindow, self).mousePressEvent(event)

if __name__ == "__main__":
    import sys

    app = QtGui.QApplication(sys.argv)
    app.setApplicationName('myWindow')

    main = myWindow()
    main.resize(150, 150)
    main.show()

    sys.exit(app.exec_())
