python - PyQt QWebPage linkClicked 信号可以检测使用了哪个鼠标按钮

Question

我目前正在将此信号与处理点击的函数连接起来。例如:

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

def navigate(self, url):
    #do something

我想要的是导航功能知道是否通过鼠标左键或右键单击了链接。类似的东西

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

这可能吗？

另一种方法是重新实现 mousePressEvent 并在那里过滤鼠标事件:

#!/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_())
