关于python：可以使用PyQt QWebPage linkClicked信号检测使用了哪个鼠标按钮

Can PyQt QWebPage linkClicked signal detect which mouse button was used

我正在将此信号与处理单击的函数连接。例如：

1
2
3
4

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

def navigate(self, url):
#do something

我想让导航功能知道链接是用鼠标左键还是右键单击的。有点像

1
2
3
4
5

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

号

这有可能吗？

另一种方法是重新实现mousePressEvent并过滤鼠标事件：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22
23
24
25
26
27
28
29
