使用pyqt4在python中的QLabel上的可点击事件？

Question

我正在python GUI中使用pyqt4库和新的信号和插槽.我不知道如何将事件放在标签名称上QPLabel.这是我的代码:

class Ui_Form(object):
    def setupUi(self, Form):
        Form.setObjectName(_fromUtf8("Form"))
        Form.resize(759, 598)
        font = QtGui.QFont()
        font.setPointSize(12)
        ...
        ...
        ...
        self.QPLabel = QtGui.QLabel(Form)
        self.QPLabel.setGeometry(QtCore.QRect(620, 420, 141, 20))
        QtCore.QObject.connect(self.QPLabel, QtCore.SIGNAL(_fromUtf8("clicked()")), self.doSomething)
    def doSomething(self):
         print 'Label click'

任何人我应该为标签上的事件做些什么来做一些动作.

Answer 1

更新以下行:

QtCore.QObject.connect(self.QPLabel, QtCore.SIGNAL(_fromUtf8("clicked()")), self.doSomething)

至:

self.QPLabel.mousePressEvent = self.doSomething

并将event参数添加到doSomthing

...
def doSomething(self, event):
...
