clickable event on QLabel in python using pyqt4?

Question

I am working in python GUI using pyqt4 library and new with signal and slots. I don't know how to put event on label name QPLabel. Here is my code :

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' 

Anybody what should I do for event on label for doing some action.

Answer 1

Update the following line:

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

To:

self.QPLabel.mousePressEvent = self.doSomething 

and add the event parameter to doSomthing

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

Answer 2

QLabel doesn't have a signal clicked, so you can do one of the following:

A) Derive a custom class from QLabel implementing handlers for mouse events.

B) Implement the event handlers in Ui_Form, using standard QLabels and install the form as an event filter for the labels (self.QPLabel.installEventFilter (self)).
