[PyKDE] Is QObject.sender() working ?

[Yves BAILLY]

Hi all,

Sorry if this as already been reported.

Look at this little code :
class MyWidget(qt.QWidget):
    def __init__ (self, *args):
        apply (qt.QWidget.__init__, (self,)+args)
        self.vbox = qt.QVBoxLayout(self)
        # Create two buttons
        self.bt1 = qt.QPushButton("Button 1", self) ;
        self.bt2 = qt.QPushButton("Button 2", self) ;
        # Print button references
        print "Button 1:", self.bt1
        print "Button 2:", self.bt2
        # Add them in the layout
        self.vbox.addWidget(self.bt1)
        self.vbox.addWidget(self.bt2)
        # Connect both buttons to the same slot
        self.connect(self.bt1, qt.SIGNAL("clicked()"), self.Clicked)
        self.connect(self.bt2, qt.SIGNAL("clicked()"), self.Clicked)
        
    def Clicked(self):
	obj = self.sender()
        print "-- Button clicked:", self.sender()
            
And here's a sample output, where I clicked both buttons :
[yves at kafka ConfiMake]$ ./test.py
Button 1: <qt.QPushButton instance at 0x82eb92c>
Button 2: <qt.QPushButton instance at 0x82efbcc>
-- Button clicked: None
-- Button clicked: None

So : the QObject.sender() function seems to return always "None".

Then I did the very same program in C++ (pure Qt), clicking also on
both buttons, and this is the output :

[yves at kafka ConfiMake]$ ./test.x
Button 1: 0x8088120
Button 2: 0x8088358
-- Button clicked: 0x8088120
-- Button clicked: 0x8088358

This time, QObject::sender() works fine...

Is this a bug in PyQt ? If not, how can I find the sender of a signal ?
Please help.

Best regards,
