Passing values to custom 'slot' functions (pyqt)

[Richie]

Hi,

Can I first say thanks to all who read my newb questions and helped me out, much appreciated.

Quick pyqt question:

mywindow has a button on it. I want to run the clicked_function when clicked. This works

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), clicked_function)

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), clicked_function)

To copy to clipboard, switch view to plain text mode 

But if I want to click the button and pass 'foo' to the clicked_function, I thought I would be able to use

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), clicked_function('foo'))

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), clicked_function('foo'))

To copy to clipboard, switch view to plain text mode 

This brings up an 'argument of incorrect type' error. So how can I pass a value to the function? I thought I might try...

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), pre_clicked_function)
 
def pre_clicked_function():
    clicked_function('foo')

QtCore.QObject.connect(mywindow.somebutton, QtCore.SIGNAL("clicked()"), pre_clicked_function)

def pre_clicked_function():
    clicked_function('foo')

To copy to clipboard, switch view to plain text mode 

But this is far from streamlined! Any better ideas?
