Grab qcomboxbox index

[likage]

I have a QComboBox in which it contains 2 items.

How can I code it in such a way that when the first item in the combobox is selected, it will call out the function that is for the first item. Likewise, if the second item is selected, it will call out the function for the second item, something similar like using list index [0], [1] etc..

self.methodCombo = QComboBox()
self.methodCombo.addItem('method01')
self.methodCombo.addItem('method02')

Have look at the currentIndexChanged signal.

There are a couple ways to do this. One is to store your callbacks as the data for each item:

class Test(QtGui.QDialog):

    def __init__(self):
        super(Test, self).__init__()

        self.combo = QtGui.QComboBox()
        self.combo.addItem("First Callback", self.callback1)
        self.combo.addItem("Second Callback", self.callback2)

        self.combo.activated.connect(self._comboActivated)

        layout = QtGui.QVBoxLayout(self)
        layout.addWidget(self.combo)

    def callback1(self):
        print "callback1"

    def callback2(self):
        print "callback2"

    def _comboActivated(self, idx):
        fn = self.combo.itemData(idx)
        fn()

That's pretty neat. I would have used a whole lot more code. Thanks for the tip, Justin.
