Question

I used the code below to dynamically create a group of radio buttons:

self.wPaymantType.qgbSomeSelectionGroup = QtGui.QGroupBox()
vbox = QtGui.QVBoxLayout()

for row in listOfChoices:
    radio = QtGui.QRadioButton(row)
    if bIsFirst:
        radio.setChecked(True)
        bIsFirst = False
    if len(row.name) > nMaxLen:
        nMaxLen = len(row.name)

    vbox.addWidget(radio)

self.wPaymantType.qgbSomeSelectionGroup.setLayout(vbox)

How can I iterate through all radio buttons to find out which one is checked?

I tried something like this, but I didn’t get anything good from it:

qvbl = self.qgbSomeSelectionGroup.children()[0]

for i in range(0, qvbl.count()):
    child = qvbl.itemAt(i)
    radio = QtGui.QRadioButton(child.widget())
    if radio != None:
        if radio.isChecked():
            print "radio button num " + str(i) + " is checked"

I believe the reason why it’s not working is your

 radio = QtGui.QRadioButton(child.widget())

call at the code where you’re checking if your checkbox is checked. I think what you’re trying to do is typecast the child object to QtGui.QRadioButton and it doesn’t work in this case. Instead you should be creating a new widget. Try changing it to smth. like this:

    qvbl = self.qgbSomeSelectionGroup.layout()
    for i in range(0, qvbl.count()):
        widget = qvbl.itemAt(i).widget() 
        if (widget!=0) and (type(widget) is QtGui.QRadioButton):
            if widget.isChecked():
                print "radio button num " + str(i) + " is checked"

the code above should be iterating through child objects of the layout object, check their type and print “radio button…” in case it’s radio buttong and it’s checked

hope this helps, regards
