I want to implement mechanism similar to the one used in GMail
attachments, where by unchecking check box you remove an attachment
from the mail. I have created following piece of code, which should
remove options when they are unchecked, but unfortunately I receive
warnings when I set parent to None. Can you make it right somehow? Do
I have to keep some separate set of unchecked boxes and delete them
from time to time? That wouldn't be very elegant - I prefer to remove
them at the moment, when user wants them removed. Could anyone suggest
me something?
class QChoices(QWidget):
def __init__(self):
QWidget.__init__(self)
self.setLayout(QVBoxLayout())
def addChoice(self, choice):
checkBox = QCheckBox(choice)
checkBox.setCheckState(Qt.Checked)
self.connect(checkBox, SIGNAL('stateChanged(int)'),
self.remove)
self.layout().addWidget(checkBox)
def remove(self, state):
if state != Qt.Unchecked:
raise Exception('Choice checked back again!')
self.sender().hide()
self.sender().setParent(None)
self.updateGeometry()
