QActionGroup::checkedAction() question
Message 1 in thread
Hello,
I am playing around a bit with Qt-4.3 and QActionGroup. That is,
dynamically adding and removing actions from a group. My observation
is that groups remember checked actions even if it they are removed from
a group. I wonder if this is intentional?
I Hope some lines of Python code are not inappropriate here:
import sys
from PyQt4 import QtGui, QtGui
app = QtGui.QApplication(sys.argv)
group = QtGui.QActionGroup(None)
action = QtGui.QAction('test', group)
group.addAction(action)
action.setCheckable(True)
print group.checkedAction() is None
#>> True
action.setChecked(True)
group.removeAction(action)
print group.checkedAction() is action
#>> True

Looks like a bug - A quick look at the code suggests that
QActionGroup::removeAction does not clear d->current. Can you please
report this bug to qt-bugs@xxxxxxxxxxxxx so we can look into this further?
Thanks,
