Detailed Description
A check box is a checkable button that shows its state in an indicator next to the text. Connect to toggled():
QCheckBox *box = new QCheckBox("Remember me", window);
box->setChecked(true);
Check boxes: unchecked, checked, with the keyboard focus, and disabled.
See also QAbstractButton and QPushButton.
Differences from Qt
There are no tristate check boxes and no stateChanged() signal or checkState(); use toggled() and isChecked().
