QT - uncheck check box

Question

Guys please let me know how to uncheck the check box using QT C++.

Answer 1

You can use the setChecked() method from QAbstractButton.

QCheckButton b;
b.setChecked( false ); // Uncheck it

Alternatively you could use setCheckState() setCheckState() method from QCheckButton. This gives you the option to 'partially uncheck' it.

QCheckButton b;
b.setCheckState( Qt::Unchecked );
