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 );

use the ui class of your main-window to get the icon action and uncheck it, eg.

ui->actionDraw_Polygon->setChecked(false);
