QMenu Multiple selection problem

Hi all Experts,
I am developing an application in which i am using QMenu.
I have added QActions into the menu , which are checkable.
My requirement is that
1) I should check multiple actions when the menu gets displayed (without vanishing the menu).
2) when i click ouside of the menu the menu should get vanished.

I have attached the images which will make you understand more about my requirement.

I want to deselect first three actions without the menu getting vanished.

after clicking on needed action use removeAction for menu which holds this action.

QMenu works like menus are supposed to work. Are you sure you want to break commonly accepted UI design principles with such a weird construct? That would not be a menu any more but more like a custom popup component.

Example Code

void Widget::customContextMenuRequested(const QPoint &pt)
{
menu->popup(mapToGlobal(pt));
}

void Widget::actionsTriggered(QAction *actionPassed)
{
menu->show();
}

will give you multiple selection QMenu
