Adding a shortcut to QAction inside QGraphicsScene context menu

Forfunckle

My QGraphicsScene subclass WorkspaceScene contains a variable for each action that it later uses inside the context menu. I have a function that sets up the actions and adds the shortcuts (which is called in the constructor of the class), and then I have a function that creates the context menu, which is called in the contextMenuEvent function I reimplemented.

Here's some relevant code:

// Constructor
WorkspaceScene::WorkspaceScene()
{
    _setUpActions();
}

// ContextMenuEvent
void WorkspaceScene::contextMenuEvent(QGraphicsSceneContextMenuEvent *event)
{
    _setUpItemMenu();
    _itemContextMenu.exec(event->screenPos());
}

void WorkspaceScene::_setUpActions()
{
    deleteAction = new QAction("Delete");
    deleteAction->setShortcut(QKeySequence::Delete); // This should add the shortcut
    connect(deleteAction, &QAction::triggered, this, &WorkspaceScene::deleteItemSlot);
}

void WorkspaceScene::_setUpItemMenu()
{
    _itemContextMenu.clear();
    _itemContextMenu.addAction(deleteAction);
}

This successfully sets up the actions and they work inside the context menu but the shortcut doesn't seem to work. What's the correct way of doing this?

In that case you need to also add the action to the widget.

Hi,

Do you mean you want the action to be triggered by the delete key when the menu is opened ? Or also the rest of the time ?

@SGaist I'd like the action to be triggerred at any point (even if the menu is not opened)
