How to use QWigdetAction

Depositc29

I create a QWidgetAction and use addMenu to bind the submenu with it，but it can not show the submenu when I move my mouse on the QWidgetAction。I debug the source code found that it seems to fail to call the setCurrentAction function on the mouseMoveEvent，but if I use QAction, it work well。 So How should I solve this problem?

Hi and welcome to devnet,

Which version of Qt ?
On which OS ?
If Linux, which desktop environment ?
Please provide a minimal compilable example that shows the behaviour.

@SGaist
the platform is win10. Here is simple code.

QMenu*  topMenu = new QMenu;
QWidgetAction* pAct = new QWidgetAct;
QWidget* widget = new QWidget;
pAct->setDefaultWidget(widget);
QMenu* subMenu = new QMenu;
pAct->setMenu(subMenu);
topMenu->addMenu(subMenu);

when I move my mouse on the pAct, it can not show the submenu.

@Depositc29 please make it complete that way it ensures that we are all working with the same code.
