How to add tooltip to (main) menu item ?

Anonymous_Banned275

The attached , under construction code , should add
BluetoothMenu_Terminal->setToolTip(text);
and it should show up when mouse is above / hovers above selected menu.

It does not.

It shows up when the main menu is selected / highlighted and mouse hovers over highlighted submenu.

Both main menu and its submenus should have its own tool tip.

Where is my code error ?

Any help would be appreciated.

{ // Jan3 add menu terminal
                    // Apr2 changed menu text
                    QMenu *BluetoothMenu_Terminal  = menuBar()->addMenu(tr("&Terminal ..."));
                    // tool tip shows up in submenu ???
                    text = " primary parent menu access to terminal and its  sub submenus ";
                    BluetoothMenu_Terminal->setToolTip(text);
                    
                    // primary parent menu access to  sub submenus

@AnneRanch UPDATE
Adding
BluetoothMenu_Terminal->setToolTipsVisible(true);

to main menu code (!)
makes submenu tool tips work correctly

I am not convinced if there is a way to make the tool tip work on main menu.
Hovering on main menu "pulls down " the submenus and that MAY be stopping / masking the main menu tool tip .

I can check that (theory / guess ) by having menu with NO SUBMENUS....

 QMenu *BluetoothMenu_Terminal  = menuBar()->addMenu(tr("&Terminal ..."));
                    // tool tip shows up in submenu ???
                    text = " primary parent menu access to terminal and its  sub submenus ";
                    BluetoothMenu_Terminal->setToolTip(text);
                    BluetoothMenu_Terminal->setToolTipsVisible(true);
