Setting a tool tip on the title bar of a dock widget

[Perdrix]

If I use QDockWidget::setTitleBarWidget(QLabel*) I can set a tool tip on that label that says e.g.:

Double click here to dock/undock the image list

If OTOH I don't set a title bar widget, how do I set a tooltip that applies just to the title bar of the dock widget?

Thanks

I fear you can not :(

void QDockWidget::setTitleBarWidget(QWidget *widget)

If a title bar widget is set, QDockWidget will not use native window decorations when it is floated.

(https://doc.qt.io/qt-6/qdockwidget.html#setTitleBarWidget)

Ergo, it will use the native OS title bar + decorations if no custom QWidget is used as one.
And I don't know of a way to set a QToolTip to some native OS controls.
For Windows it could be possible by using WinAPI
And you need different code for Linux/Mac then

Maybe helpful?!

Oh well it was worth asking - even if the answer's no.

Thank you
