Dock widget does not have a size slider

[rakkar]

I placed a dock widget in my QTWidget window. It's on the right side of the window. However, there is no slider along the left border of the dock widget to adjust how wide it is. It is only a fixed size.

How can I force it to show the slider along the left border?

Maybe a QDockWidget is only resizeable in a QMainWindow (just tried it in Designer; fixed size in QDialog; resizeable in QMainWindow)?

Apart from that: I don't think the "slider" can be made visible. It is just there. The mouse cursor will change when it is over the "slider".

Maybe that's how it is then. I have one in a MainWindow as well, and it's slidable. But in this window it is not. Maybe someone can explain why this is.

Exactly. You have to use a QMainWindow.
