How do I hide the window title bar from QDockWidget

@mrjj said in How do I hide the window title bar from QTabWidget:

I just wonder where that space comes from as the examples don't have it.

That must be the layout default margins...The OP mentioned using a vertical layout...

@Bonnie
Also my thought but we did try
setContentsMargins(0,0,0,0);
higher up.

So maybe that space is really just the hidden titlebar, it just look bigger to me than the samples.

I would guess that the OP call that on the widget, not the layout...
Ah...maybe not...
I'm not sure what's the current situation now. I thought the gap in the later picture would be that titlebar?

Ok so thats as far as we can come as you cannot move tabWidget more up. :)

@mrjj is there any way to use Qt::FramelessWindowHint and giving resizeability to the widget at the same time. Because whenweused the Qt::FramelessWindowHint, widget is not able to be resizeable anymore ?

Hi
Sadly not. That flag removes the decorations. ( the frame) and those are used by the OS to resize.
It's possible to hand code it but it's hard work.
Often people use less code-intensive solution and allow resize from right, bottom corner only.

Hi
There is also
https://github.com/dfct/TrueFramelessWindow
which supports most features like resizing and dragging

I want to hide the default "window title" bar that's on top of the dockwidget.

@lansing, stackoverflow.com/revisions/21701604/1 should work:

dockWidget->setTitleBarWidget(new QWidget());

Otherwise, maybe follow stackoverflow.com/q/18918496.
