Using QDockWidget in a QFrame

[Polnareff]

Hi,

I've noticed that the QDockWidget can only actually be docked within a MainWindow. I'd like to be able to have one which docks only within a QFrame. Is this possible, and why exactly does it have this behaviour?

A QMainWindow has the docking infrastructure, a QFrame does not.
So, no you can't use a QDockWidget in the same way in a QFrame as you do in a QMainWindow.

Why do you want dock widgets in a frame?

The problem lies in not being able to nest QMainWindows (assuming I'm not wrong about that). What I have is a mainwindow with different perspectives, switched via checkable toolbar buttons. The perspective change only alters everything below the toolbar, essentially loading almost an entire new part of the software. As a result, it's as if each of these perspectives is its own MainWindow, without its own toolbars. But since I can't just place a MainWindow within another, I use a QFrame.

This problem at hand is actually a bit more complicated, since I want my DockableWidget to reside in another QFrame nested in the one I spoke of above. Essentially, I have something resembling the following:



Everything below the toolbar is within a QFrame. And the right side of the treeview is actually another QFrame. As you can see, in that frame is where I want the QDockWidget to be.

You might need to do some clever hack for dock widget drag and drop.. you can extract the widget from QDockWidget and set it as a child of QFrame..
then on drag event, you can again set the widget as child of QDockWidget.....

it might not be easy,,, but thats what came to my mind

Ooohh...I like the idea. I'll give it a shot.

It still surprises me, though, that the library is like this. Has no one else ever wanted to use a QDockWidget in something nested within their QMainFrame?

Im curious about it! I've tried the same, but i found no "look and feel" solution to put the dockwidget back into the widget or in your case the frame. However, why didnt you nest your mainwindow into a widget and this widget into the mainwindow?

[Polnareff]

Can you nest a mainwindow? Cuz as far as I know, each time I try it just creates it as a new dialog. Otherwise I wouldn't have a problem. I guess I'll give it another shot...

I can't try it out atm, but I'm pretty shure. Maybe

setWindowFlags(Qt::Widget);

setWindowFlags(Qt::Widget);

will help?!

That worked! It was so simple :P Thanks a bunch!
