QDockWidget inside MDI area

Saviz

I have a requirement where I need to create multiple sub-windows inside the main window for different sections of my program.

I originally thought about using QDockWidgets because they accomplish this in a great way, allowing the user to drag and drop them into different sections and monitors. But, the only issue is that I cannot seem to place a dock in the central widget area of the main window. I tried hiding and placing dummy widgets inside the central widget (To stop it from displaying and taking up space in my program), but the results are not satisfying.

I did notice Qt offers a MDI area widget, but I cannot seem to place dock widgets inside of it.

Any solutions to my problem please?

Do it from your code, I don't think you should be trying to achieve this with Designer.

Did you try to set QMdiArea as your main window's central widget?

And then add your dock widgets to it as sub windows?

This is just a suggestion, I'm not sure I understand what you need, or if what I'm suggesting is correct, but give it a try.

Here's where I'm coming from: QMdiArea, QMdiArea::addSubWindow

@Abderrahmene_Rayene I will look into it and see if it works. Thank you for this suggestion. But, as far as I can remember in the designer I can only define what the layout of the central widget will be (I don't think I can replace the central widget with the MDI area)

Hi,

QDockWidget cannot go in the central area because they have defined area to be docked in.

You might want to check KDAB's KDDockWidgets.

@SGaist Thank you. I am already aware that dock widgets will not go in the area of the central widget. But, my question was is it possible to place them in a MDI area.

@Saviz not directly no, that's something you need to build on top of it.
