Creating a custom layout for QWidget

[prajain]

How can I place widgets relatively to each other in a QWidget without using any layout widget (like QGridLayout, QLayout etc) in Qt?
Can i use grabWidget() and paint widgets to QWidget, using information from the QRect() of other widgets? If yes, how?

Why you don't want to use layouts?

Yes, of course you can do that, and you'll get a QWidget with pictures of other widgets in it. They aren't QWidgets, so your users won't be able to interact with them. Why on earth would you want to do something like that?

I suspect that you are not correctly designing your layouts, which is why you are trying to reinvent the wheel.

The reason is historical. Just tell me if you can do that. I want users to interact with the widgets.

Because I don't want to put my widgets in a grid-type manner. Can i do that?

You can postion all your widgets manually if you want. But that's usually a bad idea.

What manner do you want to put your widgets in then?

[prajain]

I wanted to put the widgets relative to other widgets. For example, I can place the widget either right or left and either top or bottom of a widget. Something like that.

You can do that with existing layouts or you can implement a custom layout to do this.

It sounds like you want something like "glue", which is used in another layout system the details of which I don't remember. "Interviews", maybe?

You can do this with grid, horizontal, vertical or a combination of layouts in a hierarchy. If you want to do this dynamically at runtime, then you need a way to specify the locations of widgets relative to each other, and build up the layouts to reflect that relationship. So if you have two widgets that are located top and bottom relative to each other, you create a a vertical layout, insert the top widget then the bottom widget.

If you don't want the widgets to expand their sizes or spacings as the container widget resizes, then insert horizontal or vertical spacers into the layouts.
