Expanding/shrinking a widget

[punkypogo]

Hello,

In my app, I have a dockwigdet in which there is a (promoted) widget.
This widget has a more/less button : when I click on "more", the widget expands to show advanced options, and when I click on "less", the widget shrinks hiding the advanced options.

My problem is that when I click on "less", the dockwidget doesn't shrink at all, letting tons of space, which is ugly.

I saw this article (http://wiki.qtcentre.org/index.php?title=Expanding_dialog) on the wiki, but it doesn't work :(

Do you have an idea ?

Could you post some kind of minimal compilable test case for us to play with?

Hello,

Yes, I made you a complete compilable project.

Hmm, what's the point of using QDockWidget but no QMainWindow?

[punkypogo]

I know, it is not supposed to be used like that.

But I want it to be that way :D

edit : unless you have an idea to have the same behavior.

Hello,

Well, I followed your remark, jpn, and I tried to obtain what I want in a different way.

The main widget "Extension" has a promoted widget "Widget" in a gridlayout.
Widget can attach or detach itself from Extension thanks to the attach/detach button.

This approach is a bit better than the "fake" dockwidget one, but it's not perfect :
- Widget can attach or detach : OK
- Widget resizes well when attached in Extension, when the more/less button is activated : OK
- Widget does not resizes well when detached from Extension : FAIL.


My new project is attached.


Thanks in advance,
Cheers.

Hello,

Thanks to the Qt Support, I could achieve my goal.

Here are the new version of widget.h and widget.cpp, it could be useful to someone.
