QWidget with QTabWidget

[mpergand]

@ixion
Try:
tableWidget->resize(500,400);
If it doesn't work try to set a fixed or a minimum size instead.

thanks, I know about resize, I'm interested in the automatic resizing of the widget, without explicitly specifying the size

@ixion without being in a layout, as far as I know, there's nothing. I think you will have either to live with your main widget not risizing automatically, or implement that auto resize by yourself (by adding the width of all tabs + some constant should be what you need).

@ixion
I don't think it works with a tabWidget ...
What size is return by tabWidget->sizeHint() ?

[ixion]

@mpergand QSize(204, 32)

Seems close to the image you post.
In the Designer try with different size policies and see if it changes something.

Actually, the default behaviour is not the same between MacOs and Linux !

I have only used Qt on Linux. My impression was that it never auto-grows a top-level window, at least when you put more content into it, i.e. like the left-hand one. Maybe it only does that window-widening under MacOS?

Since on linux, the length of the tab titles are not taken into account, the overall size of the tab widget reflects the widest element present in the tab pages.

On mac, the minimum size of the tab widget depends of the length of the tab titles.
Otherwise the tab titles are troncated with ellipsis, very ugly.
