[SOLVED]QtabWidget, how to make it scrollable

andre

You don't make the tab widget scrollable, but instead you add a widget on the tab that provides the scrolling. Simply place a QScrollArea widget as your only widget on the tab, and place your form elements on that widget.

Better yet: design your forms in such a way that no scrolling is needed :)

ermm, i tried just that but it still doesn't show?

andre

Without showing us what you did, it is hard for us to see what you did wrong...

sharon_obl82

sorry, but here's a snapshot i took.

as you can see on the right, there are some widgets under the Scrollarea. I just kinda position the widgets under it and try to run it.
Am i missing something else?

Try putting everyting in proper layouts.

Looks like scrollbars policy is Qt::ScrollBarAlwaysOff (if container of your widgets is is QScrollArea).It should be Qt::ScrollBarAsNeeded (default) or Qt::ScrollBarAlwaysOn , so then you'll get desired result.

sharon_obl82

yes, the scrollbar policy is set to Qt::ScrollBarAsNeeded. I changed it to Qt::ScrollBarAlwaysOn but it's not scrollable :(

zeljko

strange, looks like controls parent isn't QScrollArea.
Have you tried same thing on QMainWindow (add QScrollArea + child controls) ?

sharon_obl82

Hi,
I tested with just adding QScrollArea and child controls on the QMainWindow but the scrollbar doesn't appear too when it's being run. :O

zeljko

Then I really don't know what's up.

Andre has a good suggestion.

Thanks guys, it was because of the layout problem. Btw, everytime i click "Layout in a Form layout" the scroll area automatically resizes to a small box on the top left corner. Is there a way to prevent this?

ChrisW67

Apply a layout at every level, including on the widget that contains the QScrollArea... Everywhere you see the Layout-with-a-red-crossed-circle icon in the Object Inspector should be looked at.

andre

If you use layouts, you have to use layouts all the way:

Every widget (except the top level one) has to be in a layout
Every widget that contains other widgets has to have a layout.

Recursively.

Ok I understand. Thank Andre!
