Responsive Design - Change between many buttons / one button with menu depending on space available

[gde23]

Hi,

I have a UI where there are many QToolButtons in a HBoxLayout.
Now if the monitor size is too small I want to group them in fewer QToolButtons that have a menu instead of individual buttons.

Is there some default mechanism in Qt implemented for this kind of task or do I have to implement it myself?
And if not, is there an example on how to implement this somewhere?

Since it is a common problem I guess somebody has solved it before.

Thanks

Hi
well qtoolbar shows maker and can expand the toolbar.

It will not make a menu out of it. That is something you have to implement yourself. :)
And a layout will not by any means do such thing.

@mjii thanks for the hint with the toolbar. However I prefer the menu and therefore will implement it myself.
There I have one question:
How is it possible to find out if there is enough space for a widget or if it gets vignetted/cut off?

hi

-How is it possible to find out if there is enough space for a widget or if it gets vignetted/cut off?

Well you can use
http://doc.qt.io/qt-5/qrect.html#contains-1
with proper as true.
for the widget and its parents's rect()
(i assume parent adjusts to windows size)
