Hi there,
I have a question related to HorizontalLayout and Margins of subcomponents.
i have a HorinzonalLayout with with of 100% within a panel with a fixed width. So i expect to see no horizontal scrollbar in the panel, but unfortunately i get one 
My HorizontalLayout contains three buttons, each button has a margin assigned via a css-class.
The first button is aligned middle-left, the other two middle-right, and the first button has an ExpandRatio of 1 the other both of 0.
It looks like the HorizontalLayout does not include the margins into its width-calculation-process.
Would this be a bug or a feature?
I am using 7.0.3.
Best Regards, Andreas
