Hello, can margin be applied to a view itself instead of on the constraint ?

[Nick]

No. The design choice was to have parents completely own layout instead of children specifying how they’d like to positioned.

So what we are doing is summing up child views height and width to give the parent view a size. But margins on constraint are not calculated which I understand it's intended.

But is there a way to get that margin without hacking stuffs??

You can modify the parent height as part of the constraints, just make it writable (0.9.0). You can do this directly or via a composite property like bottom:

lastView.bottom eq parent.bottom.writable + margin.

This will work as long as the parent isn’t being forced to a smaller size by any outside layout etc., and the views are constrained so they don’t collapse is the parent has a smaller height.

It works. But there's a bug.

If you don't combine with view.height.preserve the UI will freeze, no component will be displayed

[ayodele]

constrain(view){
    <http://it.top|it.top> eq   10
    it.left eq  10
    //it.height.preserve
    it.bottom eq parent.bottom.writable
}

Code to test with. When you uncomment the it.height.preserve it works.
