I’ve a noob trouble but I can’t solve it.
So I just want to fill up all height space. It’s a tab that has only one component.
I’ve tried:
[color=#bfbfbf]
Looks like your using the CustomComponent. Then you also need to set its size to 100% x 100% (the default size is 100% x undefined), so the contained layout component can expand to full height (100% * undefined == undefined == 0 in the browser).
So adding setSizeFull() to the constructor of your CustomComponent might solve the problem. Note, that you also need to specify the height of the layout where you place that CustomComponent, otherwise the same thing will happen, the outer layout will suppress the 100% height of the CustomComponent.
