Layout size not defined by its members

[hakito]

I have the following problem. I'd like to do a layout as shown in the attachment.

The LayoutStructure looks like this:

hLayout.addMembers(dynForm, listGrid2);
vLayout.addMembers(listGrid1, hLayout);

What i want is: hLayout should have the smallest possible height. (the height of the dynForm).

The problem is, when I set hLayout.setHeight(1) the dynForm is displayed correctly, but the listGrid2 has only height(1).

I tried to set the height with dynForm.getInnerContentHeight() or dynForm.getInnerHeight(). But this doesn't work.

If i don't set a height hLayout is too big and i have a white space below the dynForm.

How do I get hLayout to display as I want?
