Which Layoutmanager isObservingVisibility? [message #977384]

Hi there.

I use some figures that arrange their children using ToolbarLayout.
Now when I hide some children using setVisiblity(false) their space is rendered empty as the layout does not change.

When I found the method setObservingVisibility() I expected that upon making one child invisible the LayoutManager would re-layout the figure and shrink it to the new size. However this does not happen on ToolbarLayout.

Any idea what is going wrong?

Hi, the only LayoutManager that is observing the visibility of figure's children the is the StackLayout.

Thank you for responding, Jan.

Hmm, if that is intentionally then I'd like to see that being documented, or a call to setObservingVisibility(true) to throw an UnsupportedOperationException.

But even more than that I'd like to hide some Elements and thus shrink the Figure. Is there a recommended way of doing that?

I don't think so. The ToolbarLayout just doesn't take the visibility into account. It's an optional feature.

I haven't do that yet, but what about remove that figure from it's parent for a while instead of making it invisible?
