How to make a scrollpane adjust to its content?

See stackoverflow question
http://stackoverflow.com/questions/34722545/how-to-make-a-scrollpane-adjust-to-its-content/34751687#34751687

all I came up with is

calling

sp setScrollDeltas.

This will reset (or add or remove) the scrollbars.

I was wondering why something like

rows updateLayout or

rows changed

doesn't work.

Do we have a way to let a ScrollPane "know" when the submorphs changed ?

Some way for listening to newly added submorphs. Or add

the pane to dependents for its scrolled area and notify on changes for submorphs or just

the size?

(The content morph ("rows" in this example) can automatically adjust its

size when we add new submorphs)

sp setScrollDeltas 

Best,
