Jason, how could ListView know the size of elements inside it?
ListView instantiates and destroys elements on demand. It maintains some amount
of content to show what's visible + a little more and you can get its height
via contentHeight.
However, contentHeight itself is dependent on the amount of height available
(and the data model). So it is available only after ListView is fully
constructed.
If your model has small amount of elements and delegates are small, you can
resize ListView after construction so that it fits everything. Here is an
example: http://pastebin.com/qsTp7QT5
Note, however, that this example assumes the ListView instantiates the whole
model during construction - that is unreliable and won't work for all possible
models.
Artem.
