Thank you James, it worked quite well. I printed out the getTextHeight() from
the onheight event in the debugger. I got three firings of the event, the
first one reports zero height, the second two are identical and report the
correct height. Setting the containing view height to this value works like
a charm.
And now on to my next challenge: The view that contains the text and that is
having its height adjusted is actually a node in a k_tree. Unfortunately,
k_tree uses a preset static height to space the nodes out in the y
direction. I have looked at the code in k_tree_controller.lzx where these
nodes are laid out according to a simple even spacing scheme. I need to make
the vertical spacing adjust according to the height of the individual nodes.
If anyone has done something like this, please share.
