sizing iFrame in Tab Panel in Dialog

sizing iFrame in Tab Panel in Dialog


Using UI 1.7.1
Trying to load a URL in an iFrame which is placed within a ui.tabs
modified div which is placed within a ui.dialog modified div.
So far it seems to work except for sizing the different elements. The
dialog can be sized using the height and width options but the tabs
have no sizing options. I would expect that if the tabs modified div
and the iFrame width and height are set to 100% they would just expand
as far as they can go inside the limited size of the Dialog.
It doesn't work that way and I wonder if anyone can suggest how to
control the sizes so that the iframe content covers all the available
room in the sized dialog.
