Add animation to jquery UI dialog resizing

Add animation to jquery UI dialog resizing


Hi,
I have a jquery UI dialog on my page that I would like to resize at
some point.
I would like to add some animation for the resizing proccess
(something like show("slow") )
Unfortunatelly when I do
$("#myDialog").data("height.dialog", 120).show("slow");
The dialog gets resized but I don't see any animation effect...
I'm new to jquery. Am I doing something wrong?
??
