Thanks for the reply, Alex. measuredWidth & measuredHeight are 0.
explicitWidth & explicitHeight are NaN. The parameters are both 0. The parent that this guy is getting added to is UIComponent (which happens to be a complex item renderer), I'm not sure if that could be playing into this? Out of curiosity, I overrode height, explictHeight and measuredHeight in the component (my class that extends Hbox) and set a breakpoint in each of them--they never get called. The width and height of this component is never explicitly set because I want it to be as big as the HBox. thanks! --- In [email protected], Alex Harui <aha...@...> wrote: > > In updateDisplayList, see if the parameters are 0.
