Another, related question: is it possible to hide and show UI  
element / groups dynamically? In once case I'd like to change which  
buttons are shown in a dialog, based on the property values, and in  
another I'd like to change what is displayed in a particular area, i.e  
show one of two different groups, again based on a property value.

I checked over the dialog code, and I don't see a standard 'visible'  
or 'hidden' property (looking at FGDialog::makeObject), but perhaps  
there is some other way to achieve this?
