Dynamic properties in Look'n'Feel

[Pompei2]

Hi,

When writing a look'n'Feel, is it somehow possible to define a property, that is only set depending on something ? A example of what I mean (and why i need it) is that I would like to set the Property "UnifiedMinSize" to a certain value, but only if the window has a titlebar, if it has none, i would like to set the property to another value.

Is it possible to do this within the Look'n'Feel file ?

something like defining the property within the different StateImagery's would be sufficient.
