Hi, Some of my classes extend Path or Group and constructed by non-trivial algorithms that may use many properties, either standard (like strokeWidth) or non-standard ones. Setting a property calculates a new state at present. When several properties are set it means a lot of unnecessary calculations done.
I would like to delay geometry/shape calculations similar the way Node/Shape do. They signal their state changes by dirty flagging and on pulse necessary synchronization does recalculations when being dirty. However relevant methods despite being public are deprecated (tipically ones starting with impl_) and cannot be relied upon. Is there a way to achive that kind of design for own classes? Thx! Zsolt
