Re: how to implement delayed calculation of node/shape
>From Scene doc: "The scene graph detects dynamic node changes which affect layout (such as a change in size or content) and calls requestLayout(), which marks that branch as needing layout so that on the next pulse, a top-down layout pass is executed on that branch by invoking layout() on that branch's root. During that layout pass, the layoutChildren() callback method will be called on each parent to layout its children. This mechanism is designed to maximize layout efficiency by ensuring multiple layout requests are coalesced and processed in a single pass rather than executing re-layout on on each minute change." Parent class has a layoutChildren() method that can be overriden. Do you mean processing my own classes here depending on their dirty state? If not, can you elaborate on that suggestion? Thanks.

how to implement delayed calculation of node/shape
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

Hi, I asked something on Stackoverflow I do not think I can formulate better, but it was closed right away. Is there a mailing list for user questions? Thx, Zsolt
