for clarification: the reason for using the Form object, as in Form.meta, is to be memory efficient. if you only have 3 possible paint patterns, it would be more efficient to create the objects in advance:
e.g. $meta:=New collection(New object;New object;New object;New object;New object;New object) $meta[0].stroke:=selected_stroke //"#ffffff" $meta[0].fill:=selected_fill_blue //"#61778e" $meta[1].stroke:=selectable_stroke //"automatic" $meta[1].fill:=unselected_fill //-1 $meta[2].stroke:=unselected_stroke_dark_red //"#ff6600" $meta[2].fill:=unselected_fill //-1 $meta[4].stroke:=selected_stroke //"#ffffff" $meta[4].fill:=selected_fill_dark_red //"#bd967d" $meta[3].stroke:=unselectable_stroke //"#d3d3d3" $meta[3].fill:=unselected_fill //-1 $meta[5].stroke:=selected_stroke //"#ffffff" $meta[5].fill:=selected_fill_grey //"#a3a3a3" Form.meta:=$meta then you can select and return the appropriate meta in your meta expression method. of course, you can always return a new object like $0:=new object(“stroke”;”orange”) which is not incorrect, it is just not optimised. ********************************************************************** 4D Internet Users Group (4D iNUG) New Forum: https://discuss.4D.com Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
