[Moose-dev] Re: Brainstorming : composition of shapes

Roassal shapes have been designed to be factory of Trachel shapes. At the end, everything boils down into trachel shapes, which are agnostic to your model. If you want to change the color, you should directly talk to the trachel shape, as with: =-=-=-==-=-=-==-=-=-==-=-=-= view := RTView new. el := (RTCompositeShape new shape1: RTBox new; shape2: RTLabel new) elementOn: 'Element'. view add: el. view canvas addMenu: 'Color' callback: [ el trachelShape shape1 color: Color red. view signalUpdate ]. view open =-=-=-==-=-=-==-=-=-==-=-=-= Actually, this is a bug in Roassal2, and this is the same problem than in your previous example. You can easily bypass this bug by directly talking to the trachel shape. -=-=-=-=-=-=-=-=-= view := RTView new. el := (RTHorizontalCompositeShape new shape1: (RTCompositeShape new shape1: RTBox new; shape2: RTLabel new); shape2: (RTEllipse new size: 10; color: Color blue)) elementOn: 'Element'. view add: el. view canvas addMenu: 'Color' callback: [ el trachelShape shape2 color: Color red. view signalUpdate ]. view open -=-=-=-=-=-=-=-=-= Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
