[Moose-dev] Re: RTLabelled doesn't respect bezier line

Hi Peter!

Indeed, this is a valid point you are making. Each trachel shape has a path, it should be possible to compute the center of it right? Is this what you are trying to do?

Hi,

apparently RTLabelled (or rather TRConstraint) doesn't respect bezier line (not unexpected), and thus probably also all non-straight-line elements (RTMultiLine, RTSomethingGradientLine, maybe others). I am now working on a solution for our heavily modified dynamic multiline, so maybe the solution would be applicable also for the lines in roassal.

Example:

| v shape  edge els |
v := RTView new.
shape := RTEllipse new size: 10; color: (Color purple alpha: 0.3).
els := (shape elementsOn: (1 to: 3)) @ RTDraggable.
v addAll: els .
RTHorizontalLineLayout on: v elements.

v elements first translateBy: -50 @ 50.
v elements last translateBy: 150 @ 100.

edge := (RTBezierLine new controllingElements: v elements) edgeFrom: els first to: els last.
v add: edge.
edge @ (RTLabelled new text: 'a text').
