[Moose-dev] Re: Draw curved lines in Roassal

Hi Miguel, you can now place the label on the bottom left of an element. view := RTView new. view @ RTDraggableView. shape := RTArc new innerRadius: [ :i | i *50]; externalRadius: [ :i | (i * 50) + 4]; alphaAngle: 45; betaAngle: 135; color: Color black. elems := shape elementsOn: (1 to: 10). view addAll: elems. elems @ RTHighlightable. label := RTLabelled new text: #yourself. label bottomLeft. elems @ label. view On May 20, 2015, at 5:51 PM, Miguel Campusano &lt;mcampusa(a)dcc.uchile.cl&gt; wrote: The behavior is still odd. If I change the previous code to 10 visualize ten arcs: view := RTView new. shape := RTArc new innerRadius: [ :i | i *50]; externalRadius: [ :i | (i * 50) + 4]; alphaAngle: 45; betaAngle: 135; color: Color black. elems := shape elementsOn: (1 to: 10). view addAll: elems. label := RTLabelled new text: #yourself. label left. elems @ label. view The result is this:<labels2.png> I think this happens because it is trying to put the label at the left-center of the arc (encompassing rectangle?). There is a way to put it at the left bottom?

The visualization shows an object with the red line and a grid to understand quickly the position of the object within the range of the sensor (This case, the object is approximately in the center between 2 to 4 meters from the robot) . The visualization is dynamic, ie: the red line is automatically updated overtime ;) <laserscan.png> On Fri, May 15, 2015 at 12:33 PM Alexandre Bergel &lt;alexandre.bergel(a)me.com&gt; wrote: Ok, let us know!
