Hello, I noticed that RTEllipse doesn’t have the border. Why it is like that? Best regards, Natalia

It does have a border, you just can't change it's width, which is set to 0.005. ~~~~~~~~~~~ e := RTEllipse new size: 30; color: Color white; borderColor: Color black; element. ~~~~~~~~~~~ I believe there was a problem with it's nonuniformity --- it would be thicker on the wider side and vice versa, or something like that. In theory RTSVGPath could be used, but I don't think support for arcs was added yet (and maybe the problem is still there).

Hi Natalia, You can set the border as: v := RTView new. shape := RTEllipse new size: 30; color: Color white; borderWidth: [ :vv | vv / 30 ]; borderColor: Color black. v addAll: (shape elementsOn: (1 to: 10)). RTGridLayout on: v elements. v You questioned whether ellipse are special. I would say that border are rarely required for an ellipse, but for a box it is often necessary. This is just my feeling. Cheers, Alexandre

Interesting; the layout is ignoring the border --- there should be spacing everywhere. It seems that the border is not accounted for in encompassingRectangle and/or containsPoint: as RTDraggable also works only on the inner half of the border.

Also, why does RTEllipse has different units for the border? I.e. why is there division by 30; if I did that with RTBox I would get quite different results. Thanks, Peter On Mon, Jun 8, 2015 at 8:57 PM, Peter Uhnák <i.uhnak(a)gmail.com> wrote:
