Hi! In Roassal, I have the following to draw an ellipse: -=-=-=-=-=-=-=-=-=-= fillOval: aRectangle color: aColor borderWidth: aBorderWidth borderColor: aBorderColor |p rect stroke | rect := self virtualToRealRectangle: aRectangle. nativeCanvas pathTransform restoreAfter: [ p:= nativeCanvas createPath: [:path | |halfPi | halfPi := Float pi /2. path absolute; moveTo: rect topCenter; cwArcTo: rect rightCenter angle: halfPi; cwArcTo: rect bottomCenter angle: halfPi; cwArcTo: rect leftCenter angle: halfPi; cwArcTo: rect topCenter angle: halfPi]. nativeCanvas setShape: p. nativeCanvas setPaint: aColor. nativeCanvas draw. stroke := nativeCanvas setStrokePaint: aBorderColor. stroke width: aBorderWidth. nativeCanvas draw ] -=-=-=-=-=-=-=-=-=-= I feel this is not quite right. It produces something like: With the following Roassal script: -=-=-=-=-=-=-=-=-=-= | view el | view := ROView new. el := ROElement on: 'hello world'. el + ROLabel + ROEllipse. el @ RODraggable. view add: el. view open -=-=-=-=-=-=-=-=-=-= It is has if the halfPi variable does not have the right value. I have found example on the web (e.g., https://developer.gnome.org/gtkmm-tutorial/3.2/sec-cairo-drawing-arcs.html.e...) However I was not able to map them in Athens. Help appreciated. This is a bug in Roassal that has been there for too long :-) Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
