Dear List, For Mondrian, I encounter a problem with CurveFitter. I tried to isolate the problem in the following code. You just need to doIt in a workspace: -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= | myMorph window pane morphCls | morphCls := Morph subclass: #MyTestMorph. morphCls compile: 'drawOn: aCanvas | curve | super drawOn: aCanvas. aCanvas fillOval: (10@30 corner: 150@290) color: Color lightRed borderWidth: 4 borderColor: Color black. curve := CurveFitter new. curve form: ((Form extent: 4@4 depth: Display depth) fillWithColor: Color lightBlue; yourself). curve firstPoint: 10@30. curve secondPoint: 40@150. curve thirdPoint: 140@290. curve displayOn: aCanvas form. '. myMorph := morphCls new. myMorph extent: 3000 @ 2000. window := SystemWindow labelled: 'My Example'. window extent: 640 @ 480. pane := ScrollPane new. pane scroller addMorph: myMorph. window addMorph: pane fullFrame: (LayoutFrame fractions: (0 @ 0 corner: 1 @ 1)). window openInWorld. -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= What I would like to have, is the curve to go with the oval when I use the scrollbar. Any idea how to fix this? Cheers, Alexandre -- _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: Alexandre Bergel http://www.bergel.eu ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;.
