I am using goJS to show associations between specifically selected points of data in the style of the Concept Map sample, however when I reshape a link between two nodes it doesn’t always update the diagram model, despite .makeTwoWay();
Each node on the diagram will have at least other connected node, and each connected node will have 2 links (to and from)… One of these links is capable of being moved and stored, and one isn’t with the exception of a node that has 6 links (3 to and 3 from) with another node.
I discovered the problem when extracting the diagram model and storing it, as not all the links would be where I placed them. I then tried doing diagram.rebuildParts() on the ‘LinkReshaped’ event, and this just reset them to where they were before if they weren’t saved.
My node template is as follows:
oDiagram.nodeTemplate = goJs(go.Node, "Auto", {
avoidableMargin: new go.Margin(50,50,50,50),
resizable: true,
layoutConditions: go.Part.LayoutStandard & ~go.Part.LayoutNodeSized },
// define the node's outer shape, which will surround the TextBlock
goJs(go.Shape, {
name: "SHAPE",
stroke: "black",
strokeWidth: 2
},
new go.Binding('fill', 'colour'),
new go.Binding('geometryString', 'geoString')), goJs(go.TextBlock, {
font: "bold 10pt helvetica, bold arial, sans-serif",
margin: 4
},
new go.Binding("text", "text")),
new go.Binding("location", "loc", go.Point.parse),
new go.Binding('width', 'width'),
new go.Binding('height', 'height')
);My linkTemplate is as follows
[code]
oDiagram.linkTemplate = goJs(go.Link, {
routing: go.Link.Normal,
reshapable: true,
toolTip: goJs(go.Adornment, “Auto”,
goJs(go.Shape, { fill: “lightyellow” }),
goJs(go.Panel, “Vertical”,
goJs(go.TextBlock, {
font: “bold 12pt helvetica, bold arial, sans-serif”,
textAlign: “center”,
margin: 3
},
new go.Binding(“text”, “text”)
)
)
)}, goJs(go.Shape, {
isPanelMain: true,
stroke: “black”,
strokeWidth: 2
}),
goJs(go.Shape, {
toArrow: “standard”,
stroke: null
}),
goJs(go.Panel, “Viewbox”, {
segmentIndex: 0,
segmentFraction: 0.4
},
goJs(go.TextBlock,
new go.Binding(“text”, “text”)
)
),
new go.Binding(“points”).makeTwoWay()
);[/code]
