Is there any solution for this? We need parallel edges, but not that way how ParallelEdgeLayout makes that.
I tried to rewrite the layout function of parallel layout to move the edges, but edges has no usable geometry: x, y, width, height are 0. There I couldn't move them anywhere.
Tried to use setStyle
, but did not do anything:
var s = model.getStyle(parallels[i]) + 'entryX='+x0+';exitX='+x0+';'
console.log(s)
model.setStyle(parallels[i], s);
Oh my God. Here is a solution, Not the dream edges. but almost.., Maybe there are more beautiful solutions (post one): but this is mine for showing real parallel edges:
var spx = 1 / 22;
var spy = 1 / 8;
var x0 = 0.5;
var y0 = 0.5;
for (var i = 0; i < parallels.length; i++) {
var source = view.getVisibleTerminal(parallels[i], true);
var target = view.getVisibleTerminal(parallels[i], false);
var src = model.getGeometry(source);
var trg = model.getGeometry(target);
var srcx = src.x, srcy = src.y, trgx = trg.x, trgy = trg.y;
if (parallels[i].getParent() != source.getParent()) {
var pGeo = model.getGeometry(source.getParent());
srcx = src.x + pGeo.x;
srcy = src.y + pGeo.y;
}
if (parallels[i].getParent() != target.getParent()) {
var pGeo = model.getGeometry(target.getParent());
trgx = trg.x + pGeo.x;
trgy = trg.y + pGeo.y;
}
var scx = srcx + src.width; // source element right
var scy = srcy + src.height; // source element bottom
var tcx = trgx + trg.width; // target element right
var tcy = trgy + trg.height; // target element bottom
var dx = tcx - scx; // len x
var dy = tcy - scy; // len y
var sourcePointX, sourcePointY, targetPointX, targetPointY;
if (Math.abs(dx) > Math.abs(dy)) { // horizontal
sourcePointY = y0;
targetPointY = y0;
if (srcx < trgx) { // left to right
sourcePointX = 1;
targetPointX = 0;
} else {
sourcePointX = 0;
targetPointX = 1;
}
} else {
sourcePointX = x0;
targetPointX = x0;
if (srcy < trgy) { // top to bottom
sourcePointY = 1;
targetPointY = 0;
} else {
sourcePointY = 0;
targetPointY = 1;
}
}
this.graph.setConnectionConstraint(parallels[i], parallels[i].source, true, new mxConnectionConstraint(new mxPoint(sourcePointX, sourcePointY), true));
this.graph.setConnectionConstraint(parallels[i], parallels[i].target, false, new mxConnectionConstraint(new mxPoint(targetPointX, targetPointY), true));
if (i % 2) {
x0 += spx * (i + 1);
y0 += spy * (i + 1);
} else {
x0 -= spx * (i + 1);
y0 -= spy * (i + 1);
}
}
