I'll answer my own question as I've found the solution:
You have to create your own:
var DragConnectionCreatePolicy = draw2d.policy.connection.DragConnectionCreatePolicy.extend({})
and then edit the
onMouseUp: function(canvas, x, y, shiftKey, ctrlKey)
There you can add an if-statement and change the code:
if(this.currentDropTarget instanceof draw2d.Port){
var request = new draw2d.command.CommandType(draw2d.command.CommandType.CONNECT);
request.source = this.currentDropTarget;
request.target = this.mouseDraggingElement;
var command = this.mouseDraggingElement.createCommand(request);
if(command!==null){
command.setConnection(this.createConnection());
canvas.getCommandStack().execute(command);
this.currentDropTarget.onCatch(this.mouseDraggingElement, x, y, shiftKey, ctrlKey);
}
}
to -->
if((this.mouseDownElement.parent instanceof customButton1&& this.currentDropTarget.parent instanceof customButton1)
|| (this.mouseDownElement.parent instanceof customButton2&& this.currentDropTarget.parent instanceof customButton1)
|| (this.mouseDownElement.parent instanceof customButton1&& this.currentDropTarget.parent instanceof customButton2)
|| (this.mouseDownElement.parent instanceof customButton3&& this.currentDropTarget.parent instanceof customButton2)
|| (this.mouseDownElement.parent instanceof customButton3&& this.currentDropTarget.parent instanceof customButton1)){
if(this.currentDropTarget instanceof draw2d.Port){
var request = new draw2d.command.CommandType(draw2d.command.CommandType.CONNECT);
request.source = this.currentDropTarget;
request.target = this.mouseDraggingElement;
var command = this.mouseDraggingElement.createCommand(request);
if(command!==null){
command.setConnection(this.createConnection());
canvas.getCommandStack().execute(command);
this.currentDropTarget.onCatch(this.mouseDraggingElement, x, y, shiftKey, ctrlKey);
}
}
}
The customButton1
in this case are the custom created figures (rectsm diamonds,...).
Hopefully that helps someone else
