Change default Shape Type when drawing or creating a node (Read 2771 times)

	Hi, I saw that the LinkNodeBehavior calls the constructor of the ShapeNode. Whenever I draw a node or drop a node from the list view into the Diagram, I'd like to create a ContainerNode instead. How could I achieve that?

	Hi, What instance is created when you draw with mouse depends on diagram.Behavior property value; try setting it to either DrawContainers or LinkContainers. As for "drop a node from the list view" part, it just clones whatever node instance you drag from the list, so add an actual ContainerNode there. Regards, Slavcho

	When I do that when listening on mousedown event, don't I interrupt the creation of controllers within the Behavior.createController? If mousedown=true, wouldn't I need to distinguish between moving nodes or selecting them and drawing? I created my own list view because I want to stay independent here. Edit: Drawing a container node now works. But somehow panning doesn't work. I even enable it setting Behavior.Pan. What could cause this issue? The canvas is offsetLet and Top but has a width of more than 4000px and height near to 3000px.

	Quote: But somehow panning doesn't work. Have you enabled overflow on the div that contains diagram's <canvas> element? Other than that, try adding a breakpoint on the 'return new PanController' line in your custom behavior code to verify if it's ever hit.

	Yea I set it to true (scroll). I removed my custom behavior for now to avoid side effects.
