afterGroupMove

Description​

Fires when a group or swimlane is moved one grid step

note

The event fires just for the target element despite the number of selected elements. The ids of dragged elements are provided in the batch parameter of the callback function.

Usage​

"afterGroupMove": ({
    id: string | number, 
    batch: (string | number)[],
    coords: object,
    event: PointerEvent
}) => void;

Parameters​

The callback of the event is called with an object with the following parameters:

  • id - the id of an item
  • batch - an array of moved elements' ids
  • coords - an object with the x and y coordinates of the group or swimlane position after movement, where:
    • x - the horizontal position of the group/swimlane, moving from left to right
    • y - the vertical position of the group/swimlane, moving from top to bottom
  • event - an event object
info

For handling the inner Diagram Editor events you can use the on() method.

Example​

// initializing Diagram Editor
const editor = new dhx.DiagramEditor("editor_container");
// loading data
editor.parse(data);

// attaching a handler to the event
editor.events.on("afterGroupMove", ({ id, coords }) => {
    console.log(`
        Group ${id} is at the position:
            x: ${coords.x} 
            y: ${coords.y}
    `);
});

Change log:

  • The batch parameter was added in the v6.0
  • The callback function takes an object as a parameter since v6.0
