Diagram.executeCommand Method

Executes the specified command on this diagram.

Namespace: MindFusion.Diagramming
File: Diagram.js

 Syntax

JavaScript

function executeCommand (command)

 Parameters

command

The Command to execute.

 Remarks

If undo/redo is enabled, the command is saved in the undo history or added to the active composite command.

AddItemCommand and RemoveItemCommand objects are created automatically by the control when adding or removing items, both programmatically or interactively. Calling this method explicitly could be necessary in order to save item's state for later undo using a ChangeItemCommand, or to run a custom operation represented by a class derived from Command.

 Example

The following example shows the pattern that should be used to save the state of an item for later undo.

JavaScript

var ChangeItemCommand = MindFusion.Diagramming.ChangeItemCommand;
var DiagramNode = MindFusion.Diagramming.DiagramNode;var diagram = DiagramView.find("diagram").diagram;
var node = diagram.activeItem;
if (node instanceof DiagramNode)
{
    var change = new ChangeItemCommand(diagram, node);
    node.text = "new text";
    node.brush = "red";
    diagram.executeCommand(change);
}
