React Diagram - historyToolbar.commands

The history toolbar can contain default and custom commands. Handle the CustomCommand event to respond to a custom command click.

$(function() {
    var diagram = $("#diagram").dxDiagram({
        historyToolbar: {
            commands: ["undo", "redo", {name: "sayHello", text: "Say Hello", icon: "blockquote"}]
        }, 
        onCustomCommand: function(e) {
            if (e.name == "sayHello")
            alert("Hello!")
        },
    }).dxDiagram("instance");
});
