React Diagram - mainToolbar.commands

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

$(function() {
    var diagram = $("#diagram").dxDiagram({
        mainToolbar: {
            visible: true,
            commands: ["fontName", "fontSize", "bold", "italic", "underline", {name: "sayHello", text: "Say Hello", icon: "blockquote"}]
        }, 
        onCustomCommand: function(e) {
            if (e.name == "sayHello")
            alert("Hello!")
        },
    }).dxDiagram("instance");
});

This property accepts one of the following:

• The icon's CSS class if the icon is from an external icon library (see External Icon Libraries)
• The icon in the Base64 format
• The icon in the SVG format. Ensure that the source is reliable.
