    start: function() {
        this.app.toolbar.add('mybutton', {
            title: 'My Button',
            icon: '<i class="fa fa-file-alt"></i>',
            command: 'myplugin.toggle',
            observer: 'myplugin.observe'
        });
    },
    observe: function(obj, name) {
        if (somethings) {
            return false;
        }

        return obj;
    },
    toggle: function(params, button) {
        // do something
    }
});

command

Calls the specified method when the button is clicked.

ArticleEditor.add('plugin', 'myplugin', {
    start: function() {
        this.app.toolbar.add('mybutton', {
            title: 'My Button',
            icon: '<i class="fa fa-file-alt"></i>',
            command: 'myplugin.toggle'
        });
    },
    toggle: function(params, button, name, e) {
        // do something
    }
});

The command passes the object with following values:

• params — button parameters
• button — button instance
• name — name of the button
• e — button click event object

params

ArticleEditor.add('plugin', 'myplugin', {
    start: function() {
        this.app.toolbar.add('mybutton', {
            title: 'My Button',
            icon: '<i class="fa fa-file-alt"></i>',
            command: 'myplugin.toggle',
            params: {
                arg1: value1,
                arg2: value2
            }
        });
    },
    toggle: function(params, button, name, e) {
        // get params
        console.log(params.arg1, params.arg2);
    }
});
