Events

The events module provides a convenient way to emit commonly needed events

Predefined events

• LEFT_MOUSE_CLICK
• LEFT_MOUSE_DOWN
• LEFT_MOUSE_UP
• MOUSE_DOUBLE_CLICK
• RIGHT_MOUSE_CLICK
• RIGHT_MOUSE_DOWN
• RIGHT_MOUSE_UP
• KEY_PRESS
• KEY_DOWN
• KEY_UP
• FOCUS - indicates focus was gained
• BLUR - indicates loss of focus
• CHANGE - indicates an input value was changed (mostly relevant to web apps)

The event constants are used like this

var field = new Field('**/the-button');

// Trigger a button's click listener directly
field.emit(Events.LEFT_MOUSE_CLICK);

// A key event
field.emit(Events.KEY_DOWN, 'Enter');

There are more event emitting examples in the Emit api section.
