Event Handlers

focus

focusGained

This event occurs when a component that can receive input, such as a text box, receives the input focus. This usually occurs when a user clicks on the component or tabs over to it.

.source	The component that fired this event.
.oppositeComponent	The other component involved in this focus change. That is, the component that lost focus in order for this one to gain it, or vise versa.

focusLost

This event occurs when a component that had the input focus lost it to another component.

.source	The component that fired this event
.oppositeComponent	The other component involved in this focus change. That is, the component that lost focus in order for this one to gain it, or vise versa.

key

keyPressed

An integer that indicates whether the state was changed to "Selected" (on) or "Deselected" (off). Compare this to the event object's constants to determine what the new state is.

.source	The component that fired this event.
.keyCode	The key code for this event. Used with the `keyPressed` and `keyReleased` events. See below for the key code constants.
.keyChar	The character that was typed. Used with the `keyTyped` event.
.keyLocation	Returns the location of the key that originated this key event. Some keys occur more than once on a keyboard, e.g. the left and right shift keys. Additionally, some keys occur on the numeric keypad. This provides a way of distinguishing such keys. See the KEY_LOCATION constants in the documentation. The keyTyped event always has a location of KEY_LOCATION_UNKNOWN.
.altDown	True (1) if the Alt key was held down during this event, false (0) otherwise.
.controlDown	True (1) if the Control key was held down during this event, false (0) otherwise.
.shiftDown	True (1) if the Shift key was held down during this event, false (0) otherwise.

keyReleased

Fires when a key is released and the source component has the input focus. Works for all characters, including non-printable ones, such as SHIFT and F3.

.source	The component that fired this event.
.keyCode	The key code for this event. Used with the `keyPressed` and `keyReleased` events. See below for the key code constants.
.keyChar	The character that was typed. Used with the `keyTyped` event.
.keyLocation	Returns the location of the key that originated this key event. Some keys occur more than once on a keyboard, e.g. the left and right shift keys. Additionally, some keys occur on the numeric keypad. This provides a way of distinguishing such keys. See the KEY_LOCATION constants in the documentation. The keyTyped event always has a location of KEY_LOCATION_UNKNOWN.
.altDown	True (1) if the Alt key was held down during this event, false (0) otherwise.

.shiftDown	True (1) if the Shift key was held down during this event, false (0) otherwise.

keyTyped

Fires when a key is pressed and then released when source component has the input focus. Only works for characters that can be printed on the screen.

.source	The component that fired this event.
.keyCode	The key code for this event. Used with the `keyPressed` and `keyReleased` events. See below for the key code constants.
.keyChar	The character that was typed. Used with the `keyTyped` event.
.keyLocation	Returns the location of the key that originated this key event. Some keys occur more than once on a keyboard, e.g. the left and right shift keys.
