Methods

_removeEventListeners

protected void _removeEventListeners ( )
Removes all of the DOM event handlers from the HTML element(s) that trigger the display of the tooltip.
Returns: void

configContainer

void configContainer ( type , args , obj )
The default event handler fired when the "container" property is changed.
Parameters:
type <String> The CustomEvent type (usually the property name)
args <Object[]> The CustomEvent arguments. For configuration handlers, args[0] will equal the newly applied value for the property.
obj <Object> The scope object. For configuration handlers, this will usually equal the owner.
Returns: void

configContext

void configContext ( type , args , obj )
The default event handler fired when the "context" property is changed.
Parameters:
type <String> The CustomEvent type (usually the property name)
args <Object[]> The CustomEvent arguments. For configuration handlers, args[0] will equal the newly applied value for the property.
obj <Object> The scope object. For configuration handlers, this will usually equal the owner.
Returns: void

configText

void configText ( type , args , obj )
The default event handler fired when the "text" property is changed.
Parameters:
type <String> The CustomEvent type (usually the property name)
args <Object[]> The CustomEvent arguments. For configuration handlers, args[0] will equal the newly applied value for the property.
obj <Object> The scope object. For configuration handlers, this will usually equal the owner.
Returns: void

destroy

void destroy ( )
Removes the Tooltip element from the DOM and sets all child elements to null.
Returns: void

doHide

void doHide ( )
Sets the timeout for the auto-dismiss delay, which by default is 5 seconds, meaning that a tooltip will automatically dismiss itself after 5 seconds of being displayed.
Returns: void

doShow

Number doShow ( e )
Processes the showing of the Tooltip by setting the timeout delay and offset of the Tooltip.
Parameters:
e <DOMEvent> The current DOM event
Returns: Number
The process ID of the timeout function associated with doShow

init

void init ( el , userConfig )
The Tooltip initialization method. This method is automatically called by the constructor. A Tooltip is automatically rendered by the init method, and it also is set to be invisible by default, and constrained to viewport by default as well.
Parameters:
el <String> The element ID representing the Tooltip OR
el <HTMLElement> The element representing the Tooltip
userConfig <Object> The configuration object literal containing the configuration that should be set for this Tooltip. See configuration documentation for more details.
Returns: void

initDefaultConfig

void initDefaultConfig ( )
Initializes the class's configurable properties which can be changed using the Overlay's Config object (cfg).
Returns: void

onContextMouseMove

void onContextMouseMove ( e , obj )
The default event handler fired when the user moves the mouse while over the context element.
Parameters:
e <DOMEvent> The current DOM event
obj <Object> The object argument

obj <Object> The object argument
Returns: void

onContextMouseOver

void onContextMouseOver ( e , obj )
The default event handler fired when the user mouses over the context element.
Parameters:
e <DOMEvent> The current DOM event
obj <Object> The object argument
Returns: void

preventOverlay

void preventOverlay ( pageX , pageY )
