buildStaticURL

Generates the URL for the spceified static file. Uses the package ID and file name to generate URL.

Return: string

ARGUMENT	TYPE	DESCRIPTION
staticFile	String	Name of a static file inside of the package.

buttonState

Changes state of a navigation button. Finds a navigation button by type and setting properties from params.

Return: undefined

ARGUMENT	TYPE	DESCRIPTION
type	String	Callback
params	Object	An object with the following properties:

byId

Looks up for widget by the generated id, then by the given id.

Return: widget

ARGUMENT	TYPE	DESCRIPTION
id	Number	The identity to use to delete the object

genId

Generates a widget ID unique in scope of the application.

Return: string

ARGUMENT	TYPE	DESCRIPTION
localId	String	Local ID of the widget, unique in scope of the view.

getChildren

Returns all direct children of this widget. Returns all widgets underneath this.containerNode whose parent is this widget. Note that it does not return all descendants, but rather just direct children. Analogous to Node.childNodes, except containing widgets rather than DOMNodes.

Return: array

init

The init method is called on loading a view and usually is used to initialize the widget properties. It is not called, when navigating to the view for the second and all subsequent times. The method initiates widgets and returns widget definition without loading the widgets. The control panel loads the widgets and only after that calls the onShow method. This method can return an array containing definition of widgets that the aps/load method can use. In this case, the lifecycle init => onShow => onContext methods will wait for resolving of the aps/load promise.

Return: any

reset

Resets value and state to what it was at initialization for all children of this view.

Return: undefined

validate

Called by oninit, onblur, and onkeypress. Show missing or invalid messages if appropriate, and highlight textbox field.

Return: boolean
