Perspective - Text Area

Component Palette Icon:

Description

Suitable for multi-line text display and editing. Will scroll vertically on demand. Horizontal scroll is determined by the "wrap" property.

Properties

Most Properties have binding options. For more information on Bindings, see Types of Bindings in Perspective. This section only documents the Props Category of properties. The other Categories are described on the Perspective Component Properties page.

Name	Description	Property Type
text	Text to display.	value: string
placeholder	Text displayed when Text Area is empty.	value: string
enabled	If true, user is allowed to alter text.	value: boolean
deferUpdates	When true, updates to props.text will be deferred until focus is lost or enter is pressed.	value: boolean
rejectUpdatesWhileFocused	When true, props.text will not accept updates from external sources while focused.	value: boolean
resize	Sets whether text is resizable, and if so, in which direction: none, both, horizontal, or vertical.	value: string
wrap	Specifies how to wrap text: hard, soft, or off. (Soft wrap is the break resulting from a line wrap or word wrap. Hard wrap is an intentional break, which moves text to the next line, or creates a new paragraph).	value: string
style	Sets a style for this component. Full menu of style options is available for text, background, margin and padding, border, shape and miscellaneous. You can also specify a style class.	object
spellcheck	When true, text containing potential spelling errors will be underlined in red while the text is being edited in a launched session. Be aware there may be some slight behavioral differences in spellcheck error detection depending on the session browser.	value: boolean

Component Scripts and Events

Further component interaction and functionality can be configured for all components through scripting and event actions. Right-click on the component or select Components from the Designer menubar to access the configuration popups for both of these options:

• Configure Events: Accesses the Event Configuration popup where you can configure actions to run in response to events to make the component dynamic. The Events Configurations page shows how to configure events and actions on a Perspective component.

• Configure Scripts: Accesses the Script Configuration popup where custom methods and message handlers can be added. The Scripting in Perspective section details scripting fundamentals, creating custom methods, and using message handlers.

Example
