action : string; A string which parses to one or more valid statements in 1-D Maple Notation. These statements form the Value Changed Action Component Code that executes when the TextArea selection is manually adjusted.

depth : posint:=1; The number of visible rows.

editable : truefalse; Indicates whether the text can be edited.

enabled : truefalse; Indicates whether the component is enabled. The default is true. If enabled is false then the inserted component is grayed out and interaction with it cannot be initiated.

fillcolor : {list(nonnegint),symbol,string}:=[255,255,255] ; Specifies the background color of the component. The passed value can be either a named color or a list of three integers each between 0 and 255. A list of nonnegative integers is interpreted as RGB values in a 24bit 3-channel color space. The default value is [255,255,255] which corresponds to white.

fontcolor : {list(nonnegint),symbol,string}:=[0,0,0] ; Specifies the font color of the component. The passed value can be either a named color or a list of three integers each between 0 and 255. A list of nonnegative integers is interpreted as RGB values in a 24bit 3-channel color space. The default value is [0,0,0] which corresponds to black.

identity : {name,string}; The reference name of the component.

password : truefalse; Indicates whether the text is masked.

showborders : truefalse; Indicates whether the borders of the component are shown.

tooltip : string; The text that appears when the mouse pointer hovers over the component.

visible : truefalse; Indicates whether the component is visible. The default is true.

width : posint:= 10; The number of visible characters per line.

wrap : truefalse; Indicates whether the text is wrapped across lines.

The TextArea command in the Component Constructors package returns an XML function call which represents a TextArea Component.

The generated XML can be used with the results of commands in the Layout Constructors package to create an entire Worksheet or Document in XML form. Such a representation of a Worksheet or Document can be inserted into the current document using the InsertContent command.
