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.

height : posint; The height in pixels of the component.

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

image : {string,Matrix,Array}; Image to be displayed on the component, specified as either the name of an external image file or a Matrix or Array as recognized by commands in the ImageTools package. The caption parameter and the image option are mutually exclusive; only one can be supplied.

tooltip : string; The text that appears when the mouse pointer hovers over the component. The default is the empty string (no tooltip).

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

width : posint; The width in pixels of the component.

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