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 Dial position is manually adjusted.

anglerange : nonnegative; The range of angles for the position of the dial's indicator. The angle range can be between 0 and 360 degrees.

continuous : truefalse; Indicates whether dragging of the sliding component will result in continuous updates using the action code.

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

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

image : {string,Matrix,Array,identical(none)}; The Image displayed on the dial, specified as either the name of an external image file or a Matrix or Array as recognized by commands in the ImageTools package.

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

majorticks : numeric; The interval between the major tickmarks on the sliding component. The default is .2 times the upper value of rng minus the lower value of rng.

minorticks : numeric; The interval between the minor tickmarks on the sliding component. The default is 1/2 majorticks.

position : numeric; The initial position of the sliding component. If not specified the value of the left endpoint of the rng argument is used.

showlabels : truefalse; Indicates whether values are shown beside tickmarks. The default is true.

showticks : truefalse; Indicates whether tickmarks are shown. The default is true.

startangle : nonnegative; The angle, measured clockwise from straight down, representing the lower value. The angle is between 0 and 360 degrees.

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; The width in pixels of the component.

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