Class

ScriptUIGraphics

An object used to draw custom graphics, found in the graphics property of window, container, and control objects.

Allows a script to customize aspects of the elementís appearance, such as the color and font. Use an onDraw callback function to set these properties or call the functions.All measurements are in pixels.

Methods

Instances

void closePath ()
Closes the current path.
Defines a line from the current postion (currentPoint) to the start point of the current path (the value of currentPath).

void drawFocusRing (left: Number, top: Number, width: Number, height: Number)
Draws a focus ring within a region of this element.

Parameter	Type	Description
left	Number	The left coordinate of the region. Value is relative to the origin of this element.
top	Number	The top coordinate of the region. Value is relative to the origin of this element.
width	Number	The width of the region in pixels.
height	Number	The height of the region in pixels.

void drawImage (image: ScriptUIImage, left: Number, top: Number[, width: Number][, height: Number])
Draws an image within a given region of the element.
Uses the version of the image that is appropriate to the element's current state.

Parameter	Type	Description
image	ScriptUIImage	The image to draw. This object contains different versions of an image appropriate to various element states, such as a dimmed version for the disabled state.
left	Number	The left coordinate of the region, relative to the origin of this element.
top	Number	The top coordinate of the region, relative to the origin of this element.
width	Number	The width in pixels. If provided, the image is stretched or shrunk to fit. If omitted, uses the original image width. (Optional)
height	Number	The height in pixels. If provided, the image is stretched or shrunk to fit. If omitted, uses the original image height. (Optional)

void drawOSControl ()
Draw the platform-specific control associated with this element.

void drawString (text: String, pen: ScriptUIPen, x: Number, y: Number[, font: ScriptUIFont])
Draw a string of text starting at a given point in this element, using a given drawing pen and font.

Parameter	Type	Description
text	String	The text string.
pen	ScriptUIPen	The drawing pen to use.
x	Number	The left coordinate, relative to the origin of this element.
y	Number	The top coordinate, relative to the origin of this element.
font	ScriptUIFont	The font to use. Default is the font value in this object. (Optional)

Point ellipsePath (left: Number, top: Number, width: Number, height: Number)
Defines an elliptical path within a given rectangular area in the currentPath object, which can be filled using fillPath() or stroked using strokePath().
Returns a Point object for the upper left corner of the area, which is the new currentPoint.

Parameter	Type	Description
left	Number	The left coordinate of the region, relative to the origin of this element.
top	Number	The top coordinate of the region, relative to the origin of this element.
width	Number	The width of the region in pixels.
height	Number	The height of the region in pixels.

void fillPath (brush: ScriptUIBrush[, path: ScriptUIPath])
Fills a path using a given painting brush.

Parameter	Type	Description
brush	ScriptUIBrush	The brush object that defines the fill color.
path	ScriptUIPath	The path object. Default is the currentPath. (Optional)

Point lineTo (x: Number, y: Number)
Adds a path segment to the currentPath.
The line is defined from the currentPoint to the specified destination point. Returns the Point object for the destination point, which becomes the new value of currentPoint.

Parameter	Type	Description
x	Number	The X coordinate for the destination point, relative to the origin of this element.
y	Number	The Y coordinate for the destination point, relative to the origin of this element.

Dimension measureString (text: String[, font: ScriptUIFont][, boundingWidth: Number])
Calculates the size needed to display a string using the given font.
Returns a Dimension object that contains the height and width of the string in pixels.

Parameter	Type	Description
text	String	The text string to measure.
font	ScriptUIFont	The font to use. Default is the font value in this object. (Optional)
boundingWidth	Number	The bounding width. (Optional)

Point moveTo (x: Number, y: Number)
Adds a given point to the currentPath, and makes it the current drawing position.
Returns the Point object which is the new value of currentPoint.

Parameter	Type	Description
x	Number	The X coordinate for the new point, relative to the origin of this element.
y	Number	The Y coordinate for the new point, relative to the origin of this element.

ScriptUIBrush newBrush (type: Number, color: Array of Number | String)
Creates a new painting brush object.

Parameter	Type	Description
type	Number	The brush type, solid or theme. One of the constants ScriptUIGraphics.BrushType.SOLID_COLOR or ScriptUIGraphics.BrushType.THEME_COLOR.
color	Array of Number \| String	The brush color. • If type is SOLID_COLOR, the color expressed as an array of three or four values, in the form [R, B, G, A] specifying the red, green, and blue values of the color and, optionally, the opacity (alpha channel). All values are numbers in the range [0.0..1.0]. An opacity of 0 is fully transparent, and an opacity of 1 is fully opaque. • If the type is THEME_COLOR, the name string of the theme. Theme colors are defined by the host application.

ScriptUIPath newPath ()
Creates a new, empty path object.
Replaces any existing path in currentPath.

ScriptUIPen newPen (type: Number, color: Array of Number | String, width: Number)
Creates a new drawing pen object.

Parameter	Type	Description
type	Number	The pen type, solid or theme. One of the constants ScriptUIGraphics.PenType.SOLID_COLOR or ScriptUIGraphics.PenType.THEME_COLOR.
color	Array of Number \| String	The pen color. • If type is SOLID_COLOR, the color expressed as an array of three or four values, in the form [R, B, G, A] specifying the red, green, and blue values of the color and, optionally, the opacity (alpha channel). All values are numbers in the range [0.0..1.0]. An opacity of 0 is fully transparent, and an opacity of 1 is fully opaque. • If the type is THEME_COLOR, the name string of the theme. Theme colors are defined by the host application.
width	Number	The width of the pen line in pixels. The line is centered around the current point. For example, if the value is 2, drawing a line from (0, 10) to (5, 10) paints the two rows of pixels directly above and below y-position 10.

Point rectPath (left: Number, top: Number, width: Number, height: Number)
Defines a rectangular path in the currentPath object.
The rectangle can be filled using fillPath() or stroked using strokePath().
Returns the Point object for the upper left corner of the rectangle, which becomes the new value of currentPoint.

Parameter	Type	Description
left	Number	The left coordinate relative to the origin of this element.
top	Number	The top coordinate relative to the origin of this element.
width	Number	The width in pixels.
height	Number	The height in pixels.
