CHAPTER 4: User-Interface Tools Drawing objects 77

Drawing objects

ScriptUI allows you to draw directly on controls to customize their appearance. You do this by calling

methods of the ScriptUIGraphics object

in response to the onDraw event (see “Defining behavior with

event callbacks and listeners” on page 80). These methods take as parameters a number of helper objects

that encapsulate drawing information, including the following:

Bounds

Defines the boundaries of a window within the screen’s coordinate space, or of a

user-interface element within the container’s coordinate space. Contains an array,

[left,

top, right, bottom], that defines the coordinates of the upper left and lower right

corners of the element.

Bounds object is created when you set an element’s bounds property, and this property

returns a

Bounds object.

X An object must contain properties named left, top, right, bottom, or x, y, width,

height.

X An array must have values in the order [left, top, right, bottom].

Dimension

Defines the size of a Window or user-interface element. Contains an array, [width,

height], that defines the element’s size in pixels.

Dimension object is created when you set an element’s size or preferredSize

property. (A

preferredSize of -1 causes the size to be calculated automatically.)

X An object must contain properties named width and height.

X An array must have values in the order [width, height].

Margins

Defines the number of pixels between the edges of a container and its outermost child

elements. Contains an array

[left, top, right, bottom] whose elements define the

margins between the left edge of a container and its leftmost child element, and so on.

Margins object is created when you set an element’s margins property.

X An object must contain properties named left, top, right, and bottom.

X An array must have values in the order [left, top, right, bottom].

You can also set the

margins property to a number; all of the array values are then set to

this number.

Point

Defines the location of a Window or user-interface element. Contains an array, [x, y],

whose values represent the origin point of the element as horizontal and vertical pixel

offsets from the origin of the element's coordinate space.

Point object is created when you set an element’s location property.

X An object must contain properties named x and y.

X An array must have values in the order [x, y].
