graphics
property, which lets you access methods from the Graphics class.
The Sprite class also includes a graphics
property, and it includes other features not available to the
Shape class. For example, a Sprite object is a display object container, whereas a Shape object is not (and cannot contain
child display objects). For this reason, Shape objects consume less memory than Sprite objects that contain the
same graphics. However, a Sprite object supports mouse click events, while a Shape object does not.

Returns a rectangle that defines the area of the display object relative to the coordinate system
of the targetCoordinateSpace object. | DisplayObject | ||
Returns a rectangle that defines the boundary of the display object,
based on the coordinate system defined by the targetCoordinateSpace
parameter, excluding any strokes on shapes. | DisplayObject | ||
Converts the point object from the Stage (global) coordinates
to the display object's (local) coordinates. | DisplayObject | ||
Converts a two-dimensional point from the Stage (global) coordinates to a
three-dimensional display object's (local) coordinates. | DisplayObject | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Evaluates the bounding box of the display object to see if it overlaps or intersects with the
bounding box of the obj display object. | DisplayObject | ||
Evaluates the display object to see if it overlaps or intersects with the
point specified by the x and y parameters. | DisplayObject | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Converts a three-dimensional point of the three-dimensional display
object's (local) coordinates to a two-dimensional point in the Stage (global) coordinates. | DisplayObject | ||
Converts the point object from the display object's (local) coordinates to the
Stage (global) coordinates. | DisplayObject | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||

Examples ( How to use this example )
ShapeExample.as
The following example uses the
ShapeExample
class to draw a circle,
a rounded rectangle, and a square. This task is accomplished by performing the following steps:
- Declare a
size
property for later use in determining the size of each shape. - Declare properties that set the background color to orange, the border color to dark gray, the border size to 0 pixels, the corner radius to 9 pixels, and set the space between the stage edge and the other objects to be 5 pixels.
- Use the properties declared in the preceding steps along with the built-in methods of the Graphics class to draw the circle, rounded rectangle, and square at coordinates x = 0, y = 0.
- Redraw each of the shapes along the top of the stage, starting at x = 5, y = 5, with
a 5-pixel spacing between shapes by using the
refreshLayout()
method.
