The Path class is a filled graphic element that draws a series of path segments. In vector graphics, a path is a series of points connected by straight or curved line segments. Together the lines form an image. In Flex, you use the Path class to define a complex vector shape constructed from a set of line segments.

Typically, the first element of a path definition is a Move segment to specify the starting pen position of the graphic. You then use the Line, CubicBezier and QuadraticBezier segments to draw the lines of the graphic. When using these classes, you only specify the x and y coordinates of the end point of the line; the x and y coordinate of the starting point is defined by the current pen position.

After drawing a line segment, the current pen position becomes the x and y coordinates of the end point of the line. You can use multiple Move segments in the path definition to reposition the pen.

The syntax used by the Path class to define the shape is the same as the SVG path syntax, which makes it easy to convert SVG paths to Flex paths.

data:String

Taalversie:

ActionScript 3.0

Productversie:

Flex 4

Runtimeversies:

Flash Player 10, AIR 1.5

A string containing a compact represention of the path segments. This is an alternate way of setting the segments property. Setting this property overrides any values stored in the segments array property.

The value is a space-delimited string describing each path segment. Each segment entry has a single character which denotes the segment type and two or more segment parameters.

If the segment command is upper-case, the parameters are absolute values. If the segment command is lower-case, the parameters are relative values.

The following table shows the syntax for the segments:

Segment Type	Command	Parameters	Example
Move	M/m	x y	`M 10 20` - Move line to 10, 20.
Line	L/l	x y	`L 50 30` - Line to 50, 30.
Horizontal line	H/h	x	`H 40` = Horizontal line to 40.
Vertical line	V/v	y	`V 100` - Vertical line to 100.
QuadraticBezier	Q/q	controlX controlY x y	`Q 110 45 90 30` - Curve to 90, 30 with the control point at 110, 45.
CubicBezier	C/c	control1X control1Y control2X control2Y x y	`C 45 50 20 30 10 20` - Curve to 10, 20 with the first control point at 45, 50 and the second control point at 20, 30.

Draw the element. This is the second of three steps taken during the drawing process. Override this method to implement your drawing. The stroke (and fill, if applicable) have been set in the beginDraw() method. Your override should only contain calls to drawing methods such as moveTo(), curveTo(), and drawRect().

Parameters

g:Graphics — The graphic element to draw.

Finalize drawing for this element. This is the final of the three steps taken during the drawing process. In this step, fills are closed.

Parameters

g:Graphics — The graphics element to finish drawing.

Returns the x coordinate of the element's bounds at the specified element size.

This method is typically used by layouts during a call to the measure() method to predict what the element position will be, if the element is resized to particular dimensions.

Parameters

	`width:Number` — The element's bounds width, or NaN to use the preferred width.

	`height:Number` — The element's bounds height, or NaN to use the preferred height.

	`postLayoutTransform:Boolean` (default = `true`) — When `postLayoutTransform` is true, the method returns x coordinate of the element's bounding box top-left corner. The bounding box is in element's parent coordinate space and is calculated from the specified bounds size, layout position and layout transform matrix.

Geretourneerde waarde

Number — The x coordinate of the element's bounds at the specified element size.

measure

()

methode

override protected function measure():void

Taalversie:

ActionScript 3.0

Productversie:

Flex 4

Runtimeversies:

Flash Player 10, AIR 1.5

Calculates the default size of the element. This is an advanced method that you might override when creating a subclass of GraphicElement.

You do not call this method directly. Flex calls the measure() method when the element is added to an IGraphicElementContainer container such as Group using the addElement() method, and when the element's invalidateSize() method is called.

By default you set both explicit height and explicit width of an element, Flex does not call the measure() method, even if you explicitly call the invalidateSize() method. To override this behavior, override skipMeasure() method.

In your override of this method, you must set the measuredWidth and measuredHeight properties to define the default size. You can optionally set the measuredX and measuredY properties to define the default measured bounds top-left corner relative to the origin of the element.

The conceptual point of measure() is for the element to provide its own natural or intrinsic bounds as a default. Therefore, the measuredWidth and measuredHeight properties should be determined by factors such as:

The amount of text the component needs to display.
The size of a JPEG image that the component displays.

In some cases, there is no intrinsic way to determine default values. For example, a simple GreenCircle element might simply set measuredWidth = 100 and measuredHeight = 100 in its measure() method to provide a reasonable default size. In other cases, such as a TextArea, an appropriate computation (such as finding the right width and height that would just display all the text and have the aspect ratio of a Golden Rectangle) might be too time-consuming to be worthwhile.

The default implementation of measure() sets the values of the measuredWidth, measuredHeight, measuredX, and measuredY properties to 0.
