Examples ( How to use this example )

CapsStyleExample.as

The following example uses the CapsStyleExample class to draw three parallel lines, each with a different line cap style.

The properties of each line are set as follows:
- The line length is set to 80 pixels.
- The border color is set to orange.
- The border size is set to 30 pixels.
- The highlight color is set to gray.
- The highlight size is set to 0 pixels.
- The alpha is set to 1, making it solid.
- The pixel hinting is set to false (strokes not hinted to full pixels).
- The line scale mode is set to normal, which scales the thickness.
- The joint style of the border caps are set to MITER.
- The miter limit is set to 1, indicating that the miter is cut off close to the line.
The class constructor creates three vertical lines, starting at x = 0, y = 0 by calling the drawLine() method three times using the three different line cap styles (none, round, and square). Each of the three calls to the drawLine() method uses the cap style and properties listed previously to draw a vertical line and associated line highlight. The calls first create a new child Shape object and then use methods of the Graphics class to set the line style and draw the lines and highlights. Each instance of child is added to the display list and drawn on the stage.
The connected line segments are redrawn by using the refreshLayout() method at y = 80 pixels and starting at x = 80 pixels, with a 25-pixel separation between the line segments.
