    <p>I have now been asked by a client to draw a wavy line with the cursor/mouse such as the following:</p> <p><a href="http://www.endeavoursportsgroup.com/images/WavyLine.png" rel="nofollow noreferrer">Wavy Line http://www.endeavoursportsgroup.com/images/WavyLine.png</a></p> <p>I have the following code below which draws a line with the cursor/mouse, but I am stuck on how to make the line "wavy". This is actually modified code from drawing a dashed line I was working on earlier, so there may be some left over code from that which I will remove later.</p> <p>Can someone help me achieve the Wavy Line that I have been asked to create with my code below or suggest another way to achieve this?</p> <p>Thanks in advance!</p> <pre><code>package { import flash.display.BitmapData; import flash.display.Graphics; import flash.events.Event; import flash.events.MouseEvent; import flash.geom.Point; import flash.net.FileReference; import flash.utils.ByteArray; import mx.core.UIComponent; import mx.events.FlexEvent; import mx.graphics.codec.PNGEncoder; public class DrawingArea extends UIComponent { private var isDrawing:Boolean = false; private var x1:int; private var y1:int; private var x2:int; private var y2:int; private var LastX:int = 0; private var LastY:int = 0; public var drawColor:uint = 0x0000FF; public function DrawingArea() { super(); var p1:Point = new Point(); var p2:Point = new Point(); p1.x = 0; p1.y = 0; p2.x = 200; p2.y = 200; addEventListener(FlexEvent.CREATION_COMPLETE, function(event:FlexEvent):void { graphics.clear(); graphics.beginFill(0xffffff, 0.00001); graphics.drawRect(0, 0, width, height); graphics.endFill(); }); addEventListener( MouseEvent.MOUSE_DOWN, mouseDown ); addEventListener( MouseEvent.MOUSE_MOVE, mouseMove ); addEventListener( MouseEvent.MOUSE_UP, mouseUp); } private function mouseDown(event:MouseEvent):void { x1 = mouseX; y1 = mouseY; isDrawing = true; } private function mouseMove(event:MouseEvent):void { if (!event.buttonDown) { isDrawing = false; } x2 = mouseX; y2 = mouseY; if (isDrawing ) { var p1:Point = new Point(); var p2:Point = new Point(); p1.x = x1; p1.y = y1; p2.x = x2; p2.y = y2; graphics.lineStyle(2,0x00FF00,2); graphics.lineStyle(1, drawColor); graphics.moveTo(x1, y1); graphics.lineTo(x2, y2); x1 = x2; y1 = y2; LastX = x2; LastY = y2; } } private function mouseUp(event:MouseEvent):void { isDrawing = false; } } } </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
