Hi Paritosh,
Might this code can give you some idea about the implementation if you are
using a class to drawing the line
public class Drawline extends Canvas
{
private var childCreated:Boolean = false; // flag will set true once
all children created in commitProperties()
public function Drawline () {
super();
}
override protected function createChildren():void {
super.createChildren();
}
protected override function updateDisplayList( unscaledWidth:Number,
unscaledHeight:Number ):void {
super.updateDisplayList( unscaledWidth, unscaledHeight );
}
public function set LineColor( value:Number ):void {
this.removeAllChildren();
this.graphics.clear();
drawMyLine( ColorCode );
// create all children again
}
override protected function commitProperties():void{
super.commitProperties();
if ( childCreated == false ) {
// create all children
drawMyLine( ColorCode );
childCreated = true;
}
invalidateDisplayList();
}
private function drawMyLine( ColorCode ):void {
// Your Logic of Drawing Line
}
}
Let me know if it helps you or you will find some better solutions

Thanks Kalpesh,
Ya I can clear and redraw, but how will I get the attributes at run
time for redrawing? Suppose I have drawn a line from (10,10) to
(100,100), with black color. I want to change it to red. Is there any
way to get the values ie (10,10) and (100,100) dynamically?
Thanks,
Paritosh
