[Papervision3D] Basic View MOUSE_DOWN event

[Kayomarz]

Hi

My application is trying to capture MOUSE_DOWN events using BasicView.

MOUSE_DOWN events are correctly captured as long as the mouse is _over_ 
objects that are added to the scene.  However, MOUSE_DOWN events are not 
captured if the mouse is on an area that does not contain an object.

Is this behaviour normal or is there something wrong?

Same is true for other mouse events.

How can mouse events be captured even if there were no objects are added 
to the scene?

Below are some code snippets from the application.


Thanks and regards,

Kayo.

public class ControlBasicView extends BasicView
{

        public function ControlBasicView(viewportWidth:Number = 640, 
viewportHeight:Number = 480,
            scaleToStage:Boolean = true, interactive:Boolean = false, 
cameraType:String = "Target")
        {
            super(viewportWidth, viewportHeight, scaleToStage, 
interactive, cameraType);
            this.mouseEnabled = true;
            this.addEventListener(MouseEvent.MOUSE_DOWN, grabMouse);
            this.addEventListener(MouseEvent.MOUSE_UP, releaseMouse);
            this.addEventListener(MouseEvent.MOUSE_WHEEL, wheelMouse);

            .
            .
            .          

        }

        public function grabMouse(event:Event): void
        {
            trace("Mouse Clicked on Basic View");    // Trace occurs 
only if mouse down occurs when it is over an object
           // Trace does not occur if mouse down occurs over empty area
            this.mouseGrabbed = true;
            this.mouseOld.x = this.mouseX;
            this.mouseOld.y = this.mouseY;
        }

}
