animated custom cursor

[JeanPaulRossi]

hi

I propose this code, it produces an animate cursor:

package 

{

          import flash.display.Sprite;

          import flash.ui.Mouse;

          import flash.ui.MouseCursorData;

          import flash.display.Bitmap;

          import flash.display.BitmapData;

          import flash.geom.Point;

          import flash.geom.Rectangle;

          public class hourglass extends Sprite

          {

                    [Embed(source='immi/busy.png', mimeType = 'image/png')]

                    private var a_busy:Class;

                    public function hourglass()

                    {     var mcd:MouseCursorData = new MouseCursorData();

                          mcd.data = new Vector.<BitmapData>();

                          var b:Bitmap = new a_busy as Bitmap;

                          var h:uint = b.height;

                          for( var i:int = 0; i < int(b.width/h); i++ )

                                                       { var bmp:BitmapData = divBmp(b,new Point(i*h,0)); mcd.data.push( bmp ); }

                          mcd.frameRate = 10;

                          mcd.hotSpot = new Point(h/2-1,h/2-1);

                          Mouse.registerCursor('hourglass',mcd);

                     }

                    private function divBmp(bmp:Bitmap,pos:Point):BitmapData

                    {

                              var imBase:BitmapData = new BitmapData(bmp.width,bmp.height,true,0);

                              imBase.draw(bmp);

                              var immy:BitmapData = new BitmapData(bmp.height,bmp.height,true,0);

                              immy.copyPixels(imBase,

                                                                      new Rectangle(pos.x,pos.y,bmp.height,bmp.height),

                                                                      new Point(0,0));

                              return immy;

                    }

          }

}

where immi/busy.png is an image whit a certain number of square images

now with the code:

     new hourglass;    

     Mouse.cursor = "hourglass";

we can activate the animate cursor, and it works correctly in an simple application of test where works alone, but if I use it in a real application, for example downloading a host file, only one of the frames are displayed.

It seems that don't find the temporal space to advance the frames.

any opinion?

thanks in advance

i don't see a problem using an animated cursor during file loads.  however, if you're also doing something (like a lengthy for-loop) that stops the stage from updating, that would cause a problem with all animation.

[JeanPaulRossi]

of course, i know that any loop removes space from the multitasking, and can also stop the system...but the download is an asyncronous operation that leaves a lot of space to the other elaborations and, however, it was only  an example, the same problem happens if I make an upload, or I read in local file.

[kglad]

are you using flash pro cs5.5?

[JeanPaulRossi]

yes, with XP34 SO

[kglad]

i have no idea what xp34 so is.   in any case, because there's no problem using an animated cursor during a file load and you're having a problem, someone will probably need to download your file to see what you're doing.

[JeanPaulRossi]

pardon , no XP34 but XP32 (winXP32 operating system).

OK, perhaps I must to perform other tests before saying other

[kglad]

i'd recommend creating a test file that contains only the code you showed and only the additional code needed to download a file.
