Hello,
I have an mc which loads an external image file (a user avatar)
using MovieClipLoader.loadClip and while doing so displays
percentage of currently loaded bytes in a TextField loaded_txt:
class User extends MovieClip {
private var loaded_txt:TextField;
private var avatar_mc:MovieClip;
private var loader_mcl:MovieClipLoader;
public function User() {
loaded_txt.text = '0%';
var listener:Object = new Object();
// pass container dimensions and
// the TextField reference to the callbacks:
listener.box_width = avatar_mc._width;
listener.box_height = avatar_mc._height;
listener.box_ratio = avatar_mc._width / avatar_mc._height;
listener.loaded_txt = loaded_txt;
listener.onLoadProgress = display_progress;
listener.onLoadInit = resize_clip;
loader_mcl = new MovieClipLoader();
loader_mcl.addListener(listener);
loader_mcl.loadClip(image, avatar_mc);
}
I'm trying to pass 4 variables as members to the onLoadInit
callback, so that I can delete the percentage text in loaded_txt
and also resize the loaded image to make it fit into the box:
private function resize_clip(target_mc:MovieClip):Void {
loaded_txt.text = '';
var clip_ratio:Number = target_mc._width / target_mc._height;
if (clip_ratio > this['box_ratio'])
target_mc._xscale = target_mc._yscale =
100 * this['box_width'] / target_mc._width;
else
target_mc._xscale = target_mc._yscale =
100 * this['box_height'] / target_mc._height;
};
The code above with this['box_ratio'] works, but if I try
to refer to this.box_ratio or just box_ratio, I get the error
message (and same for box_width and box_height):
There is no property with the name 'box_ratio'.
Why is it so? And what irritates me even more, I'm able
to access loaded_txt.text from the callback just fine...
I've tried to print out properties of this in resize_clip(),
but haven't noticed there anything special:
--- this in resize_clip() ---
onLoadInit: [type Function]
onLoadProgress: [type Function]
loaded_txt: _level0.user_mc.loaded_txt
box_ratio: 1.32786885245902
box_height: 61
box_width: 81
Regards
Alex
