Hello Flash folk,
Rather stumped here.
Below is a pseudo class that displays an array of dynamically loaded
jpegs. I need to arrange them next to each other, and since their widths
are all different, I am using MovieClipLoader and the onLoadInit event to
get the width and height of the jpeg only after it's loaded. I write these
measurements to an array. So far so good.
My problem comes when trying to read this array: it's empty!
My guess is that the array goes out of scope with the onLoadEvent of the
listener.
Hopefully someone will have some ideas to help me push this rock a little
bit further up the hill.
Thanks!
Daniel.
_global.PhotoAlbum = function(photos_arr:Array) {
this.holders = new Array();//holds movie clips
this.dims = new Array();//i want to put widths and heights here
//methods
this.displayAlbum = function(Void) {
var ref = this;//used within listener event
var loader = new MovieClipLoader();
var listener = new Object();
//event handler to get width and height of loaded jpeg
listener.onLoadInit = function(holder:MovieClip):Void {
ref.setDims(holder._width, holder._height);
}
loader.addListener(listener);
for (locIndex in this.photos) {
var mc:String = "mc" + locIndex;
var holder:MovieClip = createEmptyMovieClip(mc,
getNextHighestDepth());
loader.loadClip(this.photos[locIndex], holder);
holder._lockroot = TRUE;
this.holders.push(holder);
}
this.arrangePictures(this.holders);
trace (this.dims.length) //returns 0 :(
};
//helper methods
this.setDims = function(w:Number, h:Number) {
this.dims.push(w);
this.dims.push(h);
trace (this.dims); //works okay! but only within this scope
};
this.arrangePictures = function(holders:Array) {
trace (this.dims.length) //returns 0 :(
//my goal is to retrieve the widths and heights set by this.setDims,
//but the this.dims array is empty at this point.
//maybe something wrong with the scope?
};
};
//I call it like this:
photos_arr = ["pic1.jpg","pic2.jpg","pic3.jpg"];
album = new PhotoAlbum (photos_arr);
album.displayAlbum();
