Hi Farid
I found this post while i was searching for a solution to load previews from
the server. I'm also using a Image Widget to display the previews in a
window... I found a solution that works very well and might serve you as
well (it doesn't show the "Unknown image" errors).
I'm simply using qx.io2.ImageLoader. My "preview window" class has a "image"
property. Heres the apply method of said property:
_applyImage : function(val, oldval){
if(qx.io2.ImageLoader.isLoaded(val)){
// this._img is the Image Widget
this._img.setSource(val);
} else {
// myapp/loader.gif is a loader animation that's defined as
asset
this._img.setSource('myapp/loader.gif');
qx.io2.ImageLoader.load(val, function(src){
this.debug('Image "' + src + '" was successfully
loaded');
this._img.setSource(src);
}, this);
}
},
Works like a charm and makes me love qooxdoo even more. Hehe :)
