Hello, the class qx.ui.mobile.basic.Image has an event "loaded", that fired when image is loaded. It is pretty nice feature, that is very useful if loading large image on slow connection. It allow developer, for example, show busy indicator and hide it when image is loaded. However, this event fired only once by loading of image: http://tinyurl.com/kzkj5qw
is it possible to find out if image already loaded?
It would be nice to have something like this:
image.addListener("loaded", function(){this.hideBusyIndicator();},this);
image.setSource(URL);
if(!image.isLoaded())
{
this.showBusyIndicator();
}
unfortunately class qx.ui.mobile.basic.Image has not such method as
isLoaded().
Sure, I can save list of all resources, that I have already loaded, but
this solution is not very elegant. Is it other possibility to find out
if resource is already loaded by application?
regards,
Alex
