I don't think LoadListener is broken, it's just that there's a catch
in using it. The actual loading of the image doesn't take place if
such image is not attached to the document, so if you really want to
load it without the user seeing the actual load, you have to use a
trick like loading it in a hidden part of the document:
//get the size of the window
int width = Window.getClientWidth();
int height = Window.getClientHeight();
//instantiate image and add loadListeners:
Image img = new Image("example.jpg");
img.addLoadListener(yourloadListener);
//attach image to the rootPanel in a place not visible to the user,
this is where the actual loading takes place
RootPanel.get.add(img, width, height);
//use onLoad to put the image in the right place
This has the effect of showing scrollbars (which you can hide) but the
code gets more complicated and it's beyond what I wantedto show you
Cheers,
Salvador
