What you're trying to do is fine. I suspect that you're just not allowing
time for the cursor to change before beginning your update work. The
browser only changes the cursor appearance when it regains control, so you
need to give the browser control explicitly after setting your cursor but
before beginning your table update. Set your cursor then call the function
that updates your table via a timer:
application.getRoot().setGlobalCursor("progress");
qx.event.Timer.once(
function(e)
{
// update table here
},
this,
20);
I've found that in some cases, I need a timeout of 20 milliseconds as shown
here, and sometimes, a time out of 0 just to release control to the browser
to set the cursor is adequate. The difference is indistinguishable to the
human eye (mine, at least), so I now just tend to use 20ms all the time for
this purpose.
