Forcing an update
qooxdoo versions prior to 0.7 sometimes had the problem that there could be an delay between setting a value in an object, and that value appearing on the display of the browser.
The cure for this was qx.ui.core.Widget.flushGlobalQueues().
With qooxdoo 0.7 this is no longer needed! The framework will now automatically do the flush.
For more information about queues, see this article.
