Test for the qx.ui.popup.Popup widget. qx.ui.popup.Popups are planned as the source constructor for tooltips, menus, ...

There is also a qx.manager.object.PopupManager which hides all registered qx.ui.popup.Popup instances which are configured to auto hide. This is a nice method to omit to show more than one qx.ui.popup.Popup together (omit multiple QxTooltips, ...).
