# Notification popups

In addition to managing views, the UIManager also handles notification popup dialogs. Notification popups are used for showing brief messages to the user to indicate activities and events, such as warnings, information messages or the progress of some process. Using notification popups is extremely simple and only requires two methods. Popups can be shown using one method and hidden with another. Popups can also be set to auto-hide after a specified amount of time.

There are three different types of notification popups: "info", "warning" and "wait". The type affects only the appearance of the popup. The "wait" type is intended for use with progress indication.
