Class NotificationManager

java.lang.Object

org.openstreetmap.josm.gui.NotificationManager

class NotificationManager
extends java.lang.Object

Manages Notifications, i.e. displays them on screen. Don't use this class directly, but use Notification.show(). If multiple messages are sent in a short period of time, they are put in a queue and displayed one after the other. The user can stop the timer (freeze the message) by moving the mouse cursor above the panel. As a visual cue, the background color changes from semi-transparent to opaque while the timer is frozen.
