Abstract
A system for implementing a wait cursor at a system level. An event driver accepts user driven events, such as keyboard operations or mouse actions, time stamps them and provides them to a window server. The window server provides the event to an event queue of an associated program. This event is referred to as the 'lastEventSent'. The time stamp associated with that event remains with the event through each stage of execution. Each time a program completes execution of an event, the program notifies the window server of the time stamp of the event. This event is referred to as the 'lastEventConsumed'. The time stamp of the lastEventSent is compared to the time stamp of the lastEventConsumed. If the time stamp of the lastEventSent is not equal to the time stamp of the lastEventConsumed, the time stamp of the lastEventSent is compared to the currentTime. If the difference between the time stamp of the lastEventSent and the currentTime exceeds a threshold value, a wait cursor is implemented.
