ABSTRACT:
CROSS REFERENCE TO RELATED APPLICATIONS
The entire disclosure of the Japanese patent application No. Hei 11-106739, filed on Apr. 14, 1999, including its specification, claims, drawings, and abstract is incorporated herein by reference.
FIELD OF THE INVENTION
This invention relates to event control, and more specifically to automated delivery of events.
BACKGROUND OF THE INVENTION
In a window system for personal computers or the like, when a plural number of windows are running, to which of the windows the inputs entered through a mouse or a keyboard (event signals, or events) should be given must be determined. Conventionally, an operating system controls to give events to windows that are chosen and activated by an operator.
However, the operation with such a method is cumbersome because the operator must choose and activate an intended window or windows by the use of the mouse, etc.
To solve the above problem, JP-A-Hei 5-11962 proposes to keep a list of windows that can be activated, so that windows are switched sequentially by pressing a specific key. This enables the user to switch windows simply by pressing the specific key. This has put to practical use a simpler method of switching windows than choosing windows by the use of a mouse.
However, even with this conventional art, that the user is required to operate the key is still cumbersome. Using the conventional window system in particular to household-dedicated appliances such as a TV set poses a problem because the operation is required to be simple.
An object of the invention is to provide a technique for solving the above-described problem, making it possible to determine delivery destinations of events without requiring choosing operations by the operator.
Another object of the invention is to provide a technique that enables delivery destinations of events to be changed flexibly.
SUMMARY OF THE INVENTION
(1) The event control device of this invention comprises an event input means for inputting events, a delivery destination determining information storing section storing the delivery destination determining information indicating for every application to which application an event in question should be delivered according to the contents of the event, and a delivery destination determining means for determining to which application the event should be delivered according to the contents of the event and on the basis of the delivery destination determining information and delivering the event accordingly.
Therefore, an event can be delivered to an appropriate application according to the contents of the event, even without the operator choosing an addressed application.
(2) The event control device of this invention is adapted to record the degrees of priority of delivery as delivery destination determining information. Therefore, an event can be delivered to an appropriate application according to the priority degree.
(3) The event control device of this invention further comprises a delivery destination determining information changing means for acquiring information on which application is currently active and for changing the delivery destination determining information on the basis of the acquired information. Therefore, an addressed application may be flexibly changed depending on which application is in operation.
(4) The event control device of this invention is characterized in that the delivery destination determining information storing section comprises an event reception specifying section storing information on whether the event in question should be received or not, according to the contents of respective events, and a delivery priority degree storing section storing delivery priority degree information on to which application the event should be delivered preferentially and in that the delivery destination determining means determines the application to which the event should be delivered and delivers the event on the basis of the description in the event reception specifying section and the delivery priority degree storing section.
Since the event reception specification and the delivery priority degrees are stored separately, delivery destinations may be changed flexibly according to combinations of two pieces of information.
(5) The event control device of this invention further comprises an event reception specification changing means for acquiring information on which application is currently in operation and for changing the description in the event reception specifying section according to changes in the currently operating application.
Since it is arranged that only the application currently in operation is described as the delivery destination of the event to be received, an addressed application is determined quickly.
(6) The event control device of this invention is characterized in that the event reception specification changing means also carries out the process of changing the description in the event reception specifying section according to current operating statuses of respective applications.
Therefore, an addressed application may be flexibly changed according to the operating statuses of respective applications and an appropriate application may be chosen as the addressed application according to the situation.
(6) The event control device of this invention is characterized in that the event reception specification changing means receives description changing instructions from respective applications and carries out the process of changing the description in the event reception specifying section.
Therefore, which event may be received can be specified from the application side. That is to say, it is possible to determine events to be received according to the progress in the process of an application when the application is created.
(7) The event control device of this invention is characterized in that the delivery destination determining information storing section comprises a basic delivery destination storing section in which are described applications to be the basic delivery destinations for respective contents of respective events, and that the delivery destination determining means, in the case an application to which an inputted event may be delivered is not specified in the event reception specification section, delivers the event to the application of the basic delivery destination described in the basic delivery destination storing section.
Therefore, even if the delivery destination of an event is not described in the event reception specifying section, an application of the basic delivery destination may be determined as the delivery destination. Therefore, in whatever status, a status in which no delivery destination application is present can be avoided.
(8) The event control device of this invention further comprises a delivery priority degree changing means for acquiring information on which application is currently in operation and for changing the priority degree in the delivery priority degree storing section according to the change in the currently operating application. Therefore, the delivery priority degree can be changed depending on which application is currently in operation and an appropriate delivery destination application can be chosen according to the situation.
(10) The event control device of this invention is characterized in that the delivery priority degree changing means changes the priority degree in the delivery priority degree storing section in consideration of current statuses of operation of respective applications.
Therefore, the delivery priority degree can be changed according to the operating statuses of respective applications and an appropriate delivery destination application can be chosen according to the situation.
(11) The event control device of this invention is characterized in that a plural number of delivery priority degree tables are stored in the delivery priority degree storing section corresponding to combinations of applications in operation, and that the delivery priority degree changing means changes the prior
