2 is a block diagram illustrating a configuration of a framework module according to the present invention.

Referring to FIG. 2, the framework module 100 according to the present invention includes a class information manager 104 that manages class-wide information, an instance generator 101 that generates an instance to be used by an application from the class information, and It includes an instance registration unit 102 for registering the instance generated by the instance generation unit 101, and an instance execution unit 103 for performing the generated / registered instance.

The platform according to the invention supports object orientation, where an object is a software module with the necessary data structures and the functions performed on them. The object does not just have variables, but has the concept of encapsulation, which together defines what the object can do. All objects can only be defined through classes. A class is a template that defines the type of an object. If a class that has attributes and methods common to several objects is defined first, the object is defined again through this class. Each object belonging to a class is called an instance of that class, and a class that is a type of an object is called an object type.

Hereinafter, the user interface framework of the application in the platform according to the present invention having the above configuration will be described.

The user interface framework according to the present invention is a framework through the concept of Object Oriented Programming (OOP) rather than the library concept. The object is an entity that configures the software and operates the actual software. Object-oriented can be described as forming the software as a structured set of objects in which data structures and behaviors are combined.

Objects have attributes of classification that classify objects with the same data structure and behavior as separate and distinguishable identities from other objects. At this time, each object becomes an instance of the belonging class in the categorization, and all objects created in the same class have the same arithmetic functions and have the same data structure and perform the same behavior. The data structure is a collection of data and attributes that objects have.

Accordingly, the object-oriented framework according to the present invention also has the above properties of identification and classification, and child classes of the parent class inherit and use the properties of the parent class, that is, the child class inherits the properties of the parent class. Take it and use it.

In order for an application to use a framework module, an application may be configured to create / register an instance so that the application uses the framework.

At this time, the framework is operated through a function call. The embodiments of the function are shown in the following table.

On the other hand, the overall class structure of the platform framework according to the present invention as shown in FIG.

Referring to FIG. 3, a class according to the present invention internally manages a stack for managing a control to be displayed on a current screen and provides a method for activating or deactivating a control to be displayed on a screen according to each state. (PApp), the mainframe class (PMainFrame), a class that abstracts the LCD screen, and the component class (Component), the top-level class of the component class that can display some shape on the screen and have a parent or child relationship with other components. A class that acts as a container that contains components, and includes a container class that is responsible for focus management of the components it contains, and a control class for controls.

First, the application class (PApp) is a class that executes a unit application and internally manages a stack for managing a control to be displayed on the current screen, and a method for activating or deactivating a control to be displayed on a screen according to each state. to provide. For example, the application class (PApp) provides setNewControl_PApp () as a method to insert the control currently displayed on the screen into the control stack, and popControl_PApp () as a method to remove the currently active control from the stack.

At this time, only the control located at the top of the control stack is actually shown on the screen, and the controls below the top remain inactive. Therefore, you can call these methods when you want to display a control that matches the current state, or when it's finished using the current control.

In addition, the application class (PApp) implements the PAppInterface interface, which defines the methods called by the platform. An instance of this class is used in the Wi-Fi application, which calls the functions (methods) shown in Table 1 above.

In this case, the above application class implements the methods of the PAppInterface interface, but it is implemented as a method that does nothing in practice, so the user should reimplement these methods so that the user can perform his intended purpose. The platform also forwards all events sent to it to the currently active application, which is the processEvent_PApp () method of this class. The processEvent_PApp () method internally calls the preprocessPAppEvent () and processPAppEvent () methods of the PAppInterface interface. The processEvent_PApp () method first calls the preprocessPAppEvent () method and then passes the event to the currently active control. Finally, when the control handles the event and returns control, it is done to call the processPAppEvent () method.

An embodiment of the constructor of the application class and the method of the application class is shown in the following table.

On the other hand, the mainframe class (PMainFrame) is a class that redraws the LCD area and redraws the components included in the application, i.e., abstracts the LCD screen, when the screen needs to be updated. Only one is generated throughout the framework.

An instance of the mainframe class PMainFrame is created when the platform initializes the framework, and a general application cannot be created directly. Accordingly, the mainframe (PMainFrame) class does not include a method directly used by a general application, and the application on the top of the application stack uses an instance of the mainframe class (PMainFrame).

The component class (Component) is a top class class of a component class that has a certain shape on the screen and may have a parent or child relationship with other components. Information (location, size, etc.) and event processing necessary for an actual screen are displayed. Do this.

An embodiment of the constructor of the component class and the method of the component class is shown in the following table.

As shown in FIG. 4, the container class serves as a container including a component, and a container manages focus management of a component included in the container.

Each component can have focus, so that their containers manage which components have the focus, and for this purpose, the movement order of the focus is managed in the form of a linear list.

To this end, the container class is responsible for letting the component decide whether to handle the movement of the focus or the component key when there is a specific key input while the focus is on the specific component. In other words, all events are delivered to the control that has the focus, and the focus value is determined based on the return value of the component.

Examples of constructors and methods of the container class are shown in the following table.

The control class described above includes a list class (ListOR), a check box class, a radio button class, a label class, a label class, a text field class, and other classes used as a single-line selection list. Include.

The list class may be used as a single line selection list, and internally, an item object is created to have an item. Constructor and method embodiments thereof are shown in the following table.

Unlike the radio button described below, the check box class executes a check box, and a plurality of selections can be made within the same group. Examples of constructors and methods thereof are shown in the following table.

The radio button class is a class that allows only one of the buttons in the same group to be selected. Embodiments of constructors and methods thereof are as follows.

The label class is a component that can be used to display text on the screen. If the text is longer than the size of the component, text outside the range of this component is hidden based on the range of this component. You can align vertically and horizontally.

An embodiment of the constructor and method for the label class is as follows.

The text field class is a class that shows a string to a user and allows the string to be changed. Embodiments of constructors and methods thereof are as follows.

Meanwhile, the other class may be divided into a utility class and an event class.

The utility class includes a string class that can have a dynamic string, and a memory manager class that registers an object, stores a reference to it, and destroys all registered objects when this class is destroyed.

Dynamic strings in the string class can be used to allocate a portion of memory at the time of a call to the malloc () function of C language to store the string, and to reallocate and use the memory as much as the size of the new string when the string data is changed. Say a string. In addition, the memory manager class registers an object, stores a reference thereof, and then destroys all registered objects when this class is destroyed. Thus, the user does not have to worry about destroying registered objects. You just need to make sure that when the instance of this class is destroyed, even if the registered object is destroyed, it has no effect on the execution of the program.

The event class is an AWTEvent class that should be inherited by event classes that can be handled by a control that inherits AbstactControl class, and this class is an ActionEvent that is used as an event object to deliver an event generated when a control raises an action event. Includes a Class and a KeyEvent Class that is used as an event object to deliver key events that occur when a key event occurs on a control.

At this time, the AWTEvent class is a class that event classes that can be processed in a control that inherits AbstactControl class should inherit. Event objects of this class or class objects that inherit from this class can be consumed. You can call the consume () method to specify that the event has been handled and consumed by some control. To find out which event object is consumed, call the isConsumed () method.

The ActionEvent Class is used as an event object for delivering an event generated when a control raises an action event. It has an ID that can identify what event is the current event and the one that handles this event can identify the type of current Action Event by this ID.

According to the mobile communication terminal including a mobile platform supporting the object-oriented application framework according to the present invention as described above, as a framework for providing a user interface and other useful classes in the platform of the mobile communication terminal supporting the wireless Internet By applying to the delegated event processing model, the user interface can be easily implemented.
