         [0004]    2. Description of the Related Art 
         [0005]    A screen in a current portable terminal displays only information determined by a developer, and a display range is determined upon programming. For this reason, a user cannot configure the range of display. 
         [0006]    In addition, in most portable terminals, an application is driven in a screen of 3 inches or less. Even when multi-tasking is supported by the portable terminal, only one application of a plurality of applications is displayed on the screen. That is, a user cannot view all of the plurality of applications currently in operation on one screen. 
         [0007]    In addition, a widget may allow a plug-in program desired by a user to be freely displayed on the screen, but the plug-in program should abide by the interface of the widget itself so that it may be displayed. The plug-in program is not directly displayed, but hands over information to be displayed to a widget engine, and the widget engine analyzes this information to display the plug-in program. 
         [0008]    Therefore, a need exists for an apparatus and a method for allowing a user to edit desired information on one screen at a time to view the information on the one screen in a portable terminal.

In addition, according to an exemplary embodiment of the present invention, the controller  420  may provide the function of a widget manager. 
         [0050]    The storage unit  430  stores programs for controlling an overall operation of the portable terminal and temporary data occurring during execution of the programs. More particularly, according to an exemplary embodiment of the present invention, the storage unit  430  stores a document that determines a control signal and an operation method to be used by a display platform engine. 
         [0051]    The display unit  450  displays data output from the controller  420 . In addition, though not shown in the drawing, the display unit  450  has a touch function, and input touch data is provided to the controller  420 . 
         [0052]    When requested by a user to execute a message application, the widget service determining unit  440  executes the message application whose execution has been requested first on a current screen. In addition, when the message application is executed, the widget service determining unit  440  determines and sets a service required for executing the message application in advance from a widget engine. When an event for the set service occurs due to a user&#39;s input command, the widget service determining unit  440  performs the relevant process to meet the service request, thereby raising a message application execution speed. That is, the widget service determining unit  440  allows the message application to access the widget engine through a short circuit. In addition, the widget service determining unit  440  may magnify the message application screen according to the user&#39;s selection corresponding to the user&#39;s screen touch input. 
         [0053]    The widget service determining unit  440  outputs a message application execute window at the upper end of the screen, and outputs a message application input window at the lower end of the screen. The widget service determining unit  440  receives data from the user, and transmits the input message according to the user&#39;s selection. When the user selects end of the message application and an end event occurs, the widget service determining unit  440  ends the message application. 
         [0054]    When requested by a user to execute a message application, the widget service determining unit  440  executes the message application whose execution has been requested on a current screen first. When the message application is executed, the widget service determining unit  440  determines and sets a service required for executing the message application in advance from a widget engine. When an event for the set service occurs due to the user&#39;s input command, the widget service determining unit  440  performs a relevant process to meet the service request, thereby raising the message application execution speed. 
         [0055]    That is, the widget service determining unit  440  allows the message application to access the widget engine through a short-circuit. In addition, the widget service determining unit  440  may magnify the message application screen according to the user&#39;s selection corresponding to the user&#39;s screen touch input. 
         [0056]    Thereafter, the widget service determining unit  440  outputs a message application execute window at the upper end of the screen, and outputs a message application input window at the lower end of the screen. The widget service determining unit  440  receives data from the user, and transmits the input message according to the user&#39;s selection. 
         [0057]    When the user selects end of the message application and an end event occurs, the widget service determining unit  440  ends the message application. 
         [0058]    In the above block configuration, the controller  420  may perform the function of the widget service determining unit  440 . Separate configuration and illustration of the widget service determining unit  440  are for separately describing each function. 
         [0059]    Therefore, in actual realization, all or some functions of the widget service determining unit  440  may be processed by the controller  420 . 
         [0060]      FIGS. 5A through 5D  are illustrations of a message magnification/reduction process according to an exemplary embodiment of the present invention. 
         [0061]    Referring to  FIG. 5A , when a user selects a Short Messaging Service (SMS)-Multimedia Messaging Service (MMS) and, as in  FIG. 5B , requests a portable terminal to magnify the SMS-MMS through a touch input command, the SMS-MMS is executed and magnified by the user&#39;s touch input command as in  FIG. 5C . 
         [0062]    When the user requests the portable terminal to magnify the entire SMS-MMS through touch input command, the SMS-MMS may be executed to an entire screen as in  FIG. 5D . 
         [0063]      FIGS. 6A and 6B  are illustrations of message application driving according to an exemplary embodiment of the present invention. 
         [0064]    Referring to  FIG. 6A , when a user selects an SMS-MMS and requests a portable terminal to input a message on the SMS-MMS execute screen, the user may immediately input a message into an SMS-MMS execute window at the upper end through an input window at the lower end as in  FIG. 6B . 
         [0065]    Compared to the program execute structure which only selects and executes a specific application in a portable terminal, an exemplary embodiment of the present invention may control the size of a window while the specific application is executed, and a user may control the size of an application being executed and display a plurality of applications on one screen even when the plurality of applications are executed. 
         [0066]    In addition, in the related art, when a user reduces a window size of an application, only a partial screen of the application is displayed, which inconveniences the user. An exemplary embodiment of the present invention may display a desired screen, so that a user may use the application more conveniently. 
         [0067]    While the invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and their equivalents.
