Abstract

PURPOSE:To provide an information processor capable of preparing application to be displayed on a screen without being conscious of the picture number of an initial picture. CONSTITUTION:The information processor is provided with a picture transition relation table preparing means 2 for preparing a working table 3 for transition relation between plural pictures from application not defining the transited destination of a picture whose display is to be returned to its initial picture, a reference flag setting means 4 for setting up a reference flag on a picture defined as a transited destination picture from another picture to ON, an initial picture judging means 5 for judging a picture holding the reference flag of the table 3 at OFF as an initial picture, and an application preparing means 1 for defining the picture judged as the initial picture as an undefined transited destination picture.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus for creating a screen display application program (hereinafter referred to as an application) including a screen display information and a process of display transition from one screen to another screen.

[0002]

2. Description of the Related Art When creating an application for displaying multiple screens on a conventional information processing apparatus, the programmer defines the display attributes of the display information on each screen and also the icon of the button pasted on the screen. In the description of the program that causes the display to transition to another screen when is pressed, data that identifies the transition destination screen such as the screen number and screen name must be defined as the transition destination data.

[0003]

By the way, the screen display application includes many steps of returning the display to the initial screen displayed at the beginning of execution of the application when the processing is completed on one screen. Therefore, the programmer must always be aware of the screen number, screen name, etc. of the initial screen when creating the application, which complicates the application creation of the screen display.

The present invention has been made in order to solve such a problem, and supports the creation of a screen display application by providing means for discriminating the initial screen from the transition relation between screens in the application. It is intended to provide an information processing device.

[0005]

An information processing apparatus according to the present invention is an information processing apparatus that creates an application program for screen display including processing of display transition to another screen, which is displayed at the beginning of execution of the application program. Means for creating an application program in which the screen transition destination screen for returning the display to the initial screen is undefined, means for creating a table of display transition relations of display screens included in the application program, and from the table, An application that extracts a screen that is not defined as a transition destination of another screen, determines that screen as the initial screen, and defines the transition destination of the screen whose transition destination screen is undefined as the screen that is determined to be the initial screen. And means for completing the program.

[0006]

The information processing apparatus according to the present invention temporarily creates an application with the transition destination of the screen for returning the display to the initial screen undefined, and then creates a table of the display transition relation of the display screen included in the application. Extract the screen that is not defined as the transition destination from other screens, determine it as the initial screen, define the transition destination of the undefined screen to the screen that is determined as the initial screen, and complete the application. Supports screen display application creation.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings showing its embodiments. FIG. 1 shows an information processing apparatus according to the present invention (hereinafter,
FIG. 3 is a block diagram showing the configuration of the device of the present invention). In the figure, 1 is an application creating means for creating an application for displaying a screen including transitions between a plurality of screens, 2 is a screen transition relation table creating means for creating a working table 3 in which a transition destination of each screen is described based on the application. Reference numeral 4 is a reference flag setting means for setting the reference flag of the screen which is the destination of the other screen to ON with respect to the working table 3, and 5 is the working table 3.
It is an initial screen discriminating means for discriminating a screen which is not a jump destination from any screen as an initial screen on the basis of the reference flag of 1. Initially, the initial screen, which is the jump destination, is defined as the jump destination of the screen that has not been defined, and the application is completed.

FIG. 2 is a conceptual diagram schematically showing the transition between screens in an application. In the figure, ~ are serial numbers of screens, and A to D and R are buttons for changing the display to other screens. In the application of this embodiment, when the button "A" on the screen is pressed, the screen is displayed again, and the button "B" is displayed again.
Press to switch to the screen, press the screen button "C" to switch to the screen, and press the screen button "D" to switch to the screen. When the screen and the button "R" on the screen are pressed, the screen changes to the initial screen respectively. In the original application, the jump destination of the initial screen is defined by the data that specifies the transition destination screen, such as the screen serial number. Not not.

Next, the procedure for discriminating the initial screen by the device of the present invention will be explained based on the flowchart shown in FIG. 3 and the conceptual diagram of the working table 3 shown in FIG. When the application creating means 1 creates an application in which the transition of the screen with the initial screen as a jump destination is undefined (S1), the screen transition relationship table creating means 2 causes the buttons on all screens included in this application and A working table 3 as shown in FIG. 4, which is associated with the jump destination screen when the button is pressed, is created (S2). However, if the jump destination screen is the initial screen, the jump destination is undefined, so the jump destination field is left blank (S3).

The reference flag setting means 4 checks the working table 3 and sets the reference flag of the screen which is the jump destination from another screen to ON (S4). The initial screen discrimination means 5 judges whether or not the reference flag of each screen is OFF (S5), and when it is OFF, judges whether or not there is one screen with the reference flag OFF (S6). If there is only one screen with the reference flag being OFF, this screen is discriminated as the initial screen (S7). However, if there are multiple screens for which the reference flag is OFF, the application is not completed and the initial screen cannot be found, so an error is output and the process ends. In the present embodiment, among all the screens, only the screens have the reference flag set to OFF and are not defined as the jump destination, so that the screen is determined as the initial screen.

As a result of the determination of the initial screen as described above, the application creating means 1 completes the application by defining a screen jump destination whose initial screen is a jump destination, which is initially undefined.

[0012]

As described above, the device of the present invention does not require the programmer to be aware of the screen number of the initial screen when creating an application for screen display, and thus has an excellent effect of facilitating the creation of an application for screen display. Play.
