Description

WML card layout method of wireless terminal {WML CARD RAYOUT METHOD OF WIRELESS TERMINAL}

The present invention relates to a WML card layout method of a wireless terminal, and more particularly to a WML card layout method of a wireless terminal to display text and images using a Rectangle.

Wireless Markup Language (WML) for use in wireless terminals defines a user interface for wireless terminals, which includes four main functional areas: text presentation and layout areas, Card configuration area, inter-card connection area and character string (correlating text strings with variables) and state management area.

In the text presentation and layout area, WML includes text and image support, which includes various presentation and layout commands.

For example, text in highlighted text may be defined in the text presentation and layout area.

In the card configuration area, the WML is a page in which all information is organized into a card and a set, wherein the cards are pages defining one or more user interaction units (e.g., selection menus, screens of text or text input fields).

The user navigates through a series of cards, reviews the contents of each, enters the required information, selects it, and moves it to another card.

In the inter-card connection area, WML includes support for explicit management between cards, and also includes provisions for handling events within mobile devices, while WML includes links similar to those found in HTML4. It supports fixed links.

In the string parameterization and state management area, WML allows the deck to be parameterized using a state model, where variables can be used in place of the string and replaced at runtime.

That is, the WAP (Wireless Application Protocol) browser of the wireless terminal develops and uses WML (Wireless Markup Language) and WML Scripts similar to the HTML (Hypertext Markup Language) used in the wired Internet, and implements the WAP service procedure Explain.

First, since a radio link is basically set up for a data service by receiving a call connection request from a user, a URL is requested to the user WAP terminal after accessing the data call.

Then, request information including the URL of the wireless terminal to the WAP gateway and receives the subscriber confirmation.

The WAP gateway parses the request (confirms the syntax) and makes a request to the web server in HTTP form, which then parses the request and decides what to send.

If the URL requests a static file, the web server sends it. If it is a CGI program, it executes the program.

Thereafter, the web server attaches the result of the static file or the CGI program to the HTTP header, and sends the result to the WAP gateway. The WAP gateway parses the response and verifies WML authorization (HTTP header deletion) and sends it to the browser of the terminal.

The browser of the wireless terminal then parses the response and sends the information to the user.

The WML layout method used in the above-described WAP browser shows a text and an image in different line units, that is, a technique for displaying text and an image in different lines is mostly used.

Therefore, when you want to show the picture and text on the same line or when you display the text, it is not laid out on one line but laid out over several lines. Therefore, there is a problem that the speed is lowered.

The present invention has been made to solve the above problems, and an object thereof is to provide a WML card layout method of a wireless terminal to display text and images using a Rectangle.

1 is a flowchart illustrating a WML card layout method of a wireless terminal of the present invention.

Figure 2 is a schematic diagram showing a basic object shown on the screen of the wireless terminal in Figure 1;

3 is a view showing the configuration of a basic object on the terminal screen using a Rectangle in Figure 1;

The present invention for achieving the above object, the first process of constructing a Rectangle in units of NEW BREAK and NEW BREAK to layout the object shown on the terminal screen; A second step of determining whether or not the Rectangle configuration is completed for the card after calculating and storing layout information about each Rectangle; As a result of the determination of the second process, when the construction of the Rectangle for the card is completed, the third process may be performed by displaying only an area viewed by using the information in the Rectangle.

Hereinafter, operations and effects on the WML card layout method of the wireless terminal according to the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating a WML card layout method of a wireless terminal of the present invention, and a first process of constructing a Rectangle in units of NEW BREAK and NEW BREAK to lay out an object displayed on a terminal screen as shown in the drawing; A second step of determining whether or not the Rectangle configuration is completed for the card after calculating and storing layout information about each Rectangle; As a result of the determination of the second process, when the construction of the Rectangle for the card is completed, a third process of displaying only an area shown by using the information in the Rectangle is described. The operation of the present invention will be described.

First, the web browser parses a WML card and lays out a layout for each object, and then displays the object on the terminal screen. Here, the WML card is a terminal screen such as a key, text, image, option, and input. It consists of a base object shown in the table and a selector that allows you to organize the basic object by grouping it.

2 is a schematic view showing a basic object directly displayed on a terminal screen, wherein the basic object includes a title, an image, text, an option, a user input window, and a border of a table.

As shown in FIG. 3, the basic object is laid out by grouping between a new break (New Break = New Line) and a new break (New Break = New Line) in a Rectangle.

In other words, grouping of basic objects, New Break, which has a similar meaning as Newline in general editor, is used as a separator, and all the objects in between are placed in one Rectangle for layout convenience.

In addition, by performing FLICKERING (the ability to automatically scroll left and right for long text) in units of Rectangle, the programming procedure can be simplified, and the Rectangle list can be easily placed in a WML card to easily scroll up and down.

In other words, after calculating layout information in one Rectangle in advance, only this information is used when scrolling left and right or up and down, so it is fast in terms of speed and easy in procedural aspects.

Referring to FIG. 1, first, in order to lay out an object displayed on a terminal screen, each Rectangle is configured in units of NEW BREAK and NEW BREAK, that is, the Rectangle analyzes the contents of the WML card and selects each basic object. It consists of a linked list, and links the linked list of objects in NEW BREAK and NEW BREAK units with the corresponding Rectangle using the head and tail of the Rectangle. Then, the layout information for each Rectangle is calculated and stored. To calculate the space occupied by the base object by searching the base objects consisting of linked lists one by one in each Rectangle, and storing the completion in the Show-flag of the WML card structure containing the Rectangle when this calculation is completed for all Rectangles. Then, when all the Rectangle configurations for the card are complete, the area shown using the information in each Rectangle It displays only the Rectangle list in the WML card, and scrolls up and down, i.e. it determines which Rectangles are in the display area of the currently displayed terminal and displays only the objects connected to overlapping Rectangles. If long text to be NOWRAP is displayed, it is automatically scrolled left and right.

Here, after forming a Rectangle group corresponding to each text object, the layout information is placed in the Rectangle group to perform up, down, left, and right scrolling.

The specific embodiments or examples made in the detailed description of the present invention are for the purpose of clarifying the technical contents of the present invention only, and should not be construed as limited to these specific embodiments by consultation, and the spirit of the present invention and the claims Various changes can be made within the scope of.

As described in detail above, the present invention has an effect of easily and quickly performing automatic left and right scrolling and up and down scrolling by displaying text and an image using a Rectangle.
