Method for displaying long texts

Abstract

The invention discloses a method for displaying long texts. The method includes a mouse message response step: judging whether re-scanning messages need to be transmitted or not, calling redrawing functions by the aid of systems and describing controls again; a width-describable character number computing step: computing front n complete characters describable in the widths fwidth; a word describing step: displaying to-be-displayed characters by the aid of functions DrawText according to data fed by to-be-displayed character information, mouse message response units and width-describable character number computing units. The n is a post-computation feedback value. The method has the advantages that the method is high in efficiency, low in complexity and convenient to apply, excellent word scroll-display visual effects can be realized along with sliding of a mouse, and accordingly each character can be assuredly completely displayed; words of different portions can be displayed according to dragging actions of users and can be statically displayed when the users do not carry out operation, accordingly, large quantities of options can be provided for the users, and the experience can be improved for the users.

Description

Technical field [0001] The invention involves the automotive field, especially a long text display method. Background technique [0002] In the computer system, especially for embedded systems with smaller display areas, it is often necessary to display a string of a certain length in the display area of the specified width, and the length of this string will exceed the width of the display area;The file name of the file is very long. When the file name is displayed, this string cannot be completely displayed in the specified display area.In response to this problem, there are two commonly used schemes: (1) Tripping the characters in the specified area and adding a omission to indicate that some texts have been cut off, which cannot be displayed. Users can only read the displayed text.(2) The automatic periodic rolling display of the string. Although this method can be the user to all the text content, the text is constantly rolling, especially on the same screen. There are multi...

Problems solved by technology

[0002] In computer systems, especially for embedded systems with a small display area, it is often necessary to display a character string of a certain length in a display area of ​​a specified width, and the length of this string often exceeds the width of the display area; for example: a The file name of the file is very long. When displaying the file name, the string cannot be completely displayed in the specified display area.

To solve this problem, there are currently two commonly used solutions: (1) Truncate the characters beyond the specified area and add an ellipsis to indicate that some text is truncated and cannot be displayed, and the user can only read the displayed text

(2) The character string is automatically and periodically scrolled. Although this method allows the user to see all the text content, the text scrolls continuously, especially the text in multiple text display areas on the same screen scrolls together at the same time, making The user is dazzled, making reading more difficult
