Embodiment Construction

[0042] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0043] The invention is suitable for scientific and technological electronic typesetting software and word processing software that need to input various expressions, and provides a system and method for specifying a priority editing area of ​​symbols. Its core idea is: for a symbol with multiple editable areas, you can specify the priority editing area of ​​the symbol to meet the input habits of different users.

[0044] figure 2 It is a structural block diagram of the system for specifying the priority editing area of ​​symbols according to an embodiment of the present invention. Such as figure 2 As shown in , the system for specifying the priority editing area of ​​symbols includes: specifying modules, associating modules and displaying modules. The specified module is connected to the associated module, and the associated module is co...

Abstract

The invention provides a system for indicating a preferentially edited region of a symbol, which comprises an indicating module, an associating module and a display module, wherein the indicating module is used for receiving indicated input and indicating an editable region of the symbol; the associating module is used for establishing an associating relation between the symbol and the indicated editable region and obtaining the editable region; and the display module is used for displaying the preferentially edited region. The invention also provides a method for indicating the preferentially edited region of the symbol, which comprises the steps of: receiving the indicated input and indicating the editable region of the symbol; establishing the associating relation between the symbol and the indicated editable region; and receiving the symbol input and obtaining the editable region associated with the symbol according to the associating relation, and displaying the preferentially edited region. In the system and the method provided by the invention, the preferentially edited region is indicated for the symbol with a plurality of editable regions before an expression is input and the composing is carried out, the preferentially edited region of the symbol accords with the input habit of a user, thus the input and composing efficiency can be improved.

Description

technical field [0001] The invention relates to the fields of electronic typesetting and word processing, in particular to a system and method for specifying a priority editing area of ​​symbols. Background technique [0002] In scientific and technological electronic typesetting and word processing systems, expression typesetting occupies a relatively large proportion and an important position in typesetting content. For traditional scientific and technological electronic typesetting software and word processing software, it is possible to quickly and effectively input expressions in the layout. And displaying it correctly has always been an important manifestation of the value of software. Expressions include arithmetic expressions, logical expressions, string expressions, physical expressions, chemical molecular formulas, chemical reaction formulas, etc. Formulas are also expressions. An expression is a combination of symbols and operators Symbols refer to symbols in exp...
