Fast graphical developing system

Abstract

The invention discloses a rapid graphical developing system, which reduces the code workload and provides a WYSWYG visual effect. The technical scheme is that: the rapid graphical developing system comprises: a core data storage unit for storing all the elements in the project; a user editing unit for carrying through development of interface figure; a data processing interface for connecting the core data storage unit and the user editing unit, modification of the user editing unit on the core data updates data in the core data storage unit through the data processing interface. Wherein, the user editing unit comprises: a window editor, which is displayed in the drawing area of the screen window and is able to modify the interface figure visually; a project editor, which is displayed in tree structure and is able to modify project nodes and attribute value, the result is directly displayed in the window drawing area; an item editor, which displays or hides or edits selected item elements; a drawing editor, which is provided with drawing tools in the window editor for design personnel. The invention is applicable for the developing field of telecommunication software interface.

Description

technical field [0001] The invention relates to a software design and development system, in particular to an OSD (On Screen Display, screen display interface) rapid graphic development system of a digital TV based on CGI (Common Graphic Interface). Background technique [0002] In the field of digital TV, OSD interface display technology is used for software development of screen interface. The so-called OSD interface display technology refers to an interface system that provides users with an independent set of software and hardware control functions on top of the video to control various software and hardware control functions of digital TV, as well as to provide programs, signals, and other services. The layer is the hardware initial picture, which is used to initialize the display device. The video layer displays the stream being played, that is, the current program, and the graphics layer displays the OSD (the graphics layer may be divided into 2 layers or more dependi...

Problems solved by technology

[0004] Using the above-mentioned development method, the development efficiency is low, the burden on the programmer is heavy, and the interface effect can only be seen after the program is written and burned into the corresponding embedded device. Any deviation in the effect during the coding process needs to be returned. Rewrite and modify in the integrated development environment, and then compile and link into a new program, which is neither intuitive nor time-consuming

[0005] At the same time, the above-mentioned development methods cannot meet the needs of speed

The needs of different projects for the interface and its functions are diversified. The existing OSD interface software development cannot complete the coding in a relatively short period of time, and because the interface effect is not intuitive, the debugging phase takes too long, which increases the unsatisfactory development. Certainty

Moreover, writing codes in an integrated development environment to complete interface development can generally only be done by programmers, which brings certain limitations to development.
