A qt-based system for automatically generating cross-platform complex flowcharts

Abstract

The invention discloses a QT-based automatic cross-platform complex flow chart generation system. The QT-based automatic cross-platform complex flow chart generation system comprises a flow chart basic drawing element drawing module, a flow chart structural description module, a flow monitoring function supporting module and a flow monitoring application supporting module; the flow chart basic drawing element drawing module performs inheritance and derivation from basic classes provided by QT, and a basic drawing element class of the flow chart is formed; the flow chart structural description module is used for describing the whole flow chart in a structural mode and performing format analysis on the description, and information is placed into a corresponding container; the flow monitoring function supporting module is used for flow chart display style setting, network transmission, database access, connection and closed-ring inspection, and switching of flows of different particle sizes; the flow monitoring application supporting module is used for topological sorting, task scheduling, critical path and shortest path calculation and construction network diagram application supporting.

Description

technical field [0001] The invention belongs to the field of information systems, in particular to a QT-based system for automatically generating cross-platform complex flowcharts. Background technique [0002] The graphical process monitoring interface has the characteristics of intuitive image, easy understanding, convenient interaction and convenient operation, and is the first choice of various application operators and application developers. Based on the Windows platform, various software manufacturers provide many flow chart control products that can be used for secondary development, such as Microsoft Office Visio, EDraw Max, the diagram expert of Edraw, and Diagram Designer, the vector image drawing software, etc. Visio is the most widely used product among them. It can carry out various complex graphic designs, has powerful functions, rich interfaces, and provides graphic element customization functions. [0003] However, under the general trend of localization of...

Problems solved by technology

[0004] Diagram Designer is a powerful cross-platform application that can quickly and easily create professional icons and illustrations in documents. It provides vector drawing tools, libraries, and many preset legend shapes, but it has high requirements for the operating environment of software and hardware; ConceptDraw Office is also a cross-platform control product, but its disadvantage is that it is bulky and has complex interfaces, so it is not suitable for embedding into application systems for secondary development

So far, the market has not found a set of flow chart controls based on domestic software and hardware platforms, complete functions, easy development, small scale, and low requirements on the operating environment
