基于GEF框架的报表设计引擎设计与实现

Design and implementation of report design engine based on GEF framework

传统报表设计工具样式单一,复用性差,不便维护。针对上述问题,提出了RDXL语言和基于GEF框架的报表设计模型,设计了该模型的框架结构和实现流程,并实现了基于该模型的报表设计引擎系统,同时还对斜线算法和XML文件生成算法作了详细的阐述。该系统不仅支持拖拽的画报表功能,而且能够轻松设计带斜线的复杂报表,还有生成的XML文件提高了跨平台和复用性。

The style of traditional report design tool is indigent, and the reusability and maintainability are not good as well. In view ofthe above problems, RDXL and report design model based on GEF are proposed, the frarnework stmcture and implementation process are designed, and the report design engine system based on this model is achieved. At the same time, the arithmetic of drawing bias and XML files creating are expounded. The system not only supports report design of drag and draw, but also solves the problem of designing complex report with bias. And the created XML files improve the reusability and cross-platform portability.
