The Tags Component Of T- Syslink Development In Delphi

The article details introduced the interface component---Syslink which is a support markup language, embedded hyperlink component in Windows. The Syslink is an interface window component which supports the markup language, Embedded, can click on hyperlink directly, also can provide the better user experience than the command link button. This component spread used in the graphic interface of Windows. Syslink like a hyperlink which can be display as description by words or contents of word statement, or underline for some special contents, when we click on the location, then the contents will display as we want, like run code in SW interface or open some Web site….etc. It is a frequently using and practical component in computers. As the component like Web hyperlink and able to provide incessantness visual effectiveness, able to provide the trig experience.The Syslink supports markup language, also supports the simple hypertext of anchor tags <A> </A>, and support the basic attribute of anchor HREF and ID, HREF supports any protocol, for example: HTTP, FTP or mailto. The ID is an optional name, each anchor can be making an individual name, but the name should be the only one in the same Syslink. The Syslink will create a serial number for every anchor; it will from “0” to “N”, we uses the serial number to visit the anchor in the Sylink. Through the markup language, the Syslink realized the very good user experience.RAD is the fashion develops methodology in the world, and it can suit the quick change of demand, realize the quick generation change of development. Delphi is the main RAD develop-platform, to support RAD develop the SW, the Delphi runs with the VCL system. VCL has over 500 system component to support the engineer quick development. The VCL system allows the engineer to expand the function of their components, also supports engineer to develop much senior components.It is inconvenience for Syslink development in Delphi as the system is run with structured programming method. This article raise out a good way to develop the SW with Delphi through investigate the function and RAD’s characteristics: Component Package Mode, according this method, we developed a general, reusable component mode: T-Syslink.The design idea of T-Syslink which supports the markup language, embedded hyperlink tags component was based on the function characteristics of the Syslink, combine the currently real situation, message reflection of Windows, component package mode of VCL in Delphi and utilize the construction of VCL. The article through enough practice and experiment, use the RAD tool of Delphi, make the source code, to state the process of the Tags component T-Syslink’s realization. According to this idea, we developed the Attribute Editor, this action makes easy job with engineers, they can develop the SW much efficiency and convenient them to develop the tags component in hyperlink.In the end, the article showed all process of tags component development and some special example to define the design idea with this type of the tags component of T-Syslink. Also showed the advantage of this tags component. Provide all source code for the sample and the component.
