Although the generic application (nxqddb) is quite useful, many database applications require a special interface. The Fx Toolkit is a set of Itcl and Tcl tools that provide a very high-level interface to the Qddb Tcl commands. This chapter describes the Fx tools and how the tools fit together to form a custom application. Section 8.3 and section 8.5 demonstrate the tools with examples.
This chapter assumes familiarity with Tcl, Tk, and Itcl. If you are not familiar with Tcl, you should review the Tcl man pages and some of the available Tcl literature.
