Clarion's implementation of Rich Text Format (RTF) is derived from Microsoft's Rich Edit Control, version 3.0. Rich Text provides a storage format for text that keeps the text compatible among different operating systems, and software applications. A rich text control allows a user to enter, edit, format, print, and save text.
The features of Clarion's RTF control include the support for colorized text, fonts, font sizes, bold, italics, underlining, paragraph justification, bullets, undo, redo, cut, copy and paste clipboard functionality, search, print, new open and save to file, ruler, and tab settings.
Clarion's Rich Text support is compatible with both the ABC and Legacy templates. It may only be used in a 32-bit application. Multiple RTF controls may be used on a single window.
Clarion's Rich Text Classes and Templates are wrappers around Microsoft's Rich Edit Control DLL's. The presence of RichEdxx.DLL is required in the Windows/System directory. At press time, there are three versions of this DLL. Complete information as to what version of RichEdit is installed on your target O/S can be found at the Microsoft web site (search for “RichEdit Versions”).
