lzRichEdit

About

This component was created to try to solve or at least alleviate the lack a Rich Text Editor component, this component runs on two platforms Linux (GTK2) / Windows, and has different ways to work on both OSs. The rich text control in Windows is provided by a library (API) and so is much faster than Linux. Linux file reading rich text is made by the FPC RTFPars TRTFParser ie the class, with some changes to support images, this class is just slower to treat rich complex text files, the Linux version only supports formatting text, paragraph and pictures and everything Windows supports what Ole and the APIWindows can offer. The two most important properties are the lzRichEdit Paragraph and SelAttributes, one takes care of the attributes of the paragraph and the other attributes of text.
