This component was created to solve or at least alleviate the lack of RichText component. Component runs on two platforms: Linux (GTK2) / Windows, and has different ways to work on both OS'es.
- Control in Windows is provided by OS API. Win version supports all features that Win32 API has.
- Linux file reading is made by FPC TRTFParser class, with some changes to support images, this class is slower on complex files. Linux version supports only text formatting.
The two most important properties are Paragraph and SelAttributes, one takes care of the attributes of the paragraph and the other attributes of text.
