Component Palette SynEdit.png
SynEdit is an advanced multi-line edit control, which is integrated into the Lazarus. It is the code editor of the Lazarus IDE and is available in the directory "lazarus/components/synedit". It supports Syntax Highlighting, code completion, code folding and includes exporters for html, tex and rtf. It is a fully custom drawn component, meaning that it doesn't wrap native controls of each platform and that no external library is required; this make SynEdit a crossplatform component. Note that the SynEdit available with Lazarus is a fork of the original SynEdit for Borland Delphi, Kylix and C++Builder which can be found in synedit at sourceforge
