SynEdit tab

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

Chart tab

The Chart tab lists components for use with graphs and charts from the TAChart package. They are not part of the LCL, but most of them are installed by default.

The IPro palette lists components related to display of html pages. They do not belong to the IDE but are needed by the IDE to show the html-formatted popup coding hints and the chm help files.
