Scintilla is a widely used text editing component that serves as the foundation for various text editors and Integrated Development Environments (IDEs). However, keep in mind that software projects evolve, and the information may become outdated. Here are some well-known examples:
Notepad++: A highly popular text and source code editor for Windows.
SciTE: The Scintilla Text Editor itself, often considered the reference implementation for Scintilla.
Geany: A lightweight IDE that uses Scintilla and supports multiple programming languages.
Komodo Edit: A free text editor for dynamic programming languages, spun off from the Komodo IDE.
Anjuta: An IDE for C and C++ programming on the GNOME Desktop Environment for Linux, which uses Scintilla for its text editor component.
Code::Blocks: An open-source cross-platform IDE that has the option to use Scintilla as its text editor.
FlashDevelop: An open-source IDE for Flash development, which also uses Scintilla for text editing.
BowPad: A small and fast text editor with a ribbon interface.
JujuEdit: A text editor which is known for handling large files and also uses Scintilla.
Kephra: A text editor written in Perl that uses the WxWidgets toolkit and Scintilla for its editing component.
WxWidgets: Though not a text editor, this library offers wxStyledTextCtrl, a wrapper around the Scintilla component.
These are just a few examples, and there are likely many other lesser-known or specialized editors and IDEs that also use Scintilla. If you're interested in a particular software, it's always a good idea to check its documentation or source code to confirm whether it uses Scintilla.
