QM provides an advanced text editor for working with files, as well as text-based properties in the Property Editor. Besides the usual features expected of a state-of-the-art editor, the QM text editor provides the following features:

Full integration with QM (Cut/Copy/Paste, Undo/Redo, Search/Replace, etc.)
Extended syntax highlighting for C, C++, Make, Tcl, Arduino (C++)
Powerful keyboard shortcuts (e.g., block-indent/unindent, brace-kiss, etc.)

Note: The appearance of the QM text editor, such as fonts and colors, can be customized by means of the QM Style Sheet.

Syntax Highlighting

The Syntax Highlighter supplied with the QM text editor has been customized to highlight the QM-specific constructs, such as:

the Code-Generation Directives ($declare${}, $define${}, $define1${})
the me->... and e->... constructs for accessing the state-machine members and event-parameters, respectively
the standard fixed-width integer types from <stdint.h> header file (uint8_t, uint16_t...)
