From 4cc61d0449ed463408633016759694bc59badc04 Mon Sep 17 00:00:00 2001 From: Matthew Bastien Date: Mon, 21 Sep 2015 11:16:56 -0400 Subject: [PATCH] Bug 477962 - Create Basic QML Editor with Syntax Highlighting Added a QML Editor which handles basic syntax highlighting for keywords, multi-line and single-line comments, and strings. The highlight colours are similar to that of Qt Creator and cannot be modified by users as of yet.
