QTextEditor

QTextEditor is a lightweight, custom-built text editor implemented in C++ using Qt. It features a core gap buffer data structure for efficient text manipulation and a custom GUI built with Qt Widgets for responsive rendering.

This project serves as a foundational step toward building a modern, extensible text editor with accurate cursor handling, clean rendering, and a responsive user interface.

Features

• Custom gap buffer implementation for efficient insertions and deletions
• Basic keyboard navigation (left, right, insert, delete)
• Smooth cursor rendering with blinking support
• Multi-line text rendering using QPainter
• Minimal UI built on QWidget and QPainter
• Designed for extensibility and clean architecture

Architecture Overview

• TextEditor: Core logic implementing the gap buffer, cursor movement, and text operations
• EditorWidget: GUI layer handling painting, keyboard input, and rendering logic
• main.cpp: Initializes the application window and launches the editor
