🎨 OCaml Paint Interface

An OCaml-based graphical paint application that allows users to draw various objects using an intuitive interface with 14 interactive widgets. This project leverages the OCaml Graphics library, Queue data structures, and custom modules for widgets, GUI management, and event handling to create a robust and scalable paint program.

✨ Features

• 🖌️ Interactive Drawing Tools
  Users can draw shapes, lines, and other objects using a set of 14 interactive widgets.

• 🎚️ Customizable Line Thickness
  Includes a custom slider for adjusting line thickness, implemented using controllers and mouse click/drag events.

• 🏗️ Modular Design
  Built with modular components such as Widget, GUI, and Event Loop modules to ensure scalability and maintainability.

🔧 Technical Details

• The Graphics library was used to render the interface and handle drawing operations in a separate window.
• A Queue data structure was utilized to manage user inputs and events efficiently.
• The event loop processes mouse clicks, drags, and other interactions to dynamically update the GUI.
• The application architecture consists of three main layers:
  • Application Layer (paint.ml): Implements the paint logic.
  • GUI Toolkit Layer (widget.ml, gctx.ml): Manages widgets and graphical contexts.
  • Native Graphics Layer (OCaml Graphics Module): Handles low-level drawing operations.

🗂️ File Descriptions

Note: Not all files required to run the GUI are included in this repository. Only the files where significant contributions were made are provided.

• gctx.ml
  Contains functions for managing graphical contexts, including rendering shapes and handling coordinate transformations.

• gctx.mli
  The interface file for gctx.ml, defining the module's exposed functionalities.

• paint.ml
  Implements the main logic of the paint application, including event handling, widget integration, and drawing operations.

• widget.ml
  Defines various interactive widgets (e.g., buttons, sliders) used in the GUI for user interaction.

• widget.mli
  The interface file for widget.ml, specifying the types and operations available for widgets.

🛠️ How to Run

1. Clone this repository to your local machine: git clone https://github.com/muditm006/OCaml-Paint.git cd OCaml-Paint
2. Set up your OCaml environment:

• Install OCaml if it's not already installed on your system.
• Ensure that the graphics.cma library is available in your OCaml installation.

3. View/build off of the provided files as needed to extend or customize functionality.

📝 Notes

• This project demonstrates how to build a fully functional GUI application in OCaml using a layered architecture.
• The Graphics module provides portable drawing primitives that run in a separate window.
• The modular design makes it easy to extend functionality by adding new widgets or features.
• Ensure that you have the necessary permissions to run graphical applications on your system (e.g., X11 support on Unix-based systems).
