Simple Paint App

Description

A basic desktop paint application built using Python's Tkinter library. This app allows users to free-draw, erase, and draw predefined shapes like rectangles, circles/ovals, and straight lines. It also includes essential features like color selection, brush size adjustment, undo/redo functionality, and a clear canvas option.

This project is suitable for beginners learning GUI development with Tkinter and demonstrates fundamental concepts of event handling, canvas manipulation, and basic history management.

Features

• Free Drawing: Draw freehand lines on the canvas.

• Color Selection: Choose from a wide range of colors using a color picker.

• Brush Size Adjustment: Control the thickness of your brush strokes and shapes.

• Eraser Tool: Erase parts of your drawing.

• Shape Tools:

  • Rectangle: Draw perfect rectangles.

  • Circle/Oval: Draw circles or ovals.

  • Straight Line: Draw straight lines.

  • Shape tools are accessible via a pop-up menu for a cleaner UI.

• Undo/Redo: Revert or reapply drawing actions.

• Clear Canvas: Clear all drawings from the canvas with a single click.

• Responsive Layout: The canvas and controls adapt to window resizing.
