Java Graphics

Overview

The Graphics package provides a simple yet powerful framework for creating graphical windows and rendering objects in Java. It supports various graphical elements such as shapes, text, images, and interactive input via mouse and keyboard.

Features

• Basic graphical window (GraphWin) for rendering shapes and images
• GraphicsObject interface for managing graphical elements
• Point class for representing and drawing 2D points
• Interactive user input handling (keyboard and mouse)
• Support for updating and refreshing graphical components

Installation

To use the Graphics package, add the graphics package to your Java project and ensure the necessary dependencies (such as javax.swing and java.awt) are included.

Usage

Creating a Graphical Window

GraphWin window = new GraphWin("My Window", 500, 500, false);

This creates a 500x500 pixel window with the title "My Window".

Drawing a Point

Point point = new Point(100, 100);
point.draw(window);

This creates and draws a point at coordinates (100, 100).

Drawing a Line

Line line = new Line(new Point(450, 123), new Point(350, 150));
line.setWidth(4);
line.setType("dashed");
line.draw(window);

This creates a dashed line with a width of 4 pixels.

Drawing a Circle

Circle circ = new Circle(new Point(245, 180), 55);
circ.setFill(Color.RED);
circ.setWidth(3);
circ.draw(window);

This creates a Circle with a width of 3 and a filled color of red

Drawing a Oval

Oval oval = new Oval(new Point(30, 350), new Point(180, 450));
oval.setFill(Color.YELLOW);
oval.setWidth(10);
oval.setOutline(Color.BLUE);
oval.draw(window);

This creates a Oval with a width of 10 and a filled color of Yellow and a outline collor of Blue

Drawing a Text

Text text = new Text("abcdefghijklmnopqrstuvwxyz\nABCDEFGHIJKLMNOPQRSTUFWXYZ\n1234567890!@#$%^&*()", new Point(250, 100));
text.setFill(Color.BLUE);
text.setOutlineWidth(4);
text.setOutline(Color.BLACK);
text.setBackground(Color.GREEN);
text.setBorderWidth(2);
text.setBorder(Color.ORANGE);
text.setAlignment("center");
text.setFont("Arial", Font.BOLD, 25);
text.draw(window);

This creates Text with a outline of 4 a box around it colored green a border of that box that is orange with aligned text in the center with the arial font at size 25

Drawing a Polyon

Point[] points = {new Point(350, 230), new Point(375, 300), new Point(245, 385)};
Polygon poly = new Polygon(points);
poly.setWidth(10);
poly.setFill(Color.MAGENTA);
poly.draw(window);

This creates a Polygon with a filled color Magenta with a width of 10

Handling User Input

To capture key presses:

int keyPressed = window.getKey();
System.out.println("Key Pressed: " + keyPressed);

To get the current mouse position:

Point mousePos = window.getMouse();
System.out.println("Mouse Position: " + mousePos);
