JCalculatorUI

A simple calculator user interface done in Swing.

Short Description

A simple Calculator interface done in Swing - demonstrates the following java concepts:

• Subclassing Swing components & Overriding the paintComponent() method
• Nested drop-down menu for setting one of four of Swing's built-in look'n'feels.
• Exception handling
• Inner class action handlers
• Use of Interfaces/Polymorphism
• Use of Layout Managers to make components resizeable
• Anti-aliasing button / control text with dynamically resizable fonts

Build Instructions: Compile & Run Calculator.java.

Known issues:

• Doesn't actually do any math!
• Menu text does not resize with the window, just the buttons & text field do.
• The MAC OS look and feel doesn't load on my machine- I surmise that it's because I'm using the wrong string. The OSX string doesn't appear on the Oracle java web site, but It's still a good demonstration of a JDialog error message, though.

Notes: Developed with Eclipse Indigo Service Release 2, using the Java 7 IDE. Tested on Windows 7 x64 on a 30" monitor @ 2560x1600 resolution. Implemented in two coding sessions over three cups of coffee. ;)
