Updating a jframe

(Nice to see that they've implemented a fix in 1.4, though not using my more elegant implementation suggested in the bug report). They removed when moving from AWT to Swing (because Swing was -- and still is -- hideously slow) as a mechanism to speed up redraws, but then they needed to ensure that threading race conditions didn't kill the UI performance.So they created Swing Utilities to fix these problems.2 Make sure you have made the text-fields as editable.To make them editable, select all the text-fields and right click.Optimisation tricks: It's a shame that multi-threaded access is one of the less well understood parts of Java, since it's got so many good things going for it, and even less so when Sun even document the 'safe rather than sorry' approach.In many cases, outside of construction, a UI doesn't have that much to go wrong -- and if it does, a simple UI call to 'refresh the whole window' is more than sufficient to get it to update the display.

In fact, there's a discussion about the issues surrounding AWT threading, and in particular one of my vociferous bugs in 4030718 regarding the retarded behaviour that 1.2 and 1.3 had forcing to be used with any GUI apps.

Fortunately, there are some tricks that can be used to achieve the 3D effect in a relatively easy way. Raycasting works by sending out a ray from the camera for each vertical bar on the screen and figuring out where that ray collides with a solid object. JFrame;public class Game extends JFrame implements Runnable{ private static final long serial Version UID = 1L; public int map Width = 15; public int map Height = 15; private Thread thread; private boolean running; private Buffered Image image; public int[] pixels; public static int[][] map = ; Note that the map can be reconfigured to whatever you want, what I have here is merely a sample.

Raycasting is also very fast, and some of the first 3D games, like Wolfenstein 3D, used it. The numbers on the map represent what type of wall will be at that position.

Read on for how this is accomplished., these are windows that have transparent portions, allowing the desktop background and other programs to shine through.

Java doesn't provide any way of creating transparent windows without using the Java Native Interface (JNI) (and even then the native platform must support transparency as well), but that's not going to stop us.
