awt

Is double buffering (in java) possible with awt? Currently, I'm aware that swing should not be used with awt, so I can't use BufferStrategy and whatnot (I already have some code written in awt that I don't want to rewrite in swing). If double buffering is possible with awt, do I have to write the buffer by hand? Unlike swing, awt doesn't seem to have the same built-in double buffering capability. If I do have to write the code by hand, is there a good tutorial to look at? Or is it just easier/advisable for a novice programmer to use swing instead? Sorry about the multi-step question. Thanks

I am extending JFrame like this: public GameFrame() { this.setBounds(30, 30, 500, 500); this.setDefaultCloseOperation(EXIT_ON_CLOSE); initializeSquares(); } private void initializeSquares(){ for(int i = 0; i < 5; i++){ this.getContentPane().add(new Square(i*10, i*10, 100, 100)); } this.setVisible(true); } However, only one square is being drawn on the screen, does anybody know why? also My Square class looks like this: private int x; private int y; private int width; private int height; public Square(int x, int y, int width, int height){ this.x = x; this.y = y; this.width = width; this.height

I'm trying to write a resolution selection dialog that pops up when a program first starts up. To prevent boring the user, I want to implement the fairly standard feature that you can turn off that dialog with a checkbox, but get it back by holding down the alt key at startup. Unfortunately, there is no obvious way to ask java whether a given key is currently being pressed . You can only register to be informed of new key presses via a KeyListener, but that doesn't help if the keypress starts before the app launches. public class LockingKeyDemo { static Toolkit kit = Toolkit.getDefaultToolkit(

I'm looking for a way to make a line curve through a number of points. It would be preferable to use 3 points although I've considered that in order to give context to the angle of the line entering a point more may be needed to give context to the curve so to speak. In general a start point P1, a control point P2 and an end point P3, the line should curve to P2 from P1 and then curve from P2 to P3. In fact here is a perfect example of the effect I would like to achieve: If I could do this I really would be eternally grateful! In Java so far, I have tried playing around with things such as

In the codebase we inherited the usage of MediaTracker was always done locally in each code block. new MediaTracker(new Canvas()); mediatracker.addImage(i, 1); try { mediatracker.waitForAll(); } catch (InterruptedException e) { } mediatracker.removeImage(i); Deciding this was inefficient, I eventually replaced it with a static instance and method: final static protected MediaTracker mediatracker = new MediaTracker(new Canvas()); static protected void checkImageIsReady(Image i) { mediatracker.addImage(i, 1); try { mediatracker.waitForAll(); } catch (InterruptedException e) { } mediatracker

When rendering a chart with JFreeChart, I noticed a layout problem when the chart's category labels included Japanese characters. Although the text is rendered with the correct glyphs, the text was positioned in the wrong location, presumably because the font metrics were wrong. The chart was originally configured to use the Source Sans Pro Regular font for that text, which supports only Latin character sets. The obvious solution is to bundle an actual Japanese .TTF font and ask JFreeChart to use it. This works fine, in that the output text uses the correct glyphs and it is also laid out
