Java has no method in the Graphics class or subclasses such as setPixel(x, y, col) but you get the same effect with drawLine(x, y, x, y, col), and of course you can getPixel(x, y) by indexing into your array! maybe something like: public class PaintComponent extends JComponent { private int W = 200, H = 200; Color pixels[][]; // = new Color[W][H]; public PaintComponent() { super(); addMouseListener( new MouseHandler() ); } public void paintComponent(Graphics g) { Graphics2D g2d = (Graphics2D)g; for (int x = 0; x < W ; ++x) for (int y = 0 ; y < H ; ++y) g.drawLine(x, y, x, y, pixels[x][y]); // and whatever else (border etc) } class MouseHandler extends MouseAdapter() { //override the handler methods you need } } This code isn;t complete, but gives you an idea of what I mean. You could even implement get/setPixel in this class. You can use the repaint() and repaint(x, y, w, h) to invoke a repaint of your component internally. The 2nd clips the region to redraw. You can (and should) get this in the paintComponent method by calling: g.getClipBounds() // I think, without checking the API. should return Rectangle end only repaint that portion of the component. Hope this helps you. ========================================================================== TOPIC: Visual Modelling Tool http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/c3aab05fc2bb074a ========================================================================== == 1 of 1 == Date: Wed, Sep 22 2004 9:44 pm From: IchBin <[EMAIL PROTECTED]> Edward H.

I also found a different completely free version that does all that with full functionally. It has small memory footprint. It is free! I heard about it from these java newsgroups.

Can you define your definition of "perfectly", related to your question ?

HTML is more lenient than XHTML, and browsers even more so. For instance, the EMBED element is an abomination unto W3C, since it doesn't have a restricted set of possible attributes. The easiest is probably to lowercase all element and attribute names, and change <empty> elements into <empty/> and hope for the best. ========================================================================== TOPIC: About Google Api http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/e584eaa8642abf4d ========================================================================== == 1 of 2 == Date: Wed, Sep 22 2004 11:07 pm From: wangyin <[EMAIL PROTECTED]> hi all: Where do I get com.google.soap.search.*? thanx! == 2 of 2 == Date: Thurs, Sep 23 2004 12:15 am From: Digby <[EMAIL PROTECTED]> http://www.google.com/apis/ wangyin wrote: > hi all: > Where do I get com.google.soap.search.*? > thanx! ========================================================================== TOPIC: version -> speed? http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/a63fd0f945fa2e4f ========================================================================== == 1 of 1 == Date: Wed, Sep 22 2004 11:31 pm From: [EMAIL PROTECTED] (Peter) Hi Same java program, if i use jdk5.0 to compile it, it will run faster than compiled by 1.4.2? thanks from Peter ([EMAIL PROTECTED]) ========================================================================== TOPIC: Error during a POST to a servlet in weblogic http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/c7fd3d60da3f6ed5 ========================================================================== == 1 of 1 == Date: Wed, Sep 22 2004 11:40 pm From: Frederic Houbie <[EMAIL PROTECTED]> Hi, I have a problem with Weblogic 8.1.

Nigel was assuming that it is a custom class that you wrote. Since you mention the java.net.Socket class, does your code by any chance read : Socket smtpSocket = new Socket(smtpServerVal, 25); ^^^^^^ instead ? (where smtpServerVal is the variable that holds the name) > > There is a firewall, but its the same for the windows machine too, so why would the > firewall on the solaris box cause such a big delay? > How can I check whether the DNS is working correctly on the machine? > > Is there a resolution? Since you say this happens only when you type names instead of an IP address, first thing one would suspect is a DNS resolution delay (though I can't really understand why it would fail "yahoo" quickly and "yahoo.com" after a delay - a smart resolver that understands invalid TLDs ???). It is possible that DNS is not setup properly on the Solaris machine ? Try running nslookup (or dig) from the commandline on the machine and see if similar delays occur. And if the name resolution fails on even well known domain names (like say yahoo.com) ask your system administrator to set the DNS right. (And if *you* have it to do it yourselves, make sure there is a "dns" entry in /etc/nssswitch.conf and that "nameserver" entries in the /etc/resolv.conf point to working DNS servers) BK ========================================================================== TOPIC: newbie RMI User http://groups-beta.google.com/group/comp.lang.java.programmer/browse_thread/thread/af49b3bdfce876e4 ========================================================================== == 1 of 2 == Date: Thurs, Sep 23 2004 12:09 am From: "paul.foreman" <[EMAIL PROTECTED]> Andrew, Just to let you know that I have got the applet working now.
