  • What is the best way to double buffer in this case and how to do it....

    currently I have
    public class Frame1 extends JFrame{
    //inside this class I call up circle class, rectangle class, etc.... to draw
    }I am making a "paint" program, and I have individual classes to handle the paint methods heres an example:
    abstract public class Shape {
        public Shape() {
        public abstract void draw(Graphics g, Color c, int x, int y, int width,int height);
    }and then....
    public class Circle extends Shape{
        public Circle() {
        public void draw(Graphics g, Color c, int oldx, int oldy, int newx, int newy) {
            g.setColor(c);
            g.drawOval(Math.min(oldx, newx), Math.min(oldy, newy), Math.abs(oldx - newx), Math.abs(oldy - newy));
    }There is also a Rectangle class, line class.... etc! So my question to you is the following... what is the best way to implement double buffer in the individual classes? And how to do it?? And also.... the drawings should be kept inside a jPanel.
    Any bit of help is much appreciated Thank you!!

    You don't need to do double-buffering. Swing
    components are double-buffered by default. Just make
    sure you override paintComponent() and not paint().
    And even if you had to, why would there be any
    difference in implementation for your classes whether
    they paint to on- or off-screen graphics?I need to override paintComponent()? what if I don't...
    I am using JBuilder2005 and they automate somethings for me. So thats how they did it when they created the application they did this....
    public class Frame1 extends JFrame{

        boolean packFrame = false;
         * Construct and show the application.
        public Application1() {

            // Validate frames that have preset sizes
            // Pack frames that have useful preferred size info, e.g. from their layout
            if (packFrame) {
                frame.pack();
            } else {
                frame.validate();
            // Center the window
            Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
            Dimension frameSize = frame.getSize();
            if (frameSize.height > screenSize.height) {
                frameSize.height = screenSize.height;
            if (frameSize.width > screenSize.width) {
                frameSize.width = screenSize.width;
            frame.setLocation((screenSize.width - frameSize.width) / 2,
                              (screenSize.height - frameSize.height) / 2);
            frame.setVisible(true);

  • What is the best way to back-up my entire library, and How??

    I need to back up my library before somethings happens!!  What is the best way to do that?  Also how do you restore it back on your itunes???

    My 2 cents...
    Fast backup for iTunes library  (Windows)
    Grab SyncToy  2.1, a free tool from MS. This can be used to copy your entire iTunes library (& other important data folders) onto another hard drive or network share. You can then use SyncToy periodically to synchronise or echo your library to the backup. A preview will show which files need to be updated giving you a chance to spot unexpected changes and during the run only the new or updated files will be copied saving lots of time.
    If your media is all organised below the main iTunes folder then you should also be able to open the backup library on any system running the same version of iTunes, regardless of the drive letter or path it appears on.
    Step-by-step install guide
    You restore files simply by copying them back to where they are missing from, or copy back the entire folder in the event of a major disaster.

  • What is the function name of "on mouse over tab focus" and how to disable this function?

    I can only find addons makes this function enable but not disable

    Tab preview is an Add-on that is installed for Firefox. You can manage your add-ons by going to Firefox> Tools > Add-ons. Look through what you have installed, and disable or remove any add-on that you no longer want. That should take care of the problem.

  • I connected my iphone 3g to itunes which was in 4.1 firmware and itunes ask for an update which i downloaded an updated the phone to version 6.1.3 but my phone cannot start it shows no service my sim card is not getting network and i cannot use the phone.

    i connected my iphone 3g to itunes which was in 4.1 firmware and itunes ask for an update which i downloaded an updated the phone to version 6.1.3 but my phone cannot start it shows no service my sim card is not getting network and i cannot use the phone. what should i do.?

    First, you do not have a 3G if you could upgrade it to 6.1.3, because 4.2.1 is the last version that will work on the 3G. So you either have a 3GS or you somehow hacked the phone to install an incompatible version. You can check the model you have by entering your serial number here: https://selfsolve.apple.com/agreementWarrantyDynamic.do
    Assuming you have a 3GS the most likely reason for your problem is you have a gray market phone that was hacked or jailbroken to unlock it. When you upgraded it you removed the hack, so the phone is now locked to its original carrier.

  • I bought Ebey NEW Boxed (NEVER OPENED) 16GB Black Iphone 5 Virgin Mobile (USA) NO CONTRACT, want to use it in Europe, particularly in Ukraine, but for some reason now my phone does not see the Ukrainian GSM sim card.

    I bought Ebey NEW Boxed (NEVER OPENED) 16GB Black Iphone 5 Virgin Mobile (USA) NO CONTRACT, want to use it in Europe, particularly in Ukraine, but for some reason now my phone does not see the Ukrainian GSM sim card. Please help to solve this problem. 

    Return it and get your money back. Virgin does not offer official unlocking, thus there's no way to get the phone officially unlocked for you to use it.
    Sorry, but you wasted your money.

  • Can I use the same GSM sim card from my 4s with the iphone 5?

    I'm from the Bahamas and I wanted to know if I can still use my same GSM sim card in the new iphone 5, do the iphone 5 GSM sim cards have to get cut smaller like they did with the iphone 4s sim cards???

    If there is no other option, you can cut the old SIM and rub it down to make it thinner, but be prepared for it not to work and the SIM ruined..

  • What is the use of lookup tranformation in odi

    Hi Experts,
    What is the use of lookup transformation in ODI.
    In ODI we use different kinds of joins, so my doubt is what is the difference between lookup transformation joins and normal joins we use in ODI.
    Please let me know with your valueable information.
    Thx,

  • Can I take my SIM Card out of my 3GS and insert it in another 3GS?   My daughter dropped my phone in the toilet tonight.   Can I take my SIM card that I've removed and simply put it in another 3GS phone (a relative's old phone) and it work?

    My 4 year old daughter dropped my 3GS in the toilet tonight.  Otterboxes are not waterproof in case you were wondering. : /   
    While my turned off phone is buried in a bag of rice, is it possible that I can take the now removed SIM card and put it in another 3GS for the interim?  I have an other 3GS (my mom's old one that we use as an iTouch for the kids) on hand that is attached to my apple ID.
    If this is possible, is it as simple as taking out the SIM card in my mom's old phone and replacing it with mine?   And does this mess anything up when / if I'm able to salvage my toilet phone?   Can I take the SIM card and simply put it back in my phone after having used it in the other one?
    Thanks.

    Put the SIM in the other phone and Restore it from Backup in iTunes. If the old one revives reverse the process.

  • What is a GSM-compatible SIM card and where do I get one?

    I live inMexico and plan to buy an unlocked iPhone5s in the States this summer.  What is a GSM-compatible SIM card and where do I get one? 

    I believe all cell phone carriers in Mexico are GSM carriers.
    Will this be your first cell phone?
    If not and your carrier in Mexico provides a nano-SIM card which is required for the iPhone 5S, you ask your carrier for the SIM card.
    If a problem develops with the iPhone that requires an exchange under warranty, you will need to return to the U.S. to receive an exchange.
