Placing buttons on top of a rectangle..

I have 5 button that i placed on my applet by specifying its exact location
by using setBounds...for example, i have...
btnOne.setBounds(15,159,120,40)...etc.
I want to place these five buttons on top of a black rectangle, so that the
black rectangle is serves as a background. How can I do this in Java? I also,
wanted to place text over an image i have in my applet but am experience
problems.
thanx

You can put the buttons in a panel and set the background color of the panel to black. Then you just have to add the panel to your applet.

Problem placing buttons on top of a background image

My knowledge of Java isn't the greatest and I am currently having problems placing buttons on top of a background image within a JApplet (this is also my first encounter with Applets).
I'm using a Card Layout in order to display a series of different screens upon request.
The first card is used as a Splash Screen which is displayed for 5 seconds before changing to the Main Menu card.
When the Main Menu card is called the background image is not shown but the button is.
While the Applet is running no errors are shown in the console.
Full source code can be seen below;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.net.*;

1) When posting here, please use fewer comments. The comments that you have don't help folks who know Java read and understand your program and in fact hinder this ability, which makes it less likely that someone will in fact read your code and help you -- something you definitely don't want to have happen! Instead, strive to make your variable and method names as logical and self-commenting as possible, and use comments judiciously and a bit more sparingly.
2) Try to use more methods and even classes to "divide and conquer".
3) To create a panel with a background image that can hold buttons and such, you should create an object that overrides JPanel and has a paintComponent override method within it that draws your image using the graphics object's drawImage(...) method
For instance:
an image jpanel:
import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.JButton;
import javax.swing.JPanel;
public class BackgroundImage
    // **** this will have to be changed for your program:
    private static final String IMAGE_PATH = "../../m02/a/images/Forest.jpg";
    private BufferedImage myImage = null;
    private JPanel imagePanel = new JPanel()
        @Override
        protected void paintComponent(Graphics g)
        {   // *** here is where I draw my image
            super.paintComponent(g); // **** don't forget this!
            if (myImage != null)
                g.drawImage(myImage, 0, 0, this);
    public BackgroundImage()
        imagePanel.setPreferredSize(new Dimension(600, 450));
        imagePanel.add(new JButton("Foobars Rule!"));
        try
            myImage = createImage(IMAGE_PATH);
        catch (IOException e)
            e.printStackTrace();
        catch (URISyntaxException e)
            e.printStackTrace();
    private BufferedImage createImage(String path) throws IOException,
            URISyntaxException
        URL imageURL = getClass().getResource(path);
        if (imageURL != null)
            return ImageIO.read(new File(imageURL.toURI()));
        else
            return null;
    public JPanel getImagePanel()
        return imagePanel;
}and an applet that uses it:
import java.lang.reflect.InvocationTargetException;
import javax.swing.JApplet;
import javax.swing.SwingUtilities;
public class BackgrndImageApplet extends JApplet
    @Override
    public void init()
        try
            SwingUtilities.invokeAndWait(new Runnable()
                @Override
                public void run()
                    getContentPane().add(new BackgroundImage().getImagePanel());
        catch (InterruptedException e)
            e.printStackTrace();
        catch (InvocationTargetException e)
            e.printStackTrace();

Button On Top Of Drop Zone

i am building an menu in DVDSP, and im creating drop zones, but i want the outside to be highlighted around it. as in, i want the outer edge ring of the video to change colors as selected. so i created the button, and created the drop zone in front of it. when i go to the simulator, the button is on top, completely covering my drop zone video. is there any way to change this?
ive already tried bringing it forward. when i make the drop zone bigger, i can see it outside of the button.

For example: I have a movie placed in my article. And on top of the movie I want to place a button. The "mask/dummy overlay" function isn't working because the button will lose his function. Is there an other way to place a button on top of an interactive element?

This part of tabbed pane is not customizable as it lies in the ComponentUI(TabbedpaneUI) portion of the tabbedpane.
But I can point out the place u can change to bring the desired feature into effect.
U can find an Inner class called ScrollableTabSupport
Look for the methods createButtons where u can create extra buttons and add to the tabbed pane.
The Inner class also implements actionListener where u can implement the action for the button u added.
By this method U have to use your own extended TabbedPaneUI which u cant escape from.
Hope this will help u.

Follow these steps to log into your iCloud account on your computer and deactivate "Find my iPhone" on your device:
Remove an iOS device or Mac on which you can’t turn off Find My iPhone
If you can’t turn off Find My iPhone on the device, turn off the device so it goes offline, then remove it from Find My iPhone on iCloud.com.
Note: You can also remove your iOS device by first erasing it—just follow the instructions below for removing an iOS device you don’t have. You can later restore the device from an iCloud or iTunes backup.
Turn off the device you want to remove.
Sign in to icloud.com/#find on another computer with your Apple ID (the one you use with iCloud). If you’re using another iCloud app, click the app’s name at the top of the iCloud.com window, then click Find My iPhone.
Click All Devices, select the offline device, then click Remove from Account. If you don’t see Remove from Account, click All Devices again, then click the Delete button next to the device. If the device comes online again, it will reappear in Find My iPhone. If your device reappears, turn off Find My iPhone on the device (follow the instructions above for removing a device by turning off Find My iPhone), or if it’s an iOS device and you no longer have it, follow the instructions below for removing an iOS device you no longer have.
Remove an iOS device you no longer have
If you no longer have the iOS device because you gave it away or sold it, you need to remotely erase it before you can remove it.
Sign in to icloud.com/#find with your Apple ID (the one you use with iCloud). If you’re using another iCloud app, click the app’s name at the top of the iCloud.com window, then click Find My iPhone.
Click All Devices, then select the device.
Click Erase [device], then enter your Apple ID password. Because the device isn’t lost, don’t enter a phone number or message.
Note: If you’re trying to erase a family member’s device, that person will need to enter his or her Apple ID password on this device. If the device is offline, the remote erase begins the next time it’s online. You’ll receive an email when the device is erased.
When the device is erased, click Remove from Account.All your content is erased, and someone else can now activate the device.

Disabled
Place the iOS device in Recovery Mode and then connect to your computer and restore via iTunes. The iPod will be erased.
iOS: Wrong passcode results in red disabled screen
If recovery mode does not work try DFU mode.
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
For how to restore:
iTunes: Restoring iOS software
To restore from backup see:
iOS: How to back up
If you restore from iCloud backup the apps will be automatically downloaded. If you restore from iTunes backup the apps and music have to be in the iTunes library since synced media like apps and music are not included in the backup of the iOS device that iTunes makes.
You can redownload most iTunes purchases by:
Downloading past purchases from the App Store, iBookstore, and iTunes Store

My lock button on top of my iphone 4 is completely stuck down. Also, my iphone completely shut off and will not turn back on and is nonresponsive to a charger. Is there a way I can revive it? Is there a way I can get my pictures and videos off of it?

Please help me!!! The lock button on top of my Iphone 4 is pushed down completely and is stuck! And then yesterday I looked down and my iphone was completely black. It would not turn on seeing as how I could not push the top button to reset it to turn back on and then also it would not respond to a charge. I was wondering if anyone could suggest anything at all in how to turn it back on and bring it back to life and if there was any way I could save my photos and such off there! Thank you!!

Any help MUCH appreciated!!... I cannot seem to figure out how i've lost my close, minimize and resize buttons in top left. IT's only in Illustrator. I have a MacBook Pro..
Any thoughts???
Thanks,

Chances are the buttons are merely behind the Control Panel or your'e simply in Full Screen Mode.
If your document is behind the Control panel, tap the Tab key to hide all panel, then move the document down so it's not behind the control panel.
If you are in Full Screen Mode, tap the F key on the keyboard until you see the buttons again.

My little scroll button on top of my older model A1197 mouse.

My little scroll button on top of my older model A1197 mouse works only intermittantly and usually, if at all, only in one direction. ??

This is usually caused by debris building up between the rollerball and the rollers underneath. Sometimes you can free this up by turning the mouse upside down and rubbing the rollerball vigorously on a sheet of paper.
