JTextField textbox1;
textbox1 = new JTextField();
textbox1.setBounds((549+x),(61+y),295,17);
textbox1.setOpaque(false);
Main.panel.add(textbox1);
I need a Textbox on top of an image to show the image underneath but still be able to be typed in. I've tried using the textbox1.setOpaque(false) method but it didn't change anything and didn't throw and error. Sorry if i didn't format the code properly I tried but I just don't use this site very often.
set only the background of the text box to transparent
setBackground(new Color(0,0,0,0));
Use
setOpaque(false);
Only when your text field has child components inside the textfield you want to make visible but not the textfield itself to avoid artifacts
The following example has a text field over a red circle.
import javax.swing.*;
import java.awt.*;
public class JunkStop{
public static void main(String[] args){
JFrame frame = new JFrame("wakka");
JPanel layout = new JPanel(null);
JPanel background = new JPanel(){
public void paintComponent(Graphics g){
super.paintComponent(g);
g.setColor(Color.RED);
g.fillOval(100, 100, 200, 200);
}
};
background.setOpaque(false);
JTextField field = new JTextField("testing");
field.setBackground( new Color(0, 0, 0, 0) );
layout.add(field);
layout.add(background);
field.setSize(new Dimension(200, 20));
field.setBounds(100, 150, 200, 20);
background.setBounds(0, 0, 400, 400);
frame.setContentPane(layout);
frame.setVisible(true);
frame.setSize(400, 400);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

So i am trying to make a Menu for a game i am working on.
I want to put an image as background at my menuPanel but i cant figure out how to let the image rescale every time i am raising the window. I have made a JLabel and i have imported an image from my main method and when i launch the game i can see that the image is correctly imported but i want to fill up all menuPanel and also stretch as i am raising the window to full screen or decreasing to the Minimum size of my frame.
How can i do that?
As you can see at the screenshot i want the text to be on top of the image and the image as a background and full screen.

Swing is based on parent/child relationships.
So if you want the button displayed on the background the structure of your code needs to be:
- frame
- background component
- buttons panel
The easiest way to do this is to use a JLabel with your image as the background. Then you add the buttons panel to the label. The only issue is that by default a JLabel doesn't use a layout manager so you need to see the layout manager to achieve your desired effect.
I would suggest using a GridBagLayout, then the buttons will be centered on the panel. The basic code would be:
JPanel buttons = new JPanel();
buttons.add(...);
JLabel background = new JLabel(...);
background.setLayout( new GridBagLayout() );
background.add(buttons, new GridBagConstraints());
The label will be displayed at the size of the background image.
If you want the background image to scale as the frame size changes, then you have a couple of options:
Use the Stretch Icon. It will automatically scale the image to the space available.
Replace the JLabel with a JPanel and paint the image yourself. Check out the Background Panel which can be configured to automatically scale an image.
Edit:
i tried reading the code and its really confusing.
Well, the intent was not for you to read the code. The intent was for you to use the code.
When you program you learn how to use classes and the methods of the class. When you use the ImageIcon class did you read the code first or just learn how to use its contructor?
Now I agree, the two classes don't have a published API but you really only need to understand the constructors and methods of the classes in order to use them.
If you read the Stretch Icon blog it states:
StretchIcon is a drop-in replacement for ImageIcon, which it extends, except that ImageIcon’s no-arg constructor isn’t supported.
So that means that if you would normally use:
JLabel background = new JLabel( new ImageIcon("background.jpg") );
you would use the following for the StretchIcon:
JLabel background = new JLabel( new StretchIcon("background.jpg") );
Similarly for the BackgroundPanel, if you read the blog it states that it is:
an extension of JPanel that provides some custom painting support for the drawing of images
It then goes on to say that the default is to paint the image "scaled" which is what you want. So all you need to figure out is which constuctor to use to create the panel.
For a regular panel you would use:
JPanel background = new JPanel();
For the BackgroundPanel the simplest constructor to use would be the first constructor of the class which simply takes an Image as a parameter:
JPanel background = new BackgroundPanel(image);
Now you have a panel and you simply add your 3 buttons to the panel.
I did not write the StretchIcon class so I don't know the details of the code, and I don't care about the details as long as the class does what I expect it to do.
I did write the BackgroundPanel class so if you has specific questions then I can probably help you. But I don't have time to guess which part of the code you find confusing.
Edit 2:
I have 3 buttons and i want them to be at the cemter and stretch too so they stay at the center of the image
This is about learning how to use layout managers. I never use an IDE to generate my code. I want full control over the code. This allows your code to be cleaner an more easily maintained.
This allows you to choose the appropriate layout manager for the job and allows you to easily nest panels with different layout mangers. In this case you want to use the GridBagLayout which by default will center horizontally and vertically any component added to it.
By default the BackgroundPanel uses a BorderLayout. But you can easily change it to use the GridBagLayout. Then I would use a second panel with a GridLayout for the buttons.
So the code would be something like:
JPanel buttonPanel = new JPanel( new GridLayout(0, 1, 10, 0) );
buttonPanel.add(playBtn);
...
backgroundPanel.add(buttonPanel, new GridBagConstraints());
Now as the frame size is changed the buttons will automatically re-center.
Read the section from the Swing tutorial on Layout Managers for more information and examples.
Keep a link to the Swing tutorial handy. It contains information and example of most Swing basics.
You could use the method paintComponent(Graphics g) and drawImage() from JPanel to draw your Image.
import java.awt.*;
import java.io.*;
import javax.imageio.ImageIO;
import javax.swing.*;
public class AutoScale extends JFrame{
private Image image;
public AutoScale() {
setTitle("AutoScale");
setResizable(true);
setSize(400,400);
try {
image = ImageIO.read(new File("path to your file"));
}catch(IOException e) {
System.out.println("Image not found");
}
JPanel panelImg = new JPanel() {
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 30, 30, getWidth()/2, getHeight()/2, null);
}
};
add(panelImg);
}
public static void main(String[] args) {
AutoScale frame = new AutoScale();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
}
In this example, I create the Panel and paintComponent(). Inside that method, I invoke drawImage() with 6 parameters:
The Image
x Coordinate
y Coordinate
The width of the Frame divided by 2(you can play with the size of your image by adding, substracting or dividing the result of
getWidth())
The height of the Frame divided by 2(same as the width)
The imageObserver, which generally is set to null.
The paintComponent() method gets invoke automatically whenever the size of the Panel changes, so there's no need to use a WindowListener as I suggested earlier.
Note: I use a try-catch block because if it can't find the file, it will throw an Exception.
Hope this was helpful!
When I run the below code, I am unable to see the background color as red. It's showing default one. Is there anything that I have to add to these lines?
import java.awt.*;
import java.awt.Graphics;
import javax.swing.*;
public class gfix extends JPanel {
#Override
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.setColor(Color.red);
g.fillRect(80, 100, 150, 75);
}
public static void main(String[] args){
gfix gg=new gfix();
JFrame frame = new JFrame("RISK");
frame.setSize(800, 600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
panel.setLayout(null);
frame.add(panel);
JButton button = new JButton("test");
button.setBounds(100, 100, 150, 150);
panel.add(button);
frame.setVisible(true);
}
}
Your are overriding painGraphics() in gfix class so add gfix class object into your frame not Java provided JPanel class object.
gfix gg=new gfix();
JFrame frame = new JFrame("RISK");
frame.setSize(800, 600);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//JPanel panel = new JPanel(); Not needed
//panel.setLayout(null);
frame.add(gg);
JButton button = new JButton("test");
button.setBounds(100, 100, 150, 150);
gg.add(button);
frame.setVisible(true);
for g.fillRect(80, 100, 150, 75); give proper panel bounds to fill complete panel background. OR use int width = getWidth();
int height = getHeight(); in paintGraphics to get actual height and width.
import java.awt.*;
import javax.swing.*;
import javax.swing.border.EmptyBorder;
public class gfix {
public static void main(String[] args) {
JFrame frame = new JFrame("RISK");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
panel.setBackground(Color.RED);
frame.add(panel);
JButton button = new JButton("test");
// adjust numbers as needed
button.setMargin(new Insets(20,40,20,40));
panel.add(button);
// adjust numbers as needed
panel.setBorder(new EmptyBorder(10,40,50,200));
frame.pack();
frame.setVisible(true);
}
}
Other tips:
Java GUIs have to work on different OS', screen size, screen resolution etc. using different PLAFs in different locales. As such, they are not conducive to pixel perfect layout. Instead use layout managers, or combinations of them along with layout padding and borders for white space.
Provide ASCII art or a simple drawing of the intended layout of the GUI at minimum size, and if resizable, with more width and height - to show how the extra space should be used.
Please learn common Java nomenclature (naming conventions - e.g. EachWordUpperCaseClass, firstWordLowerCaseMethod(), firstWordLowerCaseAttribute unless it is an UPPER_CASE_CONSTANT) and use it consistently.
I'm working on a log in server & my JTextFields aren't transparent when I set Opaque to false.
My code:
//username
JTextField jUsername = new JTextField(10);
jUsername.setBounds(520, 284, 190, 25);
jUsername.setOpaque(false);
jUsername.setBorder(null);
getContentPane().add(jUsername);
//password
JTextField jPassword = new JTextField(15);
jPassword.setBounds(520, 374, 190, 25);
jPassword.setOpaque(false);
jPassword.setBorder(null);
//jPassword.setBackground(new Color(Color.TRANSLUCENT));
getContentPane().add(jPassword);
An Image what is still happening:
Anyone ever seen this before or know how to fix it? I've looked around but no one had the same problem as I do, & the fixes for theirs didn't work for mine. ( I Know I'm not using JPasswordField for password, that's temporary )
Basically, the UI delegate of the text field paints not only the text but also the field area (within the border) regardless of the opaque setting.
What you can do, is set the background color to a transparent value, something like new Color(0, 0, 0, 0) for example, which is fully transparent.
For example...
JTextField jUsername = new JTextField(10);
jUsername.setBounds(520, 284, 190, 25);
jUsername.setBackground(new Color(0, 0, 0, 0));
jUsername.setOpaque(false);
jUsername.setBorder(null);
getContentPane().add(jUsername);
//password
JTextField jPassword = new JTextField(15);
jPassword.setBounds(520, 374, 190, 25);
jPassword.setBackground(new Color(0, 0, 0, 0));
jPassword.setOpaque(false);
jPassword.setBorder(null);
//jPassword.setBackground(new Color(Color.TRANSLUCENT));
getContentPane().add(jPassword);
You can affect the transparency of a color by changing the last parameter, for example new Color(255, 255, 255, 128) would white, 50% transparent...
You may also wish to change the caret color, take a look at JTextComponent#setCaretColor for more details

I tried with another option and it worked for me.
You can modify the property Background of the textfield. Select the option custom code in the Selection Box and paste new Color(0, 0, 0, 0)in the txtField.setBackground property.
Then just change the border property to No border. and finally uncheck the opaque checkbox.
Here a capture of my netbeans interface
I am trying to add a JPanel (well, several) to a JLayeredPane. However, when I do so, the paint component method of the JPanel seems to have no effect. An example is included below:
import javax.swing.*;
import java.awt.*;
public class Example {
public static void main(String[] args) {
// This Works as expected
JFrame usingPanel = new JFrame();
JPanel p = new JPanel();
p.add(new BluePanel());
usingPanel.setContentPane(p);
usingPanel.pack();
usingPanel.setVisible(true);
// This makes the frame but does not paint the BluePanel
JFrame usingLayer = new JFrame();
JLayeredPane l = new JLayeredPane();
l.setPreferredSize(new Dimension(200,200));
l.add(new BluePanel(), JLayeredPane.DEFAULT_LAYER);
JPanel p2 = new JPanel();
p2.add(l);
usingLayer.setContentPane(p2);
usingLayer.pack();
usingLayer.setVisible(true);
}
static class BluePanel extends JPanel{
public BluePanel(){
setPreferredSize(new Dimension(200,200));
}
#Override
public void paintComponent(Graphics g){
super.paintComponent(g);
g.setColor(Color.BLUE);
g.fillRect(0, 0, 200, 200);
}
}
}
Why is this? and what are the possible solutions?
JLayeredPane does not have a LayoutManager, so you need to set the location and size of your panels yourself.
See the tutorial
you hardcoded the size on the screen and have to change from
g.fillRect(0, 0, 200, 200);
to
g.fillRect(0, 0, getWidth(), getHeight());
(a minor change) add the method
#Override
public Dimension getPreferredSize() {
return new Dimension(200, 200);
}
and then remove of code line setPreferredSize(new Dimension(200,200));
I am trying to fix a JFrame where there will be a background image and on the image JButtons which will do some commands. I try to do it without layout because i want to put small buttons in some specific locations on the JFrame but every time i do it, the background image comes to the front or the JFrame has size equal to the JFrame size. With the following code, the JButton has the same size to JFrame. I have tried to change the size and location of the JButton but nothing. Can you help me please?
here is the code
public final class Test extends JComponent
{
private Image background;
private JFrame frame;
private Dimension dimension;
public Test()
{
dimension = new Dimension(15, 15);
frame = new JFrame("Iphone");
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(this);
frame.setBounds(641, 0, 344, 655);
frame.setVisible(true);
test = displayButton("tigka");
frame.getContentPane().add(test);
}
public void update(Graphics g)
{
paint(g);
}
public void paintComponent(Graphics g)
{
super.paintComponents(g);
g.drawImage(background, 0, 25, null); // draw background
// label();
test = displayButton("test");
}
public JButton displayButton(String name)
{
JButton button = new JButton(name);
button.setSize(100, 100);
button.setPreferredSize(dimension);
return button;
}
You need to change the content pane to get a background for your Frame.
public static void main(String[] args) throws IOException {
JFrame frame = new JFrame("Test");
frame.setContentPane(new JPanel() {
BufferedImage image = ImageIO.read(new URL("http://upload.wikimedia.org/wikipedia/en/2/24/Lenna.png"));
public void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 0, 0, 300, 300, this);
}
});
frame.add(new JButton("Test Button"));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(300, 300);
frame.setVisible(true);
}
Output:
Have you tried using a JLabel with HTML in the label? Something like this:
import javax.swing.*;
public class SwingImage1
{
public static void main( String args[] )
{
JFrame frm = new JFrame( "Swing Image 1" );
JLabel lbl = new JLabel( "<html><body><img src=\"http://liv.liviutudor.com/images/liv.gif\"></body></html>" );
frm.getContentPane().add( lbl );
frm.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
frm.pack();
frm.setVisible( true );
}
}
then on top of your label you can add your button?
You should swap those two lines:
super.paintComponents(g); //paints the children, like the button
g.drawImage(background, 0, 25, null); // draw background later possibly overwriting the button
Thus it should be this order:
g.drawImage(background, 0, 25, null);
super.paintComponents(g);
Additionally, note that the content pane's default layout is BorderLayout. Thus you'd set the layout of your content pane to null explicitly.
