I just want to know how to do a new frame via typing a specific character then if you click the Jbutton, all the information (of that character) will pop up - for example a picture or a text.
For example, if I type the word "Dog", a picture of a dog and the information about it will pop out on a new window. Is this possible without database?
I want to do it without a database if it's possible.

It is possible to write a program without database but you have to think about a way to store the data. For database concern, I guess you mean how to store the code and picture of these dogs.
Yes, we can do that without database, but you need to write different logic i.e. hard coding like based on the condition
Example: After getting the data from the text field
String a=xx.getText().toString().trim();if(a.equals("dog"))
{
//call the iframe which u need
}
Note: As you need to store all the images in your working directory, or store all the frames with different names which includes images and information regarding the image and call them according to your requirement.

I am attempting to make a "sentence randomizer" that, when a button is pressed, makes a grammatically correct sentence, that may not make any sense, by looping different types of words from a separate folder and separate files. It also alternates colors in each panel. I so far am able to get the JButton to show up, but I can't seem to figure out how to get the panels to appear? Here is my code so far for the UI:
package user_interface;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Component;
import java.awt.Font;
import java.util.ArrayList;
import javax.swing.BorderFactory;
import javax.swing.BoxLayout;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import code.sentence;
import user_interface.RandomButtonListener;
public class sentenceUI {
private sentence _s;
private JButton _rando;
public sentenceUI() {
_s = new sentence(this);
JFrame f = new JFrame("Ryan Ellis' Lab 9");
f.setLayout(new BoxLayout(f.getContentPane(), BoxLayout.Y_AXIS));
JPanel topPanel = new JPanel();
f.add(topPanel);
JPanel lowerPanel = new JPanel();
f.add(lowerPanel);
_rando = new JButton("Random Sentence");
_rando.addActionListener(new RandomButtonListener(_s, this));
lowerPanel.add(_rando);
Color c1 = Color.BLUE;
Color c2 = new Color( 255 - c1.getRed(), 255 - c1.getGreen(), 255 - c1.getBlue());
for(int i = 0; i < 8; i++){
JLabel _l = new JLabel();
_l.setBackground(c1);
_l.setForeground(c2);
Color temp = c1;
c1 = c2;
c2 = temp;
_l.setBorder(BorderFactory.createEmptyBorder(0,0,8,5));
_l.setFont(new Font("Comic Sans", Font.BOLD, 18));
topPanel.add(_l);
}
ArrayList<String> _slst = new ArrayList<String>();
_slst.add("WordLists/adjectives.txt");
_slst.add("WordLists/adverbs.txt");
_slst.add("WordLists/determiners.txt");
_slst.add("WordLists/nouns.txt");
_slst.add("WordLists/verbs.txt");
ArrayList<ArrayList<String>> list = new ArrayList<ArrayList<String>>();
list.add(_slst);
int i = 0;
list.get(i % 5);
f.add(topPanel, BorderLayout.PAGE_START);
f.add(lowerPanel, BorderLayout.PAGE_END);
f.setVisible(true);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.pack();
}
private void createRButton(String string, JPanel lowerPanel) {
createRButton("Random", lowerPanel);
}
You're adding topPanel twice to the JFrame, here
JPanel topPanel = new JPanel();
f.add(topPanel);
and here:
f.add(topPanel, BorderLayout.PAGE_START);
f.add(lowerPanel, BorderLayout.PAGE_END);
and in the 2nd addition, you're adding it as if the JFrame currently used a BorderLayout, but it's not since you've given it a BoxLayout.
Instead, only add the topPanel once, and in a logical way. Also consider giving your JLabel's some dummy text, such as " " so that they have some size when you first pack() your GUI.
Also, your labels are being added but they have no size and are non-opaque and so can't be seen. For example try this within your for loop to see for yourself:
JLabel _l = new JLabel("Label " + i); // to give labels size
_l.setOpaque(true); // so you can see the background color
_l.setBackground(c1);
_l.setForeground(c2);
I have been trying to make a program where data inputted into a JTextArea, would then be counted and then displayed on a JLabel the number of words, after a button is clicked.
However the code I have tried to use, just shows the value of 1 everytime.
Any idea why?

}

gc.gridx = 0;
gc.gridy = 0;
add(title,gc);
gc.gridx = 0;
gc.gridy = 1;
add(scrollPane, gc);
}
}
Just to put it in context, my JTextArea is on a seperate panel / class to the panel containing the button and JLabel.
Every time I run the program and click the button, after inputting some words the value is always one even if the text box is empty.
Well, if you create a new TextAPanel and assign it to the textPanel variable - then when you try to get input you get nothing, because the newly created panel doesn't contain anything. If textPanel is a field in your class, you should just remove the textPanel = new TextAPanel(); line and it should work fine. If you get a NullPointerException, it means you forgot to initialize it earlier in the code, you should probably do it in the constructor.
EDIT: OK, I made it work, the code is below. I have no idea how your program compiled, because in your TextAPanel class you had TextAreaPanel() method/constructor, which caused compilation error in my Eclipse. Anyway, I got this working, you'll need to complete it, but this should get you started:
import java.awt.event.*;
import javax.swing.*;
import java.awt.*;

For that purposes you need to use anchor and weighty properties of GridBagConstraints.
In next example I set JTextField to the south:
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class Example extends JFrame {
public Example (){
JTextField f = new JTextField(20);
setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
c.anchor = GridBagConstraints.SOUTHEAST;
c.weighty = 1;
add(f,c);
}
public static void main(String...strings ){
Example e = new Example();
e.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
e.pack();
e.setLocationRelativeTo(null);
e.setVisible(true);
}
}
If you need to fill all horizontal space by component add next :
c.weightx = 1;
c.fill = GridBagConstraints.HORIZONTAL;
For Image you can use JLabel instead of JTextField in my example :
JLabel l = new JLabel(new ImageIcon(getClass().getResource(PATH_TO_IMAGE)));
You cannot add an image directly to a JPanel. What you can do instead is to set the image to be the image icon of a JPanel or JLabel and add that to whatever you're trying to make.
I've managed to get the JButton buttonOne in class Database to switch panels, but at the same time it's opening a new JFrame to do this. How can I change it so it just changes the JFrame panel without having to open another JFrame? I have a feeling I could do this if I could return both JPanel and JFrame but I don't know how to do so. Thanks for any help :

try {

gbc.anchor = GridBagConstraints.PAGE_END;
SQLsPanel.add(buttonOne, gbc);
buttonOne.setBorder(BorderFactory.createEmptyBorder());
buttonOne.setContentAreaFilled(false);
return SQLsPanel;
}
}
Try the following:
final JFrame frame = new JFrame("Lohn Jocke and the Quest for Qualia"); //Had to set frame to final for the action listener
final String name = frame.getName();
Add the variable 'name' just below where you declare the JFrame.
// JFrame settings
frame.add(panel);
frame.getContentPane().add(BorderLayout.CENTER, panel);
frame.setSize(860,500);
frame.setLocationRelativeTo(null);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setResizable(false);
frame.setVisible(true);
if(Frame.getFrames().length > 1){
Frame[] f = Frame.getFrames();
for(Frame frames : f){
if(!frames.getName().equals(name)){
frames.dispose();
}
}
}
Add this below where you set the JFrame settings.
what happens is when you call this
MainMenu passme = new MainMenu();
From the InstructionsPanel you are creating a new JFrame from your class constructor in addition to the current frame you already have(Hence why you end up with 2). what I have tried to do is get the name of your new Frame you are creating(with the name variable), then using the loop at the bottom wipe all other Frames away leaving you with the new one with which to display your Panel.(Frame.getFrames() returns a list of all frames, I then iterate over removing all the ones that aren't needed)
You may want to tweak it if you add more JFrames in future but hopefully this will be somewhat effective for you for now at least.(i have tried to replicate your code with dummy images to grasp at the problem for this 'fix' so apologies if I have misunderstood the issue here )
Hope this helps.
I am wondering about this since we are making a game in Swing and we made our map tiles into jButtons instead of jPanels for whatever reason. Now we want to put units on top of them so the map background is still shown when the unit is on top of them. Anyone know if this is possible?
OK, so I am not sure this is really what you are looking for and how your application is currently set up, but this is an example to have JButtons on top of each other (if this is not what you are looking for, consider posting an SSCCE and give more details). There are other alternatives and better way to handle such thing, but since you asked JButton over a JButton, here is a snippet showing that:

It might be a better idea to have a panel which contains buttons. Your panel could then use a mouse event listener to perform an action when clicked on.
The advantage of using a jPanel is that you can set a layout within it, which will make positioning your buttons in it much easier.
Well it is possible to put a JButton Over an other JButton you just wont be able to see it.
CardLayout cl = new CardLayout();
JPanel jpnlMain = new JPanel(cl);
jpnlMain.add(new JButton(), "FIRST");
jpnlMain.add(new JButton(), "SECOND");
Then Maybe you could create a Class that Extends Either the Cardlayout or the JPanel to make it show both Items.
EDIT
Made a little Test and HJere is a Button in a Button Buttonception!!
Main class:
import javax.swing.JFrame;
public class Test {
public static void main(String[] arg0){
SpecialButton sp = new SpecialButton();
JFrame jf = new JFrame();
jf.add(sp);
jf.setVisible(true);
jf.pack();
}
}
Special Button Class:
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JPanel;
public class SpecialButton extends JButton{
SpecialButton(){
super();
JButton jbtnMid = new JButton();
JLabel jlblMid = new JLabel(new ImageIcon(this.getClass().getResource("/Images/arrowUpIcon.png")));
jbtnMid .add(jlblMid);
this.add(jbtnMid);
this.setVisible(true);
}
}
