How to attach new JFrame to an already made frame? - java

How do I connect a frame to an existing frame?
The code below is the code for the appletframe. What I want to do is add the other code which is for the frame to be connected to the bottom of the AppletFrame, so that when I drag the Appletframe the frame code with we dragged with it as well. Basically I want the frame code to be attached with the appletFrame so that both the frames are together.
AppletFrame
appletFrame = new JFrame(Settings.serverName);
Loader.webclient = false;
appletFrame.setLayout(new BorderLayout());
appletFrame.setDefaultCloseOperation(3);
appletPanel.setLayout(new BorderLayout());
appletFrame.setIconImage(Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("/resources/icon.png")));
appletPanel.add(this);
appletPanel.setPreferredSize(new Dimension(767, 537));
appletFrame.getContentPane().add(appletPanel, "Center");
appletFrame.pack();
appletFrame.setLocationRelativeTo(null);
appletFrame.setVisible(true);
JMenuBar jmenubar = new JMenuBar();
appletFrame.setJMenuBar(jmenubar);
Layout = new FlowLayout();
ImageIcon keyboard = new ImageIcon(Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("/resources/keyboard.png")));
ImageIcon wrench = new ImageIcon(Toolkit.getDefaultToolkit().getImage(this.getClass().getResource("/resources/wrench.png")));
Button1 = new JButton("Vote");
Button2 = new JButton("Item List");
Button3 = new JButton("Screenshot");
Button4 = new JButton(wrench);
Button5 = new JButton(keyboard);
Button4.setBorder(null);
Button4.setBorderPainted(false);
Button4.setContentAreaFilled(false);
Button5.setBorder(null);
Button5.setBorderPainted(false);
Button5.setContentAreaFilled(false);
jmenubar.setLayout(Layout);
jmenubar.add(Button1);
jmenubar.add(Button2);
jmenubar.add(Button3);
jmenubar.add(Button4);
jmenubar.add(Button5);
Button1.addActionListener(this);
Button2.addActionListener(this);
Button3.addActionListener(this);
Button4.addActionListener(this);
Button5.addActionListener(this);
Button1.setText("Vote");
Button2.setText("Item List");
Button3.setText("Screenshot");
Frame which I want it to be attached with the AppletFrame. I want this to be attached to the bottom of the appletFrame, but I don't know how to do it.
JFrame frame = new JFrame();
frame.setSize(775,121);
frame.setResizable(false);
JTextArea textArea = new JTextArea("TEST");
textArea.setSize(400,400);
textArea.setLineWrap(true);
textArea.setEditable(false);
textArea.setVisible(true);
JScrollPane scroll = new JScrollPane (textArea);
scroll.setVerticalScrollBarPolicy (JScrollPane.VERTICAL_SCROLLBAR_ALWAYS);
scroll.setHorizontalScrollBarPolicy(JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
frame.add(scroll);
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

As I alluded to in my first comment, this GUI would be better combined into a single top-level container.
Here is an SSCCE1 (mentioned in my 2nd comment) that shows the basic idea, though now I have a better idea of the effect required, the JSplitPane seems less appropriate. Here I just combine the GUI elements into the same layout.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class TestGUI extends JPanel {
TestGUI() {
JFrame appletFrame = new JFrame("Settings.serverName");
appletFrame.setLayout(new BorderLayout());
appletFrame.setDefaultCloseOperation(3);
JPanel appletPanel = new JPanel(new BorderLayout());
appletPanel.add(this);
appletPanel.setPreferredSize(new Dimension(767, 537));
appletFrame.getContentPane().add(appletPanel, BorderLayout.CENTER);
// Don't use a menu-bar as a tool-bar!
JToolBar jmenubar = new JToolBar();
appletPanel.add(jmenubar, BorderLayout.PAGE_START);
JButton Button1 = new JButton("Vote");
JButton Button2 = new JButton("Item List");
JButton Button3 = new JButton("Screenshot");
JButton Button4 = new JButton("wrench");
JButton Button5 = new JButton("keyboard");
Button4.setBorder(null);
Button4.setBorderPainted(false);
Button4.setContentAreaFilled(false);
Button5.setBorder(null);
Button5.setBorderPainted(false);
Button5.setContentAreaFilled(false);
jmenubar.setLayout(new FlowLayout());
jmenubar.add(Button1);
jmenubar.add(Button2);
jmenubar.add(Button3);
jmenubar.add(Button4);
jmenubar.add(Button5);
JTextArea textArea = new JTextArea("TEST", 4, 65 );
textArea.setLineWrap(true);
textArea.setEditable(false);
textArea.setVisible(true);
JScrollPane scroll = new JScrollPane (
textArea,
JScrollPane.VERTICAL_SCROLLBAR_ALWAYS,
JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
appletPanel.add(scroll, BorderLayout.PAGE_END);
appletFrame.pack();
appletFrame.setLocationByPlatform(true);
appletFrame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater( new Runnable() {
public void run() {
new TestGUI();
}
});
}
}
And yes, this would have arrived sooner if I'd had an SSCCE to start with. ;)

Place label for text box above the box and not to the side

As stated in the title i need to move the label for the text box to be above the box and not to the side. attached i have a picutres of what i mean. what i have vs what i want i have tried searching for it but i cannot seem to find the answer im looking for/not exactly sure what to look up. I have tried using JFrame but it made a separate window unless i need to make the entire GUI a JFrame for me to get the result i want?
Also the actionPerformed method has things but it is irrelevant to the question but displays correctly still.

You can use a nested JPanel with another layout in order to achieve that. I would go with BorderLayout here. You can also other layouts that allow vertical orientation. Visiting the visual guide to Layout Managers will help you spot them.
JLabel name_label = new JLabel("Name on Order");
name.addActionListener(this);
JPanel verticalNestedPanel = new JPanel(new BorderLayout());
verticalNestedPanel.add(name_label, BorderLayout.PAGE_START);
verticalNestedPanel.add(name, BorderLayout.PAGE_END);
panel5.add(verticalNestedPanel);

Layout Managers with icon (gif)

Essentially, I am trying to add a home screen with 4 buttons, 3 difficulty buttons and a play button. I add the buttons to a JPanel and add the JPanel with a BoxLayout of Center. Why does the buttons still go all the way off to the right? Setting the icon for a JLabel on and adding it to the home screen JPanel is a possible mess up the flow of components? I want the difficulty buttons to be on top of the of the gif with the Play button at the bottom. Thanks for your help.
//container
snake = new JFrame();
snake.setLayout(new BorderLayout());
//home screen panel
homeScreen = new JPanel();
homeScreen.setLayout(new BoxLayout(homeScreen, BoxLayout.X_AXIS));
homeScreen.setPreferredSize(new Dimension(320, 320));
JLabel bg = new JLabel();
ImageIcon icon = new ImageIcon("HomeBG.gif");
icon.getImage().flush();
bg.setIcon(icon);
homeScreen.add(bg);
easy = new JButton("Easy");
medium = new JButton("Medium");
hard = new JButton("Hard");
play = new JButton("Play");
//button listeners code here
homeScreen.add(easy);
homeScreen.add(medium);
homeScreen.add(hard);
homeScreen.add(play);
snake.add(homeScreen, BorderLayout.CENTER);
snake.setTitle("Snake Game");
snake.pack();
snake.setVisible(true);
snake.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
You need to change your code as shown below.
snake = new JFrame();
snake.setLayout(new BorderLayout());
//home screen panel
homeScreen = new JPanel(new BorderLayout());
//homeScreen.setLayout(new BoxLayout(homeScreen, BoxLayout.X_AXIS));
homeScreen.setPreferredSize(new Dimension(320, 320)); // probably you need to remove this line!
JLabel bg = new JLabel();
ImageIcon icon = new ImageIcon("HomeBG.gif");
icon.getImage().flush();
bg.setIcon(icon);
homeScreen.add(bg);
easy = new JButton("Easy");
medium = new JButton("Medium");
hard = new JButton("Hard");
play = new JButton("Play");
//button listeners code here
JPanel buttonsPanel = new JPanel(new FlowLayout(FlowLayout.CENTER));
buttonsPanel.add(easy);
buttonsPanel.add(medium);
buttonsPanel.add(hard);
buttonsPanel.add(play);
homeScreen.add(buttonsPanel, BorderLayout.NORTH);
snake.add(homeScreen, BorderLayout.CENTER);
snake.setTitle("Snake Game");
snake.pack();
snake.setVisible(true);
snake.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
I would use a compound layout for this. Put the level buttons in a (panel in a) FlowLayout. Put the play button in a 2nd FlowLayout. Add those panels to the PAGE_START and PAGE_END of a BorderLayout. Add a label containing the GIF to the CENTER of the same border layout.
BTW - the level buttons should be radio buttons (in a button group - BNI).

First you add the text area panel to the content pane.
Then you add the "FirstScreen" to the frame.
The problem is that when you add the "FirstScreen" to the frame you are really adding it to the content pane of the frame. So basically you are replacing the text area panel with the first screen.
Also, follow Java naming conventions. Variable names should NOT start with an upper case character.

Trying to layout JPanels. Java program layout changes every time I run

First time posting so go easy on me.
I am new to Java and am trying to get 3 JPanels to line up on top of each other. The first image is how I want it to look and it does sometimes when I run the program but as you can see by the other images it doesn't line up every time I run it. Sometimes not even showing some of the images/components.
So how can I get three JPanels to line up one after the other vertically?

Move the frame1.setVisible(true); all the way to the bottom. Changing Components on a frame that is already visible can cause issues.

How to align JPanel in java

I have a JPanel which is in a box layout but I am unsure how to align the JPanel to center of the window (and stay centered even if window is resized) I've tried looking for a solution but all questions seem over complicated compared to what it is that I'm looking for.
import java.awt.*;
import javax.swing.*;
public class Stacker extends JFrame {
public Stacker() {
super("Stacker");
setSize(430, 200);

BoxLayout vertical = new BoxLayout(commandPane,
BoxLayout.Y_AXIS);
commandPane.setLayout(vertical);
JButton subscribe = new JButton("Subscribe");
JButton unsubscribe = new JButton("Unsubscribe");
JButton refresh = new JButton("Refresh");
JButton save = new JButton("Save");
commandPane.add(subscribe);
commandPane.add(unsubscribe);
commandPane.add(refresh);
commandPane.add(save);

You say you're using a BoxLayout, but is the JPanel with the BoxLayout the JPanel you want to center, or does it contain the JPanel you want to center?
If it contains the JPanel you want to center, then you can add a glue on either side of the JPanel to be centered. If it is the JPanel you want to center, then you can use GridBagLayout or BoxLayout to achieve the effect you're talking about.
Googling something like "Java center component" will give you a ton of results.
for this idea (still not clear from your description) use GridBagLayout without set for GridBagConstraints
.

import java.awt.*;
import javax.swing.*;
public class CenteredJPanel {
private JFrame frame = new JFrame("Test");
private JPanel panel = new JPanel();
private JButton subscribe = new JButton("Subscribe");
private JButton unsubscribe = new JButton("Unsubscribe");
private JButton refresh = new JButton("Refresh");
private JButton save = new JButton("Save");
public CenteredJPanel() {
panel.setLayout(new GridBagLayout());
panel.add(subscribe);
panel.add(unsubscribe);
panel.add(refresh);
panel.add(save);
frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
frame.add(panel);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
#Override
public void run() {
CenteredJPanel centeredJLabel = new CenteredJPanel();
}
});
}
}
