I want when i select first JRadioButton, other JRadioButton should be unselected.
I use ready jframe, how can change netbeans generated code?
How do this?
By default, a new JRadioButton is created in its own ButtonGroup, which means they can both be selected independently.
If you want the two buttons linked so that only one can be picked at a time, you need to add:
ButtonGroup group = new ButtonGroup();
group.add(jRadioButton1);
group.add(jRadioButton2);
After you have constructed the buttons.
Add the 2 JRadioButtons to a single javax.swing.ButtonGroup instance.
See: How to Use the ButtonGroup Component
Use ButtonGroup :
ButtonGroup buttongroup = new ButtonGroup();
buttongroup.add(...);

So let's start with some background this is for a first year collage project. the GUI is built so one class, the interface-handler calls all the JPanels and puts them in the right place. This is for structure and so it's easy to maintain.
the problem is the panel holding the menu does't show it's components after it's added. i'll include some image's so it's easier to understand.
The panel in question is called MenuPanel.
so here is the login button which currently only clears the contentpanel and then adds the menupanel.
Login page where the button is located
and here is the menu panel empty
here is the menu panel all empty
the code
The interface handler
you can see me messing around with the .repaint() method in the menu method already.
public class InterfaceHandler {
private static InterfaceHandler singleton;
/**
* Checks if there is already a instance running of InterfaceHandler if so
* return the instance if not create a instance.
*
* #return Instance
*/
public static InterfaceHandler instance() {
if (singleton == null) {
singleton = new InterfaceHandler();
}
return singleton;
}
private ContentPanel contentPanel;
private LoginPanel loginPanel;
private MainFrame mainFrame;
private MainPanel mainPanel;
private MenuPanel menuPanel;
/**
* Initializes default Interface
*/
public InterfaceHandler() {
initComponents();
}
/**
* Initializes GUI Components that will be needed now or in the future.
*/
public void initComponents() {
mainFrame = new MainFrame();
mainPanel = new MainPanel();
contentPanel = new ContentPanel();
loginPanel = new LoginPanel();
menuPanel = new MenuPanel();
contentPanel.setBounds(100, 100, 860, 700);
menuPanel.setBounds(10, 10, 80, 400);
loginPanel.setBounds(280, 250, 300, 200);
mainFrame.add(mainPanel);
mainPanel.add(contentPanel);
mainFrame.setVisible(true);
contentPanel.add(loginPanel);
}
/**
* Clears the ContentPanel of all components
*/
public void clear() {
System.out.println("Clear Ran");
contentPanel.removeAll();
contentPanel.repaint();
}
/**
* Adds the Login Screen.
*/
public void login() {
System.out.println("Login Ran");
contentPanel.add(loginPanel);
contentPanel.repaint();
}
/**
* Adds the menu.
*/
public void menu() {
System.out.println("Menu Ran");
mainPanel.sidePanel.add(menuPanel);
menuPanel.repaint();
mainPanel.repaint();
mainPanel.sidePanel.repaint();
}
}
And here is the code for the panel, Most of it is autogenerated by the netbeans design editor.
so it's ugly (i'm sorry)
public class MenuPanel extends javax.swing.JPanel {
/**
* Creates new form MenuPanel
*/
public MenuPanel() {
initComponents();
}

just to clarify, the method menu is called from a different class.
If you are adding components to an already visible panel, you need to call validate().
public void menu() {
System.out.println("Menu Ran");
mainPanel.sidePanel.add(menuPanel);
mainPanel.sidePanel.validate(); // try this
menuPanel.repaint();
mainPanel.repaint();
mainPanel.sidePanel.repaint();
}
(This answer is wrong but the ensuing comments do help understand why #whiskeyspider's answer is right)
In this code:
mainFrame.add(mainPanel);
mainPanel.add(contentPanel);
mainFrame.setVisible(true);
contentPanel.add(loginPanel);
You're not adding menuPanel anywhere. It is added (too late) in the menu() method, but that's not being called.
I'm creating a "Presentation" on a jFrame as part of a project and need some help.
I have it starting as a 200, 200 size frame with a button in the middle that says "Let's Start"
then when you click on it, the size of the frame changes. When I click on the button you have to drag the window to make it the already defined size seen as the window stays the original 200 by 200 it doesn't open the window to 1335 by 675.
Here's my code.
package randomGUIs;

I've tried using startPanel.repaint(); with no luck.
Simply set the frame size with this function.
In order to use this function you must include the relevant package.
import java.awt.Dimension;
...
setSize(new Dimension(1320,220));
Your JFrame won't automagically resize itself unless you tell it to. Something like this:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
startPanel.setSize(new Dimension(1335, 675));
startPanel.setMaximumSize(new Dimension(1335, 675));
startPanel.setMinimumSize(new Dimension(1335, 675));
frame.setSize(1335, 675);
jButton1.setVisible(false);
}
You could also use the pack() function of the JFrame class, depending on what you wanted to do.
This is a simple code to clarify my question:
this is the main class from where I declared the two panels.

My question is.if I put a value in the textarea of the first card and press the login button.the value will appear in the text area of the second card.how can i do it?
You somehow have to pass a reference of the second panel to the first one:
Main class:
public class MainPane
{
public void displayGUI()
{
....
p1 = new Firstcard1(contentPane);
p2 = new SecondCard1(contentPane);
p1.setSecondCard(p2);
....
}
}
First card:
public class Firstcard1 extends javax.swing.JPanel {
....
private SecondCard secondCard;
void setSecondCard(SecondCard secondCard)
{
this.secondCard = secondCard;
}
....
private void LoginActionPerformed(java.awt.event.ActionEvent evt)
{
CardLayout layout = (CardLayout)contentpane.getLayout();
layout.show(contentpane, "Panel 2");
secondCard.getTextField().setText(jTextField1.getText());
}
}
Second card:
public class SecondCard1 extends javax.swing.JPanel
{
...
JTextField getTextField()
{
return jTextField1;
}
...
}
But when you continue like this, the program will probably become a mess pretty soon. I'd recommend to create these components manually, without using any visual GUI builders.
I have a GUI as shown below. the tabbed pane in the card layout card 1 panel show 1st tab by default. When i navigate to card 2, I would like to know how to make the button there to navigate to card 1 tab 3. I know how to get to card 1 from that button by using getParent(), but I don't know how to show a specific tab I want from there. (Note: card 1 and card 2 are two different JPanel classes, the parent is a JFrame class)
Image: Left side as card 1 with tabbed panel , Right side as card 2

I think you're looking for JTabbedPane.html.setSelectedIndex(int).
The following isn't the most elegant solution, but it should work without requiring a lot of refactoring.
Add a method in NewJFrame:
public CardLayoutTest.JPanelCard1 getJPanelCard11() {
return jPanelCard11;
}
Add a method in JPanelCard1:
public void setTab(int index) {
jTabbedPane1.setSelectedIndex(index);
}
Call these in JPanelCard2:
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
//show card 1 from here
CardLayout card = (CardLayout) this.getParent().getLayout();
card.show((JPanel) this.getParent(), "card1");
//card1 shown, show specific tab in the tab pane from here:
NewJFrame parent = (NewJFrame) this.getParent();
((JPanelCard1) parent.getJPanelCard11()).setTab(1);
}
I've created and application in which there are two tabs titled Tabbedpane 1 and Tabbedpane 2. In one tab body Tabbedpane 1 contains a JInternalFrame in which there is a search button. On clicking the button another JInternalFrame opens within the main JInternalFrame.
Can anyone please tell me how to close the said opened JInternalFrame ie the search JInternalFrame while clicking on to the second tab titled Tabbedpane 2
I've tried .setClosed(true) and .setVisible(true) on property change still it does'nt works for me.
Use a ChangeListener which will get notified when JTabbedPane state changes (i.e tabs switched):
final JTabbedPane tabbedPane = new JTabbedPane();
tabbedPane.addChangeListener(new ChangeListener() {
public void stateChanged(ChangeEvent e) {
//tab has been changed
}
});
The problem is we will need a way to monitor the previous tab i.e the tab we were on before it was changed this can be done via:
tabbedPane.addChangeListener(new ChangeListener() {
int prev_index = 0;
int curr_index = 0;
public void stateChanged(ChangeEvent e) {
prev_index = curr_index;
curr_index = tabbedPane.getSelectedIndex();
System.out.println("Tab (Current): " + curr_index);
System.out.println("Tab (Previous): " + prev_index);
}
});
UPDATE 1:
To close JInternalFrame I'd suggest calling dispose() on its instance
UPDATE 2:
Here is your fixed code, basically added a getter for Search class, thus JIFrame1 has a getSearch() method which allows us to gaim access to the Search classes current instance created in JIFrame1, in changedState(..) I call jiFrame1.getSearch().dispose() which will make sure we dispose of the instance that has already been created:

((javax.swing.plaf.basic.BasicInternalFrameUI) jiframe1.getUI()).getNorthPane().removeMouseListener(listener);
}
jiframe1.setLocation(10, 10);
jiframe1cont.add(jiframe1);
jiframe1.setVisible(true);
JIFrame2 jiframe2 = new JIFrame2();

if(s!=null)
s.dispose();
