I would like to know the possible ways to put up JInternalFrame over JPanel to achieve the following output.
Is it even Possible because i learned JInternalFrame can only be added to JDesktopPane.?
I have an MVC application with JInternalFrame, I want to insert the ScrollBar when the contents of JInternalFrame is great. How can I do?
The code that I wrote this but I do not know how to insert the scrollbar
frame = new JInternalFrame(nameFile);
frame.addInternalFrameListener(this);
panelFrame = new JPanel();
JLabel labelF = new JLabel();
[Code]....
I got a JFrame with its JDesktopPane, and opens a JInternalFrame at the beginning of the execution of the application. That's all fine.
And then, the first JInternalFrame opens another JInternalFrame in its maximum size, and that's when a simple JLabel that I got o the second internal it disapears. Why?
I am in the progress of updating my code and re-testing after switching from Java 6 to Java 7. When I open multiple JInternalFrames in my application under java 6 I am used to closing the top most internal frame and having the frame immediately under it become the next active frame. When I run the same code under Java 7 I see a different behaviour in as much as when I close the last frame I opened, the next one to become active is the first one.
To illustrate this another way, lets say I open 5 internal frames, 1,2,3,4 & 5
In java 6 when I close frame 5, frame 4 becomes the active frame.
In java 7 when I close frame 5, frame 1 becomes the active frame.
I'm having issues with providing focus to keyboard buttons when a JInternalFrame with keyboard buttons is called in my program. So for example when the program is started the attachment called signinscn.png is called.
This screen is a JDesktopPane which calls JPanel for its components.
From here a JInternalFrame containing the buttons ESC and F1 to F4 as seen in the attachment called signinscn.png is called.
I would like the buttons in my JInternalFrame to have focus such that when a user engages the equivalent keyboard button i.e. ESC or F1 to F4 WITHOUT clicking on the JInternalFrame the respective button's action listener kicks in. At the moment only after the user clicks on the JInternalFrame do the equivalent keyboard buttons respond.
Here's the constructor of my JInternalFrame and you can see how I handle the ESC keyboard button in the constructor of the JInternalFrame (but as I mentioned only after the user has engaged the JInternalFrame):
//!<
public AdminHomeJIFrame() {
super(null, false, // Resizable
false, // Closable
false, // Maximizable
false); // Iconifiable
BasicInternalFrameTitlePane titlePane =
(BasicInternalFrameTitlePane)((BasicInternalFrameUI)this.getUI()).getNorthPane();

Trying to get an image to display in a GUI.
try {
ByteArrayInputStream in = new ByteArrayInputStream(
transferWorker.bOutput
.toByteArray());
BufferedImage bufferedImage = ImageIO
.read(in);
[Code] ....
But nothing is happening in the GUI. I have stepped through and bufferedimage contains the data, but its not being displayed. Whats happening is, an image is being transmitted to serial port of laptop, so i'm taking it in and storing it in a BufferOutputStream and then trying to open it in my GUI class.
I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
How can I make a call to paintComponent within the JPanel-class, from another Class?
In class TestClass:
public class TestClass {
public TestClass() {
JFrame frame = new JFrame();
frame.setLayout(new BorderLayout());
frame.setSize(500,500);
initComponents();

I have been trying to create a chat client which makes use of a scrollable jpanel and at runtime adds JTextFields to the panel.
Panel Initialising
msgPanel = new JPanel(new MigLayout());
msgPanel.setPreferredSize(new Dimension(400,335));
JScrollPane msgPanelScroll = new JScrollPane(msgPanel);
msgPanelScroll.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);
msgPanelScroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
mainPanel.add(msgPanelScroll,"span 3,alignx center,wrap");
[Code] .....
But now Im facing the following issues. The text field aligns to the center of the panel & on adding more fields the panel accommodates as it can and does not begin scrolling.

I pick this code from Head first Java

but just a Jframe is appearing no Jpanel no green color circle?What is wrong with code
I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons. (notice only run method in the second class):
JPanel Menu that will be used in all alone JFrames of application:
public class MenuSuperior extends javax.swing.JPanel {
public MenuSuperior() {
initComponents();
} private void initComponents() {

Let me explain by simplifying the GUI to a simple frame in which I have a JCheckbox and a JPanel mypanel.mypanel has a Textfield tf,JComboBox cmb as it's components.So now if I deselect the JCheckbox, all the components in the mypanel should be disabled. I used a code like:
[code]mycheckbox.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
if(mycheckbox.isSelected())
mypanel.setEnabled(true); else
mypanel.setEnabled(false); } });[code]
but the components inside the panels are not disabled. In my actual program I have a large number of different kinds of components in mypanel.So disabling/enabling each of them on each actionPerformed of the mycheckbox will be laborious. Isn't there any way by which I can disable/enable the mypanel to disable/enable all the components in it?
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
MainViewClass:
...
private void initComponents() {
...
MenujPanel = new MenuSuperior();
MenujPanel.setBorder(
BorderFactory.createTitledBorder("Dados Pessoais"));

I need to add 2 JLists inside a JPanel for a crossword. The JPanel is located SOUTH and I'm using BorderLayout in the constructor to locate the JPanel.
The problem is, I can't see the 2 JLists inside the JPanel. For some strange reason the JLists appear in the center where the crosswordPanel is, even though the clues JPanel method is located SOUTH.
package crossword;
import java.awt.BorderLayout;
import java.awt.Color;

I am trying to add buttons in a loop to my but when i compile my program i can`t see my buttons. I can see other stuff that added to jpanel ...
static JButton blocks[][];
for (int i = 0; i < block.length; i++) {
for (int j = 0; j < block[i].length; j++) {
block[i][j] = new Block(i, j);
blocks[i][j] = new JButton(i+"");
blocks[i][j].setLayout(new GridLayout((i+1) * 10, (i+1) * 10, 10, 10));
pageAxisPanel.add(blocks[i][j]);
}
}
I have used the following code and I am trying to render a String in the JPanel. The text is getting displayed in the mirror image format.
I understand that there is a problem with .scale(), not able to get an idea about the corrective step. Please run the below class.
class Surface extends JPanel {
final int PAD = 40;
private void doDrawing(Graphics g)
{
Graphics2D g2d = (Graphics2D) g.create();
g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
RenderingHints.VALUE_ANTIALIAS_ON);

I'd like to enable/disable a jpanel and it's entire contents in one fell swoop. I could of course call each component's .setEnabled() method, but I figured there must be a better way!
View Replies View RelatedI have created a JFrame that contains 3 JPanel.
My problem is, when i clicked in the bouton to expand the Frame,the 3 JPanel are fixed and do not expanded with the Jframe.
My JPanel when adding components to it will never make its self larger but it will make my components inside smaller even though I have set the minimum and preferred sizes for those components? I am using the GridBagLayout for my layout manager as I am trying to get used to it.

I'm writing a Java Swing program for my software development class to allow a user to create a map for a side scroller video game. I'm stuck on a particular part of my GUI where I'm trying to create a properties box for specific tiles. When I draw the components onto the JPanel and display it as it is, it shows two check boxes per row. On the ScrollPane however, all the check boxes go straight onto one line and draw out the scroll pane. Right now I am only concerned with just making the basic GUI.
Here is what I have so far:
Within the main class, I am creating the JFrame and adding components to it. I am attempting to create a JScrollPane which will hold the properties check boxes...
Here is the method where I am implementing the code. It works, but it doesn't display correctly.
private void createPropertiesBox() {
PropertiesBoxPanel pbp = new PropertiesBoxPanel();
propertiesBox = new JScrollPane(pbp);
propertiesBox.setViewportView(pbp);
frame.add(propertiesBox);

Is it possible to create a JInternalFrame class with additional public functions that can be called from the desktop? Here is some snippets of the code. This is the Internal Frame with the public functions added after the constructor.
public class Search_Ifr extends javax.swing.JInternalFrame {
/**
* Creates new form Search_Ifr
*/
public Search_Ifr() {
initComponents();
[code].....
The line " ifrSearch.setTabPaneIndex("tabCust");" is throwing a compile error that the method is not found.
Java Code:
import javax.swing.*;
public class AnimateJInternalFrame {
JFrame jf=new JFrame();
JInternalFrame jif=new JInternalFrame();
Timer t;

I want that JInternalFrame to animate smoothly downwards but it isn't working.
