Use jFrames as InternalFrames
Hi, I have a problem with a jFrames.
I have a library with some jFrames already defined and programmed, and I have an application project with a MainFrame.
I need to load the library's jFrames inside the Main jFrame on the application project; something like the internalFrames do. I still can't do that.
I want to ask if it is possible to show jFrames contained inside other jFrame, or if I can, somehow, cast or convert a jFrame to a internalFrame to do what I need. Or if I will have to recode the library's jFrames to internalFrames?
thanks for the help you can give me.

Nope. You cannot cast a JFrame as JInternalFrame or vice versa, nor can you make it a child window in the context of an MDI interface. This is one reason why I recommend that most Swing interface elements be placed on a JFrame that way you can plunk them down in a JFrame, a JInternalFrame or a JDialog as the situation demands.
BTW ... This actually belongs in the Swing forum ...
Hope this helps,
PS.

HELP Create Extenstion using JFrame instead of JPanel (10.1.3 Release 3)
Hi,
I manage to create a custom GUI editor in JDev but if i switch it to JFrame, JDev GUI Designer display nothing but an invinsible frame.
I'm using sample from customeditor in extension sdk
Any ideas ?
ThanksIt seems that you are trying to use a JFrame as the GUI of your custom editor. The JFrame is a heavy weight component (has a real window behind it). In JDeveloper custom editors must not use JFrames or AWT Frames as their root GUIs. The windows of these frames will paint on top of other editors even if they are behind in the component stacking order.

Hi All,
I have a window which displays a map. This is done using JFrame. Now, I need to display the status bar at the bottom of the window using JFrame. How do i do it?
Please let me know asap.
Regards
AbhiRead the Swing tutorial on "Using Layout Managers".
http://java.sun.com/docs/books/tutorial/uiswing/TOC.html
You add your "map" panel to the center and your "status" panel to the south.
In the future, Swing related questions should be posted in the Swing forum. -
Inserting a Gui program using JFrames and JPanel
I'm trying to insert a chat program into a game that I've created! The chat program is using JFrames and JPanels. I want to insert this into a GridLayout and Panel. How can I go about doing this?
whatever is in the frame's contentPane now, you add to a separate JPanel.
you also add your chat stuff to the separate panel
the separate panel is added to the frame as the content pane -
How to use JFrame's setLayeredPane() method?

Hi,
I wanted to create a dialog which allows me to have two JTextArea's. In one list I list possible selection for the user. In the other text area, all the files the user selected will be in the text area. There will be two buttons for removal/addition of these items from the second text area. When you hit the OK button the owner of the dialog needs to grab that info.
Can an extension of a JDialog do this? Would it be suited for this? Or should I use an extension of a JFrame?
thanks for any help in advance,
GeoffI would use a JList. The Swing tutorial on "How to Use Lists" gives an example of how to add/remove items from a single list. Changing this to work with two lists should be easy:

How to view images which resides in the database using JFrame.
Hello defts,
Im developing an application using swings. I need to display a image in a JFrame during an button click event. where that image resides in the database.the image shouldn't be in the db, just the path to the image location.
so, open the db, get the location, close the db, get the image from the location,
then either add the image to the frame via a JLabel or a JPanel (and its paintComponent()).
when you add/remove components to the frame you will need to call
frame.validate();, and possibly also
frame.repaint(); -
Beginner question - How to use JFrame class?
How can we use a JFrame class created? Shld you run it like JApplet on browser or appletviewer?
First, if I understand what you want to do exactly, you need to write two classes. The main one will be your class that extends javax.swing.JFrame. Wherehas the second will be your "container class" and will extends java.applet.Applet. This second class will do nothing more than instantiate your JFrame subclass. This is this last class that will be called in your HTML file.
I made up some code quickly to give you an idea:
import javax.swing.JFrame;
public class TestJFrame extends JFrame {
//Constructor
public TestJFrame() {
super("My test JFrame"); //calls the superclass constructor
this.setSize(200,200);
this.setVisible(true);
// Main (optionnal here: just in case you need to
// instantiate the class within an application)
public static void main(String[] args) {
new TestJFrame();
=======================
import java.applet.Applet;
public class TestJFrameApplet extends Applet {
public void init() {
new TestJFrame();
Hope this help -

Design issue using JFrame, JPanel, JLabel
I have been working on this problems for several months now and I and nearly finished.
I have a design question I hope others from this forum can provide some incite to the best approach.
The problem space is a 8 X 8 Chessboard. I have designed a board using JPanels and JLables sitting inside a JFrame. In each square on the chessboard is a JLabel with an image. The "board" sits in the DEFAULT LAYER of a JLayeredPane. As the user clicks a specific square, a queen is placed in the square (8-queens problem). The only thing I do is swap out the image. All this works well--thanks to several of you from this forum. :-)
When I add a new queen to the board, the application goes through the evaluation of attack positions. Next, the application should display the new chessboard with only the queens not threaten by other queens. I keep up with the chessboard using an boolean array internally. I build a second boolean array for the new or refreshed chessboard.
What I want to do is build a second chessboard and "swap" it out with the one in the default layered pane. Can someone be so kind and shine some light on this design issue for me?
Thank you for taking the time to read my post.I don't understand this approach. Swing is by default 'double buffered' and will not flicker. You will get this be default since this is one of the things the Swing painting model gives over AWT.
You should look at just using JComponent and the paintComponent() method for drawing what you need.
What I've done in the past is have a simple XML JDoM model. Have components that render themselves based on this model.
Changing the model then I just issues a call to repaint() at the top level container.
You can also add and remove items from the parent container. Then issue validate() or repaint(). Can't remember now but I think validate() hits the layout manager logic and then repaints.
I'm pretty sure the Romain guy posted an example of how to easily draw a background chess board in a panel. ;-)
The tree concept might really prove useful for a 'gaming tree' approach at the AI also.
If you look at the Java3D API you will see they use a tree to represent what is rendered and the details about it. Really nice until you change something in the tree that cause the renderer to blow up. ;-)
I guess the moral is always make small simple changes and test.
Hope this is helpful. -
Hello,
Is it possible to run JFrame application using JDK from dos command line.
If yes how can I do it ?note: you will need to have ur files in the same
directory as your java.exe and javac.exe for this to
work :DTo be able to use java.exe and javac.exe, simply add the path to these files in yoiu PATH definition. Under Win9x, see the autoexec.bat file. In Win2K, go to system Properties, System, Environment variables and edit the PATH...
after this, make a try with "java.exe -version". You should receive some comments about your JRE version

Greetings:
I've found searching at the net, that it is suggested "that the L&F (rather than the system) decorate all windows. This must be invoked before creating the JFrame. Native look and feels will ignore this hint". The command that does this is the static JFrame.setDefaultLookAndFeelDecorated(true); .
If I install Metal L&F as default, and then go to Full Screen and change the L&F, it partially WORKS (the Metal L&Fdecorations are set like in an InternalFrame); but if I set the System L&F as default and change the L&F, the new L&F does not recive its propper decorations but rather the system ones.
Could anyone help me in this issue?
Thanks a lot in advanced.

}Greetings:
Thanks a lot for your kind answer:
After reading your reply, I've done some studies directly in the API in how does the L&F's are managed. Of what I've understood (please correct me if I'm wrong), the things are as follow:
i) System and Motif Look and Feel's does NOT support decorations, so that's why you should let the JVM do the decoration work (that is, use myFrame.setUndecorated(false); ).
In this case, it does not matter if you use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of the frame: it won't show decorations if you don't use the command mentioned.
ii) Metal (Java) Look and Feel DOES support decorations; that's why, if you use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of the frame, you'll see it's own decorations. In this case, you should use myFrame.setUndecorated(true); so the L&F does all the decorating work, avoiding the weird sitiuation of showing double decorating settings (L&F's and native system's).
iii) So, the real problem here would be if you want to have, as a user choice, that the System/Motif L&F's will be available together with the Java's (Metal). I've made the next variation to my code, so that this will be possible:
class LookAndFeel_ActionListener implements ActionListener {
private ButtonGroup eventButtonGroup;
private MainWin eventFrame;
public LookAndFeel_ActionListener (ButtonGroup buttonGroup, MainWin eventFrame) {
this.eventButtonGroup = buttonGroup;
this.eventFrame = eventFrame;
public void actionPerformed(ActionEvent event) {
String command = eventButtonGroup.getSelection().getActionCommand();
GraphicsDevice scrnDevice = GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice();
eventFrame.dispose();
if (command.equals("System")) {
try { UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
eventFrame.setUndecorated(false); // make sure the native system controls decorations as this L&F doesnt's manage one's.
catch (Exception e) { }
else { if (command.equals("Java")) {
try { UIManager.setLookAndFeel(UIManager.getCrossPlatformLookAndFeelClassName()); }
catch (Exception e) { }
eventFrame.setUndecorated(true); // make sure the L&F controls decorations as it actually has one's.
else { if (command.equals("Motif")) {
try { UIManager.setLookAndFeel(new MotifLookAndFeel()); }
catch (Exception e) { }
eventFrame.setUndecorated(false); // make sure the native system controls decorations as this L&F doesnt's manage one's.
else { }
SwingUtilities.updateComponentTreeUI(eventFrame);
if (eventFrame.FullScrnOn){ try {scrnDevice.setFullScreenWindow(eventFrame); }
finally { }
} else { }
eventFrame.setVisible(true);
}iv) The issue here is that, as I needed to use myFrame.dispose() (the JVM says that it is not possible to use setUndecorated(false); in a displayable frame), I recieve and error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalStateException: Buffers have not been created
at sun.awt.windows.WComponentPeer.getBackBuffer(WComponentPeer.java:846)

at javax.swing.JComponent.paint(JComponent.java:1015)
and, yet, the Metal (Java's) L&F keeps without decorations. Is it there a way to solve this without having to create a new instance of the frame and use JFrame.setDefaultLookAndFeelDecorated(true); before the creation of such new instance of the frame for the Metal's (Java) L&F?
Thanks again for al lthe help: this was, definetelly, something not obvious to figure out (or to find a hint on the net).

How can I use internal frames with buttons to call others internal frames?
Hello.
I'm building a MDI-application using JFrames and several JInternalFrames, but I have problems.
A JFrame has JMenuBar with JMenu and JMenuItem. One of these, call the first JInternal that has its interface. In this interface has a button that call other type (a class extension of JInternalFrame) JInternalFrame.
When I clicked button happen a exception (java.lang.NullPointer).
What happening?
Help me, please.What i usually do is to give my desktop to my internal frames. So within the internalframe, you can use your desktop and add other internal frames to it.
The code should look something like the following.
desktop = your JDesktopPane
MyInternalFrame = an InternalFrame
AnotherMyInternalFrame = another InternalFrame
public class MyInternalFrame extends JInternalFrame implements ActionListener
private JButton jb = new JButton("Launch");
private JLayeredPane desktop = null;
public MyInternalFrame(JLayeredPane desktop)
this.desktop = desktop;
getContentPane().add(jb);
jb.addActionListener(this);
public void actionPerformed(ActionEvent ae)
if (ae.getSource() == jb)
desktop.add(new AnotherMyInternalFrame(desktop),JLayeredPane.DEFAULT_LAYER);
