Problem using extended JPanel
Hi, I'm using JDeveloper 10.1.3.3. I've extended JPanel and named it TestPanel, and then have added few textboxes, one checkbox and one combobox. It was created as runnable panel. When I run that panel, everything worked fine. I used it in custom JFrame instead of dataPanel:
TestPanel dataPanel = new TestPanel();
Whatever I did, I couldn't see components on that custom panel. I tried to rebuild, run frame, I couldn't see it.
Then I've tried to create another panel in original dataPanel (JPanel, BorderLayout), and use TestPanel that way. Didn't work. Does anyone know what might be the problem?
Colleague helped me.
Created custom panel is placed in Components View as ADF Swing Regions -> view.TestPanel, so it can be dragged and dropped.
If creating panel in code, after creating custom JPanel
TestPanel dataPanel = new TestPanel();
There must be this line in jbInit() method:
testPanel1.bindNestedContainer(panelBinding.findNestedPanelBinding("TestPanelPageDef1"));

Extending JPanel to contain a JRootPane - problems with scroll panes
I am trying to write a JPanel subclass that contains a JRootPane, similar to the way that JFrame contains a JRootPane. The reason that I am doing this is that I would like to be able to intercept mouse events using the JGlassPane facility, but adding the glasspane to the JFrame is problematic since it then intercepts mouse events over all components in the JFrame, including the menu bar. It seems simpler to me to have the JRootPane owned by a JPanel, to give me better control over intercepting events. I've got an implementation working with the JFrame case, but have had to handle many small "gotchas", and at least one more exists. I'm hoping to simplify things by moving away from this way of doing things.
I wrote a straightforward RootPanePanel class that extends JPanel and implements RootPaneContainer, delegating all of the add methods to the JRootPane's content pane. Here's the constructor for RootPanePanel:
public RootPanePanel (LayoutManager layout) {
rootPane = new JRootPane ();
rootPane.setOpaque(true);
rootPane.getContentPane().setLayout(layout);
super.add (rootPane);
}RootPanePanel also delegates calls like getContentPane/setContentPane to the JRootPane.
To test my implementation, I wrote a main method that looks like the following:
public static void main (String[] args) {
SwingUtilities.invokeLater(new Runnable () {
public void run () {
try {
JEditorPane editorPane = new JEditorPane ("http://www.archives.gov/exhibits/charters/print_friendly.html?page=declaration_transcript_content.html&title=NARA%20%7C%20The%20Declaration%20of%20Independence%3A%20A%20Transcription");
JScrollPane scrollPane = new JScrollPane (editorPane);
JFrame frame = new JFrame ("Test RootPanePanel");
RootPanePanel panel = new RootPanePanel ();
panel.add(scrollPane);
frame.add(panel, BorderLayout.CENTER);
scrollPane.setPreferredSize(new Dimension(800, 600));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize (640, 480);
frame.pack ();
frame.setVisible(true);
} catch (Exception e) {
e.printStackTrace();
});Note that I'm not actually using JEditorPane in my application, but it is the simplest component that displays the problem I'm encountering.
When this code runs, it is fine, as long as the JFrame is big enough to display the scrollbars for the JScrollPane. If the JFrame is made small enough, the scrollbars are not displayed.
If I instead add the JScrollPane to the JFrame directly, it behaves as you would expect.
Is this a problem of mixing heavyweight and lightweight components? It doesn't seem like it should be; in both cases the JScrollPane is handling the same client component, the JEditorPane.
Any suggestions/ideas are welcome!Here's the full RootPanePanel class in case people want to try it out

Hi,
What is the best format to have a class with a JFrame and a number of JPanels, one of which needs to be painted on using Graphics.
class Demo extends JPanel{
public JFrame frame;
public JPanel panel1;
public JPanel panel2;
public JPanel panel3;
Demo(){
// initialise JFrame
frame = new JFrame();
// initialise a few JPanels
panel1 = new JPanel();
panel2 = new JPanel();
panel3 = new JPanel();
// refer to the JPanel I'm painting on
frame.getContentPane(this); // Is this correct?
public void paint(Graphics g) {
g.drawString("Click below", 50, 50);
// now this method should paint over one of the JPanels only, the one I'm extending..
}Any thought appreciated.Thanks for the pointers Haynese ,
I understand what I should be doing.
I have another issue with this now, maybe its constructed badly...
I can get the graphics objects on the JPanel to display but not the JButton or label I add. If I click in the region of the button and hit it, it appears. Any ideas?
public class GraphEditor extends JPanel implements MouseListener
public JButton button;
public JLabel label5;
public GraphEditor(){
// JPanel Button, displays if clicked on.
button = new JButton("JPanel Button, displays if clicked on...");
this.add(button);
// This should display but never does
label5 = new JLabel("This should display but never does");
add(label5);
setSize(50,50);
setVisible(true);
public void paint(Graphics g) {
// This displays fine
g.drawString("This displays fine", 5, 5);
}and:
public class SystemWindow extends JFrame {
public JButton button;
public JPanel topPanel;
public JPanel bottomPanel;
public JPanel mainPanel;
public JLabel topPanelLabel;
public JLabel bottomPanelLabel;
public JButton getPathButton;
private GraphEditor mainMap = new GraphEditor(this);
SystemWindow(){
topPanel = new JPanel();
bottomPanel = new JPanel();
mainPanel = new JPanel();
// 10 is horizontal
// 01 is vertical
getContentPane().setLayout(new GridLayout(0,1));
getContentPane().add(mainPanel);
mainPanel.add(topPanel);
mainPanel.add(bottomPanel);
topPanelLabel = new JLabel("Top Panel");
topPanel.add(topPanelLabel);
bottomPanelLabel = new JLabel("Bottom Panel");
bottomPanel.add(bottomPanelLabel);
button = new JButton("Save");
//button.addActionListener(this);
bottomPanel.add(button);
getPathButton = new JButton("Get");
//getPathButton.addActionListener(this);
bottomPanel.add(getPathButton);
getContentPane().add(mainMap);
setTitle("App Title");
setSize(500,300);
setLocation(100,100);
mainPanel.setVisible(true);
topPanel.setVisible(true);
bottomPanel.setVisible(true);
setVisible(true);
} Any suggestions welcome. -
Problem with extending an extended class
Hi JDC
I have to use a scrolled list several times among my program so I create a class named ScrolledList that extends Jpanel and an inner class that extends ScrolledLIst.
The problem shows up when I?m trying to add an item inside the inner class, the code pass compilation, it even enter the addItem() but its dont add item
public class ScrolledList extends JPanel{
DefaultListModel dlm = new DefaultListModel();
JList list = new JList();
JScrollPane js = new JScrollPane(list);
ScrolledList(){
setLayout(new BorderLayout());
add(js,BorderLayout.CENTER);
}here is the class i use whenever i need this scrolled list:
public class innerClass extends ScrolledList{
public void addItem(String item){
System.out.println("addItem invoked...");
this.dlm.addElement(item);
public static void main(String[] args) {
JFrame frame = new JFrame("InnerClass");
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
frame.getContentPane().add(new innerClass(),
BorderLayout.CENTER);
frame.setSize(400, 125);
frame.setVisible(true);
innerClass ic = new innerClass();
ic.addItem("Shay");
}what im doing wrong(code example please)?
ThanksHi
i tried this , its still dont add item to the list:
import javax.swing.*;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class ScrolledList extends JPanel{
//List variables
private DefaultListModel dlm = new DefaultListModel();
private JList clientsList = new JList(dlm);;
private JScrollPane clientScroll = new JScrollPane(clientsList);
public final boolean PRINTLN=true;
public void p(String out){
if(PRINTLN)
System.out.println(out);
public ScrolledList() {
try {
jbInit();
catch(Exception e) {
e.printStackTrace();
private void jbInit() throws Exception {
this.setLayout(new BorderLayout());
this.add(clientScroll);
public void addClient(String client){
p("addClient invoked....");
dlm.addElement(client);
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.getContentPane().add(new ScrolledList());
frame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
frame.setSize(300,300);
frame.setVisible(true);
ScrolledList s = new ScrolledList();
s.addClient("Shay");

Extended JPanel not rendering correctly
I am using a split pane. One pane is a JScrollPane with a JTree attached, the second is a JScrollPane with a JPanel attached. The idea is to show different panels in the second pane depending on which node of the tree is selected.
My problem is that I when I select a node on my tree in the first panel, my second panel shows only a small grey square.
My extended JPanel class is:
public class onePanel extends JPanel {
public void onePanel() {
JLabel jLabel1 = new JLabel();
jLabel1.setText("Node One");
add(jLabel1);
In my main I am calling:
JPanel info = new JPanel();
JScrollPane myScrollPane = new JScrollPane(info);
onePanel op = new onePanel();
info.removeAll();
info.add(op);
info.revalidate();
Any help on this matter would be much appreciated. Let me know if you need more information. Thanks.
FoxMy boss helped me with this one as well as bharatchhajer . I'll post the answer for future reference:
I made the change suggested by bharatchhajer to leave out the intermediate info panel and just deal directly with the JScrollPane.
In the subclass, instead of using the default constructor OnePanel(), I passed the parent. In this case, OnePanel(myScrollPane).
I added this to the subclass:
myScrollPane.add(this);
Also, instead of myScrollPane.add(info); I used:
OnePanel op = new OnePanel();
op.OnePanel(myScrollPane);
myScrollPane.setViewportView(op);
So the main problem was that my subclass had no idea about what to attach to. The handle or parent had to be passed to it.

HELP, HELP, HELP, Problems using GridBagLayout with a BorderLayout
I have a BorderLayout for my application. I created a JPanel that has the following items added to it:
1)Button
2)VisualComponent
3)ControllerComponent
The JPanel is then added to the WEST Pane of the BorderLayout. My problem is that I can not get my components in the JPanel to display correctly. The items should be added from top to buttom in my JPanel, but they overlap and display side by side, and some don't appear at all until my entire window application is Maximized. It seems as if all my components are trying to display in one row even though I explicitly add them to different rows as follows:
1)addUsingGBL(openFile,0,1,2,1);
2)addUsingGBL(visualComponent,1,1,1,3);
3)addUsingGBL(controlsComponent,4,1,2,1);
where addUsingGBL is as follows:
void addUsingGBL(Component component,int row, int column, int width, int height)
gbc. gridx = row;
gbc.gridy = column;
gbc.gridwidth = width;
gbc.gridheight = height;
gbLayout.setConstraints(component, gbc);
mediaPanel.add(component);
mediaPanel.doLayout();
If anyone has any suggestions, I would greatly appreciate it. Entire code is available if needed. Thanks!Here is the code, sorry, didn't see that part before.

JButton not visible after use of Jpanel removeAll ..
Hi!
I'm having a calculator class that inherits JFrame. I need to add more buttons after setting an option from the (view) menu bar .. (from normal to scientific calculator). I needed to use the JPanel removeAll method and then add the normal buttons plus extra buttons. But the problem is, that the Buttons are only visible when I touch them with the mouse.
Does anybody know why? Thanks for your help!

dungorgSwing related questions should be posted in the Swing forum.
After adding or removing components from a visible panel you need to use panel.revalidate() and sometimes panel.repaint();
If you need further help then you need to create a [url http://homepage1.nifty.com/algafield/sscce.html]Short, Self Contained, Compilable and Executable, Example Program (SSCCE) that demonstrates the incorrect behaviour, because I can't guess exactly what you are doing based on the information provided.

Any replies will by imprecated
Shay GagheYou could try using JLabel instead of subclassing JPanel. Just set the label's icon and don't set any text.
I also agree that GridBagLayout is the most useful layout. When I was new to Java programming it was the most confusing. In order to do complicated graphical interfaces I use to have to use a lot of nested panels with different layouts. Even then I had problems because I couldn't specify exactly which component should expand etc. Now, two years later and after becoming a Sun certified programmer for the Java 2 platform, I use GridBagLayouts almost always and it give me the most flexibility. It allows me to make some really professional gui programs. I recommend spending some time getting used to using GridBagLayout more. -
Problem using the setPage(String url) of JEditorPane
Hi all !
I'm developping a text file generator which generates a text file and use a viewer to display the content of this text file.
The first time, it works correctly, it displays the text file content but the others times it doesn't work correctly, the first text file content remains displayed.
It seems that the setpage(String url) method doesn't work correctly.
Does anyone know this problem ?
In advance, thanks a lot.
Best regards,
Farid.
Here is the code of the viewer:

}hi,
there is some problem with JedtorPane when you update the page. Image or not updated all the time because the buffer keep the old image and does not update it. The problem is that class got to much protected field so you cannot change nothing. It is a bug since Two years and no body as correct it. -
GUI Problem (Swing JFrame/JPanel). HELP!
Hi,
I made an small application for calculate some things.
I download i piece of code for creating bar chart and i icluded in my code. But i have problem when i am trying to show the chart in the Frame. All the buttons, textfields, labels goes to left and half are hiding.
If i open the chart on a new frame i dont have problem.
the problem apears when after i put the panel in the frame i try to put the chart in the frame. Look the code:
add(p); //Put the panel in the Frame
this.getContentPane().add(new ChartPanel(values, names, "Fertilizer Plant")); // <-- The problem!!that command mades me the problem!
Here are 2 screenshots
1. When i put the chart in the Frame (the problem)
http://www.iweb.gr/images/InFrame.jpg
2. When i put the chart on new frame (works fine)

What's the first rule of Swing? DO NOT MIX heavyweight AWT components and lightweight Swing components. Period. Never.
There's Swing equivalents for every single AWT component, and then some. There's no excuse for not using them.
However, if this chart library code is AWT based, then you should make a completely AWT based UI. Or find a different library based on Swing (like JFreeChart).
And finally:
add(p); //Put the panel in the Frame
this.getContentPane().add(new ChartPanel(values, names, "Fertilizer Plant")); // <-- The problem!!is wrong....
add(p); // <-- The problem!!
this.getContentPane().add(new ChartPanel(values, names, "Fertilizer Plant"));You don't call add on JFrame or JDialog to add things to it, unless you know what you're doing. And you clearly don't, else you wouldn't have done it. What you probably want to do is this:
this.getContentPane().add(p, BorderLayout.SOUTH);
this.getContentPane().add(new ChartPanel(values, names, "Fertilizer Plant"), BorderLayout.CENTER); -

You should also use code tags as I have demonstrated above. It makes you code easier to read for the people you are asking to help you. You can read about them under Formatting Help on the page you post on. -

That image basically describes my problem, it keeps drawing what I want to draw over it-self, using clearrect() it just gives me grey in the back ground when I draw a rect with 0 alpha over it, it presents me with black in stead of something that has 0 alpha. The pane with the selection thing drawn on it is a glasspane of the JDialog you see.

After that, I tried setting permissions for the cwallet.sso file to ugo+rwx, but this leads to the same problems as mentioned above.
My second try was to setup an external WLS 12c, but it seems to be not yet possible to connect to a WLS 12c from within jDeveloper.
Do you have any ideas ?
Thank you in advance for your help.
Regards,
RobinAfter debugging the WLS Initialisation with jdb, I recognized that there was some trouble with dependent libraries.
In the end, I solved my problem by using another OS (Ubuntu 11.10) for development. There, the WLS works out of the box, even with 64-Bit libraries.
Thank you for your help.

Could not complete the command because of a problem using the Adobe Color Engine
Hi all
This bizarrely started this morning - completely out of the blue - and I've no idea why.
Setup: Mac 10.8.2 / Creative Suite Premium PhotoShop CS5 extended (patched to 12.04)
Am working on images exported from LightRoom 4 (16bit A3 Pro Photo RGB PSDs) in PhotoShop CS5.
As part of my image grading process I have a PhotoShop Action that does the following: copy layer to new document (document respects all of copied layer settings) > Image > Adjustments > HDR toning > apply a certain HDR preset > copy to resultant image back to original doc > set opacity as 40%.
Totally out of the blue, after having this action for about 2 months, this morning I start getting a warning dialog of "Could not complete the command because of a problem using the Adobe Color Engine" and the action fails. The failure seems to take place at the 'make document' part of the action and seems to somehow be related to the contents of the clipboard.
I've tried trashing and re-creating the action. It works first time out fine and then - on the next image - errors again.
At present I can only safely carry out the work 'manually' by completing all the actions myself.
I can think of no settings that have changed and the OS hasn't been updated in a while.
I have found one other thread on a similar problem in PhotoShop Elements, but no definitive solution.
Any help appreciated as I have a shedload of stuff to process.
Best wishes
TPOK: trash of prefs didn't work. Tried thrice. Re-created orig action. same problem.
BUT!
Your 'Image > Duplicate' suggestion does seem to work. If I use that in a new action as the method for creating the HDR version doc (instead of 'Select > Copy > New > Paste), it seems to work.
Will try that out this afternoon, but for now: WIN!
Many thanks for the suggestion!

Problems with extended features. I can no longer fill out my documents in the fields provided. The error message I get is "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for original version of this document."
Yes. I don't have the version you pay for. I also tried the free version
of EchoSign. Maybe that caused the problem.
Any more suggestions would be greatly appreciated.
