Ok, I see why it isn't working. I am calling multiple instance of the method therefore it would return a value for each one of them; the last one being false.

The question still remains, how can I manipulate the code so that once a match is found it would return true and stop the recursion?

Thanks,

I am running a traversal of a JTree trying to find a certain node. When I do find that node I want to return true, indicating that I did in fact find it. The code below always returns false indicating to me that even though I return true when the item is found the loop continues to run.

private boolean traverse(JTree tree, TreePath parent, String address) { // Traverse children DefaultMutableTreeNode node = (DefaultMutableTreeNode parent.getLastPathComponent(); if (node.getChildCount() >= 0) { for (Enumeration e=node.children(); e.hasMoreElements(); ) { DefaultMutableTreeNode n = (DefaultMutableTreeNode)e.nextElement(); TreePath path = parent.pathByAddingChild(n); if(n.toString().substring(2).equals(address)) { System.out.println("Match Found!"); return true; } traverse(tree, path, address); } System.out.println("No Match Found 1"); return false; } System.out.println("No Match Found 2"); return false; }

Here is the print out of the test code.
Match Found!
No Match Found 1
No Match Found 1
false <------- a printout from what is returned.

Any ideas?

Hello,

I am having trouble with scrolling a JPanel. When it displays the JPanel it is scrolled all the way to the bottom and I can't seem to find a method where I can force the initial location of the "knob" on the Scrollbar.

Here is how I implement the JPanel
JScrollPane scrollPane = new JScrollPane(); scrollPane.getViewport().add(rightPanel); jSplitPane1.setRightComponent(scrollPane);

I am using a GridBagLayout for the JPanel where I place some buttons and text. Right now I am doing an uber-ugly hack where I place a empty JTextArea at the very top of the JPanel and set the caret position to 0 on that component, but what is the reason it is scrolling all the way to the bottom?

Thanks,

Anyone know how to change the active title bar color of a jinternalframe. I have looked everywhere and the only thing I found was something like...

try
{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
UIManager.put("activeCaption", new java.awt.Color(255,225,255));
SwingUtilities.updateComponentTreeUI(this);
} catch(Exception e) {System.out.println("Error setting native LAF: " + e);}

I have tried implementing this... its changes the overall L&F but does not change the specific color of the active title bar..


Any Ideas?

DefaultTableModel supports JComboBox just not the way I wanted, you were right, I had to create a CustomTableCellRenderer in order to do the job...Thanks!

That is what I was looking for, thanks!

How in the heck do you change the color of a selected titlebar in a jinternalframe. I have serioulsy looked EVERYWHERE. I have tried changing the l&f using UIManager.put but I must be using the wrong name because it won't change, and I have tried many many different names.
Anyone know a way to change it? And if you do use UIManager can you specify the name of the object please?
Thanks,

Is there anyway to display a jcombobox in a jtable and still have it look exactly like a normal jcombobox.
The problem is my users won't know its a combobox if the arrow isn't there initially. Is there anyway to put an arrow there even if the user doesn't click on the box.

Ya....it was just bad programming.....

Have you tried making the tree expand on loading of the jtree?

perhaps something like this?
jTree.expandPath(new TreePath(root.getPath()));

I am guessing you have an action attached to validate the zip code? Why don't you add to that action?

If zipcode is valid, then pull stuff out of database and put into approriate fields.
I may be misunderstanding what you are trying to ask...

I am having the problem of an actionListener duplicating, or perhaps an error in my code. When ther user clicks the arrow_left1 button it move nodes from one tree into the another. When they click the save1 button it saves the current information. The problem comes when I try moving stuff over after I have saved the information. For some reason it duplicates itself. The first time I click save it duplicates once, the second time...twice etc....

relevant code is below....
//if save button is pressed
save1.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent event) {

arrow_left1.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent event) { DefaultMutableTreeNode node = (DefaultMutableTreeNode) Release_jTree2.getLastSelectedPathComponent(); System.out.println("got here"); int count = 0; if(node == null) return; DefaultMutableTreeNode new_node = new DefaultMutableTreeNode(node.toString()); for (Enumeration e = root1.depthFirstEnumeration() ; e.hasMoreElements() :wink: { if(new_node.toString().equals(e.nextElement().toString())) { count ++; JOptionPane.showMessageDialog(null, new_node.toString().substring(2) + " has already been added.", "Error", JOptionPane.ERROR_MESSAGE); return; } } if(node.isLeaf()){ tree1.insertNodeInto(new_node, root1, root1.getChildCount()-1); } else { for(int x = 0; x < node.getLeafCount(); x++){ new_node.add(new DefaultMutableTreeNode(node.getChildAt(x).toString())); } tree1.insertNodeInto(new_node, root1, 0); } for(int x = 0; x < root1.getChildCount(); x++) { for(int y = 0; y < root1.getChildAt(x).getChildCount(); y++) { for(int z = 0; z < root1.getChildCount(); z++) { if(root1.getChildAt(z).toString().equals(root1.getChildAt(x).getChildAt(y).toString())){ JOptionPane.showMessageDialog(null, root1.getChildAt(z).toString().substring(2) + " has been removed because the " + root1.getChildAt(x).toString().substring(2) + " folder already contains the entry.", "Notice", JOptionPane.ERROR_MESSAGE); tree1.removeNodeFromParent((MutableTreeNode)root1.getChildAt(z)); } } } } Release_jTree1.expandPath(new TreePath(root1.getPath())); } });
Output:
got here
got here

On one click of arrow_left1 after saving got here is printed out twice... Any reason why it would be doing that?

Can you add a mouselistener of sorts to a tab? What kind of listerner would that be?
