JTree hide Path

Hello,
I am using jTree to show folder named c:\Test, It has many directories & subdirectories. I would like to hide path & only name to be displayed.
C:\Test
c:\Test\folder1
c:\Test\folder2
c:\Test\Folder3.
c:\Test\Folder3\Folder31
I need display like this:
Test
Folder1
Folder2
Folder3
Folder31
How to do that??? Any Ideas.
Thanks

JTree Hide Show nodes

Hi All
I have a JTree, and would like to hide some tree nodes based on a certain path, i have been using the setFilter and I can't seem to get to work.

JTree - hidding root when showing the rest of the tree

How can I hide only the root element when displaying the rest of a tree ?

Hi Zauz,
I unterstand your argumentation, but I have a problem with the implementation. Maybe you can show me your answer at a simple example:
DefaultMutableTreeNode root = new DefaultMutableTreeNode("world");
DefaultMutableTreeNode country1 = new DefaultMutableTreeNode("france"); // Chield 1
DefaultMutableTreeNode country2 = new DefaultMutableTreeNode("germany"); //Chield 2
DefaultMutableTreeNode country3 = new DefaultMutableTreeNode("norway"); //Chield 3
DefaultMutableTreeNode town1 = new DefaultMutableTreeNode("Frankfurt");
DefaultMutableTreeNode town2 = new DefaultMutableTreeNode("Berlin");
JTreetree = new JTree(root);
root.add(country1);
root.add(country2);
root.add(country3);
country2.add(town1);
country2.add(town2);
tree.expandRow(2); // 3 countries -1 = 2 children ????
tree.setRootVisible(false); // result 0 tree invisible ???

Hide path info in the brower url

Hi, all.
I've search all over this forum but couldn't find a solution to my problem. I have a website hosted with JRun and IIS. What I want to do is that when users surf from page to page within my site, the url will always show only the domain name instead of domain:port_no/index.html.
Now I can make the url remains the same by using frames but it's always shows the url of first page, something like this: http://www.mydomain.net:8100/mypath/index.html.
What can I do to remove the port and path info from this url? i have no idea which i should change, the IIS settings or the JRun settings or even the JSP?
Please help if you got any idea. Thanks a lot.

Hi,
I created one frame based test website with three frames. One top, left and the main frame.
I tested with some sample pages and its working fine and i came to know that i missed to tell somthing.
First i want to know the frameset's file name. If the frameset's filename is index.html then there is no problem. Other wise try to load the frameset instead of index.html as default file in the IIS website's properties.
I have no problem with my frames. It will show only the www.domain.com in the address bar. I tested it with several subdirectories with sample html pages. it works fine and upto my last page it shows only the www.domain.com only.
If the problem occurs again, give me the code of ur frame set.
Sundar.

Confusion building JTree from path strings

If I have a bunch of strings like this:
"/dira/dir1/file1"
"/dira/dir1/file2"
"/dira/dir2/file1"
"/dira/dir3/anotherdir/file1"
etc.
Does anybody have an easy solution to getting them in a JTree that looks like this:
   dira
    |
    +-dir1
    | |
    | +-file1
    | |
    | +-file2
    |
    +-dir2
    | |
    | +-file1
    |
    +-dir3
       |
       +-anotherdir
          |
          +-file1Mainly I am having trouble getting the tree to populate without duplicating nodes. For example dir1 gets listed twice. I am looking for a solution that will parse these strings and build the tree. I have found demos that read a file system, but nothing that works with strings. I have tried to pick apart the file system demos, but so far I can't get it to work correctly.
Thanks,
Jeff

Expand a path in JTree

Hi all. Please help, I am trying to programmatically expand JTree with JTree.expandPath(path), but it only works one level downwards from the last physically selected node. Is this a bug, or am I doing something wrong?

If you are using DefaultMutableTreeNode for your nodes, thenTreePath tp = new TreePath(theNode.getPath());gets you a path from the root to theNode. If you want that to be the selection, thentheTree.setSelectionPath(tp);and if you want it to be expanded and viewable thentheTree.expandPath(tp);If you aren't using DefaultMutableTreeNode, you will have to build the TreeNode[] that contains the nodes from the root down to theNode by some kind of loop; the rest of the code still works.

Problem with JPopupMenu and JTree

Hi,
Is there any way to have different JPopupMenu for every node.
When I right click on the treenode there is popup menu have a "*JCheckBoxMenuItem*". By default the value of that checkbox is false. Now when i try to right click on a particular node and select the checkbox the selected value gets applied to rest of all nodes also.

How do you see the path in Yosemite?

How do you see the path in Yosemite? What is the command to reveal the path to any given file? Is it somewhere in Finder?

This is even better:
Open the Terminal application
Enter the line below exactly as it appears (Copy/Paste may/not work: highlight the line of text > switch to the Terminal app > cmd-v):
defaults write com.apple.finder _FXShowPosixPathInTitle -bool TRUE
*Note: there are single spaces after 'defaults', after 'write', after 'com.apple.finder', after '_FXShowPosixPathInTitle', and after '-bool'
Then hit enter
That's it! Go ahead and Quit Terminal (cmd-Q).
Now:
Close any Finder windows you have open.
Open a new Finder window, and it should look like this:
You can then get rid of the path bar at the bottom:
Finder Menu > View > Hide Path bar -- or just use the keyboard-shortcut: cmd-opt-P

Path Layer Deselecting after Making Selection

Hello,
As I use this tool for multiple fast renderings, I love to use the Path Selection tool to modify the selection as such in quick succession. However, it seems as though after my slection is made, usign the path, the path layer disappears, needing reselection in the Path Window to do so. Here's what happens:
Step 1
I my paths, in which I want to first select this box, and then combine them at differing feather overlays. So naturally, I select the center most item, and...
Step 2
Up comes the dialog box as normal. I set the feather, hit enter and...
Step 3
Where did my other paths go?!?!
Step 3 (Previous to CC, at least in CS5)
Here I had the option to grab another path with my tool, overlap a feather at a different amount. Why does this happen?
Is there a way to revert the tool back to the CS5 way of Selecting? Please let me know, thanks.

I believe your paths are still there, if i look at the path's palette.
When you deselect the path in the path's palette, no path will be visible in the stage. Try adding fill color and see.
Step 01 and 02, your path was still selected in the path's palette but in step 03 it wasn't. Once you made the selection click on the path in the path's palette and see if it is visible or not.
Check my tutorial on 'How to hide the path when adding layer style'. If the path is not selected in the path's palette, then it looks like it is not there.

Reload JTree and keep expanded nodes

Hi all,
I have spent some time looking around on this, found some useful stuff, but I still cannot seem to get a result.
Here is my situation:
I have a JTree for a GUI desktop app. I build the tree from a database file. The user has the ability to refresh the tree to keep it in sync with any database changes. The problem is that when I refresh, all the nodes that were previously expanded are now collapsed again.
Having looked around, I have seen a lot of JTree.expandRow() answers, but I don't want to use expandRow, as the rows will changes according to any db changes.
I thought a good solution would be to trap any expand or collapse events and for each either add or remove the TreePath for the relevant node onto a List. When the users refreshes the tree, I thought I could run through the list and expand any TreeNodes I find. I also found someone advocating such an approach in another thread. BUT - it doesn't work for me Here is the code for my refresh. Any help/advice, greatly appreciated.
Thanks in advance,
Steve
private void refreshBrowser(){
        System.out.println("Refresh browser - Started");
        rootTreeNode.removeAllChildren(); // remove all nodes from root
        loadBrowserData(); // This method loads nodes from a database
         Iterator<TreePath> TPI = objectTreePaths.iterator(); // run throught my saved paths
        while (TPI.hasNext()) {
            TreePath yTreePath = TPI.next();
            browserTree.expandPath(yTreePath); // Expand each found path
        treeModel.reload(); // model changed - reload it.
        System.out.println("Refresh browser - Complete");
    }

Here is my situation:
I have a JTree for a GUI desktop app. I build the
tree from a database file. The user has the ability
to refresh the tree to keep it in sync with any
database changes. The problem is that when I refresh,
all the nodes that were previously expanded are now
collapsed again.
Having looked around, I have seen a lot of
JTree.expandRow() answers, but I don't want to use
expandRow, as the rows will changes according to any
db changes.you could use:
JTee.scrollPathToVisible(path);
Where path is obtained in this way from a DefaultMutableTreeNode (TreeNode):
TreePath path = new TreePath(((DefaultMutableTreeNode)node).getPath());
I thought a good solution would be to trap any expand
or collapse events and for each either add or remove
the TreePath for the relevant node onto a List. When
the users refreshes the tree, I thought I could run
through the list and expand any TreeNodes I find. I
also found someone advocating such an approach in
another thread. BUT - it doesn't work for me When you perform a JTree.reload() call, it will collapse each node.
My advice is to call JTree.reload() and then call JTree.scrollPathToVisible(path) for each TreeNode previously expanded.
Hope this can help,

JTree leaf selection

hi guys,
I am developing a jTree for a networking product,which will show all the network elements present in the network.The tree also shows the device status like Up,Down etc.I have provided a button to refresh the jtree to update the status of the devices.But after updating the jtree when i try to expand or setSelected path to previously selected leaf,the jTree is expanding only till the parent of the leaf.Here is the code which i have written:
public void addRootNodes()
          TreePath path=jTree.getSelectionPath();
          DefaultMutableTreeNode selectedNode = (DefaultMutableTreeNode)path.getLastPathComponent();
          TopologyUtilities.getNetworkCollectionDetails();
          TopologyUtilities.getRuntimeDataMapOnRefresh();
          initializeData();
          rootBusiness.removeAllChildren();
          rootNetwork.removeAllChildren();
          rootDiscovery.removeAllChildren();
          addRegionLocationToBusinessView();
          AddNodesToTree.addRoutersToNetworkView(configuredNetworkCollection, dataMap, rootNetwork);
          AddNodesToTree.addRoutersToDiscoveryView(discoveredNetworkCollection, configuredNetworkCollection, dataMap, rootDiscovery);
          treeModel.reload();
          panel.removeAll();
          jTree.setSelectionPath(path);
Thanks for the help in advance
bye,
Srinivas

Since you have a reference to a DefaultMutableTreeNode object, can't you do something like
TreeNode[] nodes = n.getPath();
TreePath path = new TreePath(nodes);
tree.setSelectionPath(path);

Hid interface to Pelouse scale

I've got a client who would like to read weigts from a Pelouze USB scale into LabVIEW. The scale comes with a driver that is based on the HID interface. There are several threads on the forums about talking to USB devices using USB RAW through VISA and on talking to HID devices, but I couldn't find any thread that claimed that the HID idea had been done successfully from LabVIEW.
Although it appears that one can disassociate the device from the HID driver and access it through USB RAW, we have decided not to go that route. (There are too many steps required to set up the scale in this manner. It wouldn't be appropriate for the eventual customer.) So calling HID.dll seems to be the only option. However, my reading of the threads seems to indicate that this is pretty complicated. Even if we understood the hid.dll interface, we still don't have any specs on how the scale uses the hid interface.
Has anyone succeeded in talking to a Pelouze scale from LabVIEW? Or any of the other numerous USB scales that use an HID interface?
Thanks,
DaveT

What do you mean when you say the scale comes with a driver that is based on the HID interface. Is that a DLL? Why would you then want to access HID.DLL instead of this specific driver DLL?
HID.DLL is the generic HID Windows API to all HID devices (that are not captured by the Windows kernel for user events, such as the mice and keyboards). So your scale implements a HID USB class and Windows recognizes that and makes it available as such through HID.DLL. However accessing a HID device through HID.DLL is still pretty low level as you simply get a data stream and need to decode and encode the device specific information from and to that stream. Not to speak of the various hoops you have to jump through to localize and open the device through setupAPI.dll and HID.dll, before you can talk to it. Another problem is that the data stream protocol of proprietary HID devices is seldom documented.
So if your scale comes with a DLL driver to access it, go with that driver. Of course you will need some documentation of the API of that driver and then using the Call Library Node to call into it. Going the direct HID path is really not a good solution unless you know the HID data stream protocol of the device AND you have no other way to do it (for instance if you need to interface to your own HID device design).

JTree.getNextMatch() only works on visible nodes? Any alternatives?

I'm trying to search for and select a node in the tree based on user input. I was trying to use JTree.getNextMatch(), but that method returns a NULL TreePath if the node being searched for is not currently visible (if this is, indeed, the case, why isn't this noted in the API documentation???)
Anyway, is there a method that returns the path of a node, whether visible or not? I could then use that info to make the path visible using JTree.scrollPathToVisible(path).
I found a link at
http://www.exampledepot.com/egs/javax.swing.tree/FindNode.html
that describes various methods, including getNextMatch() - and from the comments in that code, I got the notion that this is only for visible nodes. But I was hoping that since 2003, there have been additional methods in the standard toolkit which I can use rather than manually descend the tree myself.

If you're using DefaultMutableTreeNodes, you can use the depthFirstEnumeration method, API is here: http://java.sun.com/j2se/1.5.0/docs/api/javax/swing/tree/DefaultMutableTreeNode.html#depthFirstEnumeration()

JTree odd click behavior w/ L&F

I have a JTree that works perfectly until I change the L&F. In the mouse down event, once the line of code executes:
UIManager.setLookAndFeel("string");
SwingUtilities.updateComponentTreeUI(root);
(root is the entire JFrame where the tree and the other components lie)
Before this is executed, the tree "leaves" require one click to run my code -- basically updating a JLabel with the current path. This is trapped on the mouse down event.
Afterwards, however, the tree needs 2 clicks before it'll register the current node.
Do I have to update something in the JTree when the L&F are changed?
Thanks --
Steve

Seems like the JTree selection path is the only thing not updating correctly...
This code:
tree.getSelectionPath()
seems to be returning the path right before it -- unless you double click.
Is this a Swing bug?

It works fine for me (after commenting out the part about NodeIconData, whose source you didn't provide). What is the behavior you expect to see but don't? Is it that when you click on a tree node, it doesn't appear "selected?"
Why not extends DefaultTreeCellRenderer? You appear to be doing minimal configuring (sometimes changing the text and/or icon of the node).
     class FSDirectoryCellRenderer extends DefaultTreeCellRenderer {
          public FSDirectoryCellRenderer() {
               super();
               setOpaque(false);
          public Component getTreeCellRendererComponent(JTree tree, Object value,
                    boolean selected, boolean expanded, boolean leaf, int row,
                    boolean hasFocus) {
               super.getTreeCellRendererComponent(tree, value, selected, expanded,
                                   leaf, row, hasFocus);
               DefaultMutableTreeNode node = (DefaultMutableTreeNode) value;
               Object obj = node.getUserObject();
               setText(obj.toString());
               if (obj instanceof Boolean) {
                    setText("Loading");
//               if (obj instanceof NodeIconData) {
//                    NodeIconData nodeIconData = (NodeIconData) obj;
//                    if (expanded) {
//                         setIcon(nodeIconData.getExpandedIcon());
//                    } else {
//                         setIcon(nodeIconData.getNormalIcon());
//               } else {
                    setIcon(null);
               return this;
