How to fully collapse a JTree

This may be another easy question, but I can't seem to figure this out. I tried this:
tree.collapsePath(tree.getSelectionPath());but it didn't work :(
Thanks for your help!

I'm guessing at what the vague term "didn't work" here might mean: that line of code collapses all the nodes on a path from the root to a single node but it doesn't collapse any nodes that aren't on that path. And I don't think that was what you wanted, but I'm just guessing at what "fully collapse" means.

How do I collapse multiple libraries into one library?

I have a couple of dozen libraries, created over multiple versions of FCP, and now I have equivalent copies of events and resources strewn across multiple library files across three drives. Plus, FCP has been automatically creating new instances of projects and storing them in files named with dates; I can't find the latest version to open it!
How do I collapse all these libraries into one? Hopefully not by moving event by event from one to another! It takes a couple of minutes per event and resource; the program keeps wanting to "reload" resources after each move.

It looks like you updated your libraries multiple times. Yes, the only way to consolidate them is to drag the events from each library into a master library.

How do I collapse all uncollapsed folders

I have an issue that I have tried to tackle a couple of times as I learn to optimize my mac. Advance apologies to anyone that has helped in the past but I can't seem to get this to work.
I would like to be able to collapse all folders throughout a Finder window. By which I mean to say I wish to select a folder and uncollapse all the contents and then do this to a number - say twenty - of other folders and all their subfolder contents.
Right now I have to collapse each folder individually - which means I have to do this twenty times to get back to a fully collapsed state.
I seem to have tried CMD, OPTION, CTRL, SHIFT and a number of other keyboard commands while collapsing one of the folders but it only seems to collapse the one folder.
It doesn't seem like proper form to have to either run around and close each folder individually or alternately to close out of the Window completely and have to then find where you were at to open a new Finder window with all contents collapsed....
Thanks for any help.

Hi. Many thanks. I think this is where things broke down last time I tried to get this to happen and I got sidetracked with other issues.
While holding down the option key, press the right arrow button.
this expands all the folders.
I get this behavior.
The when you're ready to close those folders. Hold down the option key and press the left arrow.
I don't get this behavior...
Anyone have any ideas? It is actually much more important for me to get the second behavior explained here than it is to get the first.
Thanks Chop....

How to fully delete an aplication

I would like to know how to fully delete and application from my MacBook Pro including the little folders that came with the application that usually stays in the system

This depends on the application. Some applications require an installer, and those applications should also include an uninstaller. Such applications should only be removed using that uninstaller.
Other applications may not have an uninstaller, and you simply drag them into the Applications folder. Those can usually just be dragged to the trash. This will leave their preferences and other things behind, but those things are generally not worth the trouble to find and remove. However, if you really want to find them, hold down the option key and choose Library from the Finder's Go menu. In the folder that opens, look in the Preferences folder (typically for a file named something like "com.companyname.appname.plist") and the Application Support folder. Just don't mess with anything else while you're in there, or you can mess other things up.
For applications downloaded from the App Store, you can open LaunchPad and then click-and-hold on the icon of the application you want to remove. When the icons start "wiggling," an X will appear on the top left corner of the ones that can be safely removed from there. Click that X to remove the app.
Edit: Note that my answers are based on the assumption that you are using Mountain Lion (Mac OS X 10.8.x), as indicated by the forum you posted in, and not Tiger (Mac OS X 10.4.x) as indicated by your profile. If this assumption is incorrect, you would do better to post your question in the Tiger forum.

how to Fully restore Nokia E5 ?
I have tried all the codes of restoring(soft restoring)(deep restoring) but only settings are being restored not the complete phone data
my phone has become very lazy...now tell me how to completely restore it ???

There is no known three key depressed power on combination for E5-00, but surprised that *#7370# doesn't not achieve what you require; as pointed out the next step would be to have device firmware completely re-installed.

Jtree - how do I make a Jtree to expand fully

I am creating a JTree dynamicly and I want the JTree to show up at first fully expand. I am trying to use the expandPath method by I have a problem with the TreePath parameter that it needs to receive. How do I do it?
Thanks

I believe the default renderer calls toString() on the node which for DefaultMutableTreeNode calls toString() on the userObject in the node.
I'm assuming your nodes are printing out what looks like a bunch of garbage like "java.lang.Object$712cfe" (which is actually the id of the object).
You can do 1 of 3 things (I think):
1. Define your own toString() in your node class to return whatever you want.
2. Overwrite the toString() in the object you are using to create the tree node.
3. Write a tree renderer to return the value you want.

How can i refresh a jtree using DefaultMutableTreeNode?

I already create a jtree using DefaultMutableTreeNode, and i also could implement to it the addMouseListener to do a action when the user press every node......Also i used the following instruction to remove all nodes: root_tree.removeAllChildren(); and it instruction remove all the nodes....but when i :
fill the tree
compile my program
i see the tree in my jpanel....it is Ok!
now.....
fill the tree
remove the tree
compile my program
i see only the root (this i wish) it is Ok!
But now i would like that after that i press a combo element (in the actionperformed method):
remove the tree
fill the three with the new nodes
show the tree
But my tree always is the same :(......is like it to need a repaint ....but i already implement it...but i obtain the same result.....
Do somebody have any suggestion...or idea how i can do a refresh in my jtree?....
Anybody could help me please?
Thanks in advance.....

Construct your tree like this:DefaultMutableTreeNode rootNode = xxx;
DefaultTreeModel model = new DefaultTreeModel( rootNode );
JTree tree = new JTree( model );When you update the root node, just tell the model to fire the appropriate change event by doing this:model.reload( rootNode );or this:model.nodeStructureChanged( rootNode );or this:model.setRoot( rootNode )

How to rename node in JTree?(URGENT)

Hi,all:
I am facing a renaming problem in JTree. After I rename, the node still remain the old name, Could anybody tell me why and how to solve it?
The piece of code is as follow:
JTextField textField = new JTextField();
newDndTree.setCellEditor(new MyCellEditor(newDndTree,textField));
newDndTree.setEditable(true);
class MyCellEditor extends DefaultCellEditor {
private JTree tree;
public MyCellEditor(JTree tree, JTextField text) {
super(text);
this.tree = tree;
public boolean isCellEditable(EventObject e) {
boolean rv = false; // return value
if(e instanceof MouseEvent) {
MouseEvent me = (MouseEvent)e;
if(me.getClickCount() == 3) {
TreePath path =
tree.getPathForLocation(me.getX(), me.getY());
if(path.getPathCount() == 1) // root node
return false;
DefaultMutableTreeNode node =
(DefaultMutableTreeNode) path.getLastPathComponent();
Object hitObject=path.getLastPathComponent();
if(hitObject instanceof TreeNode)
return (((TreeNode)hitObject).isLeaf());
return (false);

Hi,all:
My problem is it doesn't rename the node, the node remain the old name.
My piece of code as follow:
//Set Cell Editor
newDndTree.setCellEditor(new MyCellEditor());
//inner class MyCellEditor
class MyCellEditor extends DefaultCellEditor {
public MyCellEditor() {
super(new JTextField());
public boolean isCellEditable(EventObject e) {
if(e instanceof MouseEvent) {
MouseEvent me = (MouseEvent)e;
if(me.getClickCount() == 3) {
JTree tree = (JTree)me.getSource();
TreePath path = tree.getPathForLocation(me.getX(), me.getY());
if(path.getPathCount() == 1) {
//System.out.println("Root");
return false; // root node
DefaultMutableTreeNode node =
(DefaultMutableTreeNode) path.getLastPathComponent();
Object hitObject=path.getLastPathComponent();
if(hitObject instanceof TreeNode) {
TreeNode t = (TreeNode)hitObject;
boolean b = t.isLeaf();
if (b) {
//System.out.println("Leaf");
return (((TreeNode)hitObject).isLeaf());
//else System.out.println("Not Leaf");
// System.out.println("Exit");

}this is the code which i was trying to execute.
here i want to explain you is
when i click the node the icon should change to open_icon
when i click the other node the previous node icon should change to close_icon

How do I get a JTree to display a String?

I'm fiddling around with JTree right now, but I want to be able to format the display string in the table.
When I create a new item, I want that item to be listed as Item 2, or Item 3, in the tree. How can I do that?
How do I change the display string of the TreeNode holding the object, without altering the actual object?
PS: JTree looks so horribly complicated and outdated, did Sun release any newer implementations of trees yet?

It certainly looks modular...I don't doubt that...
But its so complicated to achieve even the simplest of tasks. Perhaps a few more convenience methods or basic implementations should be provided?
Anyway, I've read up on TreeCellRenderer and it seems like it can handle what I want (change the displayed string), it also seems like I need to create my own renderer. Now doesn't that sound like a bit too much work when I all I want is for it to paint "Item 2" instead of "Item@5124f20" ??

How to Expand/Collapse Select Option Tray

Hi,
I have a View in which I have dynamically created a select-option Tray and then added select-options within the Tray using:
DATA lr_cost_ctr            TYPE REF TO data.
DATA lr_interfacecontroller TYPE REF TO iwci_wdr_select_options.
DATA lr_select_options      TYPE REF TO if_wd_select_options.
* Initialise the selection screen.
lr_interfacecontroller = wd_this->wd_cpifc_select_options_search( ).
lr_select_options =
           lr_interfacecontroller->init_selection_screen( ).
* Add a tray.
lr_select_options->add_block(
    i_id           = 'TRY_ACCT_***'
    i_block_type   = if_wd_select_options=>mc_block_type_tray
    i_title        = 'Account Assignment' ).
* Add a Select Option.
lr_cost_ctr = lr_select_options->create_range_table( 'KOSTL' ).
lr_select_options->add_selection_field(
    i_id              = 'COST_CTR'
    i_within_block    = 'TRY_ACCT_***'
    it_result         = lr_cost_ctr ).
This works fine, but how do I dynamically expand and collapse the select-option Tray ? There are plenty of examples for expanding/collapsing normal Trays by binding the "expanded" attribute at design time or dynamically. But with a Tray created as a select-option block I do not have a reference to the Tray.
I have searched high and low but cannot find how to do this.
I don't want to create the Tray at design time because there will be select-options above and within the Tray.
Any help will be appreciated.
Thanks & regards,
Grogan

Hi,
My Approch is:
---Initially set the webBean property in processReq
Hgrid.setAutoQuery(false);
---On Button click navigate to the same page n set the webBean properties..
put var in session.
pageContext.forwardImmediatelyToCurrentPage(null, true, null);
---in process req get teh value of var from session.
if(pageContext.getSessionValue(var)!= null)
Hgrid.setAutoQuery(true);
Hope it will helps..:)
Note:
---We cant modify the webBean properties in processformReq and processformdata.

How do I collapse audio tracks

I'm in FCP X 10.1 and can't figure how to collapse the audio so the black line is remove above the track so I can do cut without getting out of sync (see right side of image). Here's what it looks like. PS what is the view called and how did it happen.

Are you talking about this black bar?
You can't remove that. It's the shelf that connects the secondary storyline that's created when the audio cross fade transition is applied. It connects the two pieces of audio that were separate connected clips, connected to the multicam clip on the primary storyline. It looks like you detached the multicam clip audio from the multicam clip.
