How to delete an element in a tree?

how can i delete element in my tree?
after that to refresh the tree?

OK. You should have the rootNode and then your three other nodes added to the root (fiche, famille, etc)?
I'm currently creating an application that uses a tree with two branches. The code I posted works regardless of the branch the node I wish to remove belongs to.
It does depend as well how you are storing your nodes. I mean I'm just storing the node referenced by a string in a hashtable for easy reference. I gather that you want to click the node for it to disappear?

How to delete an element in an array...(simple way)

hi,
Newbie here... please help how to delete an element in an array list?
there are alot of codes but they're complicated for a newbie like me..
(simple codes would be better ..:) thank you...

i think u got..what i'm saying.
thnx..Mak,
Say we wish to delete the second element of an array a[1]. Do you really believe that a[1] = a[2] somehow magically deletes a[1]? I really don't think so Tim.
Two eggs, minus 1, equals two eggs? Interesting theory, but I think you're probably wrong.
*@OP:* My advise is just use an ArrayList.

Delete an Element in the Tree

Hi,
I would like to delete an element in the tree.
but I was able to delete only the rootNode
Could you help me. thanks
IPrivateTreeView.ITreeNodeNode rootNode =
     wdContext.nodeTreeNode();
IPrivateTreeView.ITreeNodeElement level2Delete = null;
level2Delete = rootNode.currentTreeNodeElement( );
// I would like to do somethink like that
level2Delete.REMOVE_ELEMENT

Hi Philippe,
it's sooooo easy This is a snipped from the IWDNode API
   * Removes an element from the node collection. If an ICMIObservableList is
   * bound to the node, this list is modified!
   * @param element The element to be removed
   * @return <code>true</code> if the element was in.
boolean removeElement(IWDNodeElement element);
so you simply have to call
wdContext.nodeTreeNode().removeElement(level2Delete);
Hope that helps.
Regards

HOW TO DELETE DUPLICATE ELEMENT IN A VECTOR

Hi everybody!
If I've a vector like this vectA={apple,orange,grape,apple,apple,banana}
and I want final result be vectB={apple,orange,grape,banana}.
How should I compare each element in vectA and delete duplicate element. Like here duplicated element is apple. Only one apple remain in the vectB.
Any help,
Thanks.

Hello all. Good question and good answers, but I would like to elaborate.
To begin with, you specifically asked to map the following:
{apple,orange,grape,apple,apple,banana} ==> {apple,orange,grape,banana}
Both of cotton.m's solutions do NOT do this, unfortunately. They are both useful in particular cases though, so think about what you're trying to do:
cotton.m's first solution is best if order does not matter. In fact, as flounder first stated, whenever order doesn't matter, your most efficient bet is to use a Set instead of a List (or Vector) anyways.
Set vectB = new HashSet(vectA);This code maps to {banana, orange, grape, apple}, because HashSets are "randomly" ordered.
cotton.m's second solution is good if you want to impose NEW ordering on the List.
Set vectB = new TreeSet(vectA);This code maps to {apple, banana, grape, orange}, because TreeSet uses alphabetical-order on Strings by default.
java_2006, your solution is the most correct, but it's a little verbose for my taste :)
more importantly, the runtime-efficiency is pretty bad (n-squared). calling Vector.contains performs (at worst) n comparisons; you're going to call it n times! Set.contains usually performs 2 comparisons (constant, much better), so I suggest you USE a Set to do the filtering, while still sticking with your good idea to use a List. When the ordering is "arbitrary" (so can't use TreeSet) but still relevant (so can't use HashSet), you're basically talking about a List.
I think saving A LOT of time is worth using A LITTLE extra space, so here, let's save ourself some runtime, and some carpal-tunnel.
import java.util.*;
class Foo {
     public static void main(String[] args) {
          String[] fruits = {"apple","orange","grape","apple","apple","banana"};
          List     l = Arrays.asList(fruits),
               m = filterDups(l);
          System.out.println(m);
     // remember, both of the following methods use O(n) space, but only O(n) time
     static List filterDups(List l) {
          List retVal = new ArrayList();
          Set s = new HashSet();
          for (Object o : l)
               if (s.add(o))
                    retVal.add(o);     // Set.add returns true iff the item was NOT already present
          return retVal;
     static void killDups(List l) {
          Set s = new HashSet();
          for (Iterator i = l.iterator(); i.hasNext(); )
               if (! s.add(i.next()))
                    i.remove();
     // honestly, please don't use Vectors ever again... thanks!
     // if you're going to be a jerk about it, and claim you NEED a Vector result
     // then here's your code, whiner
     public static void mainx(String[] args) {
          String[] fruits = {"apple","orange","grape","apple","apple","banana"};
          List l = Arrays.asList(fruits);
          Vector v = new Vector(l);
          killDups(v);
          System.out.println(v);
}

XMLBeans - how to delete an element?

Guys,
How do you delete an element within an xml data element?
If there's more than one way what are they?
Currently, I've generated XML java objects. I see a setNil() method and a couple removeXXX methods but neither appear to delete the element I'm trying to give the axe to.
Thanks!

How to delete an element in arraylist??

here i have an array list which contain details of an address book
I want to delete one element in the list
but its not deleting
Could anyone please take a look and help me
tank u in advance!!
else if (X.compareTo(F)==0)
   {System.out.println("Pour supprimer une fiche : saisir le NUM INDEX.");
    Integer c1 = new Integer(0);
    Z = clavier.readLine();
    c1=Integer.valueOf(Z);
    System.out.println("Vous allez supprimer la fiche "+c1);
    for( Iterator it= l.iterator(); it.hasNext();) {
      Object p =it.next();
      relations R=(relations)p;
        if (R.getnumero()==c1)
       l.remove(l.indexOf(p));}
      for( Iterator it1= l.iterator(); it1.hasNext();) {
         Object o =it1.next();
         if (o.getClass().getName()=="carnetadresses.contact")
           ((relations) (o)).affiche();
           }break;
}

It's a good thing you use code tags for posting here. Could you now consider using code conventions?
- Why is the second loop nested in the first one? (this second loop looks weird anyway...)
- The Iterator has a remove method. You should use it in such case.
- Looks like you have a malpositioned/misused break statement (which is probably the reason why nothing happen, as it terminates the for loop after the first iteration.)

How to delete empty element in popup list

I have a question about a suspicious behaviour in Forms Builder 10.1.2.0.2.
When I have a list object (pop up list) I can define some values in the attribute palette of the object.
So you can set a shown name and a value behind. In this little window to set the items of the popup list you get automatically a white empty item at the end of the list. When I click now on this empty item (you do so, when you want to add an item) Forms Builder automatically adds an new empty item at the end.
When I click this new empty item, Forms Builder adss another empty one ... and so on.
It´s very suspicious because, when I end this dialog with "OK", it will be saved and when I open the form (over web) I have at the end of the list one, two (or more) empty elements in list.
But I can´t delete this empty ones from the list in Forms Builder.
So my question:
how can I delete empty items in a popup list??
I try it with hit "del" button at keyboard or delete the set value for the item (I hope Forms Builder delete items without value). But all does not help.

Thanks jwh for this great solution! :)
On my german keyboard it is:
ctrl+< for deleting a line
ctrl+> (= ctrl+shift+<) for adding a new line
Thanks! :)
I have another question (you can maybe help me, too?).
On this popup lists you can have several items. When you open a form (via web) and the list has more than x items (maybe 5 or 6) the form shows a scroll bar on the right side.
Is there any poosibility to set how much items has to show and only show a scroll bar when there are more items in the list?
Or other way: set the maximum of shown items so big, that there will be no scroll bar.

How to delete su-elements in "System Preferences/Others"

I'm trying to delete a doubled element (done by mistake) inside an application located in "Other" within "System Preferences"
More precisely:
- I've "USB overdrive" app control on this location: "Other"
- By error, whoever it is, in "Status" window, there are two "USB Receiver" lines
How can I delete one of those?

In System Preferences, right-click on one of them and select Remove.
I'm not sure how that will affect the other. If two status menus are still there, cmd+drag one off the status menu area.

How to delete form elements in Muse

I followed the instructions I found on-line but am unable to remove an item from a form in Muse. There is no option for deleting elements, i.e.: a name or phone field. Either, it's a hidden feature or I totally missed it.
Christian

Tanks for your reply. Unfortunately that doesn't work, that was the first thing I tried. I understand the field is selected once it shows the blue arrow in the top right corner, but hitting "delete" produces no action. And no right click will give me the "clear" or "delete" option. Even using the top menu bar has the actions"cut", "copy" and "clear" greyed out...
Some on-line info suggested to click on the "trash can" in the top right corner and confirm "delete".... nothing like that in my version. I am using the most current version of Muse, could it be a bug?
I know I can redo it by starting with the simple form and add extra fields (that works) but I should not have to do it the long way...
Thanks,
Christian

How to delete conext entries in JNDI tree after undeployment?

Hi,
When I deploy an EAR or JAR file with EJBs, they bind in the JNDI server.
When I undeploy the application the beans are no longer bound to the JNDI
tree, but the contexts they created remain.
For example, I deploy a bean that binds its home object to the following
entry in the JNDI:
myapp/mymodule/MyBean
When I undeploy MyBean, the context myapp/mymodule remain.
Is there an utility to remove these entries or do I have to develop my own
utility? I did not find anything in the administration console to do this.
This has been a source of some trouble, because sometimes I get error
messages when I want to redeploy the beans.
Thanks in advance,
Vegeta

Please don't cross post. see my reply in the ejb newsgroup.
Thanks,
Michael

How to delete an element from a template??

I bought a dreamweaver template and there's a menu that goes across the top of the screen but I don't know how to get rid of it?? I don't see any coding for it in dreamweaver it just kinda shows up. Link to page: http://ramclutches.com/newsite/index.html

This is not a DW template child page, so all the code that is rendered on the screen is also editable by you. Add this rule to your CSS -
#advanced .bg_pro {
display:none;
and that top menu will be gone.

How to delete a UI element in a "safe" way?

When I delete/cut/copy a UI element from a project.
I cannot rebuild/archive the project due a "classpath" problem.
The project's structure is damaged and a lot of errors are generated.
1) How to delete UI elements from the layout without damage the project's structure?
2) If the project's structure is damaged. Is there an easy way to fix it?
(I tried the "repair" option from project name's context menu - didn't help).
Also, I tried to "organize imports" - didn't help either.
http://img67.imageshack.us/img67/4927/errors0ph.jpg
Thanks, Omri

Well, failing everything else, there is a way to do this if you have deleted an element and the project has become damaged.
In your Windows file explorer, browse to the project directory, search for and delete all the ".class" and ".java" files. Now browse through all the project subdirectories, open every file in Notepad, and search for references to the object which you deleted, and delete those references.
You need to be really careful when you do this, because you can totally ruin the Web Dynpro project. But if done correctly, it can revive a project which has run into the problem which you describe.
