Delete a node from JTree using removeSelectionPath question

hi guys,
how do i delete a node using removeSelectionPath?
jtree.removeSelectionPath(treePath);
it dont seem to work
cheers

Each of that type of learning interactions has a minimum and a maximum number of buttons (nodes). For the circle matrix I found a minimum of 5 (central + one ring). When you select one of the buttons you should see a minus sign that allows to delete a button.

Cannot Delete CPTL file from Desktop using Vista

Hi All,
I cannot Delete CPTL file from Desktop using Vista. Explorer
crashes. It is a Captivate 2 file.
I have tried (with no luck):
- logging in as a different user and deleting the file.
- running explorer as an Administrator
- uninstalling Captivate.
Anyone got any ideas?
Cheers,
Raef

Hi Raef,
That is a strange issue. Here are a couple more ideas you
could try:
- Have you tried renaming the file (including suffix)?
- Have you rebooted?
- Do you get any error messages when trying to delete, such
as "Acess Denied"?
- Is your machine networked? Is it possible someone else has
the file open?
- Can the file be moved to another location or put in a
folder (and then deleted)?
- Have you tried using the Command Prompt / DOS mode to
delete the file?
It sounds like it could be a Vista issue so I would look at
the Microsoft Vista forums too. Sorry I do not have an exact
answer.
IHTH,
Aaron

How to delete an operation from order using the bapi

Can somebody please tell me how to delete an operation from order using the bapi
BAPI_ALM_ORDER_MAINTAIN.
Following was the test data for the BAPI.
000000 OPERATION DELETE 0000040052810070
000000 SAVE 0000040052810070
Even I tried entering the operation table. The BAPI control ends fine, but when I check the order using IW32, the operation still exists.
So, can you please tell me where Iam going wrong.

Hi Subash Mohanvel,
Check bapireturn parameter of the bapi BAPI_ALM_ORDER_MAINTAIN after execution of the code , and if there is no error message in the return table then call bapi_Transaction_commit.
Unless you call this database saving of the records/values will not get reflected in the system.
Hope that helps.

How to Remove a Node from JTree?

I want to remove a node from a JTree but the node may or maynot be visible.
My method takes a String which is the name of the node.
The nodes im using are DefaultMutableTreeNode
This is my code so far but it doesnt work.
public void removePerson(String pName)
          TreePath node = tree.getNextMatch(pName,0,Position.Bias.Forward);
          tree.expandPath(node);
          tree.removeSelectionPath(node);
}Any Suggestions or ways which i could achive this?
Thank you,

I don't think removeSelectionPath is what you want to use.
These should help:

How can I remove child node from JTree???

I use the model : DefaultMutableTreeNode
Thanks

There are a couple of ways it can be done. If your tree uses DefaultTreeModel as its TreeModel, you can use removeNodeFromParent(). This will remove the node from its parent and effectively remove its children, too. All nodes removed will be garbage-collected if there are no other references to them.
If your tree model is not the default tree model, but still uses MutableTreeNode, you can use either remove() or removeFromParent() on the node itself, depending on whether you want to remove the node itself or one of its children.
On the other hand, your tree may use a model that simply "mirrors" another data structure, in which case you would have to remove the node from the other data structure and have it reflected in the model.

Code to delete a node from the tab that satisfy the given condition

Hi Experts,
I have a scenario of escalation i.e., Deletion of the message details from the table of a tab when that row of details move to second tab based on status condition. I am unable to delete the escalated row details from first tab.
Can any one provide me the code..
Thanks & Regards,
Priya

Hi Priya,
Let me know whether my following assumption is right or worng !!
You have two tables in different tabs and trying to move some rows from table1 in tab1 to table2 in tab2.But you can;t able to delete the rows in table1 of tab1 ..is that correct ??
You can use wdContext.node<NodeName>().removeElement(IWDNodeElement) to delete a row from a table.
Ex :
wdContext.nodeEmployee().removeElement(wdContext.nodeEmployee().getElementAt(0));
will remove the first element from the node.

How to delete a song from iphone using "itunes 12"

iTunes 12 & iPhone 5s v8.1, iTunes installed on PC with Windows 7
I need to delete some songs from my iPhone. They are not on any playlist. I see no way to delete them using either iTunes or the iPhone.
How do I delete songs from my iPhone using the iPhone OR iTunes?

I also have this question as well. I've done everything from turning off the "show all music" to turning off icloud. After hours of frustration, I decided to delete all music and just re-download the songs i actually want on my phone. Apple makes everything so much more difficult than it has to be. Next time, I'll try the "throw phone at wall" method.

Delete tree nodes from Table

I have created a tree table
create table subforums (
id          NUMBER(5) primary key,
parent_id     references subforums,
name          varchar2(100)
And now i dont know how to delete a tree with a specified id and all of his children.
I tried to find out but i couldnt

Hi,
When you delete a node and all of its children, what do you want to do with the grandchildren? If you want to set their parent_id to NULL, do that in a separate UPDATE statement first, then DELETE the original node and all its remaining descendants, as show below.
If, when you say "children", you mean "descendants" (including
children,
children of children,
children of children of children,
and so on, to any level,
) then do a CONNECT BY query to find their primary keys, and DELETE everything in that list, like this:
DELETE subforms
WHERE   id IN
        SELECT id
        FROM    subforms
        START WITH        id = :specified_id
        CONNECT BY PRIOR id = parent_id
        );

Dynamiclly remove node from JTree

hi all,
I want to remove nodes from a tree dynamically. I used "treeModel.removeNodeFromParent(node);". The node was removed from that treeModel, but the tree never updated. I tried to use tree.repaint() method. It doesn't work. Any suggestion?
thanks a lot in advance.

try with TreeModel.reload(); This will surely work

HT3529 How to recover deleted text messages from iphone using iPhone

I'm trying to recover text messages I deleted on my iPhone4s. Is it possible?
Is it possible to do with out using a computer. If possible I'd like to recover the messages using my iPhone.

If the backup is made after the messages were deleted, then you won't be able to get them back via an iTunes restore. However, you may be able to use a third-party program to look at the backup made after the messages were deleted and see what information about those messages is recoverable.
One program, the one I work on, is called Decipher TextMessage. Our software will scan the text-message database and show you what information (whole and incomplete) was found that has been previously deleted. We've had a lot of success helping folks recover their deleted text messages -- it doesn't always work 100% since we're at the mercy of how the database works but it's worth a shot to see what you can find!
The website for Decipher TextMessage is http://deciphertools.com
You're also welcome to visit our website, try the software free, and send us any questions that you have.
Disclaimer: Since I work on Decipher TextMessage, I stand to benefit from the links to our website that I've made above.
