Tree node roll over

hi all,
I want to create my tree which at mouse roll over any node that node will change its icon and will expand if the node text is greater than the tree width. only the rolled over node will be expanded, exactly like the windows explorer.
Thanks.

Determine if mouse is over tree node

hi.
I recently added some code from this forum on
highlighting a node when the mouse is over it.
I am taking this futher and setting a Border around the nodehowever it draws a border around every node.
I want to only draw the border when the mouse is over the node.
the example i got does this to set the foreground
((JLabel)result).setForeground(Color.red);
i do this to set the border
((JLabel)result).setBorder
(BorderFactory.createLineBorder(Color.black));
i ve tried getting the positions of both the mouse and the jlabel but am having trouble determining if the position of the mouse is within the position of the node in the tree.
Ive used methods like the contains method but it doesnt work for me . can anyone give me a hint as to how to see if the points of the mouse are on the Jlabel?

This is very close to your solution. Last month, I implement ToolTip Text on every Tree Node so when Mouse goes on to the Node, It shows the Tool Tip Text. Have a look at this code and try to change it accordingly.
This code is in the Constructor in your class.

      } catch (Exception ex) {
      // NullPointerException, usually comes at the start of the Application

How to resize a custom tree node like you would a JFrame window?

Hello,
I am trying to resize a custom tree node like you would a JFrame window.
As with a JFrame, when your mouse crosses the Border, the cursor should change and you are able to drag the edge to resize the node.
However, I am faced with a problem. Border cannot detect this and I dont want to use a mouse motion listener (with a large number of nodes, I fear it will be inefficient, calculating every node's position constantly).

}

the node on the tree is only painted on using the
renderer to do the painting work. A mouse listener
has to be added to the tree, and when moved over an
area, you have to determine if you are over the
border and which direction to update the cursor and
to know which way to resize when dragged. One of the
BasicRootPaneUI has some code that can help determine
that.Thanks for replying. What is your opinion on this alternative idea that I just had?
I am wondering if it might be easier to have a toggle button in the node that you click when you want to resize the node. Then a mouse-down and dragging the mouse will resize the node. Mouse-up will reset the toggle button, and so will mouse down in an invalid area.

Does an irrepariable "Invalid B-tree node" = unusable HD?

Hello,
I've decided my external LaCie drive has officially "died," but I want to know if it's truly unuseable or if I can just reformat it and start over (with it) again.
The Drive: a LaCie 300GB with one 40GB scratch partition and one 260GB backup partition.
What happened: After a about a week of erratic/slow disk access to the backup partiton (I'd shrugged it off as a full and fragmented drive), it finally just screeched to a snail's pace - so I could read/write to it, but, for example, copying 5MB file to/from it took about 3mins. I quickly backed up as much as I could off of it to another drive (100GB took 14hrs) and just as it finished copying the last file, it disappeared from my sidebar (though the scratch partition was still visible). I Disk Utility and could see it was unmounted and it's "name" had been reset to "disk5s3". Running the First Aid repair resulted in a quick "Invalid B-tree node size" ... "Error: The underlying task reported failure on exit".
Flash forward three days later: After unsuccessfully running Disk Warrior and Data Rescue for 20hrs (progress estimated it would take 400hrs to complete scan) - I gave up.
Sorry for the long setup, but my question is: can I just "zero" the drive and use it again, or is it "damaged" physically and suitable for a paperweight only. If it's usuable after reformatting, is there a way to test the hardware of the drive to assure it's stable?
Thanks for your time!

can I just "zero" the drive and use it again, or is it "damaged" physically and suitable for a paperweight only
Like Dwight I doubt the drive is physically damaged but simply has a damaged catalogue b-tree. The only way you're going to find out though it to erase the drive and write zeros to it. Just be aware that everything on the drive will be lost (though I gather you know that already) if you do this.

How do I fade in a roll over image

Hi,
I have a roll over text/png to link on my home page that I would like to fade in.
I saw something on the net and tried it and it didn't work.
Any thoughts? I realize these won't CSS work on all browsers. Should I go to Java?
My home page: www.adjacentdimensionsmedia.com
HTML:
<div class="clearovalfortree">
<a href="portfolio.html" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Image10','','images/treewithtextversion3.png',1)" class="opacity" >
<img src="clearovalfortree.png" alt="text for tree2" width="800" height="600" id="Image10"></a></div>
CSS:
img.opacity {
opacity: 0.5;
filter: alpha(opacity=50);
-webkit-transition: opacity 1s linear;
img.opacity:hover {
opacity: 1;
filter: alpha(opacity=100);
-webkit-transition: opacity 1s linear;
Paul

All you need to do is place the images on top of each other and change the opacity of the top image on hover as in
<!doctype html>
<html>

<meta charset="UTF-8">

Displaying the entire text of a tree node when the tree isn�t wide enough

Hi,
I have a JTree displayed in a JScrollPane, so there is a chance that some of the tree data may be hidden if the tree's width is insufficient, so when the user moves the cursor over a tree node whose text is not completely visible (cut off by the right edge of the scroll pane and/or window), a tooltip is displayed to show the entire node text. So far so good!
If the user double click a node in the tree a new window is supposed to be opened. This works fine if the tooltip hasn�t been displayed jet, but if it has then the user has to click 3 times to open the window.
The first time to remove the tooltip and the next 2 opens the window.
How can I awoid this?
Thanks!!!!
:-)Lisa

Any ideas, please?

WebDynpro ABAP tree node collapse trigger event of row selection

Hello expert,
I have a table in my WD abap view, I use MasterColumn to display the tree structure, everything works just fine.
However I encounter one problem:
If I open the tree structure and select one node (table row selection), the event onLeadSelectis triggered, this is correct. However if I collapse any parent nodes (along the tree path) of the selected node, WD puts the selection on the clicked parent and thus the event onLeadSelect is triggered for the parent. This is a strange behavior, because when I collapse a node, I certainly don't want to trigger the onLeadSelect event for the node, becaseu this would invoke the function linked to the event which is only supposed to be triggered when you explicitly select the table row. (BTW, if you don't select any child nodes, then collapse the parent, it does NOT trigger the event).
I've looked into the wdevent data to see if I can differentiate between the event of node collapsing and row selecting, event data is exact same for both cases, thus I have no way to stop the event handler in case of node collapsing.
Anyone had this issue and a solution for this?
Thanks
Jayson

Hi Jayson,
Its the behavior of the tree element, the lead selection of child is carried over to the parent.
Whenever there is lead selection set and on toggling of tree node, first OnToggle event triggers and then OnLeadSelect triggers. So you can control the execution of onLeadSelect by using EXPANDED parameter of event OnToggle.
Please refer the below steps:
Create an action ON_TOGGLE for the vent OnToggle of tree element and it will be having parameter EXPANDED
Create an attribute in view-->attributes tab GV_EXPANDED
Collect the parameter EXPANDED into gv_expanded
wd_this->gv_expanded = expanded.
Now, you can use wd_this->gv_expanded to control the execution of LEADSELECT logic
Hope this helps you.
Regards,
Rama

I try using this code but didn't work and not sure what syntax it went wrong.
rg_data := FIND_GROUP('RG_BANKNAME');
-- Add the new node at the top level and children.
--v_ignore := POPULATE_GROUP(rg_data);
Ftree.Add_Tree_Data(htree,
Ftree.ROOT_NODE,
Ftree.PARENT_OFFSET,
Ftree.LAST_CHILD,
Ftree.RECORD_GROUP,
rg_data);
The record group object Record Group Query the sql statement look like this :
SELECT NAME, SHORT_NAME FROM C_BANKS
Also you have any example using SIBLING_OFFSET and when to use it?
Thanks
David

The Recordgroup has to have a specific structure, maybe this helps http://andreas.weiden.orcl.over-blog.de/article-29307730.html

Hierarchical tree node problem

Hi all --
Today's problem is (drum roll)............
My application uses a heirarichal tree where each tree node contains the name of a form within this system. The user can navigate from form to form by clicking the appropriatetly name tree node. This seems to work - sometimes. Some users click on a node for one form, but get transferred to another named form(usually the one above or below the one actually activated). I've also found out that this happens ONLY when the user has their screen resolution set to 800 x 600. This application was developed at screen resolution 1024 x 768 and it woks fine. Anybody know why??

Here is the code for both the tree node selected and tree node activated triggers
Tree Node Seleceted code:
:CONTROL.Node_Activated := null ;
:CONTROL.Node_Selected := Ftree.Get_Tree_Node_Property('CONTROL_TREE.MENU', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE) ;
===========================================================
Tree Node Activated code:
Declare
LN$I Pls_integer ;
Begin
:CONTROL.Node_Selected := null;
:CONTROL.Node_Activated := Ftree.Get_Tree_Node_Property('CONTROL_TREE.MENU', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE) ;
If :CONTROL.Node_Activated IS NOT NULL Then
if :GLOBAL.curr_proc_id <> :control.node_activated or :control.node_activated
is null then
CALL_FORM(:CONTROL.Node_Activated);
else
Set_Alert_Property( 'AL_FORM_OPENED', ALERT_MESSAGE_TEXT,
:CONTROL.Node_Activated || ' is already opened. Please check your current or previously opened library.' );
LN$I := Show_Alert( 'AL_FORM_OPENED' ) ;
end if;
end if ;
end ;

JTreeTable problem editing tree node

Hi,
Iam using the swing JTreeTable component and facing a problem. Iam displaying hierarchical data in the JTreeTable. Now I would like to provide the facility to edit a tree node. I have a TreeSelectionListener registered on the tree and a TreeModelListener registered on the DefaultTreeModel. Wheneve, I start editing a node by double clicking it the valueChanged method is called but I do not see the new value the user types in this method. I have another method setValueAt which is where I can see the new value the user has entered.
I can set this new value to the treenode using
node.setUserObject(newValue);However, if I do this, the next time I try to edit the same node, the editor component is painted over the tree node thus displaying an empty textfield that occupies the entire cell.
How can I make the editor appear above the tree node with the contents loaded in it always.
Any help is appreciated.
cheers,
vidyut

You bind a mouselistener to the tree, so it has to be handled there.
When clicking once (method should be "mouseReleased" or something, treenodes name (toString) should be .setText("");

Tree node retrieving data for the 1st node only for 3 data blocks ?!

Hello alllll
i have 3 DATA BLOCKS MAster-Detail-Detail ; GL_TYPES -< GL_ACCOUNTS -< GL_COMPANIES

the node selected shows data for the first node only; Say Assets but if i selected any other node it doesn't return any data ?
could any boady pls explain to me why is that happening ?
The following code is:

GL_ACCOUNTS_PARENT on GL_ACCOUNTS has a where clause on it's property;
account_id in ( select distinct account_id_parent from gl_accounts ) on GL_ACCOUNTS_PARENT block i am displaying on 1 row:
1. the account_id ,
2. the account
3. name and account_type_name in a LOV
on the second block GL_ACCOUNTS depending on the GL_ACCOUNTS table also am displaying muti rows :
1. the account_id ,
2. the account
and a relation on form
GL_ACCOUNTS.TYPE_ID = GL_ACCOUNTS_PARENT.TYPE_ID AND
GL_ACCOUNTS.ACCOUNT_ID_PARENT = GL_ACCOUNTS_PARENT.ACCOUNT_IDon the third block GL_COMPANY_COA depending on the table GL_COMPANY_COA
am displaying the company_id & company_name in multi_rows
GL_COMPANY_COA.ACCOUNT_ID = GL_ACCOUNTS.ACCOUNT_ID
how the data will be looking in data blocksam using the following link -> Large trees - using partial tree population

setEditable(true);
this.getCellEditor().addCellEditorListener(new CellEditorListener(){
public void editingCanceled(ChangeEvent e){
CellEditor cellEditor =(CellEditor)e.getSource();
System.out.println("editing canceled:"+cellEditor.getCellEditorValue().toString());

Tree item when-tree-node-selected fires differently from 6i to 10g.

In forms 6i, when you keyboard navigate between tree nodes, the wtns trigger will fire. In 10g it does not. In 10g, it will fire if you press the tab key or mouse click on a node.
Anyone know if this was done on purpose?
I ran into this after finally trying my props.fmb in 10g. It works fine in 6i, but not in 10g
copy of my form is here:
http://www.tailboom.com/oracle.php
Forms [32 Bit] Version 6.0.8.18.3 (Production) cleint server
Forms [32 Bit] Version 10.1.2.0.2 (Production)
I wrote most of the tree handling code for oracle apps APPTREE. This is the code that most if not all tree's in apps uses to build standard tree. So I have a pretty good understanding of the forms tree item. And know the wtns fired for web forms 6i on every node like 6i client server. This is very strange IMO.
Thanks.

Oleg,
thanks for the reference. Although the bug you identify deals with when-tree-node-activated, it is possible they fixed the when-tree-node-selected issue at the same time. With my test tree, i can currently duplicate both issues. I tried to download the patch, but it is only available for linux and unix. No windows patch. I don't have my linux env up and running to where I can test yet. So I can not confirm.
