Accessing the parent element of a tree node !

Hi All,
Im building a tree application, in which the user has the option for creating a new node at any level he wants. But my problem is, If the user wants to create a node at the same level of the selected node, how do I retrieve the parent element? Can someone help me in this regard? Ive done the following
1)     Created a node TreeNode with the required attributes & the recursive node.
2)     When the user clicks on any node, I am able to retrieve the selected element through recursive traversal (i.e. the instance of TreeNodeElement, say elmt)
3)     I was able to retrieve the parent element through the function elmt.node().getParentElement(). But it returns an instance of IWDNodeElement, which does not have the recursive node. Ofcourse, I cannot typecast IWDNodeElement to TreeNodeElement.
Then How do I retrieve the TreeNodeElement instance of the parent element? Someone please help..!
Thanks in Advance,
Best Regards,
Nibu.

Hi Nibu,
you should type as follows
IPrivateRecursiveTree.ITreeNodeElement ele=(IPrivateRecursiveTree.ITreeNodeElement)selectedElement.node().getParentElement();
this way you will get the Parent element of the current node.

How can I access the selected element of a DropDownByIndex-box?

Hi,
I want to create a WebDynpro with two web services. I created the first request with the first web service and the results are displayed in a DropDownByIndex-Box. Now the user should choose one of the results and I would like to use this for the request with my second web service. How can I access the selected Element of a DropDownByIndexBox in the Code?
Thank you!!
Julia

Hi Julia,
when user select one element in drop down it automatically set lead selection of node binded to dropdown.
For example if you bind a dropdown to node myNode with value attribute myAttribute the lead selection of node myNode is set in the position of element choose from user.
So to take this chooised element use this code:
wdContext.currentMyNodeElement.getmyAttribute()

Spry MenuBar - IE6 - how to make that submenu is shown above the parent element

Hi you all,
I need the menubar to open the submenu above the parent element.
Here´s what I did:I inserted a spry menubar and the only css-change I did was the one shown below in red "botom: 2em;"
This works exactly as I need it to - in Safari, Firefox and Opera.
In IE6 however, the submenu is shown far below the parent element. Is there a solution?
Greetings from Germany
Alex
/* Submenus should appear below their parent (top: 0) with a higher z-index, but they are initially off the left side of the screen (-1000em) */
ul.MenuBarHorizontal ul
    margin: 0;
    padding: 0;
    list-style-type: none;
    font-size: 100%;
    z-index: 1020;
    cursor: default;
    width: 100px;
    position: absolute;
    left: -1000em;
    bottom: 2em;

thank you very much, Nancy!

Possibly. It's hard to tell without seeing your page, though.

The position of Spry Menu Bar submenus is controlledby the margin
property on submenu ul tags.
1. Locate the ul.MenuBarVertical ul or ul.MenuBarHorizontalul rule.
2. Change the margin: -5% 0 0 95%; default values to the desired
values.

Also, look through the CSS coments for IE hacks. Often these
workarounds for older browsers can be commented out or deleted.
Test before you delete anything permanently.

Master-details problem: How to access the parent EO/VO in child side?

Hello
Refer to the reply of posting
Re: How to insert new records in Master and detail Forms.
I have got the following questions
The approach for setting the master-details relationship works well, however, in this example,
I have overriden the create(AttributeList attributeList) method of VO2, so after calling
DCBindingContainer dcb = ADFUtils.getDCBindingContainer();
OperationBinding oper = dcb.getOperationBinding("CreateInsertVO2");
oper.execute();
, it will enter the create() method of VO2, at this point, i can only access the argument attributeList
which stored the key value that link up parent and child, however, how can i get the entire VO1
for accessing the value of all VO1's attribute?
Thanks

Neon wrote:
Do you mean that i have to create createRow and insertRow action in blinding layer?No. The createInsert operation does just that
Neon wrote:
Or call these function in the VO overridden create() method?No. You can't do that.
In conclusion, I don't understand why the accessor returns null. Maybe someone else can shed some light... ?:|
One last suggestion from me is to try getting the VO1 directly from the AM instead.
This should work - it is not a recommended practice through.
Use the following code:
VO1RowImpl vo1 = (VO1RowImpl)this.getVO1();
// ensure that the VO1 VL accessor is properly initialized
if (vo1 == null) {
vo1 = (VO1RowImpl)((YourApplicationModuleImpl)this.getApplicationModule()).getVO1().getCurrentRow();
}

How to access the parent class variable or object in java

Hi Gurus,
I encounter an issue when try to refer to parent class variable or object instance in java.
The issue is when the child class reside in different location from the parent class as shown below.
- ClassA and ClassB are reside in xxx.oracle.apps.inv.mo.server;
- Derived is reside in xxx.oracle.apps.inv.mo.server.test;
Let say ClassA and ClassB are the base / seeded class and can not be modified. How can i refer to the variable or object instance of ClassA and ClassB inside Derived class.
package xxx.oracle.apps.inv.mo.server;
public class ClassA {
    public int i=10;
package xxx.oracle.apps.inv.mo.server;
public class ClassB extends ClassA{
    int i=20;
package xxx.oracle.apps.inv.mo.server.test;
import xxx.oracle.apps.inv.mo.server.ClassA;
import xxx.oracle.apps.inv.mo.server.ClassB;
public class Derived extends ClassB {
    int i=30;
    public Derived() {
       System.out.println(this.i);                  // this will print 30
       System.out.println(((ClassB)this).i); // error, but this will print 20 if Derived class located in the same location as ClassB
       System.out.println(((ClassA)this).i); // error, but this will print 20 if Derived class located in the same location as ClassA
    public static void main(String[] args) {
        Derived d = new Derived();
Many thanks in advance,

Hi ,
You cannot access the controller attribute instead create an instance of the controller class and access the attribute in the set method
OR create a static method X in the controller class and store the value in that method. and you can access the attribute by
Call method class=>X
OR if the attribute is static you can access by classname=>attribute.

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!!!!

Hi Experts,
I am using drag and drop functionality in af:tree.In that i used one tree for drag source and another one tree for drop target,and it is working as expected.
Now I want to bring one additional option in the context menu of the target tree node that is ,when i right click on any of the target tree node in addition to the default menu options like "Collapse","Expand" i want to add one more option .For this i added "contextMenu" facet after the "nodeStamp" facet inside the tree.
*<f:facet name="contextMenu">*
*<af:popup id="p1">*
*<af:menu text="Delete" id="m1">*
*<af:commandMenuItem text="Delete" id="cmi1"*
*action="#{myWorkflow.deleteWorkflowNode}"/>*
*</af:menu>*

Now the problem is : before using drag and drop the context menu workes without any problem .But after using drag and drop the context menu is not popped up.

Hi
You need to do a recursion. If the reference you get from the array "controls[]" if of type cluster, then you have to loop through recursively.
Openg toolkit has variant tools that might be of some help to you (www.openg.org).
Good luck

I suggest posting this question on the LabVIEW forum. This is the Measurement Studio for Visual Basic forum and there are not nearly as many LabVIEW experts that monitor this forum as the LabVIEW forum.

What event is called when the handle next to a tree node is clicked

Hi,
I have a JTree...and the nodes in the tree have a little handle next to them. When i click on the handle, the children of that node, are shown below (as expected). However, what event occurs before the treeExpanded event is fired?? it seems like something happens just before it.
thanks

Post your code, I dont think any event except treeExpanded is fired.

How to add style(color) info for the color used in ALV tree nodes

I have an object for CL_GUI_ALV_TREE and I have added nodes to the tree and has set color for the nodes using 'STYLE' parameter. Now if I have to add the style info to the style(color) then how do I do it using the object I have?
Edited by: Sujay V Koparde on Feb 20, 2008 4:27 AM

Yes Eshwar, its similar to what you have written but my problem was that the style has already been assigned in the code and now I want to assign the style info(tooltip text) to the style(colour). I have an object of class cl_gui_alv_tree as of now and I am not able to find out as to how do I proceed to assign style information

How to get the children for a selected tree node?

Hi,
I want to get the number of child nodes for any selected node in JTree.
How can i do this?
Any help, greatly appreciated!!

if you have a node already where aNode is a DefaultMutableTreeNode for example, then you can use that object's API method to get the child count.
int childCount = aNode.getChildCount();
If you want to loop through all of a node's children and do something at each node, the following may help:
java.util.Enumeration e = aNode.children();
while ( e.hasMoreElements() ) {
DefaultMutableTreeNode n = (DefaultMutableTreeNode)e.nextElement();
//Do something with n
Hope this helps,
Claire
