Checkbox Trees

Hi All,
I have a requirement that I feel would be best implemented with a tree if I can get the functionality working.
First off I am on apex 4.2.2.00.11. I implemented a solution for creating a checkbox tree that Alex Nuijten https://plus.google.com/118115428098299370580 discussed in his blog from 7/23/2013. I then added in the drag and drop functionality that was discussed in forum thread https://forums.oracle.com/thread/2274874.
Now I have a tree that has the chechboxes and the ability to reparent a node through drag and drop. The problem I now have is in trying to save the changes and acting upon the checked nodes. When I check a node I would like to perform an action in the database. Unfortunately I am drawing a blank on how to reference the nodes.
Just wondering if anyone might have any ideas on how to do this?
Thanks for your time.
Tom

A checkbox tree control

Hi All,
I need to create a checkbox tree control to show the user and make him select the directory listing of application-home on the server side. I have a solution wherein I have to submit the page every time the checkbox is clicked, but that is not efficient.
I need to select all the child node checkboxes once the parent checkbox is selected and well I need to show the parent checkbox greyed if even one child is not selected and show the parent deselected if all child nodes are unclicked.
Please Help...
Thanks
Ultimate.

U can handle all these by JavaScript. there's no time to sit and write code fer u, just try to show the way!
do some search on huge set of javascript codes/sample on net to handle those things.

3 State CheckBox Tree

I just downloaded the 3 State CheckBox Tree custom control
from the Flex dev exchange a few moments ago. I put the code into a
Flex prject, compiled it and ran it pretty much unchanged. When I
click on any of the tree controls I get the error message:
ArgumentError: Error #2025: The supplied DisplayObject must
be a child of the caller.
at flash.display::DisplayObjectContainer/getChildIndex()
at mx.managers::SystemManager/getChildIndex()
at mx.managers::SystemManager/::mouseDownHandler()
Anybody else download this tag and have a problem like
this???

O.K. I pulled the downloaded component inside an existing
application and ran it from there. The problem was that the
downloaded component had a <mx:Application...> tag in it
which gave me two templates with the <mx:Application ...>
tag. Flex didn't like this too much. After I renamed the
<mx:Application...> tag in the downloaded component to
<mx:Canvas...> life was good. One of those duh moments...
DUH!!! :)

APEX 4 checkbox tree template

Hello,
why is no more available the checkbox tree template?
is there a workaround to obtain the same result starting from the classic template?
Thank you,
matteo

Oracle - can we not at least have what you had working for check boxes so we can try to extend it to our needs.????
We have a great need for the ability to show what was checked, we can use AJAX to do whatever process...
Any help is much appreciated... :>)
Thanks, Bill

Checkbox Tree

In old threads about new tree functionality in 4.0 I see examples of the Checkbox Tree, however, in the final version when I create the tree I do not see this option. Was it dropped from final release or am I doing something wrong?

Hi All,
I just came across this code that searching the forum for "tree", one of the first posts.
It is not showing correctly below so go to this link and look at original:
Tree Formatting
It allows the HTML tags to be interpretted as HTML tags...
/* getElementsByClass from http://bit.ly/dj8Xk8 */
function getElementsByClass( searchClass, domNode, tagName) {
     if (domNode == null) domNode = document;
     if (tagName == null) tagName = '*';
     var el = new Array();
     var tags = domNode.getElementsByTagName(tagName);
     var tcl = " "+searchClass+" ";
     for(i=0,j=0; i<tags.length; i++) {
          var test = " " + tags.className + " ";
          if (test.indexOf(tcl) != -1)
               el[j++] = tags[i];
     return el;
function fixTreeHTML() {
     var treeParts = new Array("leaf","open","closed");
     for( p=0; p < treeParts.length; p++ ) {
          var nodes = getElementsByClass(treeParts[p],document,'li');
          for( i=0; i < nodes.length; i++ ) {
               var ihtm = nodes[i].innerHTML;
               ihtm = ihtm.replace(/& lt;/ig,"<"); // there is a space & lt just to post on forum

Checkbox Tree in JavaFX

Does anybody has an idea where I find an example for a checkbox Tree? Thx

There is no Checkbox Tree control in JavaFX (as of now). I've written one long time back in Java. You could adopt it to use in JavaFX as a swing component.

CheckBox Tree Component

Hye guys,
I need a custom tree component for some xml elements that represent some files and their attributes. I have written one such component but what I need now to add to this component is Checkboxes.
The user is supposed to select files from this Tree component via these chk boxes.
Can someone point me in the direction of such an existing Tree component.
Or if I have to write one how do I go about it.
Pls donot point me to the Java tutorial. I read it but I still have a very very vague idea, if any idea at all, of doing this.
Regards

Can't get Checkbox selection status in Tree

Hi,
I'm using a Checkbox Tree which I got from here: [http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm|http://www.java2s.com/Code/Java/Swing-JFC/CheckBoxNodeTreeSample.htm]
Now, I want to determine whether the Checkboxes are selected or not.
Unfortunately, the custom CheckBox model class always returns true, which is stored in a Vector.
In short, this is how the checkTree is created:
CheckBoxNode tabFormatNode = new CheckBoxNode[]{new CheckBoxNode("GP3", true),
                                    new CheckBoxNode("GP4", true),
                                    new CheckBoxNode("GP5", true)};
NamedVector formatVector = new NamedVector("Format", tabFormatNode);
Object[] rootNodes = new Object[]{ formatVector }
Vector rootVector = new NamedVector("root", rootNodes);
TreeModel model = createTreeModel(rootVector);
setModel(model);As I said, when I retrieve a CheckBoxNode from the Vector, it always return true on isSelected(), so that's no use.
However, the renderer does manage to get the selection status correctly.
private static class CheckBoxNodeRenderer implements TreeCellRenderer
        private JCheckBox leafRenderer = new JCheckBox();
        protected JCheckBox getLeafRenderer()
            return leafRenderer;
        public CheckBoxNodeRenderer()
        public Component getTreeCellRendererComponent(JTree tree, Object value,
              boolean selected, boolean expanded, boolean leaf, int row,
              boolean hasFocus)
            Component returnValue;
            if (leaf)
                String stringValue = tree.convertValueToText(value, selected,
                    expanded, leaf, row, false);
                leafRenderer.setText(stringValue);
                leafRenderer.setSelected(false);
                if (selected)
                    leafRenderer.setForeground(selectionForeground);
                    leafRenderer.setBackground(selectionBackground);
                else
                    leafRenderer.setForeground(textForeground);
                    leafRenderer.setBackground(textBackground);
                if ((value != null) && (value instanceof DefaultMutableTreeNode))
                    Object userObject = ((DefaultMutableTreeNode) value)
                    .getUserObject();
                    if (userObject instanceof CheckBoxNode)
                        CheckBoxNode node = (CheckBoxNode) userObject;
                        leafRenderer.setText(node.getText());
                        leafRenderer.setSelected(node.isSelected());
                        // eigen
                        leafRenderer.setEnabled(Overview.getTabbedPane().getActiveTabList().isLeftPaneEnabled());
                returnValue = leafRenderer;
            else
              returnValue = nonLeafRenderer.getTreeCellRendererComponent(tree,
                  value, selected, expanded, leaf, row, hasFocus);
            return returnValue;
    }Could anyone help me with retrieving the correct selection values of the CheckBoxes?
Edited by: Tails on 21-mrt-2008 13:07

OK Tails. here are the changes you need, in CheckBoxNodeEditor method getTreeCellEditorComponent. Note that Component editor is now declared as final so that in can be accessed from within the inner class.   public Component getTreeCellEditorComponent (JTree tree, Object value,
         boolean selected, boolean expanded, boolean leaf, int row) {
      // change to final
      final Component editor = renderer.getTreeCellRendererComponent (tree, value,
            true, expanded, leaf, row, true);
      // editor always selected / focused
      // line added
      final CheckBoxNode cbn = (CheckBoxNode) ((DefaultMutableTreeNode) value).getUserObject ();
      ItemListener itemListener = new ItemListener () {
         public void itemStateChanged (ItemEvent itemEvent) {
            // line added
            cbn.setSelected (((CheckBoxNode) getCellEditorValue ()).isSelected ());
            if (stopCellEditing ()) {
               fireEditingStopped ();
      if (editor instanceof JCheckBox) {
         ((JCheckBox) editor).addItemListener (itemListener);
      return editor;
   }Get back to us on whether that solves the problem, willya.

[APEX 4.0] EA2 Tree , checkbox

I'm checking out the new APEX tree region, to be exact the checkbox tree. But how can you read values from this tree. It's values are not stored in the session it seems.

Hello Harvey,
It is the jsTree ([http://www.jstree.com/]) jQuery plugin. You should be able to use that already in the current version of APEX.
If it will be an APEX Plugin in the near future? I guess that's more up to you (or "us", as APEX Developers) to create a nice Plugin for it.
But maybe the APEX Dev Team will create one as example if you're nice to Patrick or Anthony ;-)

Selected Tree Checkboxes Value

Hi,
can someone assist me on this?
I have a Checkbox Tree and I would like to show in a page item (for example a Text Area) the value of all selected checkboxes.
My page item name is P6_FEEDBACK and should be in the same page as my Tree region (name of Tree region is Treeviw1).
This is my Tree Query:
SELECT
CASE
    WHEN connect_by_isleaf = 1
    THEN 0
    WHEN level = 1
    THEN 1
    ELSE -1
END AS status,
LEVEL,
OBJECT_NAME AS title,
NULL        AS ICON,
OBJECT_NAME AS value,
OBJECT_NAME AS tooltip,
null as link
FROM
OWNER.TABLE_NAME
WHERE
    PARENT_OBJ_1 = v('TABLE')
OR OBJECT_NAME = v('TABLE')
OR PARENT_OBJ_2 = v('TABLE')
START WITH PARENT_OBJ_2    is null
CONNECT BY prior OB_P1= P1_P2
ORDER SIBLINGS BY
OBJECT_TYPE,OBJECT_NAME;
I also tried to modify the above query and add a limk to the page item but this is not working.
Thanks

Hi ,
Thank you that was exactly what I was looking for. I couldn't find how to pass database column to javascript as an input parameter. So thanks for your help. I made a couple of correction :
1) I put additional ' characters to ('''||"NAME"||''') this part because my field is varchar.
select case when connect_by_isleaf = 1 then 0
when level = 1 then 1
else -1
end as status,
level,
NAME as title,
null as icon,
"ID" as value,
null as tooltip,
'javascript:setFObjName('''||"NAME"||''')' As link
from "#OWNER#"."TABLE_NAME"
start with "PID" is null
connect by prior "ID" = "PID"
2) In script I have added ' character before and after page item.
function setFObjName(pobjName){
$s('P1_OBJ_NAME', pobjName);
So it works. Thanks tfor your help.

FileSystemTree and TreeItemRenderer random selected Checkboxes

When implementing
Three
State Checkbox Tree solution on a FileSystemTree, the
checkboxes will randomly change states while scrolling. This
happens when the checkbox leaves the viewable area.
The state of the check box is being held within a
ModelLocator from the Cairngorm project (obviously using the
framework). Is there any work around for this? I have changed very
little of the code given in the cookbook example. Of course I am
passing in the FileSystem.File object and checking the nativePath
against the data inside the ModelLocator. There is a hash map
implementation storing the state.
Any help would be most welcome. I think I am far more bald
now then when I started coding this.
- Blake

Hi Blake,
I have been looking at it for the past couple of days.
Couldn't figure it out yet.. With the FileSystemTree the File
object is being passed in. How do you store state in it? Tried
hacking by storing it in File properties like url but doesn't work.
You mention about a "hash map implementation storing the state".
Any info about it would be great.
Thanks.

Between when you posted the question and the entire 50 minutes you waited for an answer, I tried compiling that code you posted, with a view to help out.
What I found was..
That code did not compile as posted.
- It was missing imports
- There was a direct reference to setLayout that applied to no member
- model was not declared properly
It also shows unchecked add warnings, please fix those before posting.
BTW - please do not remove indenting from posted code, it makes it very hard to read, replace any tabs in the source for 2-4 spaces instead. Also, code is easier to examine when it is enclosed in 'code' tags - this can be achieved by selecting the code and pressing the 'code' button above the form field we type the messages.
On the subject of what you are trying to do, please trim your example down to something that tries to create this tree form any directory structure the user might specify with a JFileChooser, because I am running a slow machine with large drives, and creating a JTree of the entire file system would take far too long.
Fix those things, and I'll take a second look.
As an aside. If you wish to get answers 'within the hour', you will probably need a consultant or a help desk. If you post to these forums, you need to be more patient.

How to use frame in struts

Hi all,
I am using Struts framework.
I have two part in a jsp page, in which i am getting data from previous page by using request.getParameterValues("date");
i.e i am getting multiple date.
Now in first part of jsp page i have checkbox tree ,where user can select checkbox, then click on submit .Now on click submit data will pass second part of jsp page.where with checked data
and date i have to do some process.
it is like frame type structure, where data from one frame will pass in second frame in jsp page.
I request to all JGuru to guide me how to do it.
Deepak

Just let it access the request parameters the same way? Using HttpServletRequest#getParameter() and so on.

fieldcat are several fields all as checkbox.
Then i get a component of the output structure and set a X.
ASSIGN COMPONENT lv_help_arbpl OF STRUCTURE <go_data_struc>

            node_not_found       = 2
            OTHERS               = 3.
in <go_data_struc> the fields which should be set, are set with X.
But after i add all of my nodes and do CALL METHOD p_go_alv_tree->frontend_update, the checkbox is empty but there is an X in the field beside the checkbox.
Thanks in advance.
