ABAP WD: Fully expand a Tree

Hi all,
I'm having a very hard time achieving the following:
I would like to FULLY EXPAND a WD tree in code.
Allthough it sounds easy i dont get it to work.
What have i tried allready:
- the 'Expanded' property of the treenode at designtime.
- if_wd_context_node->SET_LEAD_SELECTION
- if_wd_context_element->set_selected
- fiddled with the 'Initialisation Lead Selection' property
Any suggetsions?
Thanks alot!
Joris Bots

Roberto,
Thanks for the quick help.
I dont have a recursive node, since my tree is allways 2 levels deep, so i have a tree with 1 TreeNodeType and 1 TreeElementType.
What i dont get to work is to get a reference to the (instantiated) nodes at runtime.
all i get is a Table with the nodeTYPES (the metadata of the Tree)
Please have a look at this:
my tree in RUNTIME looks like this
Root
 N1
 item1
 item2
 item3
 N2
 item1
 item2
 item3
 N2
 item1
 item2
 item3
my tree in designtime looks like this
MY_TREE
 NodeType1
 ElementType1
what you are saying is that i need to set the EXPANDED property of N1, N2 and N3 at runtime instead of setting the property of NodeType1 designtime, right?
I dont know how to get the Ref's to the N1..3 object.
Hope you can help me,
Thanks

Hi every body,
I have represented into jtree form after reading xml document using the tree model. But I want to displayed

Thanks for your help
For get the the tree in expanded form, I am using the expandAPath funtion by the following way.
public class XMLTreePanel extends JPanel {
 private JTree tree;
 private XMLTreeModel model;
 public XMLTreePanel() {
 setLayout(new BorderLayout());
 model = new XMLTreeModel();
 tree = new JTree();
 tree.setModel(model);
 tree.setShowsRootHandles(true);
 tree.setEditable(false);
 expandAPath(tree);
 JScrollPane pane = new JScrollPane(tree);
 pane.setPreferredSize(new Dimension(300,400));
 add(pane, "Center");
 final JTextField text = new JTextField();
 text.setEditable(false);
 add(text, "South");
 tree.addTreeSelectionListener(new TreeSelectionListener() {
 public void valueChanged(TreeSelectionEvent e) {
 Object lpc = e.getPath().getLastPathComponent();
 if (lpc instanceof XMLTreeNode) {
 text.setText( ((XMLTreeNode)lpc).getText() );
public void expandAPath(JTree tree){
 for(int i=1; i<tree.getRowCount(); ++i) {
 tree.expandRow(i);
public void setDocument(Document document) {
 model.setDocument(document);
public Document getDocument() {
 return model.getDocument();
}

Box model experts, why wouldnt this layout allow for a container div to fully expand?

You have an answer for the height issue, you may also be interested in this article that talks about cutting down on the stylesheet size... you have a lot of styles in your stylesheet that can really be trimmed down by using shorthand rules.

How do I make my dataGrid fully expand?

I am trying to make my dataGid fully expand. I mean I don't
want to see scroll. If it has 5 rows, then its height will be
exactly fit 5 rows. If it has 10 rows, then its height will be
exactly fit 10 rows.
How do I do that?
Thanks.

Hello,
Use the ftree package's functions
code to expand all nodes:
PROCEDURE explose_tree IS
node    ftree.node;
htree   ITEM;
state   varchar2(30);
BEGIN
   -- search the tree ID --
   htree := Find_Item('BL_TREE.TREE_1');
    -- search the root --
     node := Ftree.Find_Tree_Node(htree, '');
    -- expand all nodes --
   WHILE NOT Ftree.ID_NULL(node) LOOP
      state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
      IF state = Ftree.COLLAPSED_NODE THEN
        Ftree.Set_Tree_Node_Property(htree, node, Ftree.NODE_STATE, Ftree.EXPANDED_NODE);
      END IF;
      node := Ftree.Find_Tree_Node(htree, '', ftree.find_NEXT,Ftree.NODE_LABEL,'', node);
   END LOOP;
END;and to collapse all nodes:
PROCEDURE Implose_tree IS
   node   ftree.node;
   htree ITEM;
   state varchar2(30);
BEGIN
   -- search the root ID --
   htree := Find_Item('BL_TREE.TREE_1');
   -- search the root --
   node := Ftree.Find_Tree_Node(htree, '');
   -- Collapse all nodes --
   WHILE NOT ftree.ID_NULL(node) LOOP
     state := Ftree.Get_Tree_Node_Property(htree, node, Ftree.NODE_STATE);
     IF state = Ftree.EXPANDED_NODE THEN
      Ftree.Set_Tree_Node_Property(htree, node, Ftree.NODE_STATE, Ftree.COLLAPSED_NODE);
     END IF;
    node := Ftree.Find_Tree_Node(htree, '', Ftree.FIND_NEXT,Ftree.NODE_LABEL, '', node);
   END LOOP;

Why when I fully expand the screen contents do I lose the red,yellow,and green options at the top left

why when i fully expand my screen contents do i lose the red, yellow, and green buttons at the top left used to close, expand, and minimize

That's just the way it is in full screen mode. You need to come out of FS to see the dots again.

Expand the tree like I want

A JTree like this:
0:model
0.1:jsp1
0.2:jsp2
I want to add jsp1's child node-jspchild1,so the tree will turn into:
0:model
0.1:jsp1
0.1.1:jspchild1
0.2:jsp2
But when I finished adding,the jsp1 is collapsed,how can I expand the tree to the level of my new node?Thank you.

tree.expandPath(new TreePath(((DefaultMutableTreeNode)jspchild1.getParent()).getPath()));Denis

How to expand a tree at a specific node/item?

Hi,
we have a tree and the nodes/items were binded to context with this code
lo_nd_nvccmp = wd_context->get_child_node( name = wd_this->wdctx_nvccmp ).
lo_nd_tree = lo_nd_nvccmp->get_child_node( name = wd_this->wdctx_tree ).
lo_el_tree = lo_nd_tree->bind_structure( new_item = ls_tree set_initial_elements = abap_false ).
We want that the tree is expanded at a specific node/item?
The structure has the field is_expanded of type WDY_BOOLEAN. I think that if the field of the right structure is 'X' then the tree should expanded. How can we find the right structure in the context and change this field to 'X'?
Code is appreciated.
Thanks, regards
Susanne

Oh, apparently if you try that call right after you create
the Tree, it will throw a null reference exception. That might
count as a bug in the flex api...
If you create a Tree, and give it's dataProvider some xml
data, and then add it to the stage (addChild), and then you call
expandItem or expandChildrenOf() right after, you will get a null
object exception. You have to wait... for something. I don't know
what.
I even tried calling _tree.invalidateList() before the
expandItem, but it will still throw the error...
I wonder what the Tree needs to wait for? Is this a bug for
Adobe to fix?

Expand the tree by default

Hi,
I have a tree component in my Application and I have given the dataprovider as XMLListCollection. I would like to have the entire tree as expanded mode(all children) by default. To achieve this, I tried expandItem() method but I couldn't see the entire tree as expanded when I load my application.
Any solution will be helpful for me a lot!
Thanks in Advance,
Srinivasan S

A more elegant solution ( in my opinion ) would be to extend the Tree component and implement the desired behavior in a much nicer fashion. It is true that we already have expandChildrenOf(); method that is really great, but if we want to have a nice feature that instantaneously expands or collapses the whole tree more easily ( without having to rewrite the same conditions and who knows what each time we want such a functionality ) then I think that it would be much nicer to extend the Tree component, add the desired feature and start using that custom component instead.
Here's a fast example ( make sure to place this class into a "components" folder if you want to test it ):
package components
 import mx.controls.Tree;
 * Custom <code>Tree</code> class with custom behavior.
 public class ExpandableTree extends Tree
 * Flag telling if the tree is expanded or not.
 protected var _isExpanded:Boolean = false;
 * Constructor.
 public function ExpandableTree()
 super();
 * Used to expand or collapse the <code>Tree</code>.
 * @param value Flag telling if we should expand or collapse the <code>Tree</code>.
 protected function expandCollapseTree(value:Boolean):void
 // Return if there's no data to expand or collapse.
 if (this.dataProvider == null)
 // The flag should be "false" if no expanding has occurred.
 _isExpanded = false;
 return;
 // Expand or collapse the children.
 this.expandChildrenOf(this.dataProvider[0], value);
 // Overridden methods
 * @inheritDoc
 override protected function updateDisplayList(w:Number, h:Number):void
 // Expand or collapse the Tree.
 expandCollapseTree(_isExpanded);
 super.updateDisplayList(w, h);
 // Setters and getters
 * Set a flag telling if the <code>Tree</code> should be expanded or callapsed.
 public function set expanded(value:Boolean):void
 // Make sure that the passed value is not the current state.
 if (value == _isExpanded) return;
 _isExpanded = value;
 // Invalidate the display list to signal the change.
 this.invalidateDisplayList();
 * Returns the current state of the <code>Tree</code>.
 public function get expanded():Boolean
 return _isExpanded;
Obviously, you can always extend this "skeleton component" and add even more features. Also, there's another fast example to demonstrate the usage of the component I've just posted above ( it's really simple ):
<?xml version="1.0" encoding="utf-8"?>
<mx:Application
 xmlns:mx = "http://www.adobe.com/2006/mxml"
 xmlns:components = "components.*"
 backgroundColor = "0xFFFFFF"
 backgroundGradientColors = "[0xFFFFFF, 0xFFFFFF]"
 layout = "vertical">
 <mx:XMLList id="treeData">
 <node label="Mail Box">
 <node label="Inbox">
 <node label="Marketing"/>
 <node label="Product Management"/>
 <node label="Personal"/>
 </node>
 <node label="Outbox">
 <node label="Professional"/>
 <node label="Personal"/>
 <node label="Outbox">
 <node label="Professional"/>
 <node label="Personal"/>
 </node>
 </node>
 <node label="Spam"/>
 <node label="Sent"/>
 </node>
 </mx:XMLList>
 <components:ExpandableTree
 id = "cmpExpandableTree"
 width = "400"
 height = "300"
 showRoot = "false"
 expanded = "true"
 labelField = "@label"
 dataProvider = "{treeData}"/>
 <mx:HBox width="400">
 <mx:Button
 label = "Collapse"
 width = "100%"
 click = "cmpExpandableTree.expanded = false;"/>
 <mx:Button
 label = "Expand"
 width = "100%"
 click = "cmpExpandableTree.expanded = true;"/>
 </mx:HBox>
</mx:Application>
So, this would be the "neater solution" ( in my opinion ). But simply using expandChildrenOf(); and passing in the item from where you want to rest of the nodes to expand is just as valid.
With kind regards,
Barna Biro

WD ABAP: Need beginner help on TREE UI ELEMENT

Hi all,
I'm struggling with the Tree element in Webdynpro (ABAP!).
Can anyone provide me with a help/tutorial/examplecode on how to correctly bind a tree to context, and how to fill the context
I have an IT with a field (int) that descibes on what level the item has to go into the Tree.
i hope i can use this to populate the context
example IT:
0 my cars
1 trucks
2 red Dodge
2 blue RangeRover
1 sportscars
2 red ferrai
2 blue porsche

WD ABAP: Recursion Nodes that Repeat Tree Nodes with Embedded Tables ???

At Rich H's suggestion, I'm posting this here as well as in the blogs.
Suppose you've got a tree context with a node that has a table embedded under it. (For example, the TREE_WITH_TABLE view of WDR_TEST_EVNT has this kind of context substructure.) Call this node "NODE_WITH_TABLE."
You now define a recursion node underneath "NODE_WITH_TABLE" and specify "NODE_WITH_TABLE" as the repeated node for this recursion node. Call this recurion node "RECURSION_NODE".
Lo and behold - the table fills properly when you're on any instance of "NODE_WITH_TABLE", but not when you're on an instance of "RECURSION_NODE".
I'm hoping that:
a) I'm doing something wrong;
OR
b) There's an easy work-around/alternative I'm not seeing
OR
c) SAP will give recursion nodes enough memory to carry any table(s) embedded in the nodes they're repeating.
'Cause I sure don't want to have to define "n" levels of tree-nodes that have different copies of the same table(s) embedded in them.

Maybe you might want to back out your weblog as it is not really a place to ask these types of questions. Think of it this way, if you are allowed to do this type of weblog, what is stopping any other weblogger. Hence the weblogs would just be another forum, which I don't think anyone wants.

Expand/Contract Tree Issue

Hi all,
I have a tree, which is a collection of all the pages in my application. I am using 2 level tabs as well. I want my tree to expand only that node page which is currently being clicked from the tab i.e when i click the tab in two level tabs, the page with the current node should open and rest all gets collapsed. Pls help.
With Regards,
Sunil Bhatia

Hi all,
Strange that noone has replied to this forum, anyways can anyone just let me know, is it possible or impossible to do this?
I just want that when a tab gets clicked, then there should be 2 request set in my code i.e CONTRACT, CONTRACT_ALL and EXPAND, TAB_NAME which will open my tree. These are working fine individually, but when i try to set 2 requests simultaneously, it doesnt renders. Pls do help me.
Thanks,
