Hi,
Can anyone send a sample code for keeping check boxes for the last level nodes(leaves) of the tree?
very urgent. points are assured.

Srinivas

Hi check out this coding
DATA: lt_item_layout TYPE lvc_t_layi,
        ls_item_layout TYPE lvc_s_layi,
       v_alv type ref to cl_gui_alv_tree.
ls_item_layout-fieldname =v_alv->hierarchy_column_name.
LS_ITEM_LAYOUT-CLASS   = CL_GUI_COLUMN_TREE=>ITEM_CLASS_CHECKBOX.
LS_ITEM_LAYOUT-EDITABLE = 'X'.
APPEND ls_item_layout TO lt_item_layout.
try this and let me know the result.

Using checkboxes as tree nodes

Hi friends,
can I add checkboxes as tree nodes? if yes, how this can be done?
Thanks in advances.

Hi,
sorry, but this question is not really easy to parse ( I tried two times and gave up ), can you reword it. What is it that you want to synchronize with a tree selection ?

Adding a checkbox to Trees

Hi,
Anyone how to add a checkbox to every item in a tree? I
wanted to implement something that looks like what is found when
you install software and get that grey check meaning not all the of
the children items are not checked. I am not an expert with
ItemRenderers.

Write your own table model like
tm extends DefaultTableModel{
@Override
public Class getColumnClass(int index){
if(index== <your column for boolean>){
      return Boolean.class;
   }else
      return super.getColumnClass(index);
}

Menu option under recursive tree item/folder & checkbox in tree

Hi,
I want to present a checkbox next to an item or folder in a recursive tree.
I didn't see any option to do it so I tried to add a menu and a menu option type checkbox under the node item and note type.
The issue it does nothing.
Any ideas?
THanks,

Hi Akshay,
Everything mentioned here step by step:
0. You cannot use check-boxes inside tree, so you have to emulate them with images (or use Table with Tree-like master column -- not discussed in this message)
1. Create boolean attribute <b>isChecked</b> in node
2. Create calculated read-only string attribute cbIcon, write following in generated getter function:
return element.getIsChecked() ?
"~sapicons/b_okay.gif" : "~sapicons/b_canc.gif";
or whatever images you are using.
3. Create & bind action onAction for TreeNode / TreeItem.
-- apply parameters mapping in wdDoModifyView:
if ( firstTime )
final IWDTreeNodeType treeNode = (IWDTreeNodeType)
view.getElement("<your-tree-node-element-id>");
treeNode.mappingOfOnAction()
.addSourceMapping("path", "selectedElement");
<b>Your action must define parameter with type of your node element and name <i>selectedElement</i></b>
-- write the following code for handler:
selectedElement.setIsSelected( !selectedElement.getIsSelected() );
4. Bind cbIcon attribute as TreeNode / TreeItem image source, bind rest of attributes.
--Done.

Display Checkbox along Tree node and its child elements

Experts,
I want to display a checkbox in front of the Tree displayed in the view. This is used for me to select the child item value for my selection condition.
let say if the user selects the node, all the child elements will be used for search condition.
Otherwise, if the node is expanded, then the checkbox selected in the child element will be used for search condition...
Can u ppl suggest me how to design it, if possible can u share some sample code or procedure to customize the Tree as per the requirement...
thanx in advance,
James...

Checkbox on Tree Leaf

Hi
I have created a tree in Apex 4 and I am having difficulty in creating a checkbox alongside each leaf of the tree.
Once checked, i would like to navigate to a specific page with the leaf details.
Any ideas of how to implement this?
Thanks.

Hi vee,
Sorry to hijack this completed tread.
I was trying to inject a check-box instead of an image modifying (see below) the code snippet you have provided.
$('div.tree li a').before('<a href="#"><input type="checkbox" name="edit_link"/></a>');
$('div.tree li input[name="edit_link"]').click( function() {
node_id = $(this).parents('li:first').attr('id');
alert('Selected node: '+node_id)
});I could see the checkboxes appear however, can not check them. It seems a follow-on action is cancelling out the selection.
http://apex.oracle.com/pls/otn/f?p=20358:9
Sorry, I am a JQuery beginner so could not explore much on it. I really appreciate if you could give some direction on how to go about with a solution.
What I am really after is the ability to add checkboxes to all nodes so that users could do multiple selection, based on which another report region can be filtered.
Also in IE the JsTree is rendering slow. Does the built-in JsTree support ajax expansion on nodes?
I really like to implement JsTree my own if it gives me more flexibility, but I guess it will be a big learning curve to transport JSON via ajax for node expansion, etc... but would be wonderful if there is an example available.
I hope you or somebody else could help.

Display checkbox in TREE

Using an RS_TREE
And i'd like to display in one of these fields a checkbox.
does any one have an id ?
Maybe a symbols ?
An icon(no icon for check box)
any help welcome...

Stephan,
I checked the function modules which you had mentioned.
A word of caution first.
These are SAP internally released functions and it is not recommended that this be used in customer programs as SAP can change these functions without any prior notice and this might affect your program. More over this function will not be supported by SAP through OSS.
Maybe when you add a node using RS_TREE_NODE you can set the display attribute SEU_KIND to 'I' for ICON or 'S' for symbol and look for a checkbox ICON or symbol.
Sorry that I could not help much.

Vani

ALV Tree - how to put checkbox on the node level?

Hello everyone!
I have an AlvTree and I have special column named SEL. That column contains checkboxes. I want to put additional checkboxes at the node level, I need them to create select all option.
In other words I must somehow create something similar to do_sum option. DO_SUM works for numeric columns, the sum of all rows in current node appears at the top level. So I must do the same but checkbox.
Are there any ideas?

Problem with Jtree and a checkbox

Hello,
I have a problem with my tree implementation.
I create a tree and i want to add a checkbox in each node.
this is my code :
DefaultMutableTreeNode root;
root = new DefaultMutableTreeNode(new JCheckBox());
DefaultTreeModel model = new DefaultTreeModel(root);
_tree = new JTree(model);
eastpane.add(tree);
THe problem is that my checkbox doesn't appear. And a message appears
instead of my checkbox.
But my tree appears.
Can anyone help me .
Thanks

You can provide a cell renderer to the JTree to paint the checkBox.
The following code checks or unchecks the box with each click also:
_tree.setCellRenderer(new DefaultTreeCellRenderer()
private JCheckBox checkBox = null;
public Component getTreeCellRendererComponent(JTree tree,
                                                Object value,
                                                boolean selected,
                                                boolean expanded,
                                                boolean leaf,
                                                int row,
                                                boolean hasFocus)
    // Each node will be drawn as a check box
    if (checkBox == null)
      checkBox = new JCheckBox();
      checkBox .setBackground(tree.getBackground());
    DefaultMutableTreeNode node = (DefaultMutableTreeNode)value;
    checkBox.setText(node.getUserObject().toString());
    checkBox.setSelected(selected);
    return checkBox;
});

Using check Box in a Tree Region style

I want to display some data in a hierarchical manner and use a checkbox for the user to select the node for which he wants to see a report.
I need to fetch the node value where the user has ticked in the check box.
I went through the documentation but it does not mention about using a checkbox.
Can any one please let me know if we can use checkbox to tree nodes and to capture the user checked nodes do we have to make the VO based on an EO or even with a read only VO I can know which node the user has selected.

How to make checkbox to be pre-selected in ALV

Hi all!
I`m creating ALV report and I want to create checkbox in the first column of the row. So I have a field SEL(1) in my structure and I`ve made the fieldcat:
gs_fcat-col_pos = 5.
gs_fcat-coltext = 'Check'.
gs_fcat-fieldname = 'SEL'.
gs_fcat-tabname = 'GT_TREE9001'.
gs_fcat-outputlen = 10.
gs_fcat-checkbox = 'X'.
gs_fcat-edit = 'X'.
That works, checkbox is displayed.
But now I need to make all the checkboxes to be checked for the first start of my program.
I mean when user executes my report all the checkboxes must be checked by default.
I have tried to do following:
loop at gt_tree9001.
gs_tree9001-sel = 'X'.
modify gt_tree9001 from gs_tree9001.
endloop.
But it doesnt work, I now see checkbox and mark 'X' near but not the checked ckeckbox.
Any help appreciated!

Solved.
My final code:
data: lv_tree_size TYPE i,
            ls_layout_item TYPE lvc_s_laci,
            lt_layout_item TYPE lvc_t_laci,
            lv_ind TYPE LVC_INDEX.
      CLEAR ls_layout_item.
      ls_layout_item-fieldname = 'SEL'.
      ls_layout_item-class = cl_gui_column_tree=>item_class_checkbox.
      ls_layout_item-editable = 'X'.
      ls_layout_item-u_class = 'X'.
      ls_layout_item-u_editable = 'X'.
      ls_layout_item-u_chosen = 'X'.
      ls_layout_item-chosen = 'X'.
      append ls_layout_item to lt_layout_item.
call method g_tree9001->set_table_for_first_display
      EXPORTING
        i_save              = 'A'
        is_variant          = ls_variant
      CHANGING
        it_sort             = gt_sort9001
        it_outtab           = gt_tree9001
        it_fieldcatalog     = gt_treefcat9001.
DESCRIBE TABLE gt_tree9001 LINES lv_tree_size.
DO lv_tree_size TIMES.
        CALL METHOD G_TREE9001->CHANGE_LAYOUT
          EXPORTING
            I_OUTTAB_INDEX = sy-index
            IT_ITEM_LAYOUT = lt_layout_item                .
ENDDO.
The main trick is in u_class, u_editable, u_chosen. These params say that layout should be changed. Only this way it will work.
And some helpful links:
ALV tree get selected checkbox
Checkbox ALV Tree CL_GUI_ALV_TREE
ALV TREE-Checkbox
CL_GUI_ALV_TREE and Checkboxes
Report BCALV_TREE_ITEMLAYOUT is also very helpful.

Tree using APEX 2.2

Hi
I have created a tree using APEX 2.2 and the wizard provided. The select for my tree is:
select "NODE_PRIMARY_KEY" id,
"NODE_FOREIGN_KEY" pid,
CASE
WHEN NODE_PRIMARY_KEY = :P6_SELECTED_PK THEN
'<span style="color:white;background-color:#0000CD;">'|| NODE_LABEL||'</span>'
ELSE
NODE_LABEL
END AS NAME,
'f?p=&APP_ID.:6:&SESSION.::NO::P6_SELECTED_PK:'||"NODE_PRIMARY_KEY" link,
NULL a1,
null a2
from "ADFY"."RRD_TREE_HIERARCHY"
ORDER BY 1
The above also highlights the current selected node. With a small data set the tree worked fine. Now that I have 'proper' data the tree's performance is not acceptable. I think the problem is due to the tree refreshing itself each time a node is selected. Is there anything that I can implement to stop this or to improve the performance of the tree?
I have tried the 'Tree with AJAX' example but couldn't really get it to work.
Thanks
Paul

Hi PARS,
Try the below query, I tried to run your query in SQL command and got the same error. I corrected your query, now its running in SQL Command,
select case when connect_by_isleaf = 1 then 0
                                              when level = 1             then 1
                                           else                           -1end as status,
level,
      apex_item.checkbox(1,empno,'')||ename as title,
       NULL as icon,
       EMPNO as value,
       null as tooltip,
       NULL as link
from "EMP"
start with "MGR" is null
connect by prior "EMPNO" = "MGR"
order siblings by "ENAME"
Hope It will work...I too referred that link you shared for this. But I am not sure we can use checkbox in tree report. Because we don't have any option to change the column 'display as' like 'standard report column'. then only it will show like checkbox else it will show the code like '<input type="checkbox" name="f01" value="7839" />KING'.
Thanks
Lakshmi
