Call a form by click a tree node

Hi,
How can I created tree and i wanna call form when tree node selected
Thank you
MNH

Hi ,
Use the "WHEN-TREE-NODE-ACTIVATED" Trigger , and you can retrive the selected node using :
- FTREE.GET_TREE_SELECTION.
- FTREE.GET_TREE_NODE_PROPERTY.

Clicking a tree node does not refresh the fields in the table component

hi all,
I am using a tree component along with a table component in my page.so whenever i am clicking on a node it should display the relevant information of that node in the table from the database.But whenever i am doing the page is not refreshing and the old values of the textfields in the table still exist.i have written the code to populate the table in a button click event.It is working fine but the same is not working when i am clicking any node in the tree component.Can anyone provide a solution to this problem.
Thanks and regards,
Prasant Kumar

Never mind... I actually found something that works...
treeModel.nodeStructureChanged(leadSelection);

Confirmation Dialog when clicking on Tree Node.

I am working on Oracle Apex 4.2.0.00.27 and I have the following problem:
The code below shows the definition of a tree. The tree displays records from the table ACTIVITIES in hierarchical structure.
When user clicks on a leaf/node of the tree he will be redirected to another page where the details of each Activity/leaf/node are displayed.
The tree is part of a page where I have established a functionality to check for changes on the input fields of the page and inform the user when he tries to redirect without first saving the changes he made.
What I want to do is:
WHEN user clicks on a node of the tree AND he hasn't saved any changes he made
THEN
trigger a confirmation dialog.
IF
he clicks OK he is redirected to the node details page as defined on the tree definition:
f?p=&APP_ID.:10:'||:APP_SESSION||'::::P10_ID:'||"ID"
ELSE if he clicks CANCEL
he stays on the same page.
The condition to trigger the confirmation box is:
if (document.getElementById('P0_CHANGES_DETECTED').value == 1)
where P0_CHANGES_DETECTED is a universal hidden text field that is set to +'1'+ every time a change is made.
and here is the tree definition:
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,
decode(PARENT_ID,null,null, 'f?p=&APP_ID.:10:'||:APP_SESSION||'::::P10_ID:'||"ID") as link
from "#OWNER#"."ACTIVITIES"
where GROUP_ID = :P20_GROUP_ID
start with "ID" in (select ID from "#OWNER#"."ACTIVITIES" where GROUP_ID = :P20_GROUP_ID and PARENT_ID is null)
connect by prior "ID" = "PARENT_ID"
order siblings by "ID"
I hope it is clear what I want to achieve. Thanks in advance.

So you'll want to bind an event to all tree nodes that checks for the value and then fires the confirmation if there value is 1.
Try something like this:
- first, give your static ID attribute in your tree the value of tree_static_id (or whatever you want. just replace the id selector below with what you choose).
- In your Page Function and Variable Declaration Javascript:
function confirmSave() {
var changeDetected = jQuery('#P0_CHANGES_DETECTED').val();
if(changeDetected == 1) {
//only do this if change is detected
if(confirm('You have unsaved changes. Do you want to leave this page?')) {
window.location('[your url here]');
jQuery(document).ready(function() {
//bind function to the click event
$('#tree_static_id').find('li a').bind('click', function() { confirmSave(); } });
});Hope this helps

How to programmatically click a tree node(make it selected)?

in my program, i want to make a tree node "clicked" by codes, so that the valueChanged(TreeSelectionEvent tse e) method of the TreeSelectionListener can be invoked.
thanks a lot!!

    private Robot robot;
    private void triggerMouseClick(TreePath treePath) {
        if (robot == null) {
            try {
                robot = new Robot();
                robot.setAutoDelay(60);
            catch (AWTException e) {
                e.printStackTrace();
        Rectangle rect = this.getPathBounds(treePath);
        Point point = new Point(rect.x+1, rect.y+1);
        SwingUtilities.convertPointToScreen(point, this);
        robot.mouseMove(point.x, point.y);
        robot.mousePress(InputEvent.BUTTON1_MASK);
        robot.mouseRelease(InputEvent.BUTTON1_MASK);
    }

Double-click on tree nodes

Is there a way to disable the double-click-to-expand-
node feature? This seems to be a default behaviour,
wish to remove it. Thanks in advance.

I use forms6i patch 12. And that is what I have:
Block 'TREE'
Triggers
WHEN-MOUSE-DOUBLECLICK
begin
:global.MDC := 1;
Message ('1', Acknowledge);
Pause;
end;
Tree_Item
WHEN-TREE-NODE-EXPANDED
begin
Message ('2', Acknowledge);
Pause;
if :global.MDC = 1 then
:global.MDC := 0;
Return;
else
FillLevel; --(e.g. fill the lower nodes and
-- expand the parent node)
end if;
end;
And that is what I get at runtime after double clicking on a collapsed node:
1 (acknowledge)
2 (acknowledge)
So WHEN-MOUSE-DOUBLECLICK fires prior to WHEN-TREE-NODE-EXPANDED in my environment.

How to go to different screen by Double Clicking a Tree Node

Hi guys,
I have a tool where i have a top panel and a bottompanel. On the top panel, i add Tab buttons so that if anyone is clicked, it will repaint the bottom panel with corresponding Tab screen(New screen will come with the top panel remaining same). There are Actions, Conditions,Trees tabs on the main panel. There is also a Home Tab on the main panel which when clicked brings up a tree structure on the left hand side of the bottom panel which has some parent and child nodes depending on whether they are files or directories. There are folders(parent nodes) with names Trees & Conditions also related to the Tabs on the main panel under which i have some file names. I am including the method which creates the nodes. The problem is that when i double click any file(not a directory), it should take me to the screen which is actually populated when i select the Trees/Conditions tab and select the corresponding file name from the drop down provided in that screen and click a view button. So, it is something like adding an actionListener or SelectionListener. But, i am unable to do it. Can anyone suggest me how to do it?
The class involving the following looks something like this.
public class MainHomePanel extends AbstractDtPanel {And the AbstractDtPanel looks something like this.
public abstract class AbstractDtPanel extends JPanelFinally, the method to create the Nodes is given below
    private void createNodes(DefaultMutableTreeNode top) {
        DefaultMutableTreeNode parentFolder = null;
        DefaultMutableTreeNode innerFolder = null;
        DefaultMutableTreeNode fileNames = null;
        ArrayList folderName = new ArrayList();
        ArrayList innerFolderNames = new ArrayList();
        ArrayList fileNameArray = new ArrayList();
        CommonUtil cu = new CommonUtil();
        folderName =cu.getFolderNames(sessionData.getSysPath());
        if(folderName != null && folderName.size() > 0) {
             for(int i =0; i<folderName.size(); i++) {
                 parentFolder = new DefaultMutableTreeNode((String)folderName.get(i));
                 top.add(parentFolder);
                 innerFolderNames = new ArrayList();
                 innerFolderNames = cu.getInnerFolderNames(sessionData.getSysPath(), (String)folderName.get(i));
                 for(int k=0; k<innerFolderNames.size();k++) {
                     innerFolder = new DefaultMutableTreeNode((String)innerFolderNames.get(k));
                     parentFolder.add(innerFolder);
                     fileNameArray = new ArrayList();
                     fileNameArray = cu.getFileNames(sessionData.getSysPath(), (String)folderName.get(i),(String)innerFolderNames.get(k));
                     for(int j=0; j<fileNameArray.size(); j++) {
                         fileNames = new DefaultMutableTreeNode(fileNameArray.get(j));
                         innerFolder.add(fileNames);
    }

Sorry, a small mistake. The "createNodes" method is in the "MainHomePanel" class.

How to trigger an ActionListener in different class on click of a tree node

Hi guyz,
There are three panels inside my main Frame
-->TopPanel,MiddlePanel and BottomPanel. I have a tree structure inside a panel. This panel along with couple more panels is in MiddlePanel. My main class is "mainClass.java". Inside that i have an actionListener for a specific button. I need to trigger that actionListener when i click one of the tree nodes in the panel i specified before. The problem is that my MiddlePanel is itself a different ".java" file which is being called in my "mainClass" when a specific button is clicked. There are different buttons in my "mainClass" file and for each one i am creating different MiddlePanels depending on the buttons clicked.
So, if i click the tree node, i need to remove the MiddlePanel and recreate the MiddlePanel(One that will be created when a different button in the mainClass file is clicked). i.e., i need to trigger the actionListener for that corresponding button. Is there a way to do it?

use this code to call different panel by selecting tree node.....ok

Tree Node Links

Hello,
I am trying to configure a Tree in APEX 4.1 and I'm not sure if what I am trying to do is possible. Here is the situation: I work for a university that has the following colleges:
College of Arts & Communication
College of Business Administration
College of Education
College of Liberal Arts
College of Professional Studies
College of Sciences
Each of the above listed colleges have multiple majors that are unique to that college.
So my tree uses the college name for the parent node and each of the majors for that college as the child nodes. Each Major has a major code assigned to it, so when a user clicks on a major, a page loads with information about the students in that major. Colleges, however, do not have a major code and so if the user clicks on the college name in the tree, the page loads but has no data. So, what I would like is that if a user clicks on a mjor, the pages loads like currently set up, but if the user clicks on a college name, a different page loads with information about that college.
So the question is: Is it possible to have one page load, say Page 21, when a major (child node) is selected, and another page, Page 22, when a college (parent node) is selected?
Thanks,
Bob

Yes, that is very much possible to call different urls/pages from different tree nodes. You need to format your query to use independent select statements (for each node) and finally use UNION to form the tree.
For example, you can do something like this:
SELECT CASE WHEN connect_by_isleaf = 1 THEN 0
            WHEN level = 1             THEN 1
            ELSE                           -1
       END as status
,      level
,      name as title
,      icon
,      id as value
,      tip as tooltip
,      url as link
,      seq as display
from
-- select statement for the parent node
UNION
-- select statement for the first/immediate child node
UNION
-- select statement for the level 2 child
start with parent is null
connect by NOCYCLE prior id = parent
order siblings by displayIn each select statement, you can specify the required link/url.
I hope this helps.

Creation of a Popup Menu for a Tree Node

Hi Ppl,
I need to create a Pop-up Menu for a tree node in WebDynpro Application, please give me a "How to .." sort of material or a link which would have same sort of information...
Also, My requirement is to call the pop-up on the right click of mouse on the tree node, please let me know on which event handler I can call it ? Do I require a custom event handler for it ?
Thanks in advance
Anish

Hi Anish,
You simply add a Tree UI element, and then right-click the tree UI element and insert a TreeNode element.
To the TreeNode element you can add a menu, and then to this menu you can add menu items. When the user right click the tree node, the menu item is displayed. If the user clicks the menu item, the action for the menuitem is run.
Hope that helps.

Reg: navigation from tree node to page

Hi
plz suggest me form where should i start. I have similar use case as given in this link

left side i have tree and right side corresponding pages.Whenever i click on tree node corresponding page should display.
How can i achieve this ?
Thanks

Calling a form from the main form

Hello,
As you can see here , i want to open a form, when i click on a subitem of ELEVI menu. so i did that, but that form is shown in the back of the main form.. i wanna that form being shown as a child form of the main form, or something like that..
also, i cannot close the second form, why?
the code for opening that form when clicking a submenu item is:
begin
     call_form('elevi', no_hide, no_replace, query_only);
end;Greets,

well, the menu for the called form does not exist, so i don't have any menu on this second form, just buttons. the code for calling the form when clicking the submenu item, is:
begin
     call_form('elevi',no_hide, no_replace, query_only);
end;but i still can open multiple times.. why? can u be please more explicitly on how to do this?
edit:
it worked like this: (didn't know if it's a good solution, but it works)
begin
     if id_null(find_form('elevi')) then
     call_form('elevi',no_hide, no_replace, query_only);
     else go_form('elevi');
     end if;
     end;Thanks for replies :)

You know that the sample you are referring to comes with the source code. You just have to click on the page source link to get to the source.
One way to archive this is to use a link element to render the node. The link can directly navigate to the right target or show the right region.
If you need something not sophisticated you can use a selection listener (http://www.oracle.com/technetwork/developer-tools/adf/learnmore/november2011-otn-harvest-1389769.pdf) and to everything from a bean method.
As you did not give any information about your Jdev version and how the tree is connected to the navigation it's hard to give more advice.
