:system.trigger_node_selected

How do I programmatically set the :SYSTEM.TRIGGER NODE SELECTED to true after a right mouse click on the node? I've tried the following:
Ftree.Set_Tree_Selection(htree, :SYSTEM.RIGHT_MOUSE_TRIGGER_NODE, Ftree.SELECT_ON);
This will highlight the node but it doesn't set the :system.trigger_node_selected to true.
thanks

Hi
How do I programmatically set the :SYSTEM.TRIGGER NODE SELECTED to true after a right mouse click on the node? I've tried the following:
Pls Have a look here.
In WHEN-TREE-NODE-SELECTED-trigger set the following Condition...
IF :SYSTEM.TRIGGER_NODE_SELECTED='TRUE' THEN
END IF;Hope this helps...

Web document opening twice

Hi all,
I'm working ona Forms10g application which uses a treeview as navigation menu.
Most of the treeview nodes simply calls a new form, one of them, though, is a link to an external webpage on a separate server.
When I click on that link the web.show_document works just fine and opens one new browser window with the desired content. But if I then click over a "form-calling" node then a second new instance of the document is open although the called form is correctly open in the original browser window.
This unrequested behaviour just occur the very first time I click on a node after having called the web.show_document built-in.
TIA,
Luca

I guess you call the link in the WHEN-TREE-NODE-SELECTED-trigger? If so, you have to check the SYSTEM.TRIGGER_NODE_SELECTED in your code for TRUE, because the trigger fires both on selection and de-selection.

Problem when selecting child node in Hierarchical Tree

I have a hierarchical tree on a form populated thru a table query(form1). When I click on a child node, it opens form2 which contains a tab canvas. After closing forms, I return to the form1(containing Tree). At this point If I want to click on the same child node, I should be able to open form2 again. This doesn't happen.
I have the following code in my When-Tree-node_selected trigger:
Declare
htree item;
vnode_label varchar2(50);
node_clicked FTREE.NODE;
vnode_value number;
vnode_depth number;
v_type number;
v_value varchar2(100);
v_form_name varchar2(100);
v_alert_return number;
begin
-- Find the tree itself.
htree := FIND_ITEM('tree_block.tree');
node_clicked := :SYSTEM.TRIGGER_NODE;
vnode_value := FTREE.NODE_label;
-- Find the value of the node clicked on.
vnode_label := FTREE.GET_TREE_NODE_PROPERTY (htree,:SYSTEM.TRIGGER_NODE,FTREE.NODE_label);
vnode_depth := to_number(ftree.get_tree_node_property(htree,:SYSTEM.TRIGGER_NODE,ftree.Node_depth));

end;
Can anyone please help me? I don't want the user to double click. They should only click once.
Thanks,
Mercedes

Right clicking does not change the current selection. The tree has no way to report what node was right clicked. Only work around is to left click the node you wish then right click it.

Hierarchical Tree and keyboard navigation

Does anyone know how to use Hierarchical Trees with keyboards, or to disable keyboard actions? (forms 9.0.4)
My form has a tree which does processing in a When-Tree-Node-Selected trigger to populate some blocks depending on the selected node. If the user selects nodes with the mouse then all is fine, but if they move between nodes with the keyboard then the processing for each selected node is only run the next time a node is selected with the mouse. This means the data for each node will flash up in the blocks for a split second when the mouse is next used.
I've tried Key-Up/Key-Down triggers to prevent keyboard navigation, but they don't fire. Setting Keyboard Navigable to false doesn't fix it either.
Using the When-Tree-Node-Activated trigger doesn't help. The online help says this trigger fires when the user presses Enter or double-clicks a node. I find that each node for which Enter was pressed is processed only when the user next double-clicks a node, and the node they double-click is not processed.

Ans: I wrote this code in WHEN_NEW_FORM_INSTANCE trigger. But the code didnot got compiled . I did cut and paste of query too.
Pls help me in defining the c_tree_blk_item_nm and go_node ( c_tree_root_node ). I was thinking some code of this type would work.
The code itself didnot got compiled. It didnot ran.
3) put this coding into WHEN-TREE-NODE-SELECTED trigger under the item, this is to populate the data to other block when u select the tree node.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
GO_BLOCK ( 'BK_AGT' );
EXECUTE_QUERY;
SYNCHRONIZE;
end if;
BK_AGT is the 2nd control block .
Help me in solution for this scenario in creating the hierarchical tree in forms6i.

WHEN-TREE-NODE-SELECTED

Hello alllll
i have a master-detail block besides a tree block
All i wanna do Simply and logically is to select a tree node then a Master-Detail records related to this tree node is to be retrieved...
_i have the following code in the WHEN-TREE-NODE-SELECTED Trigger as follow:_
DECLARE
htree ITEM;
 node_value VARCHAR2(100);
BEGIN
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
-- Find the tree itself.
htree := FIND_ITEM ('BL_TREE.IT_TREE');
-- Find the value of the node clicked on.
NODE_VALUE := FTREE.GET_TREE_NODE_PROPERTY( htree, :SYSTEM.TRIGGER_NODE , Ftree.NODE_LABEL );
 GO_BLOCK ('STP_COMPANIES');
EXECUTE_QUERY;
 END IF;
END;The above code retrieved data as a whole
but i want 2 filter the data selected from the tree node as i said 2 be displayed as filtered by the tree selection.
so i used the following code as follow:
GO_BLOCK ('GL_COST_CENTERS');
 set_block_property('GL_COST_CENTERS', DEFAULT_WHERE, 'COMPANY_ID ='||
 ftree.get_tree_node_property('BL_TREE.IT_TREE', :SYSTEM.TRIGGER_NODE, FTREE.NODE_VALUE));
EXECUTE_QUERY;Any help will be appreciated...
Thanks in Advance..
Regards,
Abdetu...

Hello thanks for reply,
STP_COMPANIES your detail block? no it's the master
gets the "Label" of the tree node not the value of the selected nodei tried both but nothing retrieved...!
i thought that the value is the serial of the node and the lable is the text displayed on the tree node no ?
Is this code in the same When-Tree-Node-Selected trigger or a different trigger?yes WHEN-TREE-NODE-SELECTED as my post titled...
is GL_COST_CENTERS the master block? no it's the detail ; every company --- has many <- cost centers
are the tables related? yes
just query the master table and the detail table will automatically be filter through the relationship?i did and it works filtering through the company_id, But what i wanna do is 2 filter the data displayed in the two block Master-Detail according 2 the selection of the tree
Say i selected the ....
 + Assets node
 |
 |------ - Furnitures 's node is selected so alll the related details of the furniture is displayed in the Master-BLock
 | |
 | +----chairs
 | |
 | +----tables
 |
 +----- LAnds
 |So the Tree is used 2 Query or retrieved the selected node's data accordingly...
hope i well explained my issue ..!
is it possible 2 do that ?!
Thanks Again..

Tree Node selected not firing all the time

I have a tree menu that calls other forms when the user selects a tree branch (see
When-tree-node-selected trigger below).
This works fine, but if the user closes the form and want to re-open it, the trigger doesn't fire unless the user clicks off the branch item and back on it. How can I make it work whenever the user clocks the branch item?
if :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' then null;
node_value := Ftree.Get_Tree_Node_Property(htree, :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE);
open_a_form(l_form,l_module,l_form_code);

The problem is the desc is not displayed NOT.
But the node id is working just fine..Why ?
Can anyone help me pls..?
i am using the following code:

END;Regards,

The WHEN-TREE-NODE-SELECTED trigger fires twice, it fires when selecting the node and when deselcting the node.
First make sure that you SQL works in SQL*Plus, Handle your EXCEPTION correctly, remove the NULL from your exception and put a message, maybe your SQL is not returning any rows.
add the below if condition in your trigger. This will make your code to be executed only when you select the node and not when you deselect it.
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
...    --Your execution code
END IF; If your item name is the node's label itself you can easily do this:
IF :SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE' THEN
:your_block.your_item := FTREE.GET_TREE_NODE_PROPERTY(HTREE$, :SYSTEM.TRIGGER_NODE, FTREE.NODE_LABEL);
END IF; Tony

Important tree question

hi all
please when i navigate in tree by mouse i want to get the node value and assign it to an item in the form( i get it by use when-tree-node-selected )
ftree.get_tree_node_property and get the value use system.trigger_node
but the question is :-
i want to get the node value when i navigate on tree nodes by keyboard not by mouse
which trigger i use and which code
if i use key-up, key-down triggers how can i specify the current node
urgent please
thanks

Hi!
You can use the same, the when-tree-node-selected trigger.
While the trigger fires, you can get via the :SYSTEM.TRIGGER_NODE_SELECTED variable,
if the fireing node either is selected or not because the trigger fires two times.
Onetime for deselect the left node and again for select the actual node.
You can use the following code to test the when-tree-node-selected trigger.
It fires on mouseclick and on keyboard navigation:
declare
htree item := find_item ( 'block.tree' );
begin
if
:SYSTEM.TRIGGER_NODE_SELECTED = 'TRUE'
then
clear_message;
message ( ftree.get_tree_node_property ( htree, to_number ( :system.trigger_node ), ftree.node_value ) );
end if;
end;Regards

OPEN FORM WHEN-TREE-NODE-SELECTED

hello all...
i have a tree and i wanna when i click on the node another forms open due to form name
i have table includes form_if,form_name " as in H.D.D"
when i present all nodes and i click on the node the form opened and when i click on other node from the tree
" the last previous selected node also opened and when i close it the new form is opened and so on"
the code in when-tree-node-selected is
DECLARE
node_value varchar2 (100);
frm_name varchar2 (100);
path varchar2 (100);
BEGIN
node_value := ftree.get_tree_node_property('block33.sub_TREE',:SYSTEM.TRIGGER_NODE, FTREE.NODE_VALUE);

frm_name:=null;
EXCEPTION

END;

Hi,

when-tree-node-selected

Fires when a node is selected or deselected.
So your code is getting executed for selection and deselection
use SYSTEM.TRIGGER_NODE_SELECTED to check

Tree node retrieving data for the 1st node only for 3 data blocks ?!

Hello alllll
i have 3 DATA BLOCKS MAster-Detail-Detail ; GL_TYPES -< GL_ACCOUNTS -< GL_COMPANIES
The Rel between 1 & 2 is

GL_COMPANIES.ACCOUNT_ID = GL_ACCOUNTS.ACCOUNT_IDi also have a Treewhich is retrieving data in the opposite data blocks the following code used in WHEN-TREE-NODE-SELECTED Trigger and it works fine but not for every node ;
the node selected shows data for the first node only; Say Assets but if i selected any other node it doesn't return any data ?
could any boady pls explain to me why is that happening ?
The following code is:
DECLARE
