• It is possible to hide elements during the publication?

  Hi guys,.

  My question: it is possible to hide elements during the publication?

  Because I would try to hide the buttons for export ^^

  Thanks for your help

  Quentin.

  Could you explain? Perhaps give an example? 'Éléments': you're talking about objects on slides? If you uncheck the 'Visible output' option - for versions 7 and earlier versions, or click on the eye icon in the properties panel for 8, this object will be invisible until make you it visible.

• Operations on the nodes of the tree

  Hi everyone, it's me again, with another question =)
  
  I need to be able to rename any node under a specific node in a hierarchy. Take this table and the following data samples.
  

  CREATE TABLE organisations
  (
    organ_id NUMBER(10) PRIMARY KEY, 
    parent_id NUMBER(10), 
    NAME VARCHAR2(255), 
    CONSTRAINT fk_org_to_parent_org 
       FOREIGN KEY(parent_id) REFERENCES organisations(organ_id)
  );
  
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (1,null,'Organisation 1');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (2,null,'Organisation 2');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (21,2,'Organisation 21');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (22,2,'Organisation 22');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (221,22,'Organisation 221');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (2211,221,'Organisation 2211');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (3,null,'Organisation 3');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (31,3,'Organisation 31');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (311,31,'Organisation 311');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (3111,311,'Organisation 3111');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (32,3,'Organisation 32');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (321,32,'Organisatin 321');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (3211,321,'Organisation 3211');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (3212,321,'Organisation 3212');
  Insert into ORGANISATIONS (ORGAN_ID,PARENT_ID,NAME) values (313212,3212,'Organisation with an id containing 31.');

  I would rename the tree nodes. For example, for example add the '-renamed "to all nodes under the node with the id of the organ = 31?
  
  I tried the following, but it is not good, because whenever I have another ID containing the number 31, I have an erroneous result.

  SELECT organ_id, lpad(' ', LEVEL * 2) || name, 
         -- sys_connect_by_path(organ_id, ','), 
          case when instr( sys_connect_by_path(organ_id, ','), '31') > 0 then 
             name || '- renamed' 
             else 
             name
          end
    FROM organisations
   START WITH parent_id is null
  CONNECT BY PRIOR organ_id = parent_id;

  The following query performs the work:
  

  select organ_id, lpad(' ', level * 2) || name, 
         -- sys_connect_by_path(organ_id, ','), 
          case when organ_id IN (SELECT organ_id 
                                   from organisations 
                                  start with organ_id = 31
                                CONNECT BY prior organ_id =  parent_id) then 
                name || '- renamed' 
             else 
             name
          end
    from organisations
   start with parent_id is null
  CONNECT BY PRIOR organ_id = parent_id;

  I wanted to know if it was possible without selecting sub?
  
  Thank you

  It is called the problem of 'Mother in chemotherapy', here's a way to solve it:

  SELECT organ_id, lpad(' ', LEVEL * 2) || name,
         -- sys_connect_by_path(organ_id, ','),
          case when instr( sys_connect_by_path(organ_id, ',') || ',', ',31,') > 0 then
             name || '- renamed'
             else
             name
          end
    FROM organisations
   START WITH parent_id is null
  CONNECT BY PRIOR organ_id = parent_id;
  

  In other words, don't look for '31', look at ", 31,

  The following query performs the work:

  select organ_id, lpad(' ', level * 2) || name,
  -- sys_connect_by_path(organ_id, ','),
  case when organ_id IN (SELECT organ_id
  from organisations
  start with organ_id = 31
  CONNECT BY prior organ_id =  parent_id) then
  name || '- renamed'
  else
  name
  end
  from organisations
  start with parent_id is null
  CONNECT BY PRIOR organ_id = parent_id;

  Reema,

  If you want your query to simpler tree, where, then add a column over in the tree as the "url" table, and specify the url to each table entry.

• Expand the node of the tree dynamically

  I have try the XML for the filter and open the tree node.

  var point: XML = xml... node. (@BH is argument); point is not null.

  tree. openItems = item; did not work

  tree. expandItem (point); also not worked

  tree. expandChildrenOf (point); still didn't work

  var p: * = tree.getParentItem (item); p is always null! ~~~

  tree. expandChildrenOf (p);

  The code you posted is slightly different from the one I proposed, after a while range of instruction you must call expandItem for element nodes [0]:

  tree.expandItem (node [0], true)

  So, you should try to replace the two lines that are placed below the one that is placed above.

  tree.expandItem (parentNode.parent (), true);

  tree.expandChildrenOf (PNode [0], true); / / not work

  Hi Sarah!

  If you fill your tree with a group of archives, simply add another line to this group
  and fill the tree with the build-in the set_tree_property ("block.tree", ftree.record_group, your_group_id).

  I can change the color of node using jQuery contains() selector based on a value, for example the project

  apex.jQuery("#eba_demo_tree").find("a:contains('Project')").css("color","red");

  Now, the question:
  How can I update the jQuery code to change the node based on a regular expression as

  ^[P]

  or in other words for all the nodes starts with P, the color needs to be changed in red?

• Find the element of list, table cell, node of the tree, or control by location

  One of my favorite on the swing features has the opportunity to get a reference to the component UI via Container.getComponentAt (int x, int y), or a particular list item through JList.locationToIndex (Point p) (or other similar methods). I was not able to find the same or similar functionality in JFX so far... anyone can point me in the right direction?
  
  Thank you!

  I don't know a way. When I started with JavaFX I had the same issue; However, I found that I actually need to do. Swing I ever need it when I was, say, treatment the mouse clicks on a JList. In JavaFX, you can register handlers with the cells directly. This does not work in the swing (in the least, not without a huge amount of effort). As well as in the swing, how to map a mouse click to a JList to the list item corresponding was to register a listener with the JList and then move the mouse click coordinates to locationToIndex (...), in JavaFX you just save the listener with the cell:

  import javafx.application.Application;
  import javafx.event.EventHandler;
  import javafx.scene.Scene;
  import javafx.scene.control.ListCell;
  import javafx.scene.control.ListView;
  import javafx.scene.input.MouseEvent;
  import javafx.scene.layout.BorderPane;
  import javafx.stage.Stage;
  import javafx.util.Callback;
  
  public class ListTest extends Application {
  
    @Override
    public void start(Stage primaryStage) throws Exception {
      BorderPane root = new BorderPane();
      ListView listView = new ListView();
      listView.getItems().addAll("Apples", "Oranges", "Grapefruit", "Bananas");
      listView.setCellFactory(new Callback, ListCell>() {
        @Override
        public ListCell call(ListView param) {
          return new CustomListCell();
        }
      });
      root.setCenter(listView);
      Scene scene = new Scene(root, 300, 300);
      primaryStage.setScene(scene);
      primaryStage.show();
    }
  
    private class CustomListCell extends ListCell {
      private final EventHandler listener = new EventHandler() {
        @Override
        public void handle(MouseEvent event) {
          System.out.printf("Mouse clicked on list cell with %s (item number %d)",getItem(), getIndex());
          if (isEmpty()) {
            System.out.print(" (Empty cell)");
          }
          System.out.println();
        }
      };
      private CustomListCell() {
        this.addEventHandler(MouseEvent.MOUSE_CLICKED, listener);
      }
      @Override
      public void updateItem(String item , boolean empty) {
        super.updateItem(item, empty);
        if (! empty) {
          setText(item);
        } else {
          setText(null);
        }
      }
    }
  
    public static void main(String[] args) {launch(args);}
  
  }
  

  Of course, maybe it's not your use case, and you really need this feature. Someone else can have a more direct response...

  Crossing hgrid himself will give the required node, no need to get the tree, please see the code below

  OAAdvancedTableBean adTBRN = (OAAdvancedTableBean) webBean.findIndexedChildRecursive ("advanced table id");
  OAHGridBean oahgridbean = (OAHGridBean) adTBRN .findIndexedChildRecursive ("RN HGRID ID");

• Setting the size of the trees

  Hello
  
  Is it possible to programmatically set the width and height of a hierarchical tree, based on the values containing in it?
  As if there are only 2 nodes in the tree, the size should be just enough to show the two nodes.
  If it has the largest number of nodes, the size should change accordingly
  Is this possible? (I use forms6i)
  
  Pls help
  Thank you

  Adkins,

  You can get the number of nodes of GET_TREE_PROPERTY integrated and can adjust its height by SET_ITEM_PROPERTY integrated. But it should be in the size of the canvas, otherwise it will give an error.

  Check the code below.

  DECLARE
     HTree        ITEM;
     Num_Count    NUMBER;
     Num_Height   NUMBER;
     Num_Y_Pos    NUMBER;
     Num_Required NUMBER;
  BEGIN
       HTree        := FIND_ITEM('.');
       Num_Count    := Ftree.GET_TREE_PROPERTY(HTree, FTree.NODE_COUNT);
       Num_Height   := GET_CANVAS_PROPERTY('', HEIGHT);
       Num_Y_Pos    := GET_ITEM_PROPERTY('.', Y_POS);
       Num_Required := Num_Count * 22;
       Num_Height   := Num_Height - Num_Y_Pos;
       IF Num_Required > (Num_Height) THEN
            SET_ITEM_PROPERTY('.', HEIGHT, Num_Height);
       ELSE
            SET_ITEM_PROPERTY('.', HEIGHT, Num_Required);
       END IF;
  END;
  

  I hope this helps.
