• Best way to display a report of the hierarchy tree to APEX 4.2

  I have a hierarchical query spans four levels over two tables.  The application works very well and also includes columns hierarchical sum (i.e. the parent displays the sum of all children) using functions.

  I wonder what is the best way to view these data for users?

  At the moment I think I would have a collection now my connection with the edition special 'show' column.  Then I would include HTML to define values correct show/hide and refresh the report when you click on a node.  In my view, this would probably work, but may not be the best way.

  I disassembled my request for necessary columns (no column of the sum) and the tree APEX regions work well for this.  Y at - it a plugin alternative jquery or anything that people with what will give me the directory structure 4.2 native while allowing me to display additional columns with links?

  If I need to provide more info let me know!

  I'm going to use today to test these ideas, and if they don't work I'll go with the classic report hack, I thought.

  AEC: I'll try the plugin and report back on the question if I can get the links to work.

  The plugin code is clear and simple. However, the links generated HTML text in the query as:

  ...
  '' || apex_escape.html(ename) || '' employee
  ...
  

  does not work out of the box as the plug-in is escaping in HTML output column values:

      -- Render all other columns
      FOR j IN 3 .. l_value_list.count
      LOOP
        sys.htp.p('' || sys.htf.escape_sc(l_value_list(j)(i)) || '');
      END LOOP;
  

  This can be changed to allow the links:

    -- Render all other columns
      FOR j IN 3 .. l_value_list.count
      LOOP
       IF l_value_list(j)(i) not like '' || l_value_list(j)(i) || '');
      END LOOP;
  

• TREE OF APEX

  Hello guys,.
  
  What JavaScript is good develop only a single node?
  I have this code to develop the entire tree:
  
  tree_id = $('div.tree').attr ('id');
  apex.widget.Tree.expand_all (tree_id);
  
  But I only want one node, how do I do this?
  I have a button called: P22_SELECTED_NODE who receive the id of tree node.
  
  
  Thank you
  Raul Welter

  Raul,

  In my view, that the open_node function will do what you want. Current documentation (note that there is a newer version than what jsTree is in the APEX, but this should always be specific):

  .open_node (node, reminder, skip_animation)

  Opens a node closed, so that its children are visible. If configuration animation option is greater than 0, the children are revealed using a slide the bottom of the animation, whose duration is the value of the animation in milliseconds config option. Raises an event.

  Hope that helps,

• Problem with tree in Apex 4

  Hello
  I am currently working on trees at the Apex 4 using this query
  Select case when connect_by_isleaf = 1 then 0
  When level = 1 then 1
  of another-1
  end the status,
  level,
  "NAME" in the title,
  NULL as an icon,
  'ID' as the value,
  NULL as ToolTip,
  ? p = & APP_ID.:200220022 :'|| : APP_SESSION |': P200220020_R_K :'|| ' ' ID ' as link
  of ' #OWNER # '. " V_200_20_FTN_TREE ".
  Start with 'LINK' is null
  connect in advance 'ID' = 'PID '.
  brothers and sisters of order by 'ID '.
  
  The tree displays on the screen, but the challenge is that duplicate records. Please its urgent

  Couple of point

  a. the ID before link should be in single quotes? Although it is not the issue right now
  b. which is the column with the Id of the Parent of this tree? NEST. Therefore, PID which should go to start with the appropriate expression is null, or =. What condition must return only one line!

  Kind regards

• Default appearance of a tree of APEX

  Currently a tree on my apex request page loads fully developed mode. That is, all nodes and nodes are displayed.
  
  I have a need to load the page for all the collpased to its parent (not root level however) when the page is loaded.
  
  How can I get that without significant programming?
  
  Thank you
  R

  The simplest thing would be to set a property of tree Levels Max to a value that is not expand all levels.

• My own tree in APEX 4.2 icons

  Hello.

  I can't find any documentation on the correct syntax for the column "icon" of the SQL statement to create the tree. I don't know if it should be a URL, a class, no matter what...

  I've seen examples of the latest versions, but none works.

  If I write a string in the column of the icon, say 'custom_icon '.

  Select case when connect_by_isleaf = 1 then 0

  When level = 1 then 1

  else                           -1

  end the status,

  level,

  'CHI' as the title,

  "custom_icon" as an icon.

  'CHI' as a value.

  NULL as ToolTip,

  NULL as link

  Of...

  then I see on the generated HTML code

  < script type = "text/javascript" >

  var l39146525463344744Data =]

  {attributes: {'id': 'CERN'}, data: {"title": "CERN", "icon": "custom_icon", attributes: {}}, children: [...]}

  What should I do to show my own icon? I have icons in the workspace and associated with the application itself as well... I don't mind using a class for icons on my page...

  Thanks in advance

  Pedro

  Hi Pedro,

  I had one on my Example of Application, showing the use of the custom icons in a tree, where the name of the image must be prefixed according to its location.  For example, a standard image will be referenced as "#IMAGE_PREFIX #name.gif", an image of workspace as "#WORKSPACE_IMAGES #name.gif" and an image of the application as #APP_IMAGES #name.gif.  Our documentation is missing on this front, so we will ensure that it is updated to a future version.  I hope this helps.

  Kind regards

• APEX 4.0 how to build a tree?

  I am building a tree as an aid to navigation. There is no selection 'tree' in APEX under the shared components > Navigation.
  
  I found an article at http://www.apex-blog.com/oracle-apex/turning-a-tree-into-a-navigation-aid-17.html
  
  However, it does not concern APEX 4.0. This is for older versions of the APEX.
  
  So, I can't find any documentation about the construction of a navigation APEX 4.0 tree
  
  Can someone tell me how or where to find on the internet?
  
  I have created a simple "APEX_PAGES" table with my columns (ID, PAGE_NO, PARENT_PAGE_NO, NAME, NAVIGATION).
  
  
  Now what should I do?
  
  Thank you

  The change to this item of jsTree was not quite universally hailed. A number of people have experienced difficulties with the passage of the earlier implementation, or their expectations offered by the new features. Suggest that you search on the forum for more information. Don't comment on myself because I have made no use of the 'new' tree and only minimal use of the previous.

• ExtJS tree Plugin does not work with extjs 3.4.0

  Dear,
  I have used apex 4.2 and extjs 3.4.0 and I use Extjs tree Plugin, before I used extjs 3.4.0 tree plugin works well, after I used extjs 3.4.0 tree is not displayed
  I used this file called extjs

  <link rel="stylesheet" type="text/css" href="/i/ext/3.4.0/resources/css/ext-all.css">
  <link rel="stylesheet" type="text/css" href="/i/ext/3.4.0/ex3-1-local-viewport.css">

  <script type="text/javascript"src="/i/ext/3.4.0/ex3-1-local-viewport.js"></script>

  and I use it as a plugin in Ext JS Source directory
  default value: #IMAGE_PREFIX#ext/3.4.0/
  
  so why the tree does not now?
  Thank you

  Hi Ahmed

  You include Ext JS twice and two different versions.

  Delete this line

  In the future please create test on apex.oracle.com cases when you have questions, because it will be impossible to resolve otherwise. Also, do not forget that the use of Ext JS requires a valid license and so does the plugin to tree for APEX.

  See you soon

• Vertical scroll bar in a tree node

  Hi friends,
  
  I am trying to create a tree in Apex 4.0. I need a vertical scroll bar in my flowchart if no: values is greater than 8. For example, I have a tree with customers and sites. When I press the clients it will list sites for this customer. I need a vertical scroll bar is displayed for the sites if no: sites is greater than 8, so I can limit the size of the tree. Are there ways to achieve Apex 4.0. Any entry for this will be appreciated.
  
  Thank you

  You could combine all these properties in one class (inline of the div & fix Andy's IE styles) and assign it to the div.

    div.tree_scroll_div{
    overflow-y: auto;
    display: block;
    min-height: 10px;
    _height: 10px;
     }

  I have 2 problems. First is the link in a query (P28_TREE_ROOT) of the tree. In this version, I have links on each level, categories and departments are links and documents (files) that are in the hierarchy from the bottom and actually should be links. Question is: how to make a conditional link column in a query of the tree?
  Second problem is related to a sql database report in an area on page 28 (the same as the tree). The report is a simple SELECT query on a table of documents which, in consequence, gives all columns and all rows of the table. Question is: what is the condition WHERE should I do, to have only one line in the result, which would rank code of the document that has been clicked on a tree.
  Otherwise superior trees then documents could be links that give as a result with all report documents of the clicked Department or category...
  
  Thaks for help.

  Hello

  First of all, as you create a view that sees all three tables, you can add another field in each select statement that identifies the level involved. You can then use a CASE WHEN... Sql statement of PURPOSE for the LINK in your tree. You could, of course, create the LINK on selects it individual - even if it means hardcode the links within the sql view. If you set the LINK to set two values on your page - one indicator to identify the level and the other for the ID, then you have your report based on something like:

  SELECT ...
  FROM ...
  WHERE (:P1_FLAG = 'X' AND ID_DOC = :P1_ID)
  OR (:P1_FLAG = 'C' AND ID_DOC IN (SELECT ID FROM LIB_TREE WHERE PID = :P1_ID)
  OR (:P1_FLAG = 'D' AND ID_DOC IN (SELECT ID FROM LIB_TREE WHERE PID IN (SELECT ID FROM LIB_TREE WHERE PID = :P1_ID))
  

  There may be even simpler means using the SQL features own tree (see the CONNECT BY clause in SELECT statements: [http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/queries003.htm#sthref3139] - that is, in my view, how are constructed trees of Apex).

• How to change the region to fit on a single page when printing.

  Hi all

  
  

  I am only recently starting my APEX trip (and I am sure that this is where I want to stay!) please excuse any "dumb" comments I can do!

  
  

  I use APEX 5.0.3 and the universal theme.

  I followed the steps kindly provided by Christian Rokkitta on the following blog to create a tree of the Organization;

  Oracle & Apex Geekery: CSS3 Pure Org-tree with APEX list

  I only have a CSS and JavaScript knowledge, but did successfully a number of changes to meet our specific requirements. Where I fight, it's around areas of printing that do not fit on one page.

  I tried to edit the CSS, I tried to use JavaScript to open in a new window pop up, I have drawn on Print Style sheets and am currently using a modified version of the 'Standard' page template so that I can use @media Print to stop certain elements display. The CSS before I tried to use breaks page and updated scale, but after 4 days of work on anything else, but this printing problem, I'm starting to wonder if I go about it completely the wrong way.

  What is someone is able to help with the above? Basically, I need to make the organization chart fit on the single page when printing. almost as if I had 'zoom out' until it is on a single page and then print.

  I have refrained to put links or screenshots however please let me know if you need more information and I'll get it right above!

  Thanks to you all!

  Richard
