Example of tree area

Hello

I use my apex.oracle.com workspace. I am creating a region of the tree using the emp table. I use the typical Wizard but when I run the page in the tree is not displayed.

This is the query that is generated by the apex with the wizard.

Select case when connect_by_isleaf = 1 then 0
When level = 1 then 1
of another-1
end the status,
level,
'ENAME' as the title,
NULL as an icon,
'EMPNO' as value,
NULL as ToolTip,
NULL as link
of ' #OWNER # '. " EMP.
Start by "MGR" is nothing
connect prior "EMPNO" = "MGR".
siblings arrested by 'ENAME '.

http://Apex.Oracle.com/pls/Apex/f?p=41771:3:8143710593092:

Run the page: works fine - no errors.

Run SQL workshop:

No data found.

Very well. Then of course the bound data.

select * from emp

16 rows returned

Large.

Connect to start with the clause:

start with "MGR" is null

Oops. No record where "MGR" is null. Not a tree!

    The effects of top 3 (flame, frame photo and tree) are grayed out in photoshop CC2015. How can I activate them?

    Well, I have a full card on my Mac, I do not have access to the 3D features, so I mounted make flame, frame and tree on my Windows 7 Dell.

    First created a new empty file, then 3D > new mesh layer > 3D postcard workspace if requested.

    Then I went to the filter > make > Frame and try the command again. Frame, fire and trees is active and is more gray.

    Then on the Dell, I went into Photoshop preferences > sync and transferred all settings.  (you can install Photoshop on both machines)

    On my Mac, I went into Preferences > settings sync and uploaded everything and rendering filters have been activated on the Mac and they work well.

    The point is that you should be able to activate the filters of rendering on your Mac. Otherwise install Photoshop CC 2015 2015 on a second computer, activate the filters it and sync the two as explained above.

  • NULL values for some elements of the XML reading tree

    I am confirming that I interpret correctly all the elements of a custom data XML structure defined by my application (the schema is completely under my control).  Some of the elements in my XML tree are read as NULL values, even if similar items are readind as expected.  I have checked some obvious things like misspelling the names of keys, but have not yet find the problem.  Anyone who has debugged similar questions - what else could cause this?

    Example XML:

    
        1.0.0.0
        1000
        MyAppsName
        
            
                1000
                userDefined
                StructName
            
        
    
    

    And extracted C++ w/comments at the end of each line about what I see (DataManager is my class of CRUD operations):

    In DataManager.hpp:

    QVariant mCustomDataStructsTopLevel;
    QVariantMap mCustomDataStructsTopLevelMap;
    

    In DataManager.cpp:

    mCustomDataStructsTopLevel = mXda.load(Utils::dataFilePath(customDataStructsFileName));  // XmlDataAccess; verified loading w/no errors
    mCustomDataStructsTopLevelMap = mCustomDataStructsTopLevel.toMap();
    
    qDebug() << "appName element value: " << mCustomDataStructsTopLevelMap["appName"]; // Outputs "MyAppsName" as expected
    qDebug() << "lastId element value: " << mCustomDataStructsTopLevelMap["lastId"]; // Outputs null (specifically: QVariant(, ) ) - this is NOT expected
    qDebug() << "appVersion element value: " << mCustomDataStructsTopLevelMap["appVersion"]; // Outputs null (specifically: QVariant(QString, "") )  - this is NOT expected
    

    OK, I got the feeling (and actually hoped) it was a silly mistake of face-palm on my part (compared to a problem of BB10 who had little chance of getting fixed).

    The problem is that I copy the structure of custom data from Starter to my Active dir to my data directory to first install but do not crush him on subsequent launches, as the copy in the data directory is what the user changes and relies on.  I was not a delete and reinstall on each of my iterations, so I wasn't really loading the modified versions of my XML I wanted--just, I was getting a day old stale version which was actually for the items I didn't expect NULL values for nulls.  DOH!

  • How use TreeExpanderWidget, there is no example or specification on this widget, can someone tell me how to use it thank you.

    Now, I have a TreeView, it works fine.  But all the elements in the tree are displayed directly, I want that the collapse at the beginning and just expand on click, like the following image event.treeexpander.jpg

    I searched all the SDK, there is no example of this.

    could a few examples or tell me how to configure these settings. Thank you.

    Usually, a tree is created with nodes is collapsed. Are you sure that you do not have somewhere call ITreeViewMgr::ExpandNode()?

    If your expanded nodes only reflect the previous state, the commentary to the header in ITreeViewMgr::ChangeRoot() mentions ClearTree (kTrue) for exactly this case...

    ... I was wondering if the name that (...), select help here...

    Subqueries certainly help. They do not have to be in a WITH clause. views online would work in this case.

    I have to respect the tree structure, because the table contains several separate trees...

    In a tree, each node has only one parent (if any). In my_tree_links, id = 26 has two parents (10 and 20), so this isn't a tree. You not helping yourself or someone else if you say it is.

    INSERT INTO my_objects
    SELECT LEVEL
    , mod (LEVEL,7)
    FROM DUAL
    CONNECT BY LEVEL < 27;
    /
    

    When end you a statement with a semicolon followed immediately by a slash, then the statement is executed twice. I suppose that this isn't what you wanted. If my_objects.id is not unique, the solution below will have some minor changes.

    To limit the results to the nodes that have an ancestor with the target node, you can do a Query of Yo-Yo , where you do a query of bottom-up first, to find all the ancestors without parents of the target node, then do a query from top to bottom, to find all their descendants, like this:

    VARIABLE     target_id     NUMBER
    EXEC  :target_id := 26;
    
    WITH     got_roots     AS
    (
         SELECT     id_up
         FROM     my_tree_links
         WHERE     CONNECT_BY_ISLEAF     = 1
         START WITH     id_down     = :target_id
         CONNECT BY     id_down     = PRIOR id_up
    )
    ,     got_descendants     AS
    (
         SELECT     id_down
         FROM     my_tree_links
         START WITH     id_up     IN (
                             SELECT     id_up
                             FROM     got_roots
                           )
         CONNECT BY     id_up     = PRIOR id_down
    )
    SELECT DISTINCT
         mo.*
    FROM     my_objects     mo
    JOIN     got_descendants     gd  ON     mo.id     = gd.id_down
    WHERE     mo.value     = (
                        SELECT     value
                        FROM     my_objects
                        WHERE     id     = :target_id
                     )
    AND     mo.id          != :target_id     -- If wanted
    ;
    

    Output (where: target_id = 26):

    `       ID      VALUE
    ---------- ----------
            12          5
            19          5
             5          5
    

    Always tell what version of Oracle you are using. The query above works in Oracle 10 (and), but could be adapted to run on Oracle 9.

    Whevever you need to do a CONNECT BY query as a join, it is faster if you can CONNECT BY first, in a separate subquery and join the results for the other tables. This is what the second auxiliary request, got_descendants, is for.

    What results would you if: target_id = 8?
    The query above, as written, would not include id = 1. If you want, you will need to somehow enter the root ID for example 1, which are never id_down, in the same column with all the id_downs. You can do it with a UNION in the query, but you can change permanently my_tree_links so that these roots have some parent (themselves or some dummy, like NULL).

  • Ext tree images

    Hello
    I'm trying to implement example of tree of Tobias (http://apex.oracle.com/pls/otn/f?p=65555:38) but I'm having a problem get the images folder/sheet is displayed.) I know it's probably something stupid I'm missing, but I can't understand it. I have the following line in my .js file:
    Ext.BLANK_IMAGE_URL = '/i/custom/ExtJS/resources/default/tree/blank.gif';
    And I made sure the path to the images in the file ext - all.css was correct. When I run the page, the images in the tree are all empty. When I remove the line above my .js file, the pictures in the folder and the leaves appear, but blank.gif image does not (obviously). So I don't think it's a matter of my image path err, but when the Ext.BLANK_IMAGE_URL is set, it's like folder/sheet images do not exist.

    Any ideas?
    Thank you!
    Tammy

    Hi Tammy

    You get further and further the right answer.

    First, you must copy all of the Ext files on your web server, keeping the structure of folders.
    The file ext - all.css uses relative paths to reference images, so you have to keep the existing structures of the file.

    Second, the solution of Ext.BLANK_IMAGE_URL I have given is correct and must come before the code for your tree

    i.e.

    Ext.onReady(function() {
       Ext.BLANK_IMAGE_URL = '/i/1px_trans.gif';
    
       // your tree code
    });

    Hi mahajan24,

    The XNET Hardware and software manual discusses the use of Frame Output Stream Mode with LINEN, so it would be interesting to look into methods that they discuss. I have included a link to the page in the manual. Values of LIN frame transmit on the network in operation when XNET write is called. It is recommended to use XNET write (LIN frame), but you can also use XNET write (Raw image) for more advanced applications.

    Frame Mode output stream: http://www.ni.com/pdf/manuals/372840k.pdf#page=93

    Examples of shipping more focused on getting started you, you can try using the Output Stream Mode setting and change until inspired to look at how other examples of output are implemented.

    In addition, regarding the error you see, this could be because your device needs an external power supply. LIN usually requires the bus power. What specific chassis PXI and LIN / other cards do you use?
