Example of tree area
HelloI 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.

Hi all
I am trying to build a region of the tree. I'm not an expert with who. I had the design of table like this:
ID Name1 name2 Name3 ,name4 1 Top_a Top_b Top_c Top_d How can I build a tree like these (with any default template that can expand/collapse)?
Top_a
Top_b
Top_c
Top_d
Please share ideas if someone did!
Thank you
Nabila
Thanks for your advice.
In fact, I can't change the structure of the table. I only works at the front end.
By the way, I solved using unpivot to build my as hierarchical query and I also implemented APEX DTree region plugin to add additional columns to show with tree node. My modified query is:
SELECT THE LEVEL,
name_value,
contract,
Recon,
difference
DE)
Select distinct column_name, regexp_substr (Column,'[[: digit:]] + [[: space:]] *') col_level, name_value;
regexp_substr (Column,'[[: digit:]] + [[: space:]] *')-1 p_level
from my_table
UNPIVOT
(
name_value for col_name (name1, name2, Name3, name4, name5, NAME6, Marque7, NAME8, NAME9, NAME10, NAME11, NAME12, NAME13, NAME14, name15)
)
Union of all the
Select 'Difference', ","Difference", 0
of the double
) accounts.
(select recon, contract of)
Select bookvalue, source_data
from my_table
)
Pivot
(
Sum (Bookvalue)
for source_data ("recon" as recon, 'contract' under contract)
)
) reconciliation
START WITH p_level = 0
CONNECT BY PRIOR Col_level = p_level

This specific example is something a little more complicated to ensure that lines which are parents of rows that meet the filter clause is also included in the query. Unfortunately I have no other documents available on this demo.

Files in the tutorial video example - where are they?

I find without the slightest trace of a such "sample files" in my Adobe directory or subdirectories. In addition, the video explaining the use of the 'drawing tools' to refer to an Oval shape tool; None of these tools oval does not lie in the Drawing toolbar. It's some small inconsistencies like this that make evaluate Flash Pro CS4 a negative experience. Where are the files of sample chapter?

the Oval tool is under the rectangle tool.
any tool that has a triangle pointing down will expose more tools when you press and hold on it.

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!

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.
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...

to find brothers and sisters to other tree trunk
Hello
I have a Table with objects [T (identification number, the field number)].
I have another table that links these objects in a structure tree [L (up_id number, down_id number)]. ~ (I need the child of beeing objects in more than one parent) ~.
Get the ID of a certain object (not the root, but it guaranteed not to have only one path to the root).
I have to find all the objects in the entire tree with the same value in the name attribute.
Usully I would go for connect prior down_id = up_id start with up_id is null but in my case there is no entry in L have up_id NULL. : () o

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). -
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:
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.Ext.BLANK_IMAGE_URL = '/i/custom/ExtJS/resources/default/tree/blank.gif';
Any ideas?
Thank you!
TammyHi 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 });

Pages are not properly displayed
Hi, I use OS X 10.9.5 and everytime I try to go to Gumtree, for example, no pictures are displayed.
Whenever I do a few tests online, pages will not display properly.
For example if I go to some of the apple sites, I always get the same questions and page does not load.
On some sites (e.g. Ebay), I get security warnings:
I also have some problems with I tried remove certificates, played with DNS and used all the tips I could find. However, none of them worked.

Example of C API communication LIN
Example for FLAX XNET uses no mode 'nxMode_FrameOutStream' or 'nxMode_FrameINStream' to 'nxCreateSession '.
Does this work in the context of LIN mode? If only they used to create the session for the same Interface?
I use ": memory:" in my database.
Can I get an example of work to help ": memory:" as of the databases with the mode 'nxMode_FrameOutStream' or 'nxMode_FrameINStream '?
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?
