Binary tree Layout?

Hello, I need help. Please give me idea/tip/sample code how to build Binary Tree Layout.

For who don't know what is binary tree. Click on the link below...

Thank you...

There is no API for it, so I guess it's quite difficult to implement, you have to draw everything yourself.

You can watch http://www.blackberry.com/developers/docs/6.0.0api/net/rim/device/api/ui/component/TreeField.html
It doesn't look like your sample, but offers the features you want, I guess.

Similar Questions

need help with big O notation
I was wondering what is the huge cost of O to find the number of nodes in a binary tree, and what is the big O to find the sum of all values in a binary tree
from my understanding access a node in a binary tree takes o (logn) time.

To access a node.

So this means that to get all of the leaf nodes in a tree is just o (logn) then.

N °

And to get the sum of all the numbers in a binary tree must be straight of o (n)?

Right. Given that access to all nodes. So what's different from the previous case?

request for line lines - before using seq number
Hello

I have a table of records CatalogAuthor

long: id
varchar: author
long: seqnum

I made the table so that initially, if there are 10000 unique authors, then the lines will have numbers in sequence from 1 to 10000. When authors are added dynamically, they receive the sequence number of an existing line in the table, which is the nearest rank, which the author comes before the new author. Over time, there are more duplicates, and at some point, the table has all its sequence reassigned numbers to be monotonous increasing order of author name.

We want to use this table to generate a tree of about 10 knots by parent, which resulted in author names. So to expand the tree on the first level, we could divide 10000 by a power of 10 to get the number sequence groups. However, with double-seqnum, there may be 14365 lines so ideally, I'd sort of query to identify the record of 1436 in order sorted by sequence number of the record to 2872 by number of seq to overcome the problem of lumps, and so on.

What query would it? With the appropriate indices, it would still be slow? I do 10 of these requests to expand a node with 10 children? Is there a better design to achieve the same goal to explode a tree balanced by sort order of author name, which resulted in a map of a particular author?

Hi, Andy.

Hi Frank,.

I thought more about my problem and I realize that my column seqnum does not help much. What I'm really after is, let's say I have the column gap seqnum. Instead, I do author name an index on the table. Is there a query for the nth element in a column as an author?

What version do you use? From Oracle 11.2, theres NTH_VALUE. I don't know how is it effective.

For example, if I was building my own binary tree, and wanted to get the nth element, then I would have all the nodes in the tree to hold the number of knots-front. Updates the tree would always be logN.

I'm not you. If you have added a new node, which happened to be the first in order by the author, wouldn't change the value of nodes_before to all other nodes?
Total_descendants of count may be more what you are looking for. Adding a node would change only the County total_descnedants of his ancestors, and this number is proportional to log(n).

Search Google Navigation Tree Horizontal vs Vertical

Periodically, including now, Firefox displays the search navigation tree Google verses horizontally the usual layout page/vertical display. I noticed it tends to be after a restart of the computer and of course is not always a problem.

Special display in Google images to the vertical options limits horizontal navigation.

Thanks for the information on Google. I wasn't aware of this.

Somewhere in the clearing of all, this problem has been resolved. Ridicule me. I know that to clear cookies and cache when pop up Web pages display problems. Thanks for the reminder!

Canon MP495: Photo projects - family tree

I have a hp brochure supplied with photo paper indicating I can print my family tree and other projects by going to

www.HP.com/go/19homefun

However, this address leads me to snapfish and none of these projects is available here.

Still, HP does not offer photo projcts, especially the project of the family tree? Thank you for your help.

Hi FamilyProjects.

Many people use HP Photo Creations photo books to make family albums, adding images of certificates of birth and other memorabilia. Here are some pages of a book by Gary Lehman made called paintings by my great-grandfather. He was the big winner at our customer spotlight contest earlier this year.

With Gary for a book project photo print-at-home, double-sided pages that fall into an affair of pinch.

If you are in the Canada or the United States, there is also this model calendar with a family tree.

For the most flexibility, start with a Design-Your-Own collage print or photo book page. If you add multiple photos and then hold your shift key and drag through them, you will see alignment and controls of spacing that allows you to create your own layouts.

Let us know what type of project you are hoping to do and we will try to point you in the right direction.

HP Photo Creations is a free download on www.hp.com/go/hppc.

Hope this helps,

Incorporate the binary string in the string spreadsheet file

Hello LabVIEW wizards...

So I use scripture to VI file spreadsheet to create a beautiful layout, tabs-delimited report of one of my programs for the acquisition of data file. In one of the cells in the resulting worksheet file that I want to put a binary string of all my control values so when you open the data file all the control parameters used for its manufacture are restored, but the string is hidden when the report is displayed in Excel.

The problem is that the binary string flattened uses tabs and returns as part of its syntax the Spreadsheet File this VI to Write it's going in all directions. Worse yet, I can't unflatten chain when I open the file text because of "corrupt data or unexpected".

If I concatenate the string flattened with quotes around it she is superb and is placed in a single cell in Excel, but when I open the file in LabVIEW that she is still several elements in the array. I've isolated the binary string using the file VI text reading and got a subset of the quoted string, but it still unflatten correctly.

Essentially, I need to know how to get LabVIEW to pull a string literal full of special characters into a spreadsheet file and it unflatten. Any gurus what help you can provide is greatly appreciated.

Thank you

Jordan

I suggest that you change the formatting of your chain shipped by replacing the tabs and returns with other characters that are not considered as commands by the spreadsheet functions. Without knowing how you represent your control binary values, I can't offer specific characters.

If two non-printable characters exist which do not appear in the control data, it's easy: just find and replace tabs and returns with those characters. If there is no character, then something more complex needs to be done for example to escape special characters. Or create two subVIs - one to remove the tabs and returns before writing the string in the file and the other to restore after reading.

Looks like you are part of the many people that does not agree with the features that have been removed from Windows Explorer.

Installation of the classic interface can help. See the links below.

Unfortunately when Microsoft Windows Explorer, they made some pretty horrible decisions - which many people complained. There are a lot of other managers of files available, as well free and for a price. One of them might be easier to use and the characteristics you want, here is a list of the most that are available:

(2) fix the Bug of scrolling in the left pane: If you view a folder and expand in the left pane to display its subfolders, the folder is annoyingly prefer to the bottom of the component causing the subfolders do not appear, making it difficult to work with. Double click on a folder in the left pane can also cause this problem. Vote to fix it..

(4) the option to remember the view settings of each folder (Recalling the positions and sizes of the individual folder window).

(5) the option to remove 'Complete the selection of lines' to see in detail. "Selection of whole lines" is very annoying when the file is complete and has no empty space to click on. Also, when dragging / delete the file to another folder - if you release the on the line of a subfolder or file de.exe/.zip/.rar 'selection of whole lines' causes the file to be moved in the subfolder ou.exe/.zip/.rar instead file the file provided.

(6) a search engine with all the advanced search options. No required syntax.

(7) the option to always display free disk size space and record on the State and/or the details pane toolbar. Also always automatically show the size of the selected files (when several files are selected it will not show the total size).

(8) the option to show the pane that is your mouse with wheel mouse, even if this pane is not selected.

Using the classic interface to restore functionality of Windows Explorer

After you have installed the free Classic Shell , you can customize Windows Explorer more closely to how you want it, the quote below is just a way to do it. Click here to see some of the options that you can customize, and here is the FAQ page for the classic interface.

A solution that worked for the restoration of some features.

(1) install the free Classic shell. It's very customizable and works like a mod for Windows Explorer rather than a full blown replacement. You need to install the classic Start Menu option, but you can if you wish.
(2) restart the computer.
(3) launch Windows Explorer (Start - computer) and turn on "Always show Menus" (organize - Layout - check menu bar). It's just for the configuration, you can disable it again later if you wish.
(4) make a right click on the menu bar and turn in the "Classic Explorer bar. This adds a series of icons for cut/copy/paste in Explorer. Basically, it also adds the "Configuration" icon
5) go to the configuration and from there you can edit things to your heart's content. To kill the horrible record-jumping 7 Windows, place you Vista in 'Style Navigation pane. You can even hit back to XP mode if you want (this adds lines to the tree of folders and adds a classic icon "+" for the expansion of folders). The Windows Vista folder display style looks about the same as the view from Windows 7, but it gets rid of the horrible blow.
(6) adjust other settings you want.

After that, you can activate the toolbar and menus walk back to explore if you wish. Explorer Windows seems largely the same, but folders is no longer jumping around. Vote for Microsoft to fix this bug.

Now if only MS allows to code correctly so that we don't have to mess with third-party applications to get Windows actually works...

Why the tree in Explorer drop down when you open a folder in Windows 7?

I don't know what kind of joke someone plays, but it is not . I have already most likely to get surgery on both of my hands soon for carpal syndrome severe. For each round of a mouse wheel and all the clicks that I have to endure it's useless, my pain and my symptoms are growing more intense. I have 7 hard drives in my computer. I have search and locate and organize and delete and add files of ALL TIME. I'm in the Explorer of ALL TIME. It is deplorable that I had XP Pro because of threats of compliant. XP has at least had an Explorer who worked perfectly. Now of having to learn a new platform (Windows 7) and I am forced to support a program who has a child of 12 years could have better designed! How long still is * going to go? I discovered only recently that Explorer in Windows 7 has a tree that falls to the bottom of the page fricking every time that a file is opened, so I am forced to dive to the bottom of the page to locate the folder. So I started the research on the forums to see if I was losing my mind and just something wrong. I read messages from people complaining about this BS in 2007. Why is that, after 4 years this perverted arrogant control problem still exists?

Not able to read a text file or binary

I am reading in a file text or binary, as shown in the Blackberry "how - adds an application of plain text or binary files"

http://www.BlackBerry.com/knowledgecenterpublic/livelink.exe/fetch/2000/348583/800332/800620/How_To _...

I use Eclipse 3.4.2 I implemented a project of Blackberry with the following structure:

Test1 (project name)

-src (folder)

| + com.name.xxx

| + com.name.yyy

| Test1.Java

+ NET_RIM_BLACKBERRY

|

-test

I'm reading in the test file is at the level of the main project folder. For example, the Test1.jdp file is located in the folder of the main project and the test file (text file or binary). I am trying to access the file using the line of code below:
```
Class classs = Class.forName(this.getClass().getName());

InputStream is = classs.getResourceAsStream("/test");
```
The getResourceAsStream indicates that the file will be in the same location as the location of the Test1.jdp file if the bar oblique is in front of the name of the file, or that it will look in the source for the main class file. When I have the slash I get error

CAFETERIA: could not find the test file

I tried several different attempt to get to the CAFETERIA to find the file, but I'm running out of ideas and I would appreciate someone else's ideas on what to try.

Thank you

Thank you klyubin and stef

I found a solution that works for me with Eclipse plug-ins, JDE.

First, the example of Blackberry in the how-to (see original thread number) with test as file is named simply 'test '. This does not work for me at all in Eclipse. I gave up to place the file in the folder of the project Eclipse (main folder) and placed in the src folder, which of course gives a compile error because is not a Java file, and of course when using file name in my java code I changed the code correctly as in the first line that follows :
```
// this will look in the source folder of the class // that myClass refers tois = myClass.getResourceAsStream("test.txt");

// this is supposed to refer to a file called 'test' // in the source folder of the class that myClass refers to // but apparently for Eclipse it must have a .txt extension// as in the above exampleis = myClass.getResourceAsStream("test");

// this is supposed to refer to a file called 'test' // in the main project folder but not apparenlty for Eclipseis = myClass.getResourceAsStream("/test");

// this is supposed to refer to a file called 'test.txt' // in the main project folder but not apparenlty for Eclipseis = myClass.getResourceAsStream("/test.txt");             } 
```
Note: I was also getting the error message when I place the file named "test" in the src below directory. I managed to get rid of this error message by configuring the path building (similar to deleting the file of the JDP file including klyubin suggested above for Blackberry JDE ordinary rather than the plugin Eclipse) to remove the file 'test' for compiling so I would not get the compile error.

However, this was not my main problem - if you name the file test.txt and place it in the src directory you do not get this error I believe.

Errors during construction

Errors running builder "Blackberry resources Builder" on the project...

Could not compile files

java.io.FileNotFoundException: C:\path to the file I had added in the directory\.rrh of the source (or some truncation of the file name .rrh - for example te.rrh)

Finally, I have checked the jar (as klyubin suggested) file that is created when I place the file 'test' or 'test.txt' in my Eclipse project main folder. The jar file did not contain the name file and so when I run in the Simulator, the file is not found. Even when I put the file in the jar (main directory) myself the Simulator still could not find the file. When I placed the test.txt file in my directory src the jar resulting file contains the file named and the Simulator can find the file ok.

So, it seems to me that for the plug-in Eclipse JDE contextual explanation of the method getResourceAsStream does not apply as described at this time.

getResourceAsStream
```
public InputStream getResourceAsStream(String name)
```
Looking for a resource with a given name. This method returns null if no resource with this name is found. The rules looking for resources associated with a given class are specific profile. RIM implementation notes: this method searches the resource from the directory in which the current JDP project file is located. By default, it is assumed that this JDP file resides in the parent directory of the package of the current project space. Thus, the package space tree (for example, com/rim/PackageName) is added to name so that the search begins from this space package, that is, in the source directory of the current project. However, if the current JDP project file does not lie in its presumed location, the behavior above prevent the resource located. In this case, the user must add a slash (/) in the name of the resource before calling getResourceAsStream. This treats the name as an absolute path, which is compared to a tree whose root is the location of the JDP file. Parameters: name - name of the desired resource Returns: a java.io.InputStream object. Since: JDK1.1

If Alain klyubin (or someone else) can enlighten us more on why the file should be named *.txt to find the file in the source directory, which can be useful to me and others in the future. My real goal is to read in an image file named *.jpeg. We'll see how it goes.

And thank you klyubin for the suggested code change which I had also found in another thread...
```
// this was more than what was necessary//Class myClass = Class.forName(this.getClass().getName());

// this is simpler  Class myClass = this.getClass();
```
And so many other Eclipse users who try to follow the Blackberry How To - add a text or a binary file in an application, do not forget to consult the file name in your code java as in the examples that I gave above.

Tried the fix, still no tree to display in Windows 7 Pro (64-bit) folder

Windows 7 Pro (64 bit) on a new laptop HP dv7 Proliant. Windows Explorer is set to a display of libraries only. The classic file tree disappeared. The change means that I have to run two separate Windows Explorer instance if I want to move files from one folder to another.

I tried to selection of folder/organize and Search Options/view all files proposed in a previous answer to the problem, but still no display file tree. I also don't run Sfc - no problems found. So, is there a solution for this? Can I get the file tree view in Windows Explorer?

Note to the development team: libraries is the worst possible metaphor to treat files on a computer--especially for those who are still a little computer. In addition, forcing user files in folders on the disc of the operating system is a maddening practice which virtually ensures files will be lost when (not if) operating system crashes.

Have you tried actually organize / layout / Navigation pane?

Show all folders only too complicated the Navigation pane by inserting a bunch of folder in Favorites registration / uncheck show all folders.

Disable animation on the folder in the tree view

I noticed the same behavior and hate it as well, mostly because it doesn't happen not only in windows Explorer, but for each treeview control in any application (Windows?) during the expansion, the collapse or scroll one page upwards or downwards (using the key or the scroll bar, not when you use the mouse wheel!). Make sure that a parent element contains many elements of the child (> 20?), so for example using the "Program Files" folder in the navigation pane of Windows Explorer (activate it via the "organize" - "Layout" tab).

So far, I found a lot of message about this on various internet sites, but absolutely none of them explained how to fix or even only work-around her.

SQL query for the region of the tree

Hello
I was wondering if someone is able to help me work on a SQL query, to format the data in the table required in a part of the tree... I've never used a tree and I'm fighting to get the right data (if possible).
The data in the table looks like this:
I want to put it in a tree, using level 1 level6 with a final layout that would look like this:
As you can see, the data are formatted in level6 down in the tree, but are filled in the table from level 1. Not all of the columns will be filled, so level2 for anyone 4 (France) is the equivalent of level in the tree like level6 to person 1 (Spain).
This is Apex 4.2.5
Oracle 11.2.0.3.0
Sample data:
```
CREATE TABLE employees
   ( employee VARCHAR2(100),
     level1 VARCHAR2(100),
     level2 VARCHAR2(100),
     level3 VARCHAR2(100),
     level4 VARCHAR2(100),
     level5 VARCHAR2(100),
     level6 VARCHAR2(100)   
   );

INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person1','Team One','Recruitment','Human Resources','Fictituous Company','Murcia','Spain');
INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person2','Team Four','Testing','IT','Big Corporate','Hanover','Germany');
INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person3','Big Corporate','Hanover','Germany', null, null, null);
INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person4','Brittany','France', null, null, null, null);
INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person5','Team Three','Testing','IT','Big Corporate','Hanover','Germany');
INSERT INTO employees (employee, level1, level2, level3, level4, level5, level6) VALUES ('Person6','Public Relations','Government Agency','Brittany','France', null, null);
```
Added example given.

Hello

Apex-user wrote:

Thanks Frank, this is a good example, I can work with that! Your assumptions are correct.

A question I came, however, is that I have a data segment that comes across poorly formatted so to speak... where only the lower levels (1-2, etc.) have been filled from the bottom up.

An example of this data would be:
1. INSERT INTO employees (employee, level 1, 2, level3, level4, level5, level6) VALUES ('Person7', 'One Team', 'Test', null, null, null, null);
As you can see that if you rerun the select, the test team is now duplicated, both at the level of the root in the tree as it should.

You are not sure if the sql can be adjusted to account for this, or if it's too hard?

It is obviously a question of data and I am trying to solve this separately (extracted data from another system out of my control).

Thank you!

Sorry, I'm confused.

You say that my assumptions were correct. What includes supported that "If test ' occurs under 'IT' in a row, then the extent of the 'Testing' occurs, it must be under"IT "? Right after you say that assumptions are correct, you give an example where 'Testing' occurs under 'IT' to a single line, but it is not less 'IT' to another line and where is 'One Team' under 'Testing' in a line, but is 'One Team' under 'Recruitment' in another row.

When a situation like this occurs, how you cope? Whenever you have a problem, please post the exact results you want from the given sample data, and an explanation of how you get these results. If you don't know about what would be the ideal results, or if you are flexible on the exact results, then at least give an example and explain your reasons.

Maybe you want to change the got_parent of subquery like this:

WITH unpivoted_data AS

(

SELECT *.

Employees

UNPIVOT (node_name

FOR lvl (level1 AS 1

level2 AS 2

level3 AS 3

level4 AS 4

level5 AS 5

level6 AS-6

)

)

)

got_parent AS

(

SELECT c.node_name

MIN (p.node_name) AS a parent

Of unpivoted_data c

LEFT OUTER JOIN unpivoted_data p ON p.employee = c.employee

AND p.lvl = c.lvl + 1

GROUP BY c.node_name

)

SELECT LPAD (' ' ')

2 * (LEVEL - 1)

) || Node_name AS entity

OF got_parent

START WITH parent IS NULL

Parent = node_name PRIOR CONNECTION

;

In this way, if 'Test' is current 'IT' in one line, but not under what in another line, whether under would consider the 'IT' request and not to be a root. If 'One Team' sudden 'Testing' in a line, but under "Recruitment" in another line, it will be (arbitrarily) consider it under "recruitment".

My requirement is to create a tree node by using the option "Insert" through the context menu when the component of the tree is empty. By clicking on the option insert a node should be created in the tree. But currently the context menu don't appear unless a node exists in the tree of.

JDeveloper Version: 11.1.1.7.0

Fig - context menu to insert added to the Tree component

Fig - context menu is not display when no available tree node

The component of the tree grabs only necessary to render space and only in this space, you can access the context menu. As you do not have a jet of node, the space to make the tree is very small or didn't exist at all.

You can add a showPopupBehavior (pointing to the popup of context menu) to FY: tree which should give you the popup anywhere in the tree.

Hello
I have a region of the tree with the expand all / collapse all buttons. I need to format the layout a bit, by adding a vertical space between the buttons and the tree. Wondering if anyone has any suggestions? I tried to add an empty display element, but that did not help.
Thank you!

Hi Ryansun-Oracle,

In addition, one thing I forgot, I also a dynamic title shows a displayed element just above the tree. (Just added static text for the moment). When we use the margin option, the displayed item is not pressed. Is there a way to push the element displayed also down with the tree using a margin?

Thank you!

The region of the tree will now appear in the center of the region and the top margin, including the displayed item is pushed down. Here are the changes:
- Edition of the region of the tree and he gave a static id 'employee_tree '.
- Changing the page-> Inline CSS to:
```
#employee_tree div.rc-content-main {
    margin: 0 auto !important;
    width: 30%;
}
#employee_tree table.formlayout {
  margin-top: 10px !important;
}
```
I hope this helps!

Kind regards
