Size 'height' of TextArea by number of lines?

I want my text boxes to be just large enough to hold the text. Is it possible to scale the height for the number of lines in the text?

Thank you.

In spark TextArea, there is a heightInLines property

Is TextArea - possible to get the number of lines?

I was wondering if there is a way to know how many lines of text one textarea. And also, if it would be possible to watch a number of lines changes. I'm developing a component that displays a single line in a first time and then starts to develop according to the needs, as the number of written lines increases.
Let me know if it is not sufficiently clear.

Thanks in advance.

Hello
Maybe what I am going to offer you is not the answer to your question. : P, but I have the same requirement, and I got the following. :)

I wrapped in TextArea with a StackPane, and before you add the text box in the StackPane, I added a label whose wrapText is true and related property prefWidth and text with TextArea, as below.

this.label =new Label();
this.label.setWrapText(true);
this.label.prefWidthProperty().bind(this.textArea.widthProperty());
this.label.textProperty().bind(this.textArea.textProperty());

That's all! It worked for me ;)

Here's the complete code for this new custom ;) control

ScrollFreeTextArea textArea= new ScrollFreeTextArea();

And the complete class:

import javafx.beans.value.ChangeListener;
import javafx.beans.value.ObservableValue;
import javafx.geometry.Insets;
import javafx.geometry.Pos;

public class ScrollFreeTextArea extends StackPane{

     private Label label;
     private StackPane lblContainer ;
     private TextArea textArea;

     private Character NEW_LINE_CHAR = new Character((char)10);
     private final double NEW_LINE_HEIGHT = 18D;
     private final double TOP_PADDING = 3D;
     private final double BOTTOM_PADDING = 6D;

     public ScrollFreeTextArea(){
          super();
          configure();
     }

     public ScrollFreeTextArea(String text){
          super();
          configure();
          textArea.setText(text);
     }

     private void configure(){
          setAlignment(Pos.TOP_LEFT);

          this.textArea =new TextArea();
          this.textArea.setWrapText(true);
          this.textArea.getStyleClass().add("scroll-free-text-area");

          this.label =new Label();
          this.label.setWrapText(true);
          this.label.prefWidthProperty().bind(this.textArea.widthProperty());
          this.label.textProperty().bind(this.textArea.textProperty());

                                                    .children(label)
                                                    .build();
          // Binding the container width to the TextArea width.
          lblContainer.maxWidthProperty().bind(textArea.widthProperty());

          textArea.textProperty().addListener(new ChangeListener() {
               @Override
               public void changed(ObservableValue paramObservableValue,     String paramT1, String value) {
                    layoutForNewLine(textArea.getText());
               }
          });

          label.heightProperty().addListener(new ChangeListener() {

               }
          });

          getChildren().addAll(GroupBuilder.create().children(lblContainer).build(),textArea);
     }

     private void layoutForNewLine(String text){
          if(text!=null && text.length()>0 &&
                         ((Character)text.charAt(text.length()-1)).equals(NEW_LINE_CHAR)){
               textArea.setPrefHeight(label.getHeight() + NEW_LINE_HEIGHT + TOP_PADDING + BOTTOM_PADDING);
               textArea.setMinHeight(label.getHeight() + NEW_LINE_HEIGHT + TOP_PADDING + BOTTOM_PADDING);
          }else{
               textArea.setPrefHeight(label.getHeight() + TOP_PADDING + BOTTOM_PADDING);
               textArea.setMinHeight(label.getHeight() + TOP_PADDING + BOTTOM_PADDING);
          }
     }

}

How to limit the number of line TextArea
Hello

I want to set the number of line TextArea to 1 initially. And I want the number of rows to grow dynamically as the user inserts "entry".
I could do it in javafx 1.3 with the lines property, in javafx 2.0 who disappeared. I tried to use the setPrefRowCount (.) but it does nothing (I guess because it's just a preferred setting).

How can I achieve this in javafx2.0?

Thanks in advance,

Nice workaround.

I think that this problem is fixed in 2.0.2, however: see http://javafx-jira.kenai.com/browse/RT-16827

Can I limit the number of lines of text entered into a TextArea?

Hello
I use Flex Builder 2 to create an application that allows users to enter text in different TextAreas and eventually create a PDF file with their different text. My only problem is that I can't limit the number of lines of text used in each text box. I can limit characters by using maxChar, but this does not take into account a user entering multiple presses "return" - this does not affect the character limit, but can result in the final PDF layout (spitting the text on page 2).
Is there a way to keep track and limit the number of lines of text in a text box (in Flex 2)?
(Ideally I won't disable the ability for users to use the 'back' button to create several paragraphs)
Any help would be appreciated.
Thank you
Ben.

Move and organize files based on the number of lines

Hello

I have a directory containing files nearly 1,500, some of which are composed of 12 lines, some of which are composed of 4 lines, which are all .phy (PHYLIP) files, which can be viewed in Notepad/wordpad as text files.

I need to execute a script which will determine the number of lines in each file and move them to the corresponding folder. The file size will not work for sorting, I've tried.

that is, all files with 4 lines in one folder, all the files with 12 lines in another folder, any files left (so I can be sure that everything has been inspected) in the main directory.

Can anyone help?

Thank you

Basic conditional script based on the number of lines in a text layer?

Just received help here to write a conditional script by using the font size of a text layer. Thank you all for this.
The next hurdle is a conditional script using the number of lines in a text layer in the differential. Far as I can tell it not the layer details which specify the number of lines. Just '\r' for a return in the idTxt descriptor. Nothing seems to stand for a soft return as far as I can tell. I'll probably have to be able to count the lines with soft and hard returns.
Any thoughts?

I was playing around with this a bit and here is a small script to determine the number of rows. This is based on the self in the head, that I calculated to environ.108 times the size of the font.
```
#target photoshop
app.preferences.rulerUnits = Units.POINTS;
var doc = activeDocument
var tL = doc.activeLayer
var h = tL.bounds[3]-tL.bounds[1]
var per = ((h/5)-(tL.textItem.size))/tL.textItem.size
var num = h/(tL.textItem.size *1.108)

alert(Math.round( num))
```

[ADF 11.1.1.4.0] How to know selected the number of lines without writing a bean
How to know the number of lines selected in ADF Table with EL Expression. We have estimatedRowCount (which gives the number of rows in the table) but I use cases where I want to activate a button (lets say 'Show' button) only when the selected row counts is '1' (not less or more) without writing ManagedBean.
You can follow my previous suggestion with a little change in the EL IE, without backing bean comes directly set table in the backingBeanScope instance.

For example.
#{! (backingBeanScope.t1.selectedRowKeys.size eq 1)} (notice no backing_table)

and bind the table binding property #{backingBeanScope.t1}

With the above code, there is no need to have a bean reinforcement or all java code, table instance will be called directly from backingBeanScope

Sample:

How to get the number of lines in a region of report
Hi all

Is there a way to get the number of rows returned in a report region, without issuing an another 'select count (*) from une_table?
I mean something like the substitution string #ROW_NUM # but for the total of the lines.

Thank you

Pedro.
http://download.Oracle.com/docs/CD/E17556_01/doc/user.40/e15517/UI.htm#CHDDGGEG

For parts of classic report, the footer region supports the following substitution strings:

#ROWS_FETCHED # indicates the number of lines read by the reporting engine Oracle Application Express (the size of the page). You can use these substitution strings to display messages to the user. For example:

Read #ROWS_FETCHED # #TIMING # seconds lines.

* #TOTAL_ROWS # displays the total number of rows that satisfy an SQL query used for a report.

#FIRST_ROW_FETCHED # and #LAST_ROW_FETCHED # show the range of displayed lines. For example:

Until #FIRST_ROW_FETCHED # by #LAST_ROW_FETCHED # of #ROWS_FETCHED # displayed >

How sample effectively a fixed number of lines
Good afternoon. I need to select a number of random rows in a table, and even if I think that my logic is good, it takes too much time, 30 minutes for a size of current data. I hope someone here can show me a more efficient query. I saw the EXAMPLE of function, but only randomly, he selects lines on a basis of one by one, without the guaranteed total number.

This is the idea:
```
INSERT INTO Tmp_Table (Value, Sequence) SELECT Value FROM Perm_Table, DBMS_RANDOM.VALUE;
SELECT Value FROM Tmp_Table WHERE ROWNUM <= 1234 ORDER BY Sequence;
```
I need to put the ORDER BY in a subselect for ROWNUM works fine, but in any case, it is only an illustration. My real need is a bit more complicated. I have several sets of data; each game has multiple lines; and for each game, I need to return a (different) specific number of lines. Project A has maybe three lines in this table, and I want to keep both of them; Project B has two lines, and I want to keep one of them. So I need to identify, for each line, it is valid for this project. That's what my data looks like:
```
Project Person  Sequence Position Keeper
A       Bill    1234     1        Yes
A       Fred    5678     3        No
A       George  1927     2        Yes
B       April   5784     2        No
B       Janice  2691     1        Yes
```
I fill the sequence with random values, and then calculate the position of each person within their project, and finally throw people who are Position is superior to Max_Targets for the project. Fred and April had the highest number at random, so they are cut off. It is not the case I'm just carve out a person of each project; the actual percentage kept going from zero to 100.

Fill the list with random values is not tedious, but is calculation of Position. This is my code:
```
UPDATE Tmp_Targets T1
 SET Position =
  (
  SELECT
   COUNT(*)
  FROM
   Perm_Targets PT1
   INNER JOIN Perm_Targets PT2 ON PT1.Project = PT2.Project
   INNER JOIN Tmp_Targets T2 ON PT2.Target = T2.Target
  WHERE
       T1.Target = PT1.Target
   AND T2.Sequence <= T1.Sequence
  );
```
The target fields are PKs, and Project and sequence fields are indexed. Is there a better way to address the issue? I could write a slider coming out project codes and performs the operations above for each project in turn. that would be logically easier and perhaps faster. Has anyone here addressed a similar problem before? I would like ideas.

It's about 9.2, in which case it is important. Thank you

Jonathan
You have not given any indication on how max targets for a given project is determined, so for my example, I use the ceiling of 1/2 of the number of records in each project that gives the same number of Yes and no answers by project you have had:
```
with dta as (
  select 'A' project, 'Bill' person from dual union all
  select 'A', 'Fred' from dual union all
  select 'A', 'George' from dual union all
  select 'B', 'April' from dual union all
  select 'B', 'Janice' from dual
), t1 as (
  select project
       , person
       , row_number() over (partition by project order by dbms_random.value) ord
       , count(*) over (partition by project) cnt
       , rownum rn
    from dta
)
select project
     , person
     , ord
     , cnt
     , case when ord <= ceil(cnt/2) then 'Yes' else 'No' end keep
  from t1
  order by rn

PROJECT PERSON ORD                    CNT                    KEEP
------- ------ ---------------------- ---------------------- ----
A       Bill   2                      3                      Yes
A       Fred   3                      3                      No
A       George 1                      3                      Yes
B       April  1                      2                      Yes
B       Janice 2                      2                      No   

5 rows selected
```
In this example, I use an analytic function to assign a random ranking for each record in a project in the intermediate query, in the final output query that I'm determining the Yes not according to the order in a project and the number of records in the draft statute. If you had a project table indicating the thresh hold you could join and use the thresh hold instead of part ceil(cnt/2) of my inequality in the case statement.

Hi Misha,.

The County appears at the bottom left of the page and it shows more options when you click on it. Unfortunately, "number of lines" is not included in the available options:

If you had ' 09 Pages on your Mac and did not intentionally removed it when you installed 5 Pages, it will always be there, in a folder named iWork ' 09, in your Applications folder.

Copy your document, open the Pages ' 09 and paste the contents of your document into a word processor new document in Pages ' 09.

Check that the end of the document is delivered on the same page (number) and to the same position on this page as in the original and making small changes at the margin to adjust it if necessary.

Then go to edit > tools > statistics to see this more comprehensive report:

Note that if you need to present the newspaper article in one format other than a file of Pages, the number of rows may change due to changes in the conversion to the new format of formatting.

If you don't have a Pages ' 09, you can get a number of lines using tools > line numbers in OpenOffice or LibreOfficeApache. Both are applications open source, free to download and use (even if you might donate help the future evolution of the demand). The links will take you to their respective Web sites.

Oh... One more thing (as long as Steve jobs used to say sometimes): pages (3), go (menu) Pages > provide pages of comments and make a feature request so that the line count (and line numbering) added the capability of 3 Pages.

Problem with the number of lines in the channel

Dear community LabView,

I'm relatively new to labview and I came across a problem that (I assume) can easily be resolved with your help.

I need to create a digital signal to trigger a camera, but I have a problem with the configuration of my lines or exit lanes. I would not use that line output to trigger the camera. (I use a card NI PCIe-6353). LabVIEW is telling me that the number of lines in the channel does not have the number of rows of data:

Possible reasons:

Specified read or write operation failed because the number of rows in the data of a string is not the lines in the channel.

If you use the digital waveform data type, make sure that the number of lines in the digital waveforms is the number of lines in the channel. If you are using Boolean data, make sure that the dimension of the array for the rows of the data is the number of lines in the channel.

Number of lines in the channel: 1
Number of data lines: 2

Task name: _unnamedTask<11>

How and why the number of data rows is connected to the resolution of my analog digital converter?

I would appreciate your help! Labview code and a screenshot attached.

Thank you

I got it to work by changing the "data format" "binary not signed" OR by plugging is not the "offset" for the Square Wave VI. I think that the default "offset binary" data format works correctly if there is a negative value.
