How to display file data in TextWindow or TextPanel?

[panovr]

Hi,
  I have a data file like this:
  20020704001 plugin
  20020704002 pluginfilter
  20020704003 pluginframe
  I want to read the file data and display them with headings "ID"
and "Name", the displaying results like the ImageJ's Results window:
  -------------------------------
         ID          Name
    1    20020704001 plugin
    2    20020704002 pluginfilter
    3    20020704003 pluginframe
  -------------------------------
  I read TextWindow class and TextPanel class, but don't know how to
do it.
  Thanks!

In TextWindow constructor like
: public TextWindow(String title, String data, int width, int height)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The second parameter "data" is what you desire to display.

To meet your needs, headings may be added by string operations.

Like this,
__________________________________________________
int count = 0;
String data = "\t\tID\t\tName\r\n";
// Suppose "str" is ONE record of your data file
data += Integer.toString(count++) + "\t\t" + str +"\r\n";
// Iterate the operation obove, it may produce the result you want.

Good Luck.

  However, this method can not set the headings of the TextWindow like
the ImageJ's ResultsTable class.
  What I want to do is:
  1. read the data from the file
  2. store every line into the ArrayList
  3. display one record per line in the TextWindow:
   -------------------------------
         ID                 Name
   1    20020704001 plugin
   2    20020704002 pluginfilter
   3    20020704003 pluginframe
   -------------------------------
  TextWindow uses TextPanel to display data, but I do not know how to
format and dispay data in it.

There are many TextWindow examples in the ImageJ source code. You can
find them by downloading the source from
<http://rsb.info.nih.gov/ij/download/src/> and using the Find macro at
<http://rsb.info.nih.gov/ij/macros/Find.txt> to search for
"TextWindow". Here are some of the ImageJ commands that use
TextWindows:

     "List" button in Image>Color>Show LUT
     "List" button in Analyze>Histogram
     "List" button in Analyze>Plot Profile
     Plugins>Utilities>List Commands
     Plugins>Utilities>List Shortcuts

You should also check out the TextWindow API at:

      http://rsb.info.nih.gov/ij/developer/api/ij/text/TextWindow.html

Hi,
  thanks Wayne for the help, now I can display the file data in a TextWindow.
  The data is like:

  1 20020704001 PlugIn
  2 20020704002 PlugInFilter
  3 20020704003 PlugInFrame

  This is the sourcecode:

import ij.*;
import ij.text.*;
import ij.util.*;
import ij.plugin.PlugIn;
import java.util.*;
import java.awt.*;
import java.awt.event.*;
import java.io.*;

public class Record_Display implements PlugIn {
       
    public void run(String arg) {
    listRecords();
    }

    public void listRecords() {
    File f = new File("plugins/demos/data.txt");
    FileReader fr;
    BufferedReader br;
    ArrayList<String> al = new ArrayList<String>();
    try {
    fr = new FileReader(f);
    br = new BufferedReader(fr);
    String s;
    String[] ss;
    while ((s = br.readLine()) != null) {
    ss = Tools.split(s, " ");
    al.add(ss[0] + "\t" + ss[1] + "\t" + ss[2]);
    }
    br.close();
    } catch (IOException e) {
    e.printStackTrace();
    }
    showList("Record Display", "Number\tID\tName", al);
    }

    void showList(String title, String headings, ArrayList<String> al) {
        String[] list = new String[al.size()];
        al.toArray((String[])list);
        StringSorter.sort(list);
        StringBuffer sb = new StringBuffer();
        for (int i = 0; i < list.length; i++) {
            sb.append(list[i]);
            sb.append("\n");
        }
        TextWindow tw = new TextWindow(title, headings, sb.toString(),
300, 400);
    }
}

  By the way, how can I find the source of the ImageJ's  Menu:
"File"->"Import"->"Text File..."?

Sincerely
Yili Zhao

Such things are encoded in the file "IJ_Props.txt", where it says:

      import05="Text File... ",ij.plugin.TextFileReader

hence it seems to be ij/plugin/TextFileReader.java

Sincerely

Joachim

Thanks for posting your solution.  It is interesting to see the your
method to get tabular data into ImageJ.
