Need to close the result table from my java application

Hi All

from my ImageJ java application, I am calling the "analyze
particles" application within ImageJ and as a result the "Result" table
is coming up.

Is there a way to close (or, kill) the "Result" table from my
application? I think I need the ID or pointer of the

Result window to close it ... or so, but not sure ... any help is much
appreciated.

By the way, I have to close the "Multi Measure" Menu or Table as well
(this is unwanted) - and I am not sure why the "Multi Measure"

is appearing in one computer and not appearing in other computer for the
same code, any suggestion?

Thanks
Tamjid

Re: Need to close the result table from my java application

have you tried using:

ImagePlus imageOfResultsTable = WindowManager.getImage(String titleOfTheResultsTable);
imageOfResultsTable.close();

?

Re: Need to close the result table from my java application

I'm sorry that was bad advice. I've just had a quick look at the source code for results tables. It's actually very simple- this plugin makes invisible the results window on my system:

import ij.WindowManager;
import ij.plugin.PlugIn;
import java.awt.*;

public class TestPlugin_ implements PlugIn {

public void run(String arg) {

Frame[] arrayOfFrames = WindowManager.getNonImageWindows();
for (int i = 0 ; i < arrayOfFrames.length ; ++i) {
String localName = arrayOfFrames[i].getTitle();
if ( localName.equalsIgnoreCase("Results")){
arrayOfFrames[i].setVisible(false);
}
}
}
}

Re: Need to close the result table from my java application

Thanks, BW, for pointing this out.

Like the solution that I found myself (and which I felt was unsatisfactory), this one has the problem that the Results table does not come back the next time an IJ.write() is done. Obviously, this one is better than my method, because it points the way to getting it back: do a setVisible(true) when writing to the table. I can do that in my own plugins, but if I use this in my plugins, they will cause problems when mixed with plugins that are outside my control but also use the Results table for output. Is there a still better solution, or is this a problem inherent in the Results table system itself?

Perhaps using the Results table for general output isn't a good idea. It doesn't appear that it was originally designed for that task, but I (and apparently others) have adopted it for that task because there doesn't appear to be a better solution within ImageJ. I'm still new to ImageJ. Is this the correct forum to make feature requests? If I decide to invest time in building a more complete version of this, is there a way to submit it to get it into the official build?

Re: Need to close the result table from my java application

All,

I am/have been using ResultsTables to pass general, array strructurable data
form one plugin to the next. For example, one plugin might detect objects,
the next extract object features, and a third run a pattern classifier on
those feaures. Right now, the only way to do this is to write the
ResultsTables to a text file using a ResultsTable.save(..) and then reading
them back in using ResultsTable.open(..) . This works, but having multiple
open the results table objects would really be nice.

Re: Need to close the result table from my java application

In reply to this post by Bob Loushin

@Bob

is there a reason you need to put data into the main ResultsTable with your plugin? I create my own instance of ResultsTable for my plugins, rather than share one with other plugins. It seems to work, you would have complete control over it's visibility and it allows a separate summary table etc.

Hi Bob, Tamjid, and everyone else involved:

wouldn't a simple close() instead of setVisible(false) do it?

Re: Need to close the result table from my java application

In reply to this post by Bob Loushin

Hi Bob,

I think you are right. Making it invisible without an easy mechanism to make it visible again is a bad idea. As you don't really want to be recoding all the plugins to check if the resultTable is visible when they add to it I think maybe adding a GUI to it would be sensible? You could always automatically minimise it to the dock.

For example (almost entirely written by my GUI builder/code in italics):

To call this from your plugin use the public static method: "MyResultsTableVisibilitySetter.getTheOnlyInstance();

NB: I've made no attempt to optimise hoe this looks- it's big and ugly.

import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;
import ij.WindowManager;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;

public class MyResultsTableVisibilitySetter extends JFrame {
private static final MyResultsTableVisibilitySetter THE_ONLY_INSTANCE = new MyResultsTableVisibilitySetter();
private JPanel contentPane;
private JToggleButton showButton;
private JToggleButton hideButton;
private final ButtonGroup onlyButtongroup = new ButtonGroup();

private MyResultsTableVisibilitySetter() {
addWindowListener(new WindowAdapter() {
@Override
public void windowClosing(WindowEvent e) {
do_this_windowClosing(e);
}
});
setAlwaysOnTop(true);
setTitle("Results Table");
setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);
setBounds(0, 0, 450, 300);
contentPane = new JPanel();
setContentPane(contentPane);
contentPane.setLayout(new FlowLayout(FlowLayout.CENTER, 5, 5));
showButton = new JToggleButton("show");
showButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
do_showButton_actionPerformed(e);
}
});
onlyButtongroup.add(showButton);
contentPane.add(showButton);

hideButton = new JToggleButton("hide");
hideButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
do_hideButton_actionPerformed(e);
}
});
onlyButtongroup.add(hideButton);
contentPane.add(hideButton);
pack();
}

public static MyResultsTableVisibilitySetter getTheOnlyInstance() {
THE_ONLY_INSTANCE.setVisible(true);
return THE_ONLY_INSTANCE;
}

protected void do_showButton_actionPerformed(ActionEvent e) {
boolean showTrueFalse = showButton.isSelected();
if (showTrueFalse) {
Frame[] arrayOfFrames = WindowManager.getNonImageWindows();
for (int i = 0 ; i < arrayOfFrames.length ; ++i) {
String localName = arrayOfFrames[i].getTitle();
if ( localName.equalsIgnoreCase("Results")){
arrayOfFrames[i].setVisible(true);
}
}
}
}
protected void do_hideButton_actionPerformed(ActionEvent e) {
boolean hideTrueFalse = hideButton.isSelected();
if (hideTrueFalse) {
Frame[] arrayOfFrames = WindowManager.getNonImageWindows();
for (int i = 0 ; i < arrayOfFrames.length ; ++i) {
String localName = arrayOfFrames[i].getTitle();
if ( localName.equalsIgnoreCase("Results")){
arrayOfFrames[i].setVisible(false);
}
}
}
}

if ( localName.equalsIgnoreCase("Results")){

}
}
this.dispose();
}
}

Re: Need to close the result table from my java application

In reply to this post by Michael Schmid

too easy!!

in all seriousness
1) I thought it might be useful to be able to make it visible very simply again with the measurements intact. You can always call reset() on the table if you want it clear.
2) Frame doesn't have a "close()" method so I think you would have to cast it to its subtype TextWindow, which is even more wordy:

Frame[] arrayOfFrames = WindowManager.getNonImageWindows();
for (int i = 0 ; i < arrayOfFrames.length ; ++i) {
String localName = arrayOfFrames[i].getTitle();
if ( localName.equalsIgnoreCase("Results")){
TextWindow tw = (TextWindow) arrayOfFrames[i];
tw.close();
}
}
[is there a way of getting a TextWindow object directly?? ]
3) close() would ask if you wanted to save the data. If you're not interested in the data that could be annoying.
4) I don't know much about the plugins being used but I thought there was a risk that they'd keep recreating the results table when they were re-run and it'd keep popping up. Although I guess there's the same risk with setVisible().
5) I don't think it would save that much memory to clear the table and dispose() of the window.

Re: Need to close the result table from my java application

In reply to this post by Md Tamjidul Hoque

There have been several responses to my last post on this topic, all of which offer interesting possibilities. I appreciate all the help. I will try to answer all of them here. Unfortunately, that may make for a longer than normal post, but if you read to the end, it comes to a happy conclusion, at least for me :).

First, some background. I'm relatively new to ImageJ, and I am using it because it is a useful tool to accomplish the data analysis I need to do. Most of my training is in science, not programming, though I do have an extensive background in C++ and some knowledge of Java. In order to use ImageJ, I need to write some plugins, so I poked through the ImageJ website until I found the ImageJ plugins tutorial and the appendix to Burger and Burge's book, both of which I've read fairly carefully. I've also peeked into the developers API Documentation in spots, but by no means exhaustively. So: limited knowledge of ImageJ, cookbooking from the tutorials, trying to get my analysis done as painlessly as possible. I think that's a fairly common plug-in writer profile. It also explains why I'm making so many mistakes and asking so many questions :).

More unique to my case, I'm producing a tool which will be used for routine measurements/analysis by people with no programming knowledge and only as much experience with ImageJ as they need to open files and run the tools. They will expect the user interface to be as simple as possible.

My application reqires a mechanism for presenting tables of mixed text and numbers to the user. I'm looking for a simple mechanism, easily controlled from a plugin, that allows me to show that table to the user. Preferably, it would be part of my plugins UI, appearing when the plugin starts, and going away when the plugin is done. It would also be helpful if I could update specific cells of the table without rewriting the whole thing. Superficially, the results table seems a perfect fit. It can present a table of data to a user with only a few simple calls, it shows up when needed, it goes away when you click on the red x in the upper right corner (although I can't find call which allows for the same thing to be accomplished from the plugin), and it comes back again when needed again.

@Michael Schmid Yes, close() would be a great solution, but it doesn't exist, at least at the level I'm trying to get at it (Frame class).

@Gabriel Landini Being able to read and update the data in the table would be useful, but in a very brief look at the API docs, there was no class named rt. Did you mean this to refer to the ResultsTable class?

@EHB2010 I think creating my own private ResultsTable-like window is probably the most correct (from a programming standpoint) solution suggested, and I looked around for a method to do that when I first ran into this problem. Unfortunately, I haven't found a mechanism for this in the docs I've mentioned above. That is, it appears to be more of a service (with one instance that appears when triggered by calls like write or setColumnHeadings) than an object which can be created and owned. If there is a mechanism for doing this, I would like to give it a try. There is a ResultsTable class which appears to be used to create this service, but, strangely, it has no close method. I suppose that sometime during the creation of the one we see on the screen, it gets wrapped or embedded in a frame or window of some sort, and that is what displays and closes it. I haven't had the time to delve into all that yet, but would appreciate pointers.

In a separate post, you give code for adding a GUI to the table. Thank you for investing that much time into my problem! I will try this out, but because of a busy schedule, that may not happen until next week. However, because of the nature of my application, I am trying to streamline the UI, not add more options to it. I'm sure this option will be helpful for others, however.

And in another post (just in), you suggest that the table can be closed if the frame is first cast as a TextWindow. This seems to work! It also passes the test of having the table come back again when it is called. And in my case, it does not ask to save data first. I think this is the missing piece to the puzzle, at least for my current application.

Summary: casting the Frame which contains the Results table as a TextWindow, then calling TextWindow's close, seems to answer the original problem. It would be good if there were a getTextWindow() function in WindowManager or something under it. It would be good if there were a method which roughly consisted of the following code, as copied from EHB2010's post (thank you!):

static IJ.closeResultsWindow() {

        Frame[] arrayOfFrames = WindowManager.getNonImageWindows();
   for (int i = 0 ; i < arrayOfFrames.length ; ++i) {
   String localName = arrayOfFrames[i].getTitle();
   if ( localName.equalsIgnoreCase("Results")){
   TextWindow tw = (TextWindow) arrayOfFrames[i];
   tw.close();
   }
   }
}

and assuming that using this doesn't break something else in the overall ResultsTable system.

Re: Need to close the result table from my java application

hi bob,

it was not my code. The GUI builder did almost all of it for me.

when you say "Unfortunately, I haven't found a mechanism for this in the docs I've mentioned above" I don't quite understand. You can create as many tables as you want for your plugin. For example run this plug in (italic portion):

import ij.plugin.PlugIn;
import ij.measure.*;

public class TestPlugin_ implements PlugIn {
public void run(String arg) {
for (int i = 0 ; i < 100 ; ++i) {
ResultsTable r = new ResultsTable();
r.show("table number "+i);
}
}
}

I'm not a programmer either, not a proper scientist either- I'm on a jaunt into science from working is hospital so I'll try not to talk too much nonsense.

However, I've been writing something which sounds like it may be similar in some respects to what you are trying to do. FWIW my advice would be collect all the measurements in a HashTable/class of your own writing so that you can have it specifically configured for your needs and write a controlling Swing GUI (with a GUI builder as it's incredibly dull) as
1) the users will like it and you can make it very simple for them to do everything. You can even select the right ImageJ tool for them etc.
2) as long as the window is alive it will maintain a reference to your HashTable of results so the results aren't Garbage Collected.
3) It will sort a lot of the threading issues for you. It'll look after itself, have it's own Event Dispatching Thread and you can start new worker threads from it to do the number crunching.
4) you can include a "draw table" button/action which takes the data from your HashTable and draws a fresh ResultsTable with all the data (or resets and redraws your original one). That way you get all the good stuff about the ResultTable class, like displaying and saving etc.
5) you don't have to delve to far into the ImageJ source code. For-instance I don't know enough of the source code to be sure which bits are and aren't thread safe (if any) so I make sure that all the interactions I make with ImageJ don't require ImageJ to be thread safe.

I guess one problem is that some of the measuring/plugins you plan on using will probably save their data to ImageJ's main results table, but you could just have an "import" button on your GUI to take the data into your HashTable.

that's my take anyway. If you go for it just remember not to use "myGUIFrame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE)", rather add your own window listener and close it down gracefully.

Re: Need to close the result table from my java application

I hadn't found much documentation on the functions in the ResultsTable class (as opposed to table which pops up when you use IJ.write) because there isn't much in either the plugins tutorial or the Appendix from Burger and Burge book referenced on the ImageJ website. I hadn't looked at the ResultsTable class in the API because I felt my issue (how to close it) was higher up, in the windowing control somewhere. Now that you've pointed this out to me, I will look more in that direction. You are right--you don't have to go too far into the code, if you happen to go in the right direction. I simply hadn't gone in the right direction. Thanks for pointing that direction out to me.

Re: Need to close the result table from my java application

Hi Bob,

the TextWindow class has a close() method. So you probably need
something like the following:

Frame frame = WindowManager.getFrame("Results");
if (frame instanceof TextWindow) {
TextWindow textWindow = (TextWindow)Frame;
textWindow.close();
} else {
SOME ERROR HANDLING (either frame=null or there is a non-
TextWindow window named 'Results')
}

TextWindow.close should take care of the rest: If the title is
"Results", it puts the results counter to zero and clears the
textPanel associated with the results.

In ImageJ 1.43s or later you can close the "Results" window using:

TextWindow win = ResultsTable.getResultsWindow();
if (win!=null) win.close();

or use

TextWindow win = ResultsTable.getResultsWindow();
if (win!=null) win.close(false);

if you do not want the "save changes" dialog to be shown.

Re: Need to close the result table from my java application

In reply to this post by Rasband, Wayne (NIH/NIMH) [E]

Hi Wayne

Problem #1:
========
with the following line the result-table window is now
suddenly reappearing (which was not happening before with the same code
same ImageJ version) in my java application and I do not want it be
displayed:
.......
Line# X: IJ.run("Set Measurements...", " redirect=None
decimal=2"); // This is just to minimize the possible computation and
insertion of the computed result into the ResultTable.
........
interestingly the result-table shows the previous run
results (expect in the case where ImageJ is just been reloaded) - as the
above line is called before any calculation - so just thought to report

this assuming there might be a bug.

Also, if I turn off the above line then things are all ok
(i.e. the result-table window is not dispalyed), though I call the
following line at the middle of the code later:

Line# Y: IJ.run("Set Measurements...", "area mean min shape
redirect=None decimal=9");

Problem #2:
========
To turn off the ResultWindow I am using the following code
as you advised before:

TextWindow win = ResultsTable.getResultsWindow();
if (win!=null) win.close(false);

But, within my batch mode java application (where noting is
displayed per operations) - the screen is blinking (due to close it as
early as possible but the same procedure is in a loop) very
badly. Could there a better option, such as setting the
resultTable window invisible or so?

Thanks
Tamjid

Re: Need to close the result table from my java application

Ok, to solve problem #2 (may be temporarily), I am using

... win.setVisible(false); // it will be in a loop unfortunately

in the first place and

... win.close(false);

at the end.

Any suggestion is welcome.
