Unique ResultsTable instance with clearing capabilities

[Josh Doe-2]

Right now I have a plugin which measures several unique statistics and adds
them to a ResultsTable. Right now I use ResultsTable.getResultsTable() which
gets the table used by Analyze>Measure titled "Results". This has problems
however.

If I use
my plugin to populate the table with values, and then procede to use
the Analyze>Measure tool, all of my results get deleted
without any prompting
whatsoever. Oddly, if I first use Measure and then use my plugin, then
measure again, results stay, though with the two
odd rows I added by using measure.

I tried just making my own instance of ResultsTable, but it lacks the
ability to truly clear the table (old "deleted" rows reappear when I do
another image). This is because only the window gets cleared, not the actual
ResultsTable. I see the code in the TextPanel and TextWindow classes
actually looks for the "Results" text in the title of the window to
determine whether to add the "Clear Results" menu and to provide for
selectively clearing rows.

Is there a way to have all the functionality of Analyze>Measure's
ResultsTable, without having these problems? I tried to subclass
ResultsTable, TextPanel and TextWindow to make things work, but it's gotten
so messy and it doesn't even work! I think the clearing functionality should
be built into an existing class or maybe another class, instead of TextPanel
and TextWindow using if(getTitle().equals("Results")). Thanks,
Josh D

How do you write to the Table?
Do you use:

rt.incrementCounter();
rt.setValue("Parameter", n, parameter_value);

If not, then you do not have any data in the Table, despite that you see
things printed in it.
For instance, if you use :
   IJ.write(parameter_value);
then you are not putting the data in the table, just showing it in there (it
took me some time to realise what is going on).

Also you have to check whether there is any data in the table if you want to
save it before writing to it. If there is data, then you prompt to save.

In one of my plugins I use (this is cut and pasted from several parts, so it
may not make proper sense, and mind the line breaks):

protected ResultsTable rt= ResultsTable.getResultsTable();

[...]
// are there any data?
if (rt.getCounter()>0) {

   SaveChangesDialog di = new  
SaveChangesDialog(IJ.getInstance(), "Save "+rt.getCounter()+"
measurements?");

    if (di.cancelPressed())
       return DONE;
    else if (di.savePressed())
        new MeasurementsWriter().run("");
}

rt.reset(); // resets the table
rt.show("Results");

and then I print the data to it.

at the end I call again
rt.show("Results");
so the screen is updated, but I am not sure this is mandatory.

I hope it helps a bit.

These bugs are fixed in ImageJ 1.38g, due next week. The
Sine_Cosine_Table plugin at

      http://rsb.info.nih.gov/ij/plugins/sine-cosine.html

demonstrates how a plugin can display values in the Results window.
