ij.Prefs and IJ_Prefs.txt

[Colin Poczatek]

I'm having some trouble understanding how to get/set preferences.  So
lets say that in IJ_Prefs.txt there's a line:

dir.image=/nrims/home3/cpoczatek/biggers_movie/

So when create a new ij.Prefs object based on the API docs it sounds
like it reads and parses that file, but I don't have a "dir.image" key
in that Prefs object.  What am I missing?  Do I need to call
prefs.load(Object ij, Applet a)?  ij should be IJ.getInstance()?  What
applet?

ij.Prefs prefs = new ij.Prefs();
System.out.println(prefs.get("dir.image", ""));

Just prints "" because it doesn't have the key.

And that is the default path you get when the user saves/opens/etc
right?  I mean imagej is looking at that file for the default path?  And
I should be able to call

prefs.set("dir.image", someotherstring);

Though it seems like the save button in a line profile plot defaults to
the ImageJ directory.  Bug?

Do you use the save command in your code?
Prefs.savePreferences();
Also I use the static version in my plugins, i.e., Prefs and not
ij.Prefs prefs = new ij.Prefs();

Personally, I use the Preference utility from Java to save my
preference and it work great.
import java.util.prefs.Preferences;

I was looking into this not so that I can store preferences for my
plugin, but to change the default open/save directory in imagej.

Since in our plugin data is getting pulled into imagej in a non-standard
way the 'dir.image' value isn't getting reset when you open an image for
our plugin.  Then any of the native imagej open/save dialogs don't
default to the same place.

Does that make sense?

Hi Colin,

what about OpenDialog.setDefaultDirectory(myDir);  ?
