Persisting State In java.util.prefs or Somewhere Else?

[Alan Brooks]

I am using the newly available Toolbar.setIcon() method to provide the ability to set a visualization configuration that is persistent across ImageJ sessions. I am currently using java.util.prefs.Preferences to accomplish this, as shown below. Is there something for user preferences within ImageJ I should be considering instead?


isOn = eval("script", 'java.util.prefs.Preferences.userRoot().getBoolean("ab.rotator.isOn", false);');
if (isOn=="false") {
   call("ij.gui.Toolbar.setIcon", "Toggle Rotator Action Tool", "Cc00V00ff");
   eval("script", 'java.util.prefs.Preferences.userRoot().putBoolean("ab.rotator.isOn", true);');
   showStatus("Rotator enabled");
} else {
   call("ij.gui.Toolbar.setIcon", "Toggle Rotator Action Tool", "C00cF00ff");
   eval("script", 'java.util.prefs.Preferences.userRoot().putBoolean("ab.rotator.isOn", false);');
   showStatus("Rotator disabled");
}

Thanks,
Alan

You can use the Prefs.set() and Prefs.get() methods. Here is a version of the "Toggle Icon Action Tool” that uses these methods:

   macro "Toggle Icon Action Tool - C037N44F00nn" {
       state = call("ij.Prefs.get", "toggletool.state", "box");
       if (state=="box") {
          call("ij.gui.Toolbar.setIcon", "Toggle Icon Action Tool", "Ca30N44V00nn");
          call("ij.Prefs.set", "toggletool.state", "circle");
       } else {
          call("ij.gui.Toolbar.setIcon", "Toggle Icon Action Tool", "C037N44F00nn");
          call("ij.Prefs.set", "toggletool.state", "box");
       }
  }

Thanks. This is cleaner and works for me.
