Possible to set default directory

[Jon Harman-3]

Hi,
When my plugin is executed from a command line sometimes the default
directory gets incorrectly set (to c:\windows).
So far I have not not figured out what is going on, but a possible fix
would be to set that default directory to be the directory of the image
opened in my plugin.  Any way to do that?  I don't see any way in the
ImageJ open code.

Hi Jon,

ij.io.OpenDialog has a method
  public OpenDialog(String title, String defaultDir, String defaultName)

where you can set the default directory. If you use some other way of
opening the file, you can use the OpenDialog method
  public static void setDefaultDirectory(String defaultDir)

to set the default directory.

You can get the directory of an image via the ImagePlus method
  String dir = imp.getOriginalFileInfo().directory;
Note that the directory many be null (if the image was not read from disk).

Thanks Michael.

My knowledge of Java is minimal.  I don't see how to use
setDefaultDirectory() without an OpenDialog.

I now do this:

FileInfo fi = imp.getOriginalFileInfo();
if(fi.directory != null) {
        OpenDialog defdia = new OpenDialog("",fi.directory);
        }

Hello Jon,

I recently also had problems with OpenDialog that might be related to yours. Calls to OpenDialog.setDefaultDirectory() had no effect, i.e., they left the default directory unchanged. I had no time to investigate further but noticed that, e.g., after calling

   OpenDialog.setDefaultDirectory("/");

the result from OpenDialog.getDefaultDirectory() was the path "/\". Looking at the source code this is due to the instruction (http://rsbweb.nih.gov/ij/developer/source/ij/io/OpenDialog.java.html)

   defaultDirectory = defaultDirectory + File.separator;

at the end of the setDefaultDirectory method (and "\" being the default file separator in Windows). I am not sure the problem shows in non-Windows environments at all.

In any event, the problem mysteriously disappeared when I set the "Use JFileChooser to open/save" in the Input/Output... options. This might explain why the problem appears inconsistently and I still suspect there is a bug in the setDefaultDirectory method.

Hope this helps,
Wilhelm

Hi Jon,

your code is absolutely fine (I guess that you have an 'else' branch for
the case that fi.directory == null).

By the way, OpenDialog.setDefaultDirectory is a static method, so you can
set it without having a particular instance of OpenDialog, just use the
class name as a prefix:

  OpenDialog.setDefaultDirectory(myDefaultDirectory);

The String argument (here 'myDefaultDirectory') may have a path separator
(backslash for Windows, otherwise slash) at the end.

You need the static method if the OpenDialog is no called by your code but
rather by some other command, so you have no access to the instance of
OpenDialog.
