How to change the "default folder"?

[Norbert Vischer-2]

When opening or saving a file via Java, I want to present a file dialog that displays a desired directory that the user most probably will choose as destination.
However, I don't know how to influence the OS - it usually makes its own decisions and presents a completely different "default folder".
(On the Mac, I couldn't solve this problem since many years) - Any ideas?

With ij.io.OpenDialog, use the
OpenDialog.setDefaultDirectory("/path/to/some/dir");

See http://rsb.info.nih.gov/ij/developer/api/ij/io/OpenDialog.html

You can also use the other constructor which even takes a default name
(which can be null as far as I can tell):

http://pacific/javadoc/ij/io/OpenDialog.html#OpenDialog(java.lang.String,%20java.lang.String,%20java.lang.String)

Ciao,

The other constructor takes a default directory and a default name,
but if both are not null, the file is directly opened without the
dialog being ever shown. At least that was the case a few ImageJ
versions ago, when invoked within the "run" method of a PlugIn that is
then run from the menus. I haven't tested recently.
