Hi Joachim,

as far as I can say, ImageJ OpenDialog does not support it.

java.awt.FileDialog has a setFilenameFilter method. There, you can  
check for, e.g., endsWith(".jpg") etc. I think that you can't modify  
the filter while the dialog box is open.
For a user-defined filter, you need the javax.swing.JFileChooser.


The downside of using java.awt.FileDialog or  
javax.swing.JFileChooser: no interfacing to the ImageJ macro langage  
unless you add code for it yourself. Also, the ImageJ default  
directory is not set.
