[SOLVED] JFileChooser question; setting the default 'file filter'

Wim Sturkenboom · 09-28-2010, 03:36 AM

Code:

        // create a filechooser;
        JFileChooser chooser = new JFileChooser(cwd);
        FileNameExtensionFilter filter = new FileNameExtensionFilter(
            "sdf files (*.sdf)", "sdf");
        chooser.setFileFilter(filter);
        // the last one added seems to be the default
        filter = new FileNameExtensionFilter(
            "xml files (*.xml)", "xml");
        chooser.setFileFilter(filter);
        chooser.setDialogTitle("Open schedule file");

This will give 3 filefilters ('all files', 'sdf files' and 'xml files') for a fileopen dialog.
Exactly as I want (in alphanumerical order), but XML is the default extension and I like SDF to be the default extension.

Research has not revealed solutions; the setFileFilter method sets the primary filter. If I swap the sequence in the code, SDF becomes the default (as I want) but the sequence is wrong (All, XML, SDF).

Anybody any pointers how to solve this?

Code:

        // create a filechooser;
        JFileChooser chooser = new JFileChooser(cwd);

        // create filters
        FileNameExtensionFilter sdfFilter = new FileNameExtensionFilter(
            "sdf files (*.sdf)", "sdf");
        FileNameExtensionFilter xmlFilter = new FileNameExtensionFilter(
            "xml files (*.xml)", "xml");

        // add filters
        chooser.addChoosableFileFilter(sdfFilter);
        chooser.addChoosableFileFilter(xmlFilter);

        // set selected filter
        chooser.setFileFilter(sdfFilter);

Thanks a million, indeed works.

Why can't I find that myself; went through the JFileChooser's methods 10s of times
