WizTools.org FileChooser Abstraction Library

An abstraction library (adapter pattern) to easily switch between JFileChooser and FileDialog.

Usage

Typical usage:

import org.wiztools.filechooser.*;

...

FileChooser fc = new JFCFileChooser(); // To use JFileChooser
FileChooser fc = new FDFileChooser();  // To use FileDialog

...

fc.setDialogTitle("JFileChooser");
FileChooserResponse res = fc.showOpenDialog(this); // `this' could be Frame / Dialog
if(res == FileChooserResponse.APPROVE_OPTION) {
	File f = fc.getSelectedFile();
	// your code
}
else if(res == FileChooserResponse.CANCEL_OPTION) {
	// your code
}

Using FileFilter:

import org.wiztools.filechooser.*;

...

// 1. Define FileChooser:
FileChooser fc = ...;


// 2. Define FileFilter:
FileFilter ff = new FileFilter() {
	public boolean accept(File file) {
		if(file.getName().endsWith(".xml")) {
			return true;
		}
		return false;
	}

	public String getDescription() {
		return "XML";
	}
};

// 3. Assign the FileFilter to the FileChooser:
fc.setFileFilter(ff);

Why?

JFileChooser is the preferred way of doing things in Java. But, if you want to comply to Apple Sandbox requirements when on-boarding your app to Mac App Store, you must use FileDialog instead of JFileChooser (FileDialog uses NSOpenDialog and NSSaveDialog internally).

This library may be used to:

1. Modify your app to use FileDialog with minimal code change.
2. Support FileDialog in Mac platform, and JFileChooser in other platforms, with very less code specific to each platform.
