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