Create a FileFilter using Java
Post date: Mar 29, 2011 5:12:42 AM
Create a FileFilter Class:
import java.io.File;
import javax.swing.filechooser.FileFilter;
public class IconImageFilter extends FileFilter {
//Accept all directories and all gif, jpg, tiff, or png files.
public boolean accept(File f) {
if (f.isDirectory()) {
return true;
}
String extension = Utils.getExtension(f);
if (extension != null) {
if (extension.equals(Utils.tiff) ||
extension.equals(Utils.tif) ||
extension.equals(Utils.gif) ||
extension.equals(Utils.jpeg) ||
extension.equals(Utils.jpg) ||
extension.equals(Utils.png)) {
return true;
} else {
return false;
}
}
return false;
}
//The description of this filter
public String getDescription() {
return "Icon Images";
}
}
Once you create this class, then you need to add it into the JFileChooser by using following code
JFileChooser fileChooser = new JFileChooser();
fileChooser.setFileFilter(new IconImageFilter());
//Disable to choosing the All the file option
fileChooser.setAcceptAllFileFilterUsed(false);
int returnValue=0;
//For select the project file
int selectValue=JFileChooser.APPROVE_OPTION;
while(selectValue== JFileChooser.APPROVE_OPTION){
returnValue = fileChooser.showOpenDialog(this);
//Return 1 if file is selected
if(returnValue == JFileChooser.APPROVE_OPTION){
//Get the selected file
selectedFile = fileChooser.getSelectedFile();
//Set the path into the text box
System.out.println(selectedFile.getPath()); break;
}
else{
//Selected wrong file
selectValue=JOptionPane.showConfirmDialog(this, "Please Select JAR, WAR,JAVA or ZIP files!","Oops Wrong File!",JOptionPane.OK_OPTION,JOptionPane.ERROR_MESSAGE);
}
}
