SWT File Browser

This section illustrates you how to browse a file.

In SWT, the class FileDialog allow the user to navigate the file system and select a file name. In order to layout the text, we have used the method text.setLayoutData(data). The method file.isFile() tests whether the file denoted by the pathname is a normal file. The method file.list() returns an array of files and directories. The method text.setText(files[i]) sets the selected file in the text. The method text.setEditable(true) sets the editable state.

Here is the code of FileBrowser.java


import java.io.File;

import org.eclipse.swt.SWT;

import org.eclipse.swt.events.*;

import org.eclipse.swt.layout.*;

import org.eclipse.swt.widgets.*;



public class FileBrowser {

  Display display = new Display();

  Shell shell = new Shell(display);

  Text text;



  public FileBrowser() {

  init();

  shell.pack();

  shell.setSize(350,60);

  shell.open();

 

  while (!shell.isDisposed()) {

  if (!display.readAndDispatch()) {

  display.sleep();

  }

  }

  display.dispose();

  }

  private void init() {

  shell.setText("File Browser");

  shell.setLayout(new GridLayout(2, true));

  GridData data = new GridData(GridData.FILL_BOTH);



  text = new Text(shell, SWT.NONE);

  text.setLayoutData(data);

  

  Button button = new Button(shell, SWT.PUSH);

  button.setText("Browse");

  button.addSelectionListener(new SelectionAdapter() {

  public void widgetSelected(SelectionEvent e) {

  FileDialog dialog = new FileDialog(shell, SWT.NULL);

  String path = dialog.open();

  if (path != null) {



  File file = new File(path);

  if (file.isFile())

  displayFiles(new String[] { file.toString()});

  else

  displayFiles(file.list());



  }

  }

  });  

  }

 public void displayFiles(String[] files) {

  for (int i = 0; files != null && i < files.length; i++) {

  text.setText(files[i]);

  text.setEditable(true);

  }

}

 public static void main(String[] args) {

  new FileBrowser();

  }

}
