1、显示一个简单的保存对话框。
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
shell.open ();
FileDialog dialog = new FileDialog (shell, SWT.SAVE);
dialog.setFilterNames (new String [] {"Batch Files", "All Files (*.*)"});
dialog.setFilterExtensions (new String [] {"*.bat", "*.*"}); //Windows wild cards
dialog.setFilterPath ("c:\\"); //Windows path
dialog.setFileName ("fred.bat");
System.out.println ("Save to: " + dialog.open ()); //打开对话框
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}
