谢谢fool_leave(请及时结贴) 及时回复。 我的意思不是这种,这种不是标准的文件夹选择对话框,在VC下就有标准的文件夹选择对话框,不知道Java下如何实现。 JFace下是可以实现标准的文件夹选择对话框。代码如下: //Send questions, comments, bug reports, etc. to the authors://Rob Warner ([email protected]) //Robert Harris ([email protected])import org.eclipse.swt.*; import org.eclipse.swt.events.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.widgets.*;/** * This class demonstrates the DirectoryDialog class */ public class ShowDirectoryDialog { /** * Runs the application */ public void run() { Display display = new Display(); Shell shell = new Shell(display); shell.setText("Directory Browser"); createContents(shell); shell.pack(); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) { display.sleep(); } } } /** * Creates the window contents * * @param shell the parent shell */ private void createContents(final Shell shell) { shell.setLayout(new GridLayout(6, true)); new Label(shell, SWT.NONE).setText("Directory:"); // Create the text box extra wide to show long paths final Text text = new Text(shell, SWT.BORDER); GridData data = new GridData(GridData.FILL_HORIZONTAL); data.horizontalSpan = 4; text.setLayoutData(data); // Clicking the button will allow the user // to select a directory Button button = new Button(shell, SWT.PUSH); button.setText("Browse..."); button.addSelectionListener(new SelectionAdapter() { public void widgetSelected(SelectionEvent event) { DirectoryDialog dlg = new DirectoryDialog(shell); // Set the initial filter path according // to anything they've selected or typed in dlg.setFilterPath(text.getText()); // Change the title bar text dlg.setText("SWT's DirectoryDialog"); // Customizable message displayed in the dialog dlg.setMessage("Select a directory"); // Calling open() will open and run the dialog. // It will return the selected directory, or // null if user cancels String dir = dlg.open(); if (dir != null) { // Set the text box to the new selection text.setText(dir); } } }); } /** * The application entry point * * @param args the command line arguments */ public static void main(String[] args) { new ShowDirectoryDialog().run(); } }但是用Swing库怎么实现呢?
f.setVisible(true);
JFileChooser c=new JFileChooser();
c.setFileSelectionMode(JFileChooser.DIRECTORIES_ONLY);
c.showSaveDialog(f);

除非你自己用Swing组件拼装
