TabItem handling

[nocomm]

Hi there!

First of all I have to say that I really like your tool - it makes it even more fun, programming with Eclipse, now!

My question concerns the TabItem handling:
In my application I use a TabFolder, where on the first Tab the user is asked to login. At this moment the other TabItems should not be accessible! I already read in another post, that it is not possible yet to disable a TabItem, so my idea was, to catch the users mouseclick on another TabItem and to disallow the access somehow (does not really matter how). But the problem is, that I did not find any method that helps me to get the event when the selected TabItem changes!

Am I blind? Is there a way to recognize this?

Thanx

Here is small code that does what you want.

Code: Select all

   private static Text m_UserText;
   private static TabItem m_InfoTabItem;
   private static TabItem m_LoginTabItem;
   public static void main(String[] args) {
      final Display display = new Display();
      final Shell shell = new Shell();
      shell.setLayout(new FillLayout());
      shell.setText("SWT Application");
      {
         final TabFolder tabFolder = new TabFolder(shell, SWT.NONE);
         tabFolder.addSelectionListener(new SelectionAdapter() {
            public void widgetSelected(SelectionEvent e) {
               if ((e.item != m_LoginTabItem) && (m_UserText != null) && (m_UserText.getText().length() == 0)) {
                  tabFolder.setSelection(0);
               }
            }
         });
         {
            m_LoginTabItem = new TabItem(tabFolder, SWT.NONE);
            m_LoginTabItem.setText("Login");
            {
               final Composite composite = new Composite(tabFolder, SWT.NONE);
               final GridLayout gridLayout = new GridLayout();
               gridLayout.numColumns = 2;
               composite.setLayout(gridLayout);
               m_LoginTabItem.setControl(composite);
               {
                  final Label label = new Label(composite, SWT.NONE);
                  label.setText("User:");
               }
               {
                  m_UserText = new Text(composite, SWT.BORDER);
                  m_UserText.setLayoutData(new GridData(GridData.FILL_HORIZONTAL));
               }
            }
         }
         {
            m_InfoTabItem = new TabItem(tabFolder, SWT.NONE);
            m_InfoTabItem.setText("Information");
         }
      }
      // DESIGNER: Add controls before this line.
      shell.open();
      while (!shell.isDisposed()) {
         if (!display.readAndDispatch())
            display.sleep();
      }
   }
