[news.eclipse.platform.swt] Wrapping Label

[Matt Dickie <matt@xxxxxxxxxx>]

Hi all,

I have a Dialog (a subclass of ElementTreeSelectionDialog) where I have 
a message which is too large for a single line (its content is dynamic 
and includes an arbitrary path).

To get the label to wrap I had to override the method createMessageArea 
(from the superclass SelectionDialog) as below. Wrapping works, but the 
label is not wrapped when the dialog is first shown, instead the dialog 
is elongated to show the entire label. How can I fix this, as it looks 
bad? I have tried setting the widthHint of the GridData, but this seems 
to set a maximum width for the label which it will not grow beyond even 
when the dialog is resized to be larger.

Thanks in advance.

Overridden createMessageArea method:

  /* (non-Javadoc)
   * @see 
org.eclipse.ui.dialogs.SelectionDialog#createMessageArea(org.eclipse.swt.widgets.Composite)
   */
  @Override
  protected Label createMessageArea(Composite composite) {
    Label label = new Label(composite, SWT.WRAP);
    String message = getMessage();
    if (message != null) {
      label.setText(message);
    }
    label.setFont(composite.getFont());
    GridData gd = new GridData(SWT.LEAD, SWT.CENTER, true, false);
    label.setLayoutData(gd);
    return label;
  }
