public final WorkbenchDialogBuilder blocking(boolean blocking) {
      this.blocking = blocking;
      return this;
    }
Defines whether the dialog is blocking (modal) or not.

@param blocking If false (non-blocking), clicking outside of the {@code dialog} will cause it
                to get hidden, together with its {@link GlassPane}. If true (blocking),
                clicking outside of the {@code dialog} will not do anything. In this case,
                the {@code dialog} must be closed by pressing one of the buttons.
@return builder for chaining
