 * @short Class to display a label in a toolbar.

 * TDEToolBarLabelAction is a convenience class for displaying a label in a

 * methods and can be used as follows:
 *
 * \code
 *
 * KHistoryCombo* findCombo = new KHistoryCombo(true, this);
 * KWidgetAction* action
 *   = new KWidgetAction(findCombo, i18n("F&ind Combo"), TQt::Key_F6, this,
 *                       TQ_SLOT(slotFocus()), actionCollection(), "find_combo");
 *
 * new TDEToolBarLabelAction(findCombo, i18n("F&ind "), 0, this,
 *                         TQ_SLOT(slotFocus()), actionCollection(),
 *             "find_label");
 *
 * \endcode
