17 * @class KToolBarLabelAction ktoolbarlabelaction.h KToolBarLabelAction
18 *
19 * @short Class to display a label in a toolbar.
20 *
21 * KToolBarLabelAction is a convenience class for displaying a label in a
22 * toolbar.
23 *
24 * It provides easy access to the label's #setBuddy(QAction*) and #buddy()
25 * methods and can be used as follows:
26 *
27 * \code
28 *
29 * KHistoryComboBox *findCombo = new KHistoryComboBox(true, this);
30 *
31 * KWidgetAction *action = new KWidgetAction(findCombo, i18n("Find Combo"),
32 * Qt::Key_F6, this, SLOT( slotFocus()),
33 * actionCollection(), "find_combo");
34 *
35 * QAction *action = new KToolBarLabelAction(action, i18n("Find "), "find_label");
36 * action->setShortcut(Qt::Key_F6);
37 * connect(action, &QAction::triggered, this, [this]() { slotFocus(); });
38 *
39 * \endcode
