The actionSelected() signal is now dispatched when the user selects an action from the menu (see the "actions" object). Then the declaration of the MapWidgetContextMenu object in mapwidget.qml can catch that signal in the onActionSelected() slot and obtain the action via switch() branching. The actions enumeration is kept in QML for now, with the idea that specific C++ methods from the mapwidgethelper class will be called directly (if marked as Q_INVOCABLE), instead of a generic onMapAction(action) C++ method in the helper. But if the actions are possible from QML (like copying to clipboard) and are also small and non-expensive, it might be better to keep them in mapwidget.qml. Signed-off-by: Lubomir I.
