 /**
  * @brief An action which when triggered will open a NewStuff.Dialog or a NewStuff.Page, depending on settings
  *
  * This component is equivalent to the old Button component, but functions in more modern applications
  *
  * The following is a simple example of how to use this Action to show wallpapers from the KDE Store, on a
  * system where Plasma has been installed (and consequently the wallpaper knsrc file is available). This also
  * shows how to make the action push a page to a pageStack rather than opening a dialog:
  *
 \code{.qml}
 import org.kde.newstuff as NewStuff
 
 NewStuff.Action {
     configFile: "wallpaper.knsrc"
     text: i18n("&Get New Wallpapers…")
     pageStack: applicationWindow().pageStack
     onEntryEvent: function(entry, event) {
         if (event === NewStuff.Entry.StatusChangedEvent) {
             // A entry was installed, updated or removed
         } else if (event === NewStuff.Entry.AdoptedEvent) {
             // The "AdoptionCommand" from the knsrc file was run for the given entry.
             // This should not require refreshing the data for the model
         }
     }
 }
 \endcode
  *
  * @see NewStuff.Button
  * @since 5.81
