Member Function Documentation

◆ menuItemsChanged()

void MenuBarModel::menuItemsChanged ( )

Call this when some of your menu items have changed.

This method will cause a callback to any MenuBarListener objects that are registered with this model.

If this model is displaying items from an ApplicationCommandManager, you can use the setApplicationCommandManagerToWatch() method to cause change messages to be sent automatically when the ApplicationCommandManager is changed.

addListener, removeListener, MenuBarListener

◆ setApplicationCommandManagerToWatch()

void MenuBarModel::setApplicationCommandManagerToWatch ( ApplicationCommandManager * manager)

Tells the menu bar to listen to the specified command manager, and to update itself when the commands change.

This will also allow it to flash a menu name when a command from that menu is invoked using a keystroke.

◆ addListener()

void MenuBarModel::addListener ( Listener * listenerToAdd)

Registers a listener for callbacks when the menu items in this model change.

The listener object will get callbacks when this object's menuItemsChanged() method is called.

removeListener

◆ removeListener()

void MenuBarModel::removeListener ( Listener * listenerToRemove)

Removes a listener.

See also
addListener

◆ getMenuBarNames()

virtual StringArray MenuBarModel::getMenuBarNames ( )
pure virtual

This method must return a list of the names of the menus.

◆ getMenuForIndex()

virtual PopupMenu MenuBarModel::getMenuForIndex ( int topLevelMenuIndex,
const String & menuName )
pure virtual

This should return the popup menu to display for a given top-level menu.

Parameters
topLevelMenuIndexthe index of the top-level menu to show
menuNamethe name of the top-level menu item to show

◆ menuItemSelected()

virtual void MenuBarModel::menuItemSelected ( int menuItemID,
int topLevelMenuIndex )
pure virtual

This is called when a menu item has been clicked on.

Parameters
menuItemIDthe item ID of the PopupMenu item that was selected
topLevelMenuIndexthe index of the top-level menu from which the item was chosen (just in case you've used duplicate ID numbers on more than one of the popup menus)

◆ menuBarActivated()

virtual void MenuBarModel::menuBarActivated ( bool isActive)
virtual

This is called when the user starts/stops navigating the menu bar.

Parameters
isActivetrue when the user starts navigating the menu bar

◆ setMacMainMenu()

static void MenuBarModel::setMacMainMenu ( MenuBarModel * newMenuBarModel,
const PopupMenu * extraAppleMenuItems = nullptr,
const String & recentItemsMenuName = String() )
static

OSX ONLY - Sets the model that is currently being shown as the main menu bar at the top of the screen on the Mac.

You can pass nullptr to stop the current model being displayed. Be careful not to delete a model while it is being used.

An optional extra menu can be specified, containing items to add to the top of the apple menu. (Confusingly, the 'apple' menu isn't the one with a picture of an apple, it's the one next to it, with your application's name at the top and the services menu etc on it). When one of these items is selected, the menu bar model will be used to invoke it, and in the menuItemSelected() callback the topLevelMenuIndex parameter will be -1. If you pass in an extraAppleMenuItems object then newMenuBarModel must be non-null.

If the recentItemsMenuName parameter is non-empty, then any sub-menus with this name will be replaced by OSX's special recent-files menu.

◆ getMacMainMenu()

static MenuBarModel * MenuBarModel::getMacMainMenu ( )
static

OSX ONLY - Returns the menu model that is currently being shown as the main menu bar.

◆ getMacExtraAppleItemsMenu()

static const PopupMenu * MenuBarModel::getMacExtraAppleItemsMenu ( )
static

OSX ONLY - Returns the menu that was last passed as the extraAppleMenuItems argument to setMacMainMenu(), or nullptr if none was specified.

◆ applicationCommandInvoked()

void MenuBarModel::applicationCommandInvoked ( const ApplicationCommandTarget::InvocationInfo & )
overridevirtual

Called when an app command is about to be invoked.

Implements ApplicationCommandManagerListener.

◆ applicationCommandListChanged()

void MenuBarModel::applicationCommandListChanged ( )
overridevirtual

Called when commands are registered or deregistered from the command manager, or when commands are made active or inactive.

Note that if you're using this to watch for changes to whether a command is disabled, you'll need to make sure that ApplicationCommandManager::commandStatusChanged() is called whenever the status of your command might have changed.

Implements ApplicationCommandManagerListener.

◆ handleAsyncUpdate()

void MenuBarModel::handleAsyncUpdate ( )
overridevirtual

Called back to do whatever your class needs to do.

This method is called by the message thread at the next convenient time after the triggerAsyncUpdate() method has been called.

Implements AsyncUpdater.

◆ handleMenuBarActivate()

void MenuBarModel::handleMenuBarActivate ( bool isActive)
