void | handleAsyncUpdate () override |
Manages the system's stack of modal components.
Normally you'll just use the Component methods to invoke modal states in components, and won't have to deal with this class directly, but this is the singleton object that's used internally to manage the stack.

Creates a ModalComponentManager.
You shouldn't ever call the constructor - it's a singleton, so use ModalComponentManager::getInstance()

Destructor.
int ModalComponentManager::getNumModalComponents | ( | ) | const |
Returns the number of components currently being shown modally.
Returns one of the components being shown modally.
An index of 0 is the most recently-shown, topmost component.
bool ModalComponentManager::isModal | ( | const Component * | component | ) | const |
Returns true if the specified component is in a modal state.
bool ModalComponentManager::isFrontModalComponent | ( | const Component * | component | ) | const |
Returns true if the specified component is currently the topmost modal component.
Adds a new callback that will be called when the specified modal component is dismissed.
If the component is modal, then when it is dismissed, either by being hidden, or by calling Component::exitModalState(), then the Callback::modalStateFinished() method will be called.
Each component can have any number of callbacks associated with it, and this one is added to that list.
The object that is passed in will be deleted by the manager when it's no longer needed. If the given component is not currently modal, the callback object is deleted immediately and no action is taken.
void ModalComponentManager::bringModalComponentsToFront | ( | bool | topOneShouldGrabFocus = true | ) |
Brings any modal components to the front.
bool ModalComponentManager::cancelAllModalComponents | ( | ) |
Calls exitModalState (0) on any components that are currently modal.
int ModalComponentManager::runEventLoopForCurrentComponent | ( | ) |
Runs the event loop until the currently topmost modal component is dismissed, and returns the exit code for that component.
