Provided Methods

unsafe fn numberOfSlideshowItems(&self) -> NSUInteger

where Self: Sized + Message,

return number of items in Slideshow.

unsafe fn nameOfSlideshowItemAtIndex( &self, index: NSUInteger, ) -> Option<Retained<NSString>>

where Self: Sized + Message,

Display name for item at index.

unsafe fn canExportSlideshowItemAtIndex_toApplication( &self, index: NSUInteger, application_bundle_identifier: Option<&NSString>, ) -> bool

where Self: Sized + Message,

should the export button be enabled for a given item at index?

unsafe fn slideshowWillStart(&self)

where Self: Sized + Message,

Slideshow will start.

unsafe fn slideshowDidStop(&self)

where Self: Sized + Message,

Slideshow did stop.

unsafe fn slideshowDidChangeCurrentIndex(&self, new_index: NSUInteger)

where Self: Sized + Message,
