Provided Methods

unsafe fn numberOfSlideshowItems(&self) -> NSUInteger

where Self: Sized + Message,

return number of items in Slideshow.

unsafe fn slideshowItemAtIndex( &self, index: NSUInteger, ) -> Option<Retained<AnyObject>>

where Self: Sized + Message,

return the item for a given index.

The item can be either: NSImage, NSString, NSURL, CGImageRef, or PDFPage. Note: when using ‘IKSlideshowModeOther’ as slideshowMode, the item has to be a NSURL.

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?

Safety

application_bundle_identifier might not allow None.

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,

Slideshow did change current item index.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
