Methods to implement by any object in the responder chain to control the Preview Panel

QLPreviewPanel shows previews for items provided by the first object in the responder chain accepting to control it. You generally implement these methods in your window controller or delegate. You should never try to modify Preview panel state if you’re not controlling the panel.

Provided Methods

unsafe fn acceptsPreviewPanelControl( &self, panel: Option<&QLPreviewPanel>, ) -> bool

Available on crate feature objc2-app-kit only.

Sent to each object in the responder chain to find a controller.

Parameter panel: The Preview Panel looking for a controller.

Returns: YES if the receiver accepts to control the panel. You should never call this method directly.

Safety

panel might not allow None.

unsafe fn beginPreviewPanelControl(&self, panel: Option<&QLPreviewPanel>)

Available on crate feature objc2-app-kit only.

Sent to the object taking control of the Preview Panel.

Parameter panel: The Preview Panel the receiver will control.

The receiver should setup the preview panel (data source, delegate, binding, etc.) here. You should never call this method directly.

Safety

panel might not allow None.

unsafe fn endPreviewPanelControl(&self, panel: Option<&QLPreviewPanel>)

Available on crate feature objc2-app-kit only.

Sent to the object in control of the Preview Panel just before stopping its control.

Parameter panel: The Preview Panel that the receiver will stop controlling.

The receiver should unsetup the preview panel (data source, delegate, binding, etc.) here. You should never call this method directly.

Safety

panel might not allow None.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
