Struct ScreenSaverView 

#[repr(C)]
pub struct ScreenSaverView { /* private fields */ }

Available on crate features ScreenSaverView and objc2-app-kit only.

An abstract class that defines the interface for subclassers to interact with the screen saver infrastructure.

ScreenSaverView provides the interface for your screen saver, including the content you animate onscreen and an optional configuration sheet. Create your own custom subclass and add it to your screen saver bundle. Use your subclass to create the animations that you want to appear onscreen, and to specify additional animation details.

• Note: When someone previews your screen saver in System Preferences, the system instantiates your ScreenSaverView subclass.

You can draw from your view’s ScreenSaverView/drawRect: method, or you can draw directly from the ScreenSaverView/animateOneFrame method. If you prefer to use the ScreenSaverView/drawRect: method, use the ScreenSaverView/animateOneFrame method to call the <doc ://com.apple.documentation/documentation/appkit/nsview/1483475-setneedsdisplayinrect> method and specify the portions of your view that require updates.

Implementations

impl ScreenSaverView

pub unsafe fn backingStoreType(mtm: MainThreadMarker) -> NSBackingStoreType

Returns the type of backing store you want for your screen saver’s window.

Overview

This method returns <doc ://com.apple.documentation/documentation/appkit/nsbackingstoretype/nsbackingstorebuffered> by default. If you want to change the backing store type, override this method and return a new value. If you override the method, you don’t need to call the inherited version.

pub unsafe fn performGammaFade(mtm: MainThreadMarker) -> bool

Indicates whether to perform a gradual screen fade when the system starts and stops your screen saver’s animation.

Overview

This class method allows the screen saver view to select how the desktop visibly transitions to the screen saver view. When this method returns <doc ://com.apple.documentation/documentation/objectivec/yes>, the screen gradually darkens before the animation begins. When it returns <doc ://com.apple.documentation/documentation/objectivec/no>, the screen transitions immediately to the screen saver. The latter behavior is more appropriate if the screen saver animates a screenshot of the desktop, as is the case for optical lens effects. The default is <doc ://com.apple.documentation/documentation/objectivec/yes>.

pub unsafe fn initWithFrame_isPreview( this: Allocated<Self>, frame: NSRect, is_preview: bool, ) -> Option<Retained<Self>>

Creates a newly allocated screen saver view with the specified frame rectangle and preview information.

Overview

The screen saver application installs the new view object into the view hierarchy of an <doc ://com.apple.documentation/documentation/appkit/nswindow> before the animation begins. This method is the designated initializer for the ScreenSaver/ScreenSaverView class. Returns self.

• Parameters:

• frame: The frame rectangle for the view.

• isPreview: <doc ://com.apple.documentation/documentation/objectivec/yes> if this view provides a preview for system settings, or <doc ://com.apple.documentation/documentation/objectivec/no> if the system fills the screen with your view’s contents.

pub unsafe fn animationTimeInterval(&self) -> NSTimeInterval

The time interval between animation frames.

If your screen saver has particular requirements for time between animation frames, call this method to set the animation rate to a reasonable value.

pub unsafe fn setAnimationTimeInterval( &self, animation_time_interval: NSTimeInterval, )

Setter for animationTimeInterval.

pub unsafe fn startAnimation(&self)

Activates the periodic timer that animates the screen saver.

Overview

The system calls this method when it’s time for you to start animating your screen saver’s content. The system calls this method only once at the start of animations. Use this method to set up any initial state information you require or to allocate expensive resources. If you override this method, you must call the inherited implementation at some point.

See also

• ScreenSaver/ScreenSaverView/stopAnimation

pub unsafe fn stopAnimation(&self)

Deactivates the timer that advances the animation.

Overview

The system calls this method when it’s time for you to stop animating your screen saver’s content. The system calls this method only once at the end of animations. Use this method to unload expensive resources or to reset your screen saver to a known state. If you override this method, you must call the inherited implementation at some point.

See also

• ScreenSaver/ScreenSaverView/startAnimation

pub unsafe fn isAnimating(&self) -> bool

A Boolean value that indicates whether the screen saver is animating.

Overview

The value of this property is <doc ://com.apple.documentation/documentation/objectivec/yes> when the screen saver is animating, and <doc ://com.apple.documentation/documentation/objectivec/no> when it isn’t.

See also

• ScreenSaver/ScreenSaverView/stopAnimation
• ScreenSaver/ScreenSaverView/startAnimation

pub unsafe fn drawRect(&self, rect: NSRect)

Draws the screen saver view.

Overview

ScreenSaver/ScreenSaverView implements ScreenSaver/ScreenSaverView/drawRect: to draw a black background. Subclasses can do their drawing here or in ScreenSaver/ScreenSaverView/animateOneFrame.

See also

• ScreenSaver/ScreenSaverView/stopAnimation
• ScreenSaver/ScreenSaverView/animateOneFrame
• ScreenSaver/ScreenSaverView/startAnimation

pub unsafe fn animateOneFrame(&self)

Advances the screen saver’s animation by a single frame.

Overview

The system calls this method each time the timer animating the screen saver fires. The time between calls to this method is always at least ScreenSaver/ScreenSaverView/animationTimeInterval. The system locks focus on your view before it calls this method, so you can use this method to draw content. You can also let ScreenSaver/ScreenSaverView/drawRect: perform the drawing, in which case you use this method to call <doc ://com.apple.documentation/documentation/appkit/nsview/1483475-setneedsdisplayinrect> to mark your view as dirty. The default implementation of this method does nothing.

See also

• ScreenSaver/ScreenSaverView/drawRect:

pub unsafe fn hasConfigureSheet(&self) -> bool

A Boolean value that indicates whether the screen saver has an associated configuration sheet.

If you provide a configuration sheet in your bundle, override this method and return <doc ://com.apple.documentation/documentation/objectivec/yes>.

See also

• ScreenSaver/ScreenSaverView/configureSheet

pub unsafe fn configureSheet(&self) -> Option<Retained<NSWindow>>

The window that contains the controls to configure the screen saver.

The system runs this window as a sheet, so include buttons that allow the user to end the modal session in which the sheet runs. When the user dismisses the sheet, the controller in charge of the sheet must end the document modal session by calling the <doc ://com.apple.documentation/documentation/appkit/nsapplication> method <doc ://com.apple.documentation/documentation/appkit/nsapplication/1428503-endsheet> with the sheet’s window as the argument.

See also

• ScreenSaver/ScreenSaverView/hasConfigureSheet

pub unsafe fn isPreview(&self) -> bool

A Boolean value that indicates whether the screen saver view is set to a size suitable for previewing its content.

Overview

The system sets the value of this property to <doc ://com.apple.documentation/documentation/objectivec/yes> when it creates a smaller preview of your screen saver. When the value is <doc ://com.apple.documentation/documentation/objectivec/no>, your view matches the size of the screen. Use this property to adjust the content you present. For example, you might change the drawing parameters or data you display in your view.

Methods from Deref<Target = NSObject>

pub fn doesNotRecognizeSelector(&self, sel: Sel) -> !

Handle messages the object doesn’t recognize.

See Apple’s documentation for details.

Methods from Deref<Target = AnyObject>

pub fn class(&self) -> &'static AnyClass

Dynamically find the class of this object.

Panics

May panic if the object is invalid (which may be the case for objects returned from unavailable init/new methods).

Example

Check that an instance of NSObject has the precise class NSObject.

use objc2::ClassType;
use objc2::runtime::NSObject;

let obj = NSObject::new();
assert_eq!(obj.class(), NSObject::class());

pub unsafe fn get_ivar<T>(&self, name: &str) -> &T

where T: Encode,

👎Deprecated: this is difficult to use correctly, use Ivar::load instead.

Use Ivar::load instead.

Safety

The object must have an instance variable with the given name, and it must be of type T.

See Ivar::load_ptr for details surrounding this.

pub fn downcast_ref<T>(&self) -> Option<&T>

where T: DowncastTarget,

Attempt to downcast the object to a class of type T.

This is the reference-variant. Use Retained::downcast if you want to convert a retained object to another type.

Mutable classes

Some classes have immutable and mutable variants, such as NSString and NSMutableString.

When some Objective-C API signature says it gives you an immutable class, it generally expects you to not mutate that, even though it may technically be mutable “under the hood”.

So using this method to convert a NSString to a NSMutableString, while not unsound, is generally frowned upon unless you created the string yourself, or the API explicitly documents the string to be mutable.

See Apple’s documentation on mutability and on isKindOfClass: for more details.

Generic classes

Objective-C generics are called “lightweight generics”, and that’s because they aren’t exposed in the runtime. This makes it impossible to safely downcast to generic collections, so this is disallowed by this method.

You can, however, safely downcast to generic collections where all the type-parameters are AnyObject.

Panics

This works internally by calling isKindOfClass:. That means that the object must have the instance method of that name, and an exception will be thrown (if CoreFoundation is linked) or the process will abort if that is not the case. In the vast majority of cases, you don’t need to worry about this, since both root objects NSObject and NSProxy implement this method.

Examples

Cast an NSString back and forth from NSObject.

use objc2::rc::Retained;
use objc2_foundation::{NSObject, NSString};

let obj: Retained<NSObject> = NSString::new().into_super();
let string = obj.downcast_ref::<NSString>().unwrap();
// Or with `downcast`, if we do not need the object afterwards
let string = obj.downcast::<NSString>().unwrap();

Try (and fail) to cast an NSObject to an NSString.

use objc2_foundation::{NSObject, NSString};

let obj = NSObject::new();
assert!(obj.downcast_ref::<NSString>().is_none());

Try to cast to an array of strings.

use objc2_foundation::{NSArray, NSObject, NSString};

let arr = NSArray::from_retained_slice(&[NSObject::new()]);
// This is invalid and doesn't type check.
let arr = arr.downcast_ref::<NSArray<NSString>>();

This fails to compile, since it would require enumerating over the array to ensure that each element is of the desired type, which is a performance pitfall.

Downcast when processing each element instead.

use objc2_foundation::{NSArray, NSObject, NSString};

let arr = NSArray::from_retained_slice(&[NSObject::new()]);

for elem in arr {
    if let Some(data) = elem.downcast_ref::<NSString>() {
        // handle `data`
    }
}
