Implementations

impl NSToolbar

pub unsafe fn initWithIdentifier( this: Allocated<Self>, identifier: &NSToolbarIdentifier, ) -> Retained<Self>

The identifier is used to form the toolbar’s autosave name. Toolbars with the same identifier are implicitly synchronized so that they maintain the same state.

pub unsafe fn init(this: Allocated<Self>) -> Retained<Self>

Calls through to -initWithIdentifier: with an empty string identifier. Customizable toolbars should use -initWithIdentifier: with a unique identifier instead.

pub unsafe fn insertItemWithItemIdentifier_atIndex( &self, item_identifier: &NSToolbarItemIdentifier, index: NSInteger, )

Inserts an item with the specified identifier in the receiving toolbar at the specified index.

Any change made will be propagated immediately to all other toolbars with the same identifier.

pub unsafe fn removeItemAtIndex(&self, index: NSInteger)

Removes the item at the specified index in the receiving toolbar.

Any change made will be propagated immediately to all other toolbars with the same identifier.

pub unsafe fn removeItemWithItemIdentifier( &self, item_identifier: &NSToolbarItemIdentifier, )

Removes the item with matching itemIdentifier in the receiving toolbar. If multiple items share the same identifier (as is the case with space items) all matching items will be removed. To remove only a single space item, use -removeItemAtIndex: instead.

Any change made will be propagated immediately to all other toolbars with the same identifier.

pub unsafe fn delegate( &self, ) -> Option<Retained<ProtocolObject<dyn NSToolbarDelegate>>>

Customizable toolbars must have a delegate, and must implement the required NSToolbarDelegate methods.

pub unsafe fn setDelegate( &self, delegate: Option<&ProtocolObject<dyn NSToolbarDelegate>>, )

This is a weak property. Setter for delegate.

pub unsafe fn isVisible(&self) -> bool

Toggles the visibility of the toolbar. This property may be modified by the user in toolbars with allowsUserCustomization enabled. This property is key value observable on macOS 14.0 and higher.

pub unsafe fn setVisible(&self, visible: bool)

Setter for isVisible.

pub unsafe fn runCustomizationPalette(&self, sender: Option<&AnyObject>)

Customizable toolbars (those with delegates) can show a palette which allows users to populate the toolbar with individual items or to reset the toolbar to some default set of items. The items and item sets in the palette are specified by the delegate (-toolbarAllowedItemIdentifiers: and -toolbarDefaultItemIdentifiers:). When the user is done configuring, they will dismiss the palette.

pub unsafe fn customizationPaletteIsRunning(&self) -> bool

Whether or not the customization palette is currently running. On macOS 15.0 and above this property is key value observable.

pub unsafe fn displayMode(&self) -> NSToolbarDisplayMode

The current display mode of items in the toolbar. In toolbars with allowsDisplayModeCustomization enabled this is a user modifiable property. This property is key value observable.

pub unsafe fn setDisplayMode(&self, display_mode: NSToolbarDisplayMode)

Setter for displayMode.

pub unsafe fn selectedItemIdentifier( &self, ) -> Option<Retained<NSToolbarItemIdentifier>>

Sets the toolbar’s selected item by identifier. Use this to force an item identifier to be selected. Toolbar manages selection of image items automatically. This method can be used to select identifiers of custom view items, or to force a selection change. See -toolbarSelectableItemIdentifiers: delegate method for more details. This property is key value observable.

pub unsafe fn setSelectedItemIdentifier( &self, selected_item_identifier: Option<&NSToolbarItemIdentifier>, )

Setter for selectedItemIdentifier.

pub unsafe fn allowsUserCustomization(&self) -> bool

This flag controls whether or not users can configure the toolbar by dragging items around, and whether or not the customization palette can be used. The default value is NO, but can be changed at any time. For instance, a developer may not want users to be able to edit the toolbar while some event is being processed.

pub unsafe fn setAllowsUserCustomization(&self, allows_user_customization: bool)

Setter for allowsUserCustomization.

pub unsafe fn allowsDisplayModeCustomization(&self) -> bool

Whether or not the user is allowed to change display modes at run time. This functionality is independent of customizing the order of the items themselves. Only disable when the functionality or legibility of your toolbar could not be improved by another display mode. The user’s selection will be persisted using the toolbar’s identifier when autosavesConfiguration is enabled. The default is YES for apps linked on macOS 15.0 and above.

pub unsafe fn setAllowsDisplayModeCustomization( &self, allows_display_mode_customization: bool, )

Setter for allowsDisplayModeCustomization.

pub unsafe fn identifier(&self) -> Retained<NSToolbarIdentifier>

All toolbars with the same name will share the same display attributes, and item order. If a toolbar autosaves its configuration, the item identifier will be used as the autosave name.

pub unsafe fn items(&self) -> Retained<NSArray<NSToolbarItem>>

Available on crate feature NSToolbarItem only.

Allows you to access all current items in the toolbar.

pub unsafe fn visibleItems(&self) -> Option<Retained<NSArray<NSToolbarItem>>>

Available on crate feature NSToolbarItem only.

Allows you to access the current visible items (non clipped).

pub unsafe fn itemIdentifiers( &self, ) -> Retained<NSArray<NSToolbarItemIdentifier>>

An array of itemIdentifiers that represent the current items in the toolbar. Setting this property will set the current items in the toolbar by diffing against items that already exist. Use this with great caution if allowsUserCustomization is enabled as it will override any customizations the user has made. This property is key value observable.

pub unsafe fn setItemIdentifiers( &self, item_identifiers: &NSArray<NSToolbarItemIdentifier>, )

Setter for itemIdentifiers.

pub unsafe fn centeredItemIdentifiers( &self, ) -> Retained<NSSet<NSToolbarItemIdentifier>>

Items with centered identifiers will be centered together in the Toolbar relative to the window assuming space allows. The order of items is initially defined by the default set of identifiers, but may be customized by the user. Centered items may not be moved outside of the center set of items by the user. This property is archived.

pub unsafe fn setCenteredItemIdentifiers( &self, centered_item_identifiers: &NSSet<NSToolbarItemIdentifier>, )

Setter for centeredItemIdentifiers.

pub unsafe fn autosavesConfiguration(&self) -> bool

If autosavesConfiguration is YES, the toolbar will automatically write changes the user makes to user defaults. Customizable toolbars will want to set this flag to YES. Setting this to NO means changes in configuration are not written automatically, however you can use the configurationDictionary method to do it yourself. Default is NO.

pub unsafe fn setAutosavesConfiguration(&self, autosaves_configuration: bool)

Setter for autosavesConfiguration.

pub unsafe fn validateVisibleItems(&self)

Typically you should not invoke this method. This method is called on window updates with the purpose of validating each of the visible items. The toolbar will iterate through the list of visible items, sending each a -validate message. If this method is invoked directly, all visible items including those with autovalidates disabled will get a -validate message.

pub unsafe fn allowsExtensionItems(&self) -> bool

When YES, the receiver can dynamically create toolbar items for Action extensions in the toolbar configuration panel. To be included, an extension needs to declare NSExtensionServiceAllowsToolbarItem=YES in its Info.plist. The default value is NO.

pub unsafe fn setAllowsExtensionItems(&self, allows_extension_items: bool)

Setter for allowsExtensionItems.

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

Available on crate feature NSAccessibilityConstants only.

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.

Available on crate feature NSAccessibilityConstants only.

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,

Available on crate feature NSAccessibilityConstants only.

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`
    }
}
