Struct SystemMouseCursor 

pub struct SystemMouseCursor { /* private fields */ }

A mouse cursor that is natively supported on the platform that the application is running on.

System cursors can be used without external resources, and their appearances match the experience of native apps. Examples of system cursors are a pointing arrow, a pointing hand, a double arrow for resizing, or a text I-beam, etc.

An instance of SystemMouseCursor refers to one cursor from each platform that represents the same concept, such as being text, being clickable, or being a forbidden operation. Since the set of system cursors supported by each platform varies, multiple instances can correspond to the same system cursor.

Each cursor is noted with its corresponding native cursors on each platform:

• Android: API name in Java
• Web: CSS cursor
• Windows: Win32 API
• Linux: GDK, gdk_cursor_new_from_name
• macOS: API name in ObjectiveC

If the platform that the application is running on is not listed for a cursor, using this cursor falls back to SystemMouseCursors::BASIC.

SystemMouseCursors enumerates the complete set of system cursors supported by Flutter, which are hard-coded in the engine. Therefore, manually instantiating this class is not supported.

Implementations

impl SystemMouseCursor

pub fn kind(&self) -> SystemMouseCursorKind

The kind of the cursor.

The interpretation of kind is platform-dependent.

Trait Implementations

Formats the value using the given formatter.

impl Eq for SystemMouseCursor

impl From<SystemMouseCursor> for MouseCursorRef

fn from(cursor: SystemMouseCursor) -> MouseCursorRef

Converts to this type from the input type.

impl Hash for SystemMouseCursor
