pub trait ICursorFactory {
// Required method
fn get_cursor(&self, cursor_type: StandardCursorType) -> Rc<dyn ICursorImpl>;
// Provided method
fn create_cursor(
&self,
cursor: &Bitmap,
hot_spot: PixelPoint,
) -> Rc<dyn ICursorImpl> { ... }
}Expand description
Creates the platform implementations of mouse cursors.
This is an implementation detail of the platform backends.
Required Methods§
Sourcefn get_cursor(&self, cursor_type: StandardCursorType) -> Rc<dyn ICursorImpl>
fn get_cursor(&self, cursor_type: StandardCursorType) -> Rc<dyn ICursorImpl>
Gets the platform cursor for a standard cursor type.
Provided Methods§
Sourcefn create_cursor(
&self,
cursor: &Bitmap,
hot_spot: PixelPoint,
) -> Rc<dyn ICursorImpl>
fn create_cursor( &self, cursor: &Bitmap, hot_spot: PixelPoint, ) -> Rc<dyn ICursorImpl>
Creates a platform cursor from a bitmap. hot_spot is the position
within the bitmap that is the position of the pointer.
Every backend is expected to implement this. The default exists so that a backend written before bitmap cursors were part of the contract keeps building.
§Panics
The default implementation panics: the backend does not support bitmap cursors.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
