Trait MouseRelativeEvent

Source 
pub trait MouseRelativeEvent: Sized {
    // Required methods
    fn from_pos(x: [f64; 2], old_event: &Self) -> Option<Self>;
    fn mouse_relative<U, F>(&self, f: F) -> Option<U>
       where F: FnMut([f64; 2]) -> U;

    // Provided method
    fn mouse_relative_args(&self) -> Option<[f64; 2]> { ... }
}
Expand description

The relative movement of mouse cursor.

These events might be emitted even the cursor is captured by the window.

Required Methods§

Source

fn from_pos(x: [f64; 2], old_event: &Self) -> Option<Self>

Creates a mouse relative event.

Preserves time stamp from original input event, if any.

Source

fn mouse_relative<U, F>(&self, f: F) -> Option<U>
where F: FnMut([f64; 2]) -> U,

Calls closure if this is a mouse relative event.

Provided Methods§

Source

fn mouse_relative_args(&self) -> Option<[f64; 2]>

Returns mouse relative arguments.

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.
