Struct winit::dpi::LogicalPosition

source ·
pub struct LogicalPosition<P> {
    pub x: P,
    pub y: P,
}
Expand description

A position represented in logical pixels.

The position is stored as floats, so please be careful. Casting floats to integers truncates the fractional part, which can cause noticable issues. To help with that, an Into<(i32, i32)> implementation is provided which does the rounding for you.
