Struct winit::monitor::MonitorHandle
source · [−]pub struct MonitorHandle { /* private fields */ }
Expand description
Handle to a monitor.
Allows you to retrieve information about a given monitor and can be used in Window
creation.
Implementations
sourceimpl MonitorHandle
impl MonitorHandle
sourcepub fn name(&self) -> Option<String>
pub fn name(&self) -> Option<String>
Returns a human-readable name of the monitor.
Returns None
if the monitor doesn’t exist anymore.
Platform-specific
- Web: Always returns None
sourcepub fn size(&self) -> PhysicalSize<u32>
pub fn size(&self) -> PhysicalSize<u32>
sourcepub fn position(&self) -> PhysicalPosition<i32>
pub fn position(&self) -> PhysicalPosition<i32>
Returns the top-left corner position of the monitor relative to the larger full screen area.
Platform-specific
- Web: Always returns (0,0)
sourcepub fn refresh_rate_millihertz(&self) -> Option<u32>
pub fn refresh_rate_millihertz(&self) -> Option<u32>
The monitor refresh rate used by the system.
When using exclusive fullscreen, the refresh rate of the VideoMode
that was used to
enter fullscreen should be used instead.
sourcepub fn scale_factor(&self) -> f64
pub fn scale_factor(&self) -> f64
Returns the scale factor that can be used to map logical pixels to physical pixels, and vice versa.
See the dpi
module for more information.
Platform-specific
- X11: Can be overridden using the
WINIT_X11_SCALE_FACTOR
environment variable. - Android: Always returns 1.0.
- Web: Always returns 1.0
sourcepub fn video_modes(&self) -> impl Iterator<Item = VideoMode>
pub fn video_modes(&self) -> impl Iterator<Item = VideoMode>
Returns all fullscreen video modes supported by this monitor.
Platform-specific
- Web: Always returns an empty iterator
