Provided Methods§
sourcefn connector(&self) -> Option<GString>
fn connector(&self) -> Option<GString>
Gets the name of the monitor’s connector, if available.
These are strings such as “eDP-1”, or “HDMI-2”. They depend on software and hardware configuration, and should not be relied on as stable identifiers of a specific monitor.
§Returns
the name of the connector
sourcefn description(&self) -> Option<GString>
Available on crate feature v4_10
only.
fn description(&self) -> Option<GString>
v4_10
only.Gets a string describing the monitor, if available.
This can be used to identify a monitor in the UI.
§Returns
the monitor description
sourcefn manufacturer(&self) -> Option<GString>
fn manufacturer(&self) -> Option<GString>
Gets the name or PNP ID of the monitor’s manufacturer.
Note that this value might also vary depending on actual display backend.
The PNP ID registry is located at https://uefi.org/pnp_id_list.
§Returns
the name of the manufacturer
sourcefn refresh_rate(&self) -> i32
fn refresh_rate(&self) -> i32
Gets the refresh rate of the monitor, if available.
The value is in milli-Hertz, so a refresh rate of 60Hz is returned as 60000.
§Returns
the refresh rate in milli-Hertz, or 0
sourcefn scale(&self) -> f64
Available on crate feature v4_14
only.
fn scale(&self) -> f64
v4_14
only.Gets the internal scale factor that maps from monitor coordinates to device pixels.
This can be used if you want to create pixel based data for a
particular monitor, but most of the time you’re drawing to a surface
where it is better to use SurfaceExt::scale()
instead.
§Returns
the scale
sourcefn scale_factor(&self) -> i32
fn scale_factor(&self) -> i32
Gets the internal scale factor that maps from monitor coordinates to device pixels.
On traditional systems this is 1, but on very high density outputs it can be a higher value (often 2).
This can be used if you want to create pixel based data for a
particular monitor, but most of the time you’re drawing to a surface
where it is better to use SurfaceExt::scale_factor()
instead.
§Returns
the scale factor
sourcefn subpixel_layout(&self) -> SubpixelLayout
fn subpixel_layout(&self) -> SubpixelLayout
Gets information about the layout of red, green and blue primaries for pixels.
§Returns
the subpixel layout
sourcefn connect_invalidate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_invalidate<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
Emitted when the output represented by @monitor gets disconnected.
fn connect_connector_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
fn connect_description_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
v4_10
only.fn connect_geometry_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
fn connect_height_mm_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
fn connect_manufacturer_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
fn connect_model_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
fn connect_refresh_rate_notify<F: Fn(&Self) + 'static>( &self, f: F, ) -> SignalHandlerId
fn connect_scale_notify<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId
v4_14
only.
