Struct gdk::Monitor[][src]

pub struct Monitor(_);
Expand description

GdkMonitor objects represent the individual outputs that are associated with a Display. GdkDisplay has APIs to enumerate monitors with Display::n_monitors() and Display::monitor(), and to find particular monitors with Display::primary_monitor() or Display::monitor_at_window().

GdkMonitor was introduced in GTK+ 3.22 and supersedes earlier APIs in GdkScreen to obtain monitor-related information.

Implementations

This is supported on crate feature v3_22 only.

Gets the display that this monitor belongs to.

Returns

the display

This is supported on crate feature v3_22 only.

Retrieves the size and position of an individual monitor within the display coordinate space. The returned geometry is in ”application pixels”, not in ”device pixels” (see scale_factor()).

Returns

geometry

a Rectangle to be filled with the monitor geometry

This is supported on crate feature v3_22 only.

Gets the height in millimeters of the monitor.

Returns

the physical height of the monitor

This is supported on crate feature v3_22 only.

Gets the name or PNP ID of the monitor’s manufacturer, if available.

Note that this value might also vary depending on actual display backend.

PNP ID registry is located at https://uefi.org/pnp_id_list

Returns

the name of the manufacturer, or None

This is supported on crate feature v3_22 only.

Gets the a string identifying the monitor model, if available.

Returns

the monitor model, or None

This is supported on crate feature v3_22 only.

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

This is supported on crate feature v3_22 only.

Gets the internal scale factor that maps from monitor coordinates to the actual device pixels. On traditional systems this is 1, but on very high density outputs this 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 window where it is better to use Window::scale_factor() instead.

Returns

the scale factor

This is supported on crate feature v3_22 only.

Gets information about the layout of red, green and blue primaries for each pixel in this monitor, if available.

Returns

the subpixel layout

This is supported on crate feature v3_22 only.

Gets the width in millimeters of the monitor.

Returns

the physical width of the monitor

This is supported on crate feature v3_22 only.

Retrieves the size and position of the “work area” on a monitor within the display coordinate space. The returned geometry is in ”application pixels”, not in ”device pixels” (see scale_factor()).

The work area should be considered when positioning menus and similar popups, to avoid placing them below panels, docks or other desktop components.

Note that not all backends may have a concept of workarea. This function will return the monitor geometry if a workarea is not available, or does not apply.

Returns

workarea

a Rectangle to be filled with the monitor workarea

This is supported on crate feature v3_22 only.

Gets whether this monitor should be considered primary (see Display::primary_monitor()).

Returns

true if self is primary
