Description
GdkMonitor objects represent the individual outputs that are
associated with a GdkDisplay. GdkDisplay keeps a GListModel to enumerate
and monitor monitors with gdk_display_get_monitors().
You can use gdk_display_get_monitor_at_surface() to find a particular monitor.
Functions
gdk_monitor_get_display ()
GdkDisplay *
gdk_monitor_get_display (GdkMonitor *monitor);
Gets the display that this monitor belongs to.
gdk_monitor_get_geometry ()
void gdk_monitor_get_geometry (GdkMonitor *monitor,GdkRectangle *geometry);
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 gdk_monitor_get_scale_factor()).
gdk_monitor_get_width_mm ()
int
gdk_monitor_get_width_mm (GdkMonitor *monitor);
Gets the width in millimeters of the monitor.
gdk_monitor_get_height_mm ()
int
gdk_monitor_get_height_mm (GdkMonitor *monitor);
Gets the height in millimeters of the monitor.
gdk_monitor_get_manufacturer ()
const char *
gdk_monitor_get_manufacturer (GdkMonitor *monitor);
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
gdk_monitor_get_model ()
const char *
gdk_monitor_get_model (GdkMonitor *monitor);
Gets the string identifying the monitor model, if available.
gdk_monitor_get_connector ()
const char *
gdk_monitor_get_connector (GdkMonitor *monitor);
Gets the name of the monitor's connector, if available.
gdk_monitor_get_scale_factor ()
int
gdk_monitor_get_scale_factor (GdkMonitor *monitor);
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 surface
where it is better to use gdk_surface_get_scale_factor() instead.
gdk_monitor_get_refresh_rate ()
int
gdk_monitor_get_refresh_rate (GdkMonitor *monitor);
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.
gdk_monitor_get_subpixel_layout ()
GdkSubpixelLayout
gdk_monitor_get_subpixel_layout (GdkMonitor *monitor);
Gets information about the layout of red, green and blue primaries for each pixel in this monitor, if available.
gdk_monitor_is_valid ()
gboolean
gdk_monitor_is_valid (GdkMonitor *monitor);
Returns TRUE if the monitor
object corresponds to a
physical monitor. The monitor
becomes invalid when the
physical monitor is unplugged or removed.
Types and Values
GdkMonitor
typedef struct _GdkMonitor GdkMonitor;
The GdkMonitor struct contains only private fields and should not be accessed directly.
enum GdkSubpixelLayout
This enumeration describes how the red, green and blue components of physical pixels on an output device are laid out.
