CdkMonitor objects represent the individual outputs that are
associated with a CdkDisplay. CdkDisplay has APIs to enumerate
monitors with cdk_display_get_n_monitors() and cdk_display_get_monitor(), and
to find particular monitors with cdk_display_get_primary_monitor() or
cdk_display_get_monitor_at_window().
CdkMonitor was introduced in CTK+ 3.22 and supersedes earlier APIs in CdkScreen to obtain monitor-related information.
CdkDisplay *
cdk_monitor_get_display (CdkMonitor *monitor);
Gets the display that this monitor belongs to.
Since: 3.22
void cdk_monitor_get_geometry (CdkMonitor *monitor,CdkRectangle *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 cdk_monitor_get_scale_factor()).
Since: 3.22
void cdk_monitor_get_workarea (CdkMonitor *monitor,CdkRectangle *workarea);
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
cdk_monitor_get_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.
Since: 3.22
int
cdk_monitor_get_width_mm (CdkMonitor *monitor);
Gets the width in millimeters of the monitor.
Since: 3.22
int
cdk_monitor_get_height_mm (CdkMonitor *monitor);
Gets the height in millimeters of the monitor.
Since: 3.22
const char *
cdk_monitor_get_manufacturer (CdkMonitor *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
const char *
cdk_monitor_get_model (CdkMonitor *monitor);
Gets the a string identifying the monitor model, if available.
int
cdk_monitor_get_scale_factor (CdkMonitor *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 window
where it is better to use cdk_window_get_scale_factor() instead.
Since: 3.22
int
cdk_monitor_get_refresh_rate (CdkMonitor *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.
Since: 3.22
CdkSubpixelLayout
cdk_monitor_get_subpixel_layout (CdkMonitor *monitor);
Gets information about the layout of red, green and blue primaries for each pixel in this monitor, if available.
Since: 3.22
gboolean
cdk_monitor_is_primary (CdkMonitor *monitor);
Gets whether this monitor should be considered primary
(see cdk_display_get_primary_monitor()).
Since: 3.22
This enumeration describes how the red, green and blue components of physical pixels on an output device are laid out.
