Object representing an output.
Gdk::Monitor objects represent the individual outputs that are associated with a Gdk::Display. Display has APIs to enumerate monitors with Display::get_n_monitors() and Display::get_monitor() and to find particular monitors with Display::get_primary_monitor(), Display::get_monitor_at_point() or Display::get_monitor_at_window().
Monitor was introduced in gtkmm 3.22 and supersedes earlier APIs in Gdk::Screen to obtain monitor-related information.

Glib::RefPtr<Display> Gdk::Monitor::get_display | ( | ) |
Glib::RefPtr<const Display> Gdk::Monitor::get_display | ( | ) | const |
void Gdk::Monitor::get_geometry | ( | Rectangle& | geometry | ) | const |
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 get_scale_factor()).
geometry | A Gdk::Rectangle to be filled wiht the monitor geometry. |
int Gdk::Monitor::get_height_mm | ( | ) | const |
Gets the height in millimeters of the monitor.
Glib::ustring Gdk::Monitor::get_manufacturer | ( | ) | const |
Gets the name of the monitor's manufacturer, if available.
nullptr
. Glib::ustring Gdk::Monitor::get_model | ( | ) | const |
Gets the a string identifying the monitor model, if available.
nullptr
. int Gdk::Monitor::get_refresh_rate | ( | ) | const |
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.
int Gdk::Monitor::get_scale_factor | ( | ) | const |
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 Gdk::Window::get_scale_factor() instead.
SubpixelLayout Gdk::Monitor::get_subpixel_layout | ( | ) | const |
Gets information about the layout of red, green and blue primaries for each pixel in this monitor, if available.
|
static |
Get the GType for this class, for use with the underlying GObject type system.
int Gdk::Monitor::get_width_mm | ( | ) | const |
Gets the width in millimeters of the monitor.
void Gdk::Monitor::get_workarea | ( | Rectangle& | workarea | ) | const |
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 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.
workarea | A Gdk::Rectangle to be filled with the monitor workarea. |
