| typedef void(*)(gpointer data | DestroyNotify) | 
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_monitor_at_surface().

| 
 | protected | 
| Glib::ustring Gdk::Monitor::get_connector | ( | ) | const | 
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.
| Glib::ustring Gdk::Monitor::get_description | ( | ) | const | 
Gets a string describing the monitor, if available.
This can be used to identify a monitor in the UI.
| Glib::RefPtr< Display > Gdk::Monitor::get_display | ( | ) | 
Gets the display that this monitor belongs to.
| Glib::RefPtr< const Display > Gdk::Monitor::get_display | ( | ) | const | 
Gets the display that this monitor belongs to.
| void Gdk::Monitor::get_geometry | ( | Rectangle & | geometry | ) | const | 
Retrieves the size and position of the monitor within the display coordinate space.
The returned geometry is in ”application pixels”, not in ”device pixels” (see get_scale()).
| geometry | A Gdk::Rectangleto be filled with 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 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.
| Glib::ustring Gdk::Monitor::get_model | ( | ) | const | 
Gets the string identifying the monitor model, if available.
| 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.
| double Gdk::Monitor::get_scale | ( | ) | const | 
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 Gdk::Surface::get_scale() instead.
| int Gdk::Monitor::get_scale_factor | ( | ) | const | 
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 Gdk::Surface::get_scale_factor() instead.
| SubpixelLayout Gdk::Monitor::get_subpixel_layout | ( | ) | const | 
Gets information about the layout of red, green and blue primaries for pixels.
| 
 | 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.
