Detailed Description

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().

Since gtkmm 3.22:

Member Function Documentation

Glib::ustring Gdk::Monitor::get_connector ( ) const

Gets the name of the monitor's connector, if available.

Returns
The name of the connector.
Glib::RefPtr<Display> Gdk::Monitor::get_display ( )

Gets the display that this monitor belongs to.

Returns
The display.
Glib::RefPtr<const Display> Gdk::Monitor::get_display ( ) const

Gets the display that this monitor belongs to.

Returns
The display.
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()).

Parameters
geometryA Gdk::Rectangle to be filled with the monitor geometry.
int Gdk::Monitor::get_height_mm ( ) const

Gets the height in millimeters of the monitor.

Returns
The physical height of the monitor.
Glib::ustring Gdk::Monitor::get_manufacturer ( ) const

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 nullptr.
Glib::ustring Gdk::Monitor::get_model ( ) const

Gets the string identifying the monitor model, if available.

Returns
The monitor model, or 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.

Returns
The refresh rate in milli-Hertz, or 0.
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 surface where it is better to use Gdk::Surface::get_scale_factor() instead.

Returns
The scale factor.
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.

Returns
The subpixel layout.
static GType Gdk::Monitor::get_type ( )
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.

Returns
The physical width of the monitor.
GdkMonitor* Gdk::Monitor::gobj ( )
inline

Provides access to the underlying C GObject.

const GdkMonitor* Gdk::Monitor::gobj ( ) const
inline

Provides access to the underlying C GObject.

GdkMonitor* Gdk::Monitor::gobj_copy ( )

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

bool Gdk::Monitor::is_valid ( ) const

Returns true if the monitor object corresponds to a physical monitor.

The monitor becomes invalid when the physical monitor is unplugged or removed.

Returns
true if the object corresponds to a physical monitor.

Glib::PropertyProxy_ReadOnly< Gdk::Rectangle > Gdk::Monitor::property_geometry ( ) const

The geometry of the monitor.

Default value: Gdk::SubpixelLayout::UNKNOWN

Returns
A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.
Glib::PropertyProxy_ReadOnly< bool > Gdk::Monitor::property_valid ( ) const

Glib::SignalProxy<void()> Gdk::Monitor::signal_invalidate ( )
Slot Prototype:
void on_my_invalidate()

Flags: Run First

The signal_invalidate() signal gets emitted when the output represented by monitor gets disconnected.
