public class Monitor
extends GObject

GdkMonitor objects represent the individual outputs that are associated with a GdkDisplay.

GdkDisplay keeps a GListModel to enumerate and monitor monitors with Display.getMonitors(). You can use Display.getMonitorAtSurface(org.gnome.gdk.Surface) to find a particular monitor.

Constructor Details

Monitor

public Monitor(MemorySegment address)

Create a Monitor proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the Monitor class

Returns:

the GType

asParent

protected Monitor asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class GObject

getConnector

public String getConnector()

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.

Returns:

the name of the connector

getDescription

public String getDescription()

Gets a string describing the monitor, if available.

This can be used to identify a monitor in the UI.

Returns:

the monitor description

getDisplay

public Display getDisplay()

Gets the display that this monitor belongs to.

Returns:

the display

getGeometry

public void getGeometry(Rectangle geometry)

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 getScale()).

Parameters:

geometry - a GdkRectangle to be filled with the monitor geometry

getHeightMm

public int getHeightMm()

Gets the height in millimeters of the monitor.

Returns:

the physical height of the monitor

getManufacturer

public String getManufacturer()

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.

Returns:

the name of the manufacturer

getModel

public String getModel()

Gets the string identifying the monitor model, if available.

Returns:

the monitor model

getRefreshRate

public int getRefreshRate()

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

getScale

public double getScale()

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 Surface.getScale() instead.

Returns:

the scale

getScaleFactor

public int getScaleFactor()

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 Surface.getScaleFactor() instead.

Returns:

the scale factor

getSubpixelLayout

public SubpixelLayout getSubpixelLayout()

Gets information about the layout of red, green and blue primaries for pixels.

Returns:

the subpixel layout

getWidthMm

public int getWidthMm()

Gets the width in millimeters of the monitor.

Returns:

the physical width of the monitor

isValid

public boolean isValid()

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

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

Returns:

true if the object corresponds to a physical monitor

onInvalidate

public SignalConnection<Monitor.InvalidateCallback> onInvalidate(Monitor.InvalidateCallback handler)

Emitted when the output represented by monitor gets disconnected.

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• Monitor.InvalidateCallback.run()

emitInvalidate

public void emitInvalidate()

Emits the "invalidate" signal. See onInvalidate(org.gnome.gdk.Monitor.InvalidateCallback).

builder

public static Monitor.Builder<? extends Monitor.Builder> builder()

A Monitor.Builder object constructs a Monitor with the specified properties. Use the various set...() methods to set properties, and finish construction with Monitor.Builder.build().
