Detailed Description

Power management for monitors.

Display Power Management Signaling allows power management for monitors. This class is a convenient wrapper for the org_kde_kwin_dpms interface. To create a Dpms call DpmsManager::getDpms.

Member Function Documentation

void KWayland::Client::Dpms::destroy ( )

Destroys the data held by this Dpms.

This method is supposed to be used when the connection to the Wayland server goes away. If the connection is not valid anymore, it's not possible to call release anymore as that calls into the Wayland connection and the call would fail. This method cleans up the data, so that the instance can be deleted or set up to a new org_kde_kwin_dpms interface once there is a new connection available.

It is suggested to connect this method to ConnectionThread::connectionDied:

Definition at line 203 of file dpms.cpp.

bool KWayland::Client::Dpms::isSupported ( ) const

Whether Dpms is supported for the Output.

Initially set to false.

Returns
whether Dpms is supported for the Output.
See also
supportedChanged

Definition at line 223 of file dpms.cpp.

bool KWayland::Client::Dpms::isValid ( ) const
Returns
true if managing a org_kde_kwin_dpms.

Definition at line 213 of file dpms.cpp.

Dpms::Mode KWayland::Client::Dpms::mode ( ) const

The current Dpms mode.

Initially set to Mode::On.

Returns
the current Dpms mode of the Output
See also
modeChanged

Definition at line 228 of file dpms.cpp.

void KWayland::Client::Dpms::modeChanged ( )
signal

Emitted if the Dpms mode on the Output changes.

See also
mode
QPointer< Output > KWayland::Client::Dpms::output ( ) const
Returns
the Output for which this Dpms got created

Definition at line 255 of file dpms.cpp.

void KWayland::Client::Dpms::release ( )

Releases the org_kde_kwin_dpms interface.

After the interface has been released the Dpms instance is no longer valid and can be setup with another org_kde_kwin_dpms interface.

Definition at line 208 of file dpms.cpp.

void KWayland::Client::Dpms::requestMode ( Dpms::Mode  mode)

Request to change the Output into Dpms mode.

The Wayland compositor is not obliged to honor the request. If the mode changes the client is notified and modeChanged gets emitted.

Parameters
modeThe requested Dpms mode.

Definition at line 233 of file dpms.cpp.

void KWayland::Client::Dpms::setup ( org_kde_kwin_dpms *  dpms)

Setup this Dpms to manage the dpms.

When using DpmsManager::createDpms there is no need to call this method.

Definition at line 218 of file dpms.cpp.

void KWayland::Client::Dpms::supportedChanged ( )
signal

Emitted if the supported state on the Output changes.
