Detailed Description

Wrapper for the org_kde_plasma_window_management interface.

PlasmaWindowManagement is a privileged interface. A Wayland compositor is allowed to ignore any requests. The PlasmaWindowManagement allows to get information about the overall windowing system. It allows to see which windows are currently available and thus is the base to implement e.g. a task manager.

This class provides a convenient wrapper for the org_kde_plasma_window_management interface. It's main purpose is to create a PlasmaWindowManagementSurface.

To use this class one needs to interact with the Registry. There are two possible ways to create the Shell interface:

PlasmaWindowManagement *s = registry->createPlasmaWindowManagement(name, version);

This creates the PlasmaWindowManagement and sets it up directly. As an alternative this can also be done in a more low level way:

PlasmaWindowManagement *s = new PlasmaWindowManagement;
s->setup(registry->bindPlasmaWindowManagement(name, version));

The PlasmaWindowManagement can be used as a drop-in replacement for any org_kde_plasma_window_management pointer as it provides matching cast operators.

Member Function Documentation

PlasmaWindow * KWayland::Client::PlasmaWindowManagement::activeWindow ( ) const
Returns
The currently active PlasmaWindow, the PlasmaWindow which returns true in PlasmaWindow::isActive or nullptr in case there is no active window.

Definition at line 385 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::activeWindowChanged ( )
signal

The active window changed.

See also
activeWindow
PlasmaWindowModel * KWayland::Client::PlasmaWindowManagement::createWindowModel ( )

Factory method to create a PlasmaWindowModel.

Returns
a new created PlasmaWindowModel

Definition at line 390 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::destroy ( )

Destroys the data held by this PlasmaWindowManagement.

This method is supposed to be used when the connection to the Wayland server goes away. Once the connection becomes invalid, 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_plasma_window_management interface once there is a new connection available.

This method is automatically invoked when the Registry which created this PlasmaWindowManagement gets destroyed.

Right before the data is destroyed, the signal interfaceAboutToBeDestroyed is emitted.

release
interfaceAboutToBeDestroyed

Definition at line 312 of file plasmawindowmanagement.cpp.

EventQueue * KWayland::Client::PlasmaWindowManagement::eventQueue ( )
Returns
The event queue to use for creating a Surface.

Definition at line 340 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::hideDesktop ( )

Same as calling setShowingDesktop with false.

See also
setShowingDesktop

Definition at line 360 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::interfaceAboutToBeDestroyed ( )
signal

This signal is emitted right before the data is destroyed.

void KWayland::Client::PlasmaWindowManagement::interfaceAboutToBeReleased ( )
signal

This signal is emitted right before the interface is released.

bool KWayland::Client::PlasmaWindowManagement::isShowingDesktop ( ) const

Whether the system is currently showing the desktop.

This means that the system focuses on the desktop and hides other windows.

See also
setShowingDesktop
showDesktop
hideDesktop
showingDesktopChanged

Definition at line 375 of file plasmawindowmanagement.cpp.

bool KWayland::Client::PlasmaWindowManagement::isValid ( ) const
Returns
true if managing a org_kde_plasma_window_management.

Definition at line 345 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::release ( )

Releases the org_kde_plasma_window_management interface.

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

Right before the interface is released the signal interfaceAboutToBeReleased is emitted.

See also
interfaceAboutToBeReleased

Definition at line 321 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::removed ( )
signal

The corresponding global for this interface on the Registry got removed.

This signal gets only emitted if the Compositor got created by Registry::createPlasmaWindowManagement

Since
5.5
void KWayland::Client::PlasmaWindowManagement::setEventQueue ( EventQueue queue)

Sets the queue to use for creating a Surface.

Definition at line 335 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::setShowingDesktop ( bool  show)

Requests to change the showing desktop state to show.

isShowingDesktop
showDesktop
hideDesktop

Definition at line 370 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::setup ( org_kde_plasma_window_management *  shell)

Setup this Shell to manage the shell.

When using Registry::createShell there is no need to call this method.

Definition at line 330 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::showDesktop ( )

Same as calling setShowingDesktop with true.

See also
setShowingDesktop

Definition at line 365 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::showingDesktopChanged ( bool  )
signal

The showing desktop state changed.

QVector< quint32 > KWayland::Client::PlasmaWindowManagement::stackingOrder ( ) const
Returns
windows stacking order
Deprecated:
Since 5.73, use stackingOrderUuids()

Definition at line 395 of file plasmawindowmanagement.cpp.

void KWayland::Client::PlasmaWindowManagement::stackingOrderChanged ( )
signal

The stacking order changed.

Since
5.70
Deprecated:
Since 5.73, use stackingOrderUuidsChanged()
QVector< QByteArray > KWayland::Client::PlasmaWindowManagement::stackingOrderUuids ( ) const

void KWayland::Client::PlasmaWindowManagement::stackingOrderUuidsChanged ( )
signal

The stacking order uuids changed.

Since
