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
The currently active PlasmaWindow, the PlasmaWindow which returns true in PlasmaWindow::isActive or nullptr in case there is no active window.

Definition at line 345 of file plasmawindowmanagement.cpp.

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

The active window changed.

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

Factory method to create a PlasmaWindowModel.

a new created PlasmaWindowModel

Definition at line 350 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.

Definition at line 272 of file plasmawindowmanagement.cpp.

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

Definition at line 300 of file plasmawindowmanagement.cpp.

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

Same as calling setShowingDesktop with false.

See also

Definition at line 320 of file plasmawindowmanagement.cpp.

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

This signal is emitted right before the data is destroyed.

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

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.

Definition at line 335 of file plasmawindowmanagement.cpp.

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

Definition at line 305 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.

Definition at line 281 of file plasmawindowmanagement.cpp.

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

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

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

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

Sets the queue to use for creating a Surface.

Definition at line 295 of file plasmawindowmanagement.cpp.

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

Requests to change the showing desktop state to show.

See also

Definition at line 330 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 290 of file plasmawindowmanagement.cpp.

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

Same as calling setShowingDesktop with true.

See also

Definition at line 325 of file plasmawindowmanagement.cpp.

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

The showing desktop state changed.

windows stacking order

Definition at line 355 of file plasmawindowmanagement.cpp.

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

The stacking order changed.

void KWayland::Client::PlasmaWindowManagement::windowCreated ( KWayland::Client::PlasmaWindow window)

A new window got created.

See also
QList< PlasmaWindow * > KWayland::Client::PlasmaWindowManagement::windows ( ) const
All windows currently known to the PlasmaWindowManagement
