Detailed Description

Wrapper for the wl_shell interface.

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

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

Shell *s = registry->createShell(name, version);

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

Shell *s = new Shell;
s->setup(registry->bindShell(name, version));

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

Member Function Documentation

ShellSurface * KWayland::Client::Shell::createSurface	(	wl_surface *	surface,
		QObject *	parent = nullptr
	)

Creates a ShellSurface for the given surface and sets it up.

Parameters

surface	The native surface to create the ShellSurface for
parent	The parent to use for the ShellSurface

Returns

created ShellSurface

Definition at line 78 of file shell.cpp.

ShellSurface * KWayland::Client::Shell::createSurface	(	Surface *	surface,
		QObject *	parent = nullptr
	)

Creates a ShellSurface for the given surface and sets it up.

Parameters

surface	The Surface to create the ShellSurface for
parent	The parent to use for the ShellSurface

Returns

created ShellSurface

Definition at line 92 of file shell.cpp.

void KWayland::Client::Shell::destroy

(

)

Destroys the data held by this Shell.

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 wl_shell interface once there is a new connection available.

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

connect(connection, &ConnectionThread::connectionDied, shell, &Shell::destroy);

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

release

interfaceAboutToBeDestroyed

Definition at line 43 of file shell.cpp.

EventQueue * KWayland::Client::Shell::eventQueue

(

)

Returns

The event queue to use for creating a Surface.

Definition at line 73 of file shell.cpp.

void KWayland::Client::Shell::interfaceAboutToBeDestroyed ( )

signal

This signal is emitted right before the data is destroyed.

void KWayland::Client::Shell::interfaceAboutToBeReleased ( )

signal

This signal is emitted right before the interface is released.

bool KWayland::Client::Shell::isValid

(

)

const

Returns

true if managing a wl_shell.

Definition at line 98 of file shell.cpp.

void KWayland::Client::Shell::release

(

)

Releases the wl_shell interface.

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

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

interfaceAboutToBeReleased

Definition at line 52 of file shell.cpp.

void KWayland::Client::Shell::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::createShell

Since

5.5

void KWayland::Client::Shell::setEventQueue

(

EventQueue *

queue

)

Sets the queue to use for creating a Surface.

Definition at line 68 of file shell.cpp.

void KWayland::Client::Shell::setup

(

wl_shell *

shell

)

Setup this Shell to manage the shell.

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