Detailed Description

Wrapper for the wl_shell_surface interface.

This class is a convenient wrapper for the wl_shell_surface interface.

To create an instance use Shell::createSurface.

Member Enumeration Documentation

enum KWayland::Client::ShellSurface::TransientFlag

strong

Flags which can be passed to a transient surface.

Since

5.5

Enumerator
Default	Default: transient surface accepts keyboard focus.
NoFocus	Transient surface does not accept keyboard focus.

Definition at line 221 of file shell.h.

Property Documentation

QSize KWayland::Client::ShellSurface::size

readwrite

The size of the ShellSurface.

Member Function Documentation

void KWayland::Client::ShellSurface::destroy

(

)

Destroys the data held by this ShellSurface.

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 wl_shell_surface interface once there is a new connection available.

This method is automatically invoked when the Shell which created this ShellSurface gets destroyed.

ShellSurface * KWayland::Client::ShellSurface::fromQtWinId ( WId  wid )

static

Creates a ShellSurface for the given winId.

This is an integration feature for QtWayland. On non-wayland platforms this method returns nullptr as well as for not created QWindows.

The returned ShellSurface will be fully setup, but won't be released. It gets automatically destroyed together with the QWindow corresponding the wid.

Since

5.28

Definition at line 170 of file shell.cpp.

ShellSurface * KWayland::Client::ShellSurface::fromWindow ( QWindow *  window )

static

Creates a ShellSurface for the given window.

This is an integration feature for QtWayland. On non-wayland platforms this method returns nullptr as well as for not created QWindows.

The returned ShellSurface will be fully setup, but won't be released. It gets automatically destroyed together with the window.

Since

5.28

Definition at line 148 of file shell.cpp.

ShellSurface * KWayland::Client::ShellSurface::get ( wl_shell_surface *  native )

static

Returns

The Surface referencing the native wl_surface or null if there is no such Surface.

Since

5.28

Definition at line 187 of file shell.cpp.

void KWayland::Client::ShellSurface::pinged ( )

signal

Signal is emitted when the ShellSurface received a ping request.

The ShellSurface automatically responds to the ping.

void KWayland::Client::ShellSurface::popupDone ( )

signal

The popupDone signal is sent out when a popup grab is broken, that is, when the user clicks a surface that doesn't belong to the client owning the popup surface.

5.33

void KWayland::Client::ShellSurface::release

(

)

Releases the wl_shell_surface interface.

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

This method is automatically invoked when the Shell which created this ShellSurface gets released.

Definition at line 213 of file shell.cpp.

void KWayland::Client::ShellSurface::requestMove	(	Seat *	seat,
		quint32	serial
	)

Requests a move on the given seat after the pointer button press with the given serial.

Parameters

seat	The seat on which to move the window
serial	The serial of the pointer button press which should trigger the move

Since

5.5

Definition at line 313 of file shell.cpp.

void KWayland::Client::ShellSurface::requestResize	(	Seat *	seat,
		quint32	serial,
		Qt::Edges	edges
	)

Requests a resize on the given seat after the pointer button press with the given serial.

Parameters

seat	The seat on which to resize the window
serial	The serial of the pointer button press which should trigger the resize
edges	A hint for the compositor to set e.g. an appropriate cursor image

Since

5.5

Definition at line 321 of file shell.cpp.

void KWayland::Client::ShellSurface::setFullscreen

(

Output *

output = nullptr

)

Sets the ShellSurface fullscreen on output.

Definition at line 273 of file shell.cpp.

void KWayland::Client::ShellSurface::setTitle

(

const QString &

title

)

Sets a short title for the surface.

This string may be used to identify the surface in a task bar, window list, or other user interface elements provided by the compositor.

Since

5.55

Definition at line 352 of file shell.cpp.

void KWayland::Client::ShellSurface::setTransient	(	Surface *	parent,
		const QPoint &	offset = QPoint(),
		TransientFlags	flags = TransientFlag::Default
	)

Sets this Surface as a transient for parent.

Parameters

parent	The parent Surface of this surface
offset	The offset of this Surface in the parent coordinate system
flags	The flags for the transient

Since

5.5

Definition at line 291 of file shell.cpp.

void KWayland::Client::ShellSurface::setTransientPopup	(	Surface *	parent,
		Seat *	grabbedSeat,
		quint32	grabSerial,
		const QPoint &	offset = QPoint(),
		TransientFlags	flags = TransientFlag::Default
	)

Sets this Surface as a popup transient for parent.

A popup is a transient with an added pointer grab on the grabbedSeat.

The popup grab can be created if the client has an implicit grab (e.g. button press) on the grabbedSeat. It needs to pass the grabSerial indicating the implicit grab to the request for setting the surface. The implicit grab is turned into a popup grab which will persist after the implicit grab ends. The popup grab ends when the ShellSurface gets destroyed or when the compositor breaks the grab through the popupDone signal.

Parameters

parent	The parent Surface of this ShellSurface
grabbedSeat	The Seat on which an implicit grab exists
grabSerial	The serial of the implicit grab
offset	The offset of this Surface in the parent coordinate system
flags	The flags for the transient

Since

5.33

Definition at line 301 of file shell.cpp.

void KWayland::Client::ShellSurface::setup

(

wl_shell_surface *

surface

)

Setup this ShellSurface to manage the surface.

There is normally no need to call this method as it's invoked by Shell::createSurface.

Definition at line 253 of file shell.cpp.

void KWayland::Client::ShellSurface::setWindowClass

(

const QByteArray &

windowClass

)

Sets a window class for the surface.

The surface class identifies the general class of applications to which the surface belongs. A common convention is to use the file name (or the full path if it is a non-standard location) of the application's .desktop file as the class.
