## Detailed Description

The QWaylandXdgShell extension provides a way to associate a QWaylandXdgToplevel or QWaylandXdgPopup with a regular Wayland surface. Using the QWaylandXdgToplevel interface, the client can request that the surface is resized, moved, and so on.

QWaylandXdgShell corresponds to the Wayland interface, `xdg_shell`.

## Member Function Documentation

### `[explicit]` QWaylandXdgShell::QWaylandXdgShell()

Constructs a QWaylandXdgShell object.

### `[explicit]` QWaylandXdgShell::QWaylandXdgShell(QWaylandCompositor *compositor)

Constructs a QWaylandXdgShell object for the provided compositor.

### `[override virtual]` void QWaylandXdgShell::initialize()

Reimplements: QWaylandCompositorExtension::initialize().

Initializes the shell extension.

### `[static]` const struct wl_interface *QWaylandXdgShell::interface()

Returns the Wayland interface for the QWaylandXdgShell.

### `[slot]` uint QWaylandXdgShell::ping(QWaylandClient *client)

Sends a ping event to client. If the client replies to the event the pong signal will be emitted.

### `[signal]` void QWaylandXdgShell::pong(uint serial)

This signal is emitted when the client has responded to a ping event with serial, serial.

See also QWaylandXdgShell::ping().

### `[signal]` void QWaylandXdgShell::popupCreated(QWaylandXdgPopup *popup, QWaylandXdgSurface *xdgSurface)

This signal is emitted when the client has created a `xdg_popup`. A common use case is to let the handler of this signal instantiate a QWaylandShellSurfaceItem or QWaylandQuickItem for displaying popup in a QtQuick scene.

xdgSurface is the XdgSurface popup is the role object for.

### `[signal]` void QWaylandXdgShell::toplevelCreated(QWaylandXdgToplevel *toplevel, QWaylandXdgSurface *xdgSurface)

This signal is emitted when the client has created a `xdg_toplevel`. A common use case is to let the handler of this signal instantiate a QWaylandShellSurfaceItem or QWaylandQuickItem for displaying toplevel in a QtQuick scene.

xdgSurface is the XdgSurface toplevel is the role object for.

### `[signal]` void QWaylandXdgShell::xdgSurfaceCreated(QWaylandXdgSurface *xdgSurface)

This signal is emitted when the client has created a `xdg_surface`. Note that xdgSurface is not mapped, i.e. according to the `xdg-shell` protocol it should not be displayed, until it has received a role object.
