## Detailed Description

This class is part of the QWaylandWlShell extension and provides a way to extend the functionality of an existing QWaylandSurface with features specific to desktop-style compositors, such as resizing and moving the surface.

It corresponds to the Wayland interface `wl_shell_surface`.

## Member Type Documentation

### enum QWaylandWlShellSurface::ResizeEdge

This enum type provides a way to specify an edge or corner of the surface.

Constant | Value | Description
--- | --- | ---
`QWaylandWlShellSurface::NoneEdge` | `0` | No edge.
`QWaylandWlShellSurface::TopEdge` | `1` | The top edge.
`QWaylandWlShellSurface::BottomEdge` | `2` | The bottom edge.
`QWaylandWlShellSurface::LeftEdge` | `4` | The left edge.
`QWaylandWlShellSurface::TopLeftEdge` | `5` | The top left corner.
`QWaylandWlShellSurface::BottomLeftEdge` | `6` | The bottom left corner.
`QWaylandWlShellSurface::RightEdge` | `8` | The right edge.
`QWaylandWlShellSurface::TopRightEdge` | `9` | The top right corner.
`QWaylandWlShellSurface::BottomRightEdge` | `10` | The bottom right corner.

## Member Function Documentation

### QWaylandWlShellSurface::QWaylandWlShellSurface()

Constructs a QWaylandWlShellSurface.

### QWaylandWlShellSurface::QWaylandWlShellSurface(QWaylandWlShell *shell, QWaylandSurface *surface, const QWaylandResource &res)

Constructs a QWaylandWlShellSurface for surface and initializes it with the given shell and resource res.

### `[static]` QWaylandWlShellSurface *QWaylandWlShellSurface::fromResource(wl_resource *resource)

Returns the QWaylandWlShellSurface object associated with the given resource, or null if no such object exists.

### `[invokable]` void QWaylandWlShellSurface::initialize(QWaylandWlShell *shell, QWaylandSurface *surface, const QWaylandResource &resource)

Initializes the QWaylandWlShellSurface and associates it with the given shell, surface, and resource.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

### `[slot]` void QWaylandWlShellSurface::ping()

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

### `[invokable]` void QWaylandWlShellSurface::sendConfigure(const QSize &size, QWaylandWlShellSurface::ResizeEdge edges)

Sends a configure event to the client, suggesting that it resize its surface to the provided size. The edges provide a hint about how the surface was resized.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

### `[invokable]` void QWaylandWlShellSurface::sendPopupDone()

Sends a popup_done event to the client to indicate that the user has clicked somewhere outside the client's surfaces.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.
