This class encapsulates a rectangular area of pixels that is displayed on an output device. It corresponds to the interface
wl_surface
in the Wayland protocol.
This enum type is used to specify the origin of a QWaylandSurface 's buffer.
| 常量 | 值 | 描述 |
|---|---|---|
QWaylandSurface::OriginTopLeft
|
0
|
The origin is the top left corner of the buffer. |
QWaylandSurface::OriginBottomLeft
|
1
|
The origin is the bottom left corner of the buffer. |
此特性保持 QWaylandSurface 's buffer scale. The buffer scale lets a client supply higher resolution buffer data for use on high resolution outputs.
访问函数：
| int | bufferScale () const |
通知程序信号：
| void | bufferScaleChanged () |
This property holds the size of the current buffer of this QWaylandSurface in pixels, not in surface coordinates.
For the size in surface coordinates, use destinationSize 代替。
访问函数：
| QSize | bufferSize () const |
通知程序信号：
| void | bufferSizeChanged () |
另请参阅 destinationSize and bufferScale .
This property holds the client using this QWaylandSurface .
访问函数：
| QWaylandClient * | client () const |
This property holds the orientation of the QWaylandSurface 's contents.
访问函数：
| Qt::ScreenOrientation | contentOrientation () const |
通知程序信号：
| void | contentOrientationChanged () |

This property holds whether the QWaylandSurface is a cursor surface.
访问函数：
| bool | isCursorSurface () const |
| void | markAsCursorSurface (bool cursorSurface ) |
通知程序信号：
| void | cursorSurfaceChanged () |
This property holds the size of this WaylandSurface in surface coordinates.
该特性在 Qt 5.13 引入。
访问函数：
| QSize | destinationSize () const |

This property holds whether the QWaylandSurface has content.
访问函数：
| bool | hasContent () const |
通知程序信号：
| void | hasContentChanged () |
This property holds whether this surface is intended to inhibit the idle behavior of the compositor such as screen blanking, locking and screen saving.
该特性在 Qt 5.14 引入。
访问函数：
| bool | inhibitsIdle () const |
通知程序信号：
| void | inhibitsIdleChanged () |
另请参阅 QWaylandIdleInhibitManagerV1 .
This property holds the origin of the QWaylandSurface 's buffer, or QWaylandSurface::OriginTopLeft if the surface has no buffer.
访问函数：
| QWaylandSurface::Origin | origin () const |
通知程序信号：
| void | originChanged () |
This property describes the portion of the attached QWaylandBuffer that should be drawn on the screen. The coordinates are from the corner of the buffer and are scaled by bufferScale .

Constructs and initializes a QWaylandSurface for the given compositor and client ，和采用给定 id and version .
Constructs a an uninitialized QWaylandSurface.
[signal]
void
QWaylandSurface::
childAdded
(
QWaylandSurface
*
child
)
This signal is emitted when a wl_subsurface, child , has been added to the surface.
[signal]
void
QWaylandSurface::
dragStarted
(
QWaylandDrag
*
drag
)
This signal is emitted when a drag has started from this surface.
[signal]
void
QWaylandSurface::
surfaceDestroyed
()
This signal is emitted when the corresponing wl_surface is destroyed.
[slot]
void
QWaylandSurface::
updateSelection
()
Updates the surface with the compositor's retained clipboard selection. Although this is done automatically when the surface receives keyboard focus, this function is useful for updating clients which do not have keyboard focus.

QWaylandSurface::
~QWaylandSurface

销毁 QWaylandSurface .
Returns the compositor for this QWaylandSurface .
销毁 QWaylandSurface .

fromResource
(
::wl_resource

返回 QWaylandSurface corresponding to the Wayland resource resource .
初始化 QWaylandSurface 采用给定 compositor and client ，和采用给定 id and version .

返回
true
若
QWaylandSurface
's input region contains the point

. Otherwise returns
false

返回
true
若

's input region contains the point
position
. Otherwise returns
false
.
该函数在 Qt 5.14 引入。
返回 true 若 QWaylandSurface has been destroyed. Otherwise returns false.
注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .
返回 true 若 QWaylandSurface has been initialized.
Returns this QWaylandSurface 's primary view.
另请参阅 QWaylandView::advance () 和 QWaylandSurface::setPrimaryView ().
Returns the Wayland resource corresponding to this QWaylandSurface .
Sends pending frame callbacks.
注意： 此函数可以被援引，通过元对象系统和从 QML。见 Q_INVOKABLE .
设置此 QWaylandSurface 's primary view to view , in case there are multiple views of this surface. The primary view is the view that governs the client's refresh rate. It takes care of discarding buffer references when QWaylandView::advance () is called. See the documentation for QWaylandView::advance () 了解更多细节。
In shell surface integrations, such as QWaylandWlShellIntegration and QWaylandXdgShellV5Integration, maximize and fullscreen requests from the client will only have an effect if the integration has the primary view of the surface.
另请参阅 primaryView () 和 QWaylandView::advance ().
设置 role on the surface. A role defines how a surface will be mapped on screen; without a role a surface is supposed to be hidden. Only one role can be set on a surface, at all times. Although setting the same role many times is allowed, attempting to change the role of a surface will trigger a protocol error to the errorResource and send an errorCode to the client.
Returns true if a role can be assigned; false otherwise.
Returns the views for this QWaylandSurface .
