When writing a QWaylandCompositor in Qt Quick, this class can be used to display a client's contents on an output device and will pass user input to the client.
By default, the item locks the current buffer until a new buffer is available and updatePaintNode () is called. Set this property to true to allow Qt to release the buffer immediately when the throttling view is no longer using it. This is useful for items that have slow update intervals.
访问函数:
bool | allowDiscardFrontBuffer () const |
void | setAllowDiscardFrontBuffer (bool discard ) |
通知程序信号:
void | allowDiscardFrontBufferChanged () |
This property holds whether the item's buffer is currently locked. As long as the buffer is locked, it will not be released and returned to the client.
默认为 false。
访问函数:
bool | isBufferLocked () const |
void | setBufferLocked (bool locked ) |
通知程序信号:
void | bufferLockedChanged () |
[read-only]
compositor
:
QWaylandCompositor
* const
This property holds the compositor for the surface rendered by this QWaylandQuickItem .
访问函数:
QWaylandCompositor * | compositor () const |
通知程序信号:
void | compositorChanged () |
This property specifies whether the QWaylandQuickItem should take focus when it is clicked or touched.
默认为
true
.
访问函数:
bool | focusOnClick () const |
void | setFocusOnClick (bool focus ) |
通知程序信号:
void | focusOnClickChanged () |
[read-only]
origin
: const
QWaylandSurface::Origin
This property holds the origin of the QWaylandQuickItem .
访问函数:
QWaylandSurface::Origin | origin () const |
通知程序信号:
void | originChanged () |
This property holds the output on which this item is displayed.
访问函数:
QWaylandOutput * | output () const |
void | setOutput (QWaylandOutput * output ) |
通知程序信号:
void | outputChanged () |
保持
true
if the item is hidden, though the texture is still updated. As opposed to hiding the item by setting
visible
to
false
, setting this property to
false
will not prevent mouse or keyboard input from reaching item.
访问函数:
bool | isPaintEnabled () const |
void | setPaintEnabled (bool paintEnabled ) |
通知程序信号:
void | paintEnabledChanged () |
This property holds the surface rendered by this QWaylandQuickItem .
访问函数:
QWaylandSurface * | surface () const |
void | setSurface (QWaylandSurface * surface ) |
通知程序信号:
void | surfaceChanged () |
This property holds
true
if touch events are forwarded to the client surface,
false
否则。
访问函数:
bool | touchEventsEnabled () const |
void | setTouchEventsEnabled (bool enabled ) |
通知程序信号:
void | touchEventsEnabledChanged () |
Constructs a QWaylandQuickItem with the given parent .
[override virtual noexcept]
QWaylandQuickItem::
~QWaylandQuickItem
()
Destroy the QWaylandQuickItem .
返回
true
if the input region of this item's surface contains the position given by
localPosition
.
[invokable]
QPointF
QWaylandQuickItem::
mapFromSurface
(const
QPointF
&
point
) const
Maps the given point in the Wayland surfaces's coordinate system to the equivalent point within this item's coordinate system, and returns the mapped coordinate.
注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .
[invokable]
QPointF
QWaylandQuickItem::
mapToSurface
(const
QPointF
&
point
) const
Maps the given point in this item's coordinate system to the equivalent point within the Wayland surface's coordinate system, and returns the mapped coordinate.
注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .
[invokable]
void
QWaylandQuickItem::
setPrimary
()
Makes this QWaylandQuickItem 's view the primary view for the surface.
注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

[signal]
void
QWaylandQuickItem::
surfaceDestroyed
()
This signal is emitted when the client has destroyed the
wl_surface
associated with the
QWaylandQuickItem
. The handler for this signal is expected to either destroy the
QWaylandQuickItem
immediately or start a close animation and then destroy the Item.
If an animation is started, bufferLocked should be set to ensure the item keeps its content until the animation finishes
另请参阅 QWaylandQuickItem::bufferLocked .
[virtual slot]
void
QWaylandQuickItem::
takeFocus
(
QWaylandSeat
*
device
= nullptr)
Calling this function causes the item to take the focus of the input device .
[override virtual]
QSGTextureProvider
*QWaylandQuickItem::
textureProvider
() const
重实现: QQuickItem::textureProvider() const .
Returns the texture provider of this QWaylandQuickItem .
Returns the view rendered by this QWaylandQuickItem .
