成员函数文档编制

QWaylandXdgToplevel:: QWaylandXdgToplevel ( QWaylandXdgSurface * xdgSurface , QWaylandResource & resource )

Constructs a QWaylandXdgToplevel for the given xdgSurface and resource .

[static] QWaylandXdgToplevel *QWaylandXdgToplevel:: fromResource ( ::wl_resource * resource )

返回 QWaylandXdgToplevel corresponding to the resource .

[static] QWaylandSurfaceRole *QWaylandXdgToplevel:: role ()

Returns the surface role for the QWaylandToplevel.

void QWaylandXdgToplevel:: sendClose ()

Sends a close event to the client. The client may choose to ignore the event.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendConfigure (const QSize & size , const QVector < QWaylandXdgToplevel::State > & 状态 )

Sends a configure event to the client. Parameter size contains the pixel size of the surface. A size of zero means the client is free to decide the size. Known 状态 are enumerated in QWaylandXdgToplevel::State.

uint QWaylandXdgToplevel:: sendFullscreen (const QSize & size )

Convenience for sending a configure event with the fullscreen state set, and maximized and resizing removed. The activated state is left in its current state.

size is the new size of the window.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

另请参阅 sendUnmaximized .

uint QWaylandXdgToplevel:: sendMaximized (const QSize & size )

Convenience for sending a configure event with the maximized state set, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendResizing (const QSize & maxSize )

Convenience for sending a configure event with the resizing state set, and maximized and fullscreen removed. The activated state is left in its current state.

maxSize is the new size of the window.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

uint QWaylandXdgToplevel:: sendUnmaximized (const QSize & size = QSize(0, 0))

Convenience for sending a configure event with the maximized, fullscreen and resizing states removed, and fullscreen and resizing removed. The activated state is left in its current state.

size is the new size of the window. If size is zero, the client decides the size.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .

QSize QWaylandXdgToplevel:: sizeForResize (const QSizeF & size , const QPointF & delta , Qt::Edges edges ) const

Convenience for computing the new size given the current size delta ,和 edges active in the drag.

注意: 此函数可以被援引,通过元对象系统和从 QML。见 Q_INVOKABLE .
