详细描述

此类属于 QWaylandXdgShellV6 extension and provides a way to extend the functionality of a QWaylandXdgSurfaceV6 with features specific to desktop-style menus for an xdg surface.

It corresponds to the Wayland interface zxdg_popup_v6 .

anchorEdges : const Qt::Edges

Returns the set of edges on the anchor rect that the child surface should be placed relative to. If no edges are specified in a direction, the anchor point should be centered between the edges.

访问函数：

Qt::Edges

anchorEdges () const

anchorRect : const QRect

Returns the anchor rectangle relative to the parent window geometry that the child surface should be placed relative to.

访问函数：

QRect

anchorRect () const

configuredGeometry : const QRect

The window geometry the popup received in the configure event. Relative to the upper left corner of the parent surface.

访问函数：

QRect

configuredGeometry () const

通知程序信号：

void	configuredGeometryChanged ()

flipConstraints : const Qt::Orientations

This property holds the orientations in which the child should flip to fit within the screen.

访问函数：

Qt::Orientations

flipConstraints () const

gravityEdges : const Qt::Edges

Specifies in what direction the surface should be positioned, relative to the anchor point.

访问函数：

Qt::Edges

gravityEdges () const

offset : const QPoint

Returns the surface position relative to the position of the anchor on the anchor rectangle and the anchor on the surface.

访问函数：

QPoint

offset () const

parentXdgSurface : QWaylandXdgSurfaceV6 * const

This property holds the QWaylandXdgSurfaceV6 associated with the parent of this QWaylandXdgPopupV6 .

访问函数：

QWaylandXdgSurfaceV6 *

parentXdgSurface () const

positionerSize : const QSize

Returns the size requested for the window geometry by the positioner object.

访问函数：

QSize

positionerSize () const

resizeConstraints : const Qt::Orientations

This property holds the orientations in which the child should resize to fit within the screen.

访问函数：

Qt::Orientations

resizeConstraints () const

slideConstraints : const Qt::Orientations

This property holds the orientations in which the child should slide to fit within the screen.

访问函数：

Qt::Orientations

slideConstraints () const

unconstrainedPosition : const QPoint

The position of the surface relative to the parent window geometry if the surface is not constrained. I.e. when not moved to fit inside the screen or similar.

访问函数：

QPoint

unconstrainedPosition () const

xdgSurface : QWaylandXdgSurfaceV6 * const

This property holds the QWaylandXdgSurfaceV6 associated with this QWaylandXdgPopupV6 .

[static] QWaylandSurfaceRole *QWaylandXdgPopupV6:: role ()

Returns the surface role for the QWaylandPopupV6.

uint QWaylandXdgPopupV6:: sendConfigure (const QRect & geometry )

Sends a configure event to the client. geometry contains the window geometry relative to the upper left corner of the window geometry of the parent surface.

This implicitly sends a configure event to the corresponding QWaylandXdgSurfaceV6 as well.

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

void QWaylandXdgPopupV6:: sendPopupDone ()

Dismiss the popup. According to the xdg-shell-unstable-v6 protocol this should make the client destroy the popup.

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

该函数在 Qt 5.14 引入。
