详细描述

This type is part of the XdgShell extension and provides a way to extend extend the functionality of an XdgSurface with features specific to desktop-style menus for an xdg surface.

It corresponds to the Wayland interface xdg_popup .

特性文档编制

anchorEdges : enumeration

This property holds 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.

可能的值包括：

常量	描述
`Qt.TopEdge`	矩形上边缘。
`Qt.LeftEdge`	矩形左边缘。
`Qt.RightEdge`	矩形右边缘。
`Qt.BottomEdge`	矩形下边缘。

anchorRect : rect

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

configuredGeometry : rect

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

flipConstraints : enumeration

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

可能的值：

常量	描述
`Qt.Horizontal`	Horizontal
`Qt.Vertical`	Vertical

gravityEdges : rect

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

可能的值包括：

常量	描述
`Qt.TopEdge`	The surface should slide towards the top of the screen.
`Qt.LeftEdge`	The surface should slide towards the left of the screen.
`Qt.RightEdge`	The surface should slide towards the right of the screen.
`Qt.BottomEdge`	The surface should slide towards the bottom of the screen.

offset : point

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

parentXdgSurface : XdgSurface

此特性保持 XdgSurface associated with the parent of this XdgPopup .

positionerSize : size

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

resizeConstraints : enumeration

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

可能的值：

常量	描述
`Qt.Horizontal`	Horizontal
`Qt.Vertical`	Vertical

slideConstraints : enumeration

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

可能的值：

常量	描述
`Qt.Horizontal`	Horizontal
`Qt.Vertical`	Vertical

unconstrainedPosition : point

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.

xdgSurface : XdgSurface

此特性保持 XdgSurface associated with this XdgPopup .

方法文档编制

int sendConfigure ( rect 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 XdgSurface 还。

void sendPopupDone ()

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

This method was introduced in Qt 5.14.
