The LayoutItem element allows declarative UI elements to be placed inside Qt's Graphics View layouts. More...

This element was introduced in Qt 4.7.

- List of all members, including inherited members

## Properties

- maximumSize : QSizeF
- minimumSize : QSizeF
- preferredSize : QSizeF

## Detailed Description

LayoutItem is a variant of Item with additional size hint properties. These properties provide the size hints necessary for items to work in conjunction with Qt Graphics View layout classes such as QGraphicsLinearLayout and QGraphicsGridLayout. The Qt layout mechanisms will resize the LayoutItem as appropriate, taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings.

This is a QGraphicsLayoutItem subclass, and its properties merely expose the QGraphicsLayoutItem functionality to QML.

The LayoutItem example demonstrates how a LayoutItem can be used within a Graphics View scene.
