53 \brief The LayoutItem element allows you to place your declarative UI elements inside a classical Qt layout. |
|
54 |
|
55 LayoutItem is a variant of Item with a couple of additional properties. These properties provide the size hints |
|
56 needed for items to work in conjunction with Qt Layouts. The Qt Layout will resize the LayoutItem as appropriate, |
|
57 taking its size hints into account, and you can propagate this to the other elements in your UI via anchors and bindings. |
|
58 |
|
59 This is a QGraphicsLayoutItem subclass, and the properties merely expose the QGraphicsLayoutItem functionality to QML. |
|
60 See the QGraphicsLayoutItem documentation for further details. |
