详细说明
size 类型指具有width 和height 属性的值。
size 类型的属性默认值为Qt.size(-1, -1) 。
例如，要读取 `Image::sourceSize ` 大小类型属性的 `width ` 和 `height ` 值：
Column {
Image { id: image; source: "logo.png" }
Text { text: image.sourceSize.width + "," + image.sourceSize.height }
}要创建一个 `size ` 值，请将其指定为“宽度 x 高度”格式的字符串：
Image { sourceSize: "150x50" }或者使用Qt.size() 函数：
Image { sourceSize: Qt.size(150, 50) }在与 C++ 集成时，请注意：从 C++ 传递到 QML 的任何QSize 或QSizeF 值都会自动转换为size 值，反之亦然。当size 值传递给 C++ 时，它会自动转换为QSizeF 值。
