# size QML Value Type

a value with width and height attributes. More...

## Detailed Description

The `size` type refers to a value with has `width` and `height` attributes.

Properties of type `size` have `Qt.size(-1, -1)` as default value.

For example, to read the `width` and `height` values of the Image::sourceSize size-type property:

     Column {
         Image { id: image; source: "logo.png" }
         Text { text: image.sourceSize.width + "," + image.sourceSize.height }
     }

To create a `size` value, specify it as a "width x height" string:

     Image { sourceSize: "150x50" }

Or use the Qt.size() function:

     Image { sourceSize: Qt.size(150, 50) }

When integrating with C++, note that any QSize or QSizeF value passed into QML from C++ is automatically converted into a `size` value, and vice-versa. When a `size` value is passed to C++, it is automatically converted into a QSizeF value.
