## QSkinny - Using QSkinny and QML

Combining QSkinny and QML is possible: Since both QML elements and
QSkinny controls derive from `QQuickItem`, they can be combined and
arranged in a common app. The
https://github.com/uwerat/qskinny/tree/master/examples/buttons[QSkinny
buttons example] shows how QSkinny controls can be used from QML.

When using a QSkinny control, all the methods exposed as either properties,
slots or invokables can be used in QML. For example, the QSkinny control
`QskLinearBox` defines the following properties:

**CMakeLists.txt**

```cmake
target_link_libraries(myapp PRIVATE 
    ...
    Qsk::QmlExport)
...
```

```cpp
class QSK_EXPORT QskLinearBox : public QskIndexedLayoutBox
{
    Q_PROPERTY( Qt::Orientation orientation READ orientation WRITE setOrientation NOTIFY orientationChanged FINAL )
    Q_PROPERTY( qreal spacing READ spacing WRITE setSpacing RESET resetSpacing NOTIFY spacingChanged FINAL )
    ...
};
```

The `QskLinearBox` class is registered to QML as `Qsk.LinearBox` via
Qt’s `qmlRegisterType`, so the exposed properties `orientation` and
`spacing` can be used like this:

```
Qsk.LinearBox
{
    orientation: Qt.Horizontal
    spacing: 10

    // here define elements inside the box
    ...
}
```

The full Buttons example is depicted below.

For more information on using C++ classes from QML, see the article about exposing attributes of {cpp} types to QML in the
[Qt documentation](https://doc.qt.io/qt-5/qtqml-cppintegration-exposecppattributes.html).
