## Function Documentation

### `[deprecated in 6.9]` int qDefaultSurfaceFormat(bool antialias)

This function is deprecated since 6.9. We strongly advise against using it in new code.

Use QQuick3D::idealSurfaceFormat()

This convenience function can be used to create a custom surface format suitable for use by Qt Graphs graphs.

The antialias parameter specifies whether or not antialiasing is activated.

Give the surface format returned by this function to the graph constructor (C++) or set it as the window format for QQuickView (QML) before calling `show()` on it.

For example, disable antialiasing on C++ application:

     #include <QtGraphs/qutils.h>

     // ...

     QSurfaceFormat::setDefaultFormat(qDefaultSurfaceFormat(true));

For example, enable antialiasing for direct rendering modes on QML application:

     #include <QtGraphs/qutils.h>

     // ...

     QQuickView viewer;
     viewer.setFormat(qDefaultSurfaceFormat(true));
