## Properties

- vendorExtensionsEnabled : bool`(obsolete)`

## Property Documentation

vendorExtensionsEnabled : bool

This property is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This property controls the usage of non-standard OpenGL extensions like `GL_NV_path_rendering`.

The default value is `false`.

As of Qt 5.12 Shape.NvprRenderer is disabled by default and a uniform behavior, based on triangulating the path and generating QSGGeometryNode instances, is used regardless of the graphics card and drivers. To enable using vendor-specific path rendering approaches set the value to `true`. Depending on the platform and content, this can lead to improved performance. Setting the value to `true` is safe in any case since rendering falls back to the default method when the vendor-specific approach, such as `GL_NV_path_rendering`, is not supported at run time.

Changing the default value (false) is not recommended. In particular, support for Shape.NvprRenderer will not be available in future Qt versions. Applications experiencing rendering problems with the property set to true are advised to set it to false.
