Expand description

Various errors that methods can produce.

Variants§

§

Failed

The method failed for a miscellaneous reason.

§

UnsupportedOnThisPlatform

The platform doesn’t support this method.

§

Unimplemented

The platform supports this method in theory, but the functionality isn’t implemented yet.

§

UnsupportedGLType

The system doesn’t support the requested OpenGL API type (OpenGL or OpenGL ES).

§

UnsupportedGLProfile

The system doesn’t support the requested OpenGL compatibility profile for the supplied OpenGL version.

On some systems, like macOS, the compatibility profile is only supported on some GL versions.

§

UnsupportedGLVersion

The system doesn’t support the requested OpenGL API version.

§

PixelFormatSelectionFailed(WindowingApiError)

Choosing an OpenGL pixel format failed.

§

NoPixelFormatFound

The system couldn’t choose an OpenGL pixel format.

§

ContextCreationFailed(WindowingApiError)

The system couldn’t create an OpenGL context.

§

ContextDestructionFailed(WindowingApiError)

The system couldn’t destroy the OpenGL context.

§

MakeCurrentFailed(WindowingApiError)

The system couldn’t make the OpenGL context current or not current.

§

NoGLLibraryFound

The system OpenGL library couldn’t be located.

§

RequiredExtensionUnavailable

An extension necessary for this library to function isn’t supported.

§

GLFunctionNotFound

Looking up an OpenGL function address failed.

§

ExternalRenderTarget

This context renders to an externally-managed render target.

§

SurfaceAlreadyBound

A surface was already attached to this context.

§

NoAdapterFound

No suitable adapter could be found.

§

DeviceOpenFailed

The device couldn’t be opened.

§

SurfaceCreationFailed(WindowingApiError)

The system couldn’t create a surface.

§

SurfaceImportFailed(WindowingApiError)

The system couldn’t import a surface from another thread.

§

SurfaceTextureCreationFailed(WindowingApiError)

The system couldn’t create a surface texture from a surface.

§

PresentFailed(WindowingApiError)

The system couldn’t present a widget surface.

§

NoCurrentContext

A context couldn’t be created because there is no current context.

§

NoCurrentConnection

The current connection couldn’t be fetched because there is no current connection.

§

IncompatibleSurface

The surface was not created from this context.

§

IncompatibleContextDescriptor

The context descriptor is from a hardware device, but this is a software device, or vice versa.

§

IncompatibleContext

The context is from a hardware device, but this is a software device, or vice versa.

§

IncompatibleSharedContext

The shared context is not compatible for sharing.

§

IncompatibleSurfaceTexture

The surface texture is from a hardware device, but this is a software device, or vice versa.

§

NoWidgetAttached

The surface has no window attachment.

§

WidgetAttached

The surface has a window attachment.

§

InvalidNativeWidget

The native widget is invalid.

§

SurfaceDataInaccessible

The surface was not created with the CPU_READ_WRITE flag, so it cannot be accessed from the CPU.

§

SurfaceLockFailed

The surface could not be locked for CPU reading due to an OS error.

§

ConnectionFailed

A connection to the display server could not be opened.

§

ConnectionRequired

A connection to the window server is required to open a hardware device.

§

IncompatibleAdapter

The adapter type does not match the supplied connection.

§

IncompatibleNativeWidget

The native widget type does not match the supplied device.

§

IncompatibleRawDisplayHandle

The raw display handle is incompatible with this backend.

§

IncompatibleNativeContext

The native context does not match the supplied device.

§

IncompatibleNativeDevice

The native device does not match the supplied connection.
