## Member Type Documentation

### enum QStencilTestArguments::StencilFaceMode

This enumeration holds the values for stencil test arguments face modes

Constant | Value | Description
--- | --- | ---
`Qt3DRender::QStencilTestArguments::Front` | `0x0404` | Arguments are applied to front-facing polygons.
`Qt3DRender::QStencilTestArguments::Back` | `0x0405` | Arguments are applied to back-facing polygons.
`Qt3DRender::QStencilTestArguments::FrontAndBack` | `0x0408` | Arguments are applied to both front- and back-facing polygons.

### enum QStencilTestArguments::StencilFunction

Enumeration for the stencil function values

Constant | Value | Description
--- | --- | ---
`Qt3DRender::QStencilTestArguments::Never` | `0x0200` | Never pass stencil test
`Qt3DRender::QStencilTestArguments::Always` | `0x0207` | Always pass stencil test
`Qt3DRender::QStencilTestArguments::Less` | `0x0201` | Pass stencil test if fragment stencil is less than reference value
`Qt3DRender::QStencilTestArguments::LessOrEqual` | `0x0203` | Pass stencil test if fragment stencil is less than or equal to reference value
`Qt3DRender::QStencilTestArguments::Equal` | `0x0202` | Pass stencil test if fragment stencil is equal to reference value
`Qt3DRender::QStencilTestArguments::GreaterOrEqual` | `0x0206` | Pass stencil test if fragment stencil is greater than or equal to reference value
`Qt3DRender::QStencilTestArguments::Greater` | `0x0204` | Pass stencil test if fragment stencil is greater than reference value
`Qt3DRender::QStencilTestArguments::NotEqual` | `0x0205` | Pass stencil test if fragment stencil is not equal to reference value

## Property Documentation

### comparisonMask : uint

Holds the stencil test comparison mask. Default is all zeroes.

Access functions:

uint | comparisonMask() const
void | setComparisonMask(uint comparisonMask)

Notifier signal:

void | comparisonMaskChanged(uint comparisonMask)

### `[read-only]` faceMode : const StencilFaceMode

Holds the faces the arguments are applied to.

Access functions:

Qt3DRender::QStencilTestArguments::StencilFaceMode | faceMode() const

Notifier signal:

void | faceModeChanged(Qt3DRender::QStencilTestArguments::StencilFaceMode faceMode)

### referenceValue : int

Holds the stencil test reference value. Default is zero.

Access functions:

int | referenceValue() const
void | setReferenceValue(int referenceValue)

Notifier signal:

void | referenceValueChanged(int referenceValue)

### stencilFunction : StencilFunction

Holds the stencil test function. Default is Never.

Access functions:

Qt3DRender::QStencilTestArguments::StencilFunction | stencilFunction() const
void | setStencilFunction(Qt3DRender::QStencilTestArguments::StencilFunction stencilFunction)

Notifier signal:

void | stencilFunctionChanged(Qt3DRender::QStencilTestArguments::StencilFunction stencilFunction)
