Detailed Description

Encapsulates the necessary information to create an OpenGL texture image.

QAbstractTextureImage should be used as the means of providing image data to a QAbstractTexture. It contains the necessary information: mipmap level, layer, cube face load at the proper place data into an OpenGL texture.

The actual data is provided through a QTextureImageDataGenerator that will be executed by Aspect jobs in the backend. QAbstractTextureImage should be subclassed to provide a functor and eventual additional properties needed by the functor to load actual data.

Note: : QAbstractTextureImage should never be shared. Expect crashes, undefined behavior at best if this rule is not respected.

Property Documentation

face : Qt3DRender::QAbstractTexture::CubeMapFace

Holds the cube map face of the texture image.

Note: The cube map face has a meaning only for TargetCubeMap and TargetCubeMapArray.

Access functions:

QAbstractTexture::CubeMapFace face() const
void setFace(QAbstractTexture::CubeMapFace face)

Notifier signal:

void faceChanged(QAbstractTexture::CubeMapFace face)

layer : int

Returns the layer of the texture image.

Access functions:

int layer() const
void setLayer(int layer)

Notifier signal:

void layerChanged(int layer)

mipLevel : int

Holds the mipmap level of the texture image.

Access functions:

int mipLevel() const
void setMipLevel(int level)

Notifier signal:

void mipLevelChanged(int mipLevel)

Member Function Documentation

QAbstractTextureImage::QAbstractTextureImage(Qt3DCore::QNode *parent = nullptr)

Constructs a new QAbstractTextureImage instance with parent as parent.

[pure virtual protected] Qt3DRender::QTextureImageDataGeneratorPtr QAbstractTextureImage::dataGenerator() const

Implement this method to return the QTextureImageDataGeneratorPtr, which will provide the data for the texture image.

[protected] void QAbstractTextureImage::notifyDataGeneratorChanged()

Triggers an update of the data generator that is sent to the backend.

[slot] void QAbstractTextureImage::setFace(QAbstractTexture::CubeMapFace face)

Sets the texture image face to face. face

Note: Setter function for property face.

See also face().

[slot] void QAbstractTextureImage::setLayer(int layer)

Sets the layer of a texture to layer. layer

Note: Setter function for property layer.

See also layer().

[slot] void QAbstractTextureImage::setMipLevel(int level)

Sets the mip level of a texture to level. level

Note: Setter function for property mipLevel.

See also mipLevel().
