When used with - vertex buffers, the data pointer may be an offset into the vertex - buffer instead. - - QGLAttributeValue encapsulates these four values so that they can - be easily manipulated as a set during OpenGL painting operations. - Constructors are provided for converting QArray and - QCustomDataArray objects into an attribute value. - - Because the data() value is a raw pointer to arbitrary memory, - care should be taken that the memory remains valid until the - QGLAttributeValue is no longer required. - - \sa QGLAttributeDescription, QArray, QCustomDataArray -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue() - - Constructs a null attribute value with default parameters of - tupleSize(), and stride() set to zero, type() set to GL_FLOAT, - and data() set to null. - - \sa isNull() -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QArray<float>& array) - - Constructs an attribute value that refers to the contents of \a array, - setting tupleSize() to 1, type() to GL_FLOAT, and stride() to zero. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QArray<QVector2D>& array) - - Constructs an attribute value that refers to the contents of \a array, - setting tupleSize() to 2, type() to GL_FLOAT, and stride() to zero. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QArray<QVector3D>& array) - - Constructs an attribute value that refers to the contents of \a array, - setting tupleSize() to 3, type() to GL_FLOAT, and stride() to zero. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QArray<QVector4D>& array) - - Constructs an attribute value that refers to the contents of \a array, - setting tupleSize() to 4, type() to GL_FLOAT, and stride() to zero. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QArray<QColor4ub>& array) - - Constructs an attribute value that refers to the contents of \a array, - setting tupleSize() to 4, type() to GL_UNSIGNED_BYTE, and stride() to zero. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ - -/*! - Constructs an attribute value that refers to the contents of \a array. - The tupleSize() and type() of the attribute value will be set according - to the QCustomDataArray::elementType() of \a array. - - The \a array must not be destroyed or modified until the attribute - value is no longer required. -*/ -QGLAttributeValue::QGLAttributeValue(const QCustomDataArray& array) - : m_tupleSize(0), m_type(GL_FLOAT), m_stride(0) - , m_data(array.data()), m_count(array.count()) -{ - switch (array.elementType()) { - case QCustomDataArray::Float: - m_tupleSize = 1; - break; - case QCustomDataArray::Vector2D: - m_tupleSize = 2; - break; - case QCustomDataArray::Vector3D: - m_tupleSize = 3; - break; - case QCustomDataArray::Vector4D: - m_tupleSize = 4; - break; - case QCustomDataArray::Color: - m_tupleSize = 4; - m_type = GL_UNSIGNED_BYTE; - break; - } -} - -/*! - \fn QGLAttributeValue::QGLAttributeValue(int tupleSize, GLenum type, int stride, const void *data, int count) - - Constructs an attribute value with the fields \a tupleSize, \a type, - \a stride, \a data, and \a count. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(int tupleSize, GLenum type, int stride, int offset, int count) - - Constructs an attribute value with the fields \a tupleSize, \a type, - \a stride, \a offset, and \a count. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QGLAttributeDescription& description, const void *data, int count) - - Constructs an attribute value with the supplied \a description, - \a data, and \a count. -*/ - -/*! - \fn QGLAttributeValue::QGLAttributeValue(const QGLAttributeDescription& description, int offset, int count) - - Constructs an attribute value with the supplied \a description, - \a offset, and \a count. -*/ - -/*! - \fn bool QGLAttributeValue::isNull() const - - Returns true if tupleSize() is zero, which indicates an unset - attribute value; false otherwise. - - Note: it is possible for data() to be null, but isNull() returns true. - This can happen when data() is actually a zero offset into a - vertex buffer. -*/ - -/*! - \fn QGLAttributeDescription QGLAttributeValue::description(QGL::VertexAttribute attribute) const - - Returns the description of this value, tagged with \a attribute. - - \sa type() -*/ - -/*! - \fn GLenum QGLAttributeValue::type() const - - Returns the component type for this attribute value.
