Constructor & Destructor Documentation

◆ QOpenGLShaderProgram()

QOpenGLShaderProgram::QOpenGLShaderProgram ( QObject * parent = nullptr )

explicit

Constructs a new shader program and attaches it to parent.

The program will be invalid until addShader() is called.

The shader program will be associated with the current QOpenGLContext.

◆ ~QOpenGLShaderProgram()

QOpenGLShaderProgram::~QOpenGLShaderProgram ( )

Deletes this shader program.

Member Function Documentation

◆ addCacheableShaderFromSourceCode() [1/3]

bool QOpenGLShaderProgram::addCacheableShaderFromSourceCode	(	QOpenGLShader::ShaderType	type,
		const char *	source )

Registers the shader of the specified type and source to this program.

Unlike addShaderFromSourceCode(), this function does not perform compilation. Compilation is deferred to link(), and may not happen at all, because link() may potentially use a program binary from Qt's shader disk cache. This will typically lead to a significant increase in performance.

Returns: true if the shader has been registered or, in the non-cached case, compiled successfully; false if there was an error. The compilation error messages can be retrieved via log().

When the disk cache is disabled, via Qt::AA_DisableShaderDiskCache for example, or the OpenGL context has no support for context binaries, calling this function is equivalent to addShaderFromSourceCode().

◆ link()

bool QOpenGLShaderProgram::link ( )

virtual

Links together the shaders that were added to this program with addShader().

Returns true if the link was successful or false otherwise. If the link failed, the error messages can be retrieved with log().

Subclasses can override this function to initialize attributes and uniform variables for use in specific shader programs.

If the shader program was already linked, calling this function again will force it to be re-linked.

When shaders were added to this program via addCacheableShaderFromSourceCode() or addCacheableShaderFromSourceFile(), program binaries are supported, and a cached binary is available on disk, actual compilation and linking are skipped. Instead, link() will initialize the program with the binary blob via glProgramBinary(). If there is no cached version of the program or it was generated with a different driver version, the shaders will be compiled from source and the program will get linked normally. This allows seamless upgrading of the graphics drivers, without having to worry about potentially incompatible binary formats.

Sets the default outer tessellation levels to be used by the tessellation primitive generator in the event that the tessellation control shader does not output them to levels.

For more details on OpenGL and Tessellation shaders see \l{OpenGL Tessellation Shaders}.

The levels argument should be a QList consisting of 2 floats. Not all of the values make sense for all tessellation modes. If you specify a vector with fewer than 2 elements, the remaining elements will be given a default value of 1.

Note: This modifies global OpenGL state and is not specific to this QOpenGLShaderProgram instance.

◆ setPatchVertexCount()

void QOpenGLShaderProgram::setPatchVertexCount ( int count )

Use this function to specify to OpenGL the number of vertices in a patch to count.

A patch is a custom OpenGL primitive whose interpretation is entirely defined by the tessellation shader stages. Therefore, calling this function only makes sense when using a QOpenGLShaderProgram containing tessellation stage shaders. When using OpenGL tessellation, the only primitive that can be rendered with {glDraw*()} functions is {GL_PATCHES}.

This is equivalent to calling glPatchParameteri(GL_PATCH_VERTICES, count).

Note: This modifies global OpenGL state and is not specific to this QOpenGLShaderProgram instance. You should call this in your render function when needed, as QOpenGLShaderProgram will not apply this for you. This is purely a convenience function.

◆ setUniformValueArray() [18/30]

void QOpenGLShaderProgram::setUniformValueArray	(	int	location,
		const GLuint *	values,

Sets the uniform variable array at location in the current context to the count elements of values.

This overload should be used when setting an array of sampler values.

Note: This function is not aware of unsigned int support in modern OpenGL versions and therefore treats values as a GLint and calls glUniform1iv.
