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().

Since: 5.9

◆ addCacheableShaderFromSourceFile()

bool QOpenGLShaderProgram::addCacheableShaderFromSourceFile	(	QOpenGLShader::ShaderType	type,
		const QString &	fileName )

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

Unlike addShaderFromSourceFile(), 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 file has been read successfully, false if the file could not be opened or the normal, non-cached compilation of the shader has failed. 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 addShaderFromSourceFile().

◆ addShader()

bool QOpenGLShaderProgram::addShader ( QOpenGLShader * shader )

Adds a compiled shader to this shader program.

Definition at line 1526 of file qopenglshaderprogram.cpp.

◆ bind()

bool QOpenGLShaderProgram::bind ( )

Binds this shader program to the active QOpenGLContext and makes it the current shader program.

See also: disableAttributeArray(), setAttributeArray(), setAttributeValue(); setUniformValue()

Definition at line 2125 of file qopenglshaderprogram.cpp.

See also: disableAttributeArray(), setAttributeArray(), setAttributeValue(); setUniformValue()

Definition at line 2107 of file qopenglshaderprogram.cpp.

◆ hasOpenGLShaderPrograms()

bool QOpenGLShaderProgram::hasOpenGLShaderPrograms ( QOpenGLContext * context = nullptr )

static

Returns true if shader programs written in the OpenGL Shading Language (GLSL) are supported on this system; false otherwise.

The context is used to resolve the GLSL extensions. If context is \nullptr, then QOpenGLContext::currentContext() is used.

Definition at line 3691 of file qopenglshaderprogram.cpp.

◆ isLinked()

bool QOpenGLShaderProgram::isLinked ( ) const

Returns true if this shader program has been linked; false otherwise.

See also: link()

Definition at line 1347 of file qopenglshaderprogram.cpp.

◆ 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.

See also: addShader(), log()

Definition at line 1293 of file qopenglshaderprogram.cpp.

◆ log()

QString QOpenGLShaderProgram::log ( ) const

See also: bind()

Definition at line 1399 of file qopenglshaderprogram.cpp.

◆ removeAllShaders()

void QOpenGLShaderProgram::removeAllShaders ( )

See also: addShader(), removeShader()

Definition at line 1249 of file qopenglshaderprogram.cpp.

◆ removeShader()

		int	tupleSize,
		int	stride = 0 )

◆ setDefaultInnerTessellationLevels()

void QOpenGLShaderProgram::setDefaultInnerTessellationLevels ( const QList< float > & levels )

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. You should call this in your render function when needed, as QOpenGLShaderProgram will not apply this for you. This is purely a convenience function.; This function is only available with OpenGL >= 4.0 and is not supported with OpenGL ES 3.2.

◆ 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.
