詳細描述

The QOpenGLShader class allows OpenGL shaders to be compiled.

This class supports shaders written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).

QOpenGLShader and QOpenGLShaderProgram shelter the programmer from the details of compiling and linking vertex and fragment shaders.

enum QOpenGLShader:: ShaderTypeBit
flags QOpenGLShader:: ShaderType

This enum specifies the type of QOpenGLShader that is being created.

常量	值	描述
QOpenGLShader::Vertex	0x0001	Vertex shader written in the OpenGL Shading Language (GLSL).
QOpenGLShader::Fragment	0x0002	Fragment shader written in the OpenGL Shading Language (GLSL).
QOpenGLShader::Geometry	0x0004	Geometry shaders written in the OpenGL Shading Language (GLSL) based on the OpenGL core feature (requires OpenGL >= 3.2).
QOpenGLShader::TessellationControl	0x0008	Tessellation control shaders written in the OpenGL shading language (GLSL), based on the core feature (requires OpenGL >= 4.0).
QOpenGLShader::TessellationEvaluation	0x0010	Tessellation evaluation shaders written in the OpenGL shading language (GLSL), based on the core feature (requires OpenGL >= 4.0).
QOpenGLShader::Compute	0x0020	Compute shaders written in the OpenGL shading language (GLSL), based on the core feature (requires OpenGL >= 4.3).

The ShaderType type is a typedef for QFlags <ShaderTypeBit>. It stores an OR combination of ShaderTypeBit values.

QOpenGLShader:: QOpenGLShader ( QOpenGLShader::ShaderType type , QObject * parent = Q_NULLPTR)

構造新的 QOpenGLShader object of the specified type and attaches it to parent . If shader programs are not supported, QOpenGLShaderProgram::hasOpenGLShaderPrograms () 將返迴 false。

This constructor is normally followed by a call to compileSourceCode () 或 compileSourceFile ().

The shader will be associated with the current QOpenGLContext .

[虛擬] QOpenGLShader:: ~QOpenGLShader ()

Deletes this shader. If the shader has been attached to a QOpenGLShaderProgram object, then the actual shader will stay around until the QOpenGLShaderProgram 被銷毀。

bool QOpenGLShader:: compileSourceCode (const char * source )

設置 source code for this shader and compiles it. Returns true if the source was successfully compiled, false otherwise.

另請參閱 compileSourceFile ().

bool QOpenGLShader:: compileSourceCode (const QByteArray & source )

這是重載函數。

設置 source code for this shader and compiles it. Returns true if the source was successfully compiled, false otherwise.

另請參閱 compileSourceFile ().

bool QOpenGLShader:: compileSourceCode (const QString & source )

這是重載函數。

設置 source code for this shader and compiles it. Returns true if the source was successfully compiled, false otherwise.

另請參閱 compileSourceFile ().

bool QOpenGLShader:: compileSourceFile (const QString & fileName )

Sets the source code for this shader to the contents of fileName and compiles it. Returns true if the file could be opened and the source compiled, false otherwise.

另請參閱 compileSourceCode ().

[static] bool QOpenGLShader:: hasOpenGLShaders ( ShaderType type , QOpenGLContext * context = Q_NULLPTR)

返迴 true if shader programs of type type are supported on this system; false otherwise.

The context is used to resolve the GLSL extensions. If context is null, then QOpenGLContext::currentContext () 被使用。

bool QOpenGLShader:: isCompiled () const

返迴 true if this shader has been compiled; false otherwise.

另請參閱 compileSourceCode () 和 compileSourceFile ().

QString QOpenGLShader:: log () const

Returns the errors and warnings that occurred during the last compile.

另請參閱 compileSourceCode () 和 compileSourceFile ().

GLuint QOpenGLShader:: shaderId () const

Returns the OpenGL identifier associated with this shader.

另請參閱 QOpenGLShaderProgram::programId ().

QOpenGLShader::ShaderType QOpenGLShader:: shaderType () const

Returns the type of this shader.

QByteArray QOpenGLShader:: sourceCode () const

Returns the source code for this shader.
