詳細描述

The QGLShader 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).

QGLShader and QGLShaderProgram shelter the programmer from the details of compiling and linking vertex and fragment shaders.

enum QGLShader:: ShaderTypeBit
flags QGLShader:: ShaderType

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

常量	值	描述
QGLShader::Vertex	0x0001	Vertex shader written in the OpenGL Shading Language (GLSL).
QGLShader::Fragment	0x0002	Fragment shader written in the OpenGL Shading Language (GLSL).
QGLShader::Geometry	0x0004	Geometry shaders written in the OpenGL Shading Language (GLSL), based on the GL_EXT_geometry_shader4 extension.

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

QGLShader:: QGLShader ( QGLShader::ShaderType type , QObject * parent = 0)

構造新的 QGLShader object of the specified type and attaches it to parent . If shader programs are not supported, QGLShaderProgram::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 QGLContext .

QGLShader:: QGLShader ( QGLShader::ShaderType type , const QGLContext * context , QObject * parent = 0)

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

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

The shader will be associated with context .

[虛擬] QGLShader:: ~QGLShader ()

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

bool QGLShader:: 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 QGLShader:: 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 QGLShader:: 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 QGLShader:: 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 QGLShader:: hasOpenGLShaders ( ShaderType type , const QGLContext * context = 0)

Returns 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 QGLContext::currentContext () 被使用。

該函數在 Qt 4.7 引入。

bool QGLShader:: isCompiled () const

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

另請參閱 compileSourceCode () 和 compileSourceFile ().

QString QGLShader:: log () const

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

另請參閱 compileSourceCode () 和 compileSourceFile ().

GLuint QGLShader:: shaderId () const

返迴 OpenGL identifier associated with this shader.

另請參閱 QGLShaderProgram::programId ().

QGLShader::ShaderType QGLShader:: shaderType () const

Returns the type of this shader.

QByteArray QGLShader:: sourceCode () const

Returns the source code for this shader.
