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.
注意： This class has been deprecated in favor of QOpenGLShader .

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.
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
()
Deletes this shader. If the shader has been attached to a QGLShaderProgram object, then the actual shader will stay around until the QGLShaderProgram is destroyed.
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 ().
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.

true
if shader programs of 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。
返迴
true
if this shader has been compiled; false otherwise.
另請參閱 compileSourceCode () 和 compileSourceFile ().
Returns the errors and warnings that occurred during the last compile.

Returns the OpenGL identifier associated with this shader.
另請參閱 QGLShaderProgram::programId ().
Returns the type of this shader.
Returns the source code for this shader.
