Detailed Description¶
This class supports shaders written in the OpenGL Shading Language (GLSL) and in the OpenGL/ES Shading Language (GLSL/ES).
QGLShader
andQGLShaderProgram
shelter the programmer from the details of compiling and linking vertex and fragment shaders.Note
This class has been deprecated in favor of
QOpenGLShader
.See also

QGLShader
(type[, parent=None])¶ QGLShader(type, context[, parent=None])
- param type
ShaderType
- param parent
QObject
- param context
Constructs a new
QGLShader
object of the specifiedtype
and attaches it toparent
. If shader programs are not supported,hasOpenGLShaderPrograms()
will return false.This constructor is normally followed by a call to
compileSourceCode()
orcompileSourceFile()
.The shader will be associated with the current
QGLContext
.See also

that is being created.Constant
Description
QGLShader.Vertex
Vertex shader written in the OpenGL Shading Language (GLSL).
QGLShader.Fragment
Fragment shader written in the OpenGL Shading Language (GLSL).
QGLShader.Geometry

compileSourceCode
(source)¶ - Parameters
source –
QByteArray
- Return type
bool
-
PySide2.QtOpenGL.QGLShader.
compileSourceCode
(source) - Parameters
source – unicode
- Return type
bool
-
PySide2.QtOpenGL.QGLShader.
compileSourceCode
(source) - Parameters
source – str
- Return type
bool
Sets the
source
code for this shader and compiles it. Returnstrue
if the source was successfully compiled, false otherwise.See also
-
PySide2.QtOpenGL.QGLShader.
compileSourceFile
(fileName)¶ - Parameters
fileName – unicode
- Return type
bool
Sets the source code for this shader to the contents of
fileName
and compiles it. Returnstrue
if the file could be opened and the source compiled, false otherwise.See also

PySide2.QtOpenGL.QGLShader.
hasOpenGLShaders
(type[, context=None])¶ - Parameters
type –
ShaderType
context –
QGLContext
- Return type
bool
Returns
true
if shader programs of typetype
are supported on this system; false otherwise.The
context
is used to resolve the GLSL extensions. Ifcontext
is null, thencurrentContext()
is used.

log
()¶ - Return type
unicode
Returns the errors and warnings that occurred during the last compile.

()¶ - Return type
QByteArray
Returns the source code for this shader.
