详细描述

While languages like SPIR-V or the Metal Shading Language use traditional version numbers, shaders for other APIs can use slightly different versioning schemes. All those are mapped to a single version number in here, however. For HLSL, the version refers to the Shader Model version, like 5.0, 5.1, or 6.0. For GLSL an additional flag is needed to choose between GLSL and GLSL/ES.

Below is a list with the most common examples of shader versions for different graphics APIs:

• Vulkan (SPIR-V): 100
• OpenGL: 120, 330, 440, etc.
• OpenGL ES: 100 with GlslEs , 300 with GlslEs ，等。
• Direct3D: 50, 51, 60
• Metal: 12, 20

A default constructed QShaderVersion contains a version of 100 and no flags set.

注意： This is a RHI API with limited compatibility guarantees, see QShader 了解细节。

成员类型文档编制

enum QShaderVersion:: Flag
flags QShaderVersion:: Flags

Describes the flags that can be set.

常量	值	描述
QShaderVersion::GlslEs	0x01	Indicates that GLSL/ES is meant in combination with GlslShader

Flags 类型是 typedef 对于 QFlags <Flag>。它存储 Flag 值的 OR 组合。

[constexpr noexcept] QShaderVersion:: QShaderVersion ()

QShaderVersion:: QShaderVersion ( int v , QShaderVersion::Flags f = Flags())

Constructs a new QShaderVersion with version v and flags f .

QShaderVersion::Flags QShaderVersion:: flags () const

Returns the flags.

另请参阅 setFlags ().

void QShaderVersion:: setFlags ( QShaderVersion::Flags f )

Sets the flags f .

另请参阅 flags ().

void QShaderVersion:: setVersion ( int v )

Sets the shading language version to v .

另请参阅 version ().

int QShaderVersion:: version () const

Returns the version.

另请参阅 setVersion ().

[noexcept] bool operator!= (const QShaderVersion & lhs , const QShaderVersion & rhs )

返回 false if the values in the two QShaderVersion 对象 lhs and rhs 相等；否则返回 true .

[noexcept] bool operator< (const QShaderVersion & lhs , const QShaderVersion & rhs )

返回 true 若 lhs 小于 rhs .

Establishes a sorting order between the two QShaderVersion lhs and rhs .

[noexcept] bool operator== (const QShaderVersion & lhs , const QShaderVersion & rhs )

返回 true 若两 QShaderVersion 对象 lhs and rhs 相等。
