GraphicsPipelineState Struct

struct QSGMaterialShader::GraphicsPipelineState

Describes state changes that the material wants to apply to the currently active graphics pipeline state. More...

This struct was introduced in Qt 5.14.

Public Types

enum BlendFactor { Zero, One, SrcColor, OneMinusSrcColor, DstColor, …, OneMinusSrc1Alpha }
flags ColorMask
enum ColorMaskComponent { R, G, B, A }
enum CullMode { CullNone, CullFront, CullBack }

Detailed Description

Unlike QSGMaterialShader, directly issuing state change commands with the underlying graphics API is not possible with QSGMaterialShader. This is mainly because the concept of individually changeable states is considered deprecated and not supported with modern graphics APIs.

Therefore, it is up to QSGMaterialShader to expose a data structure with the set of supported states, which the material can change in its updatePipelineState() implementation, if there is one. The scenegraph will then internally apply these changes to the active graphics pipeline state, then rolling them back as appropriate.
