Class QAccelPlot::GradientTexture

ClassList > QAccelPlot > GradientTexture

Cached one-dimensional texture used by gradient materials.

• #include <GradientTexture.hpp>

Public Functions

Type	Name
	GradientTexture () = default
	GradientTexture (const GradientTexture &) = delete
void	commit (QSGMaterialShader::RenderState & state, QSGTexture ** texture) Commits the texture for the sampler being updated.
qint64	comparisonKey () const Returns the scene-graph comparison key for the uploaded texture, or zero when no texture exists.
GradientTexture &	operator= (const GradientTexture &) = delete
void	upload (QQuickWindow * window, const std::vector< GradientStopData > & stops) Updates the 256-sample texture when stops changed.
	~GradientTexture ()

Public Static Functions

Type	Name
const std::vector< GradientStopData > &	neutralStops () Returns a plain white ramp that keeps the sampler valid while a shader maps no values.
