Constructor & Destructor Documentation

ColorSlider ( Type  type = HORIZONTAL,
float  min = 0.0f,
float  max = 100.0f,
float  value = 0.0f,
float  step = 1.0f 
)

Constructor.

Parameters
typeOrientation (HORIZONTAL or VERTICAL).
minMinimum value.
maxMaximum value.
valueInitial value.
stepAmount the value is rounded to, also added or removed by the mouse wheel.

Member Function Documentation

float4 colorAt ( float  ratio) const

Returns the color of the gradient at a given position, in [0.0, 1.0]

auto getArrow ( ) const
inline

Returns the arrow the user drags to change the value

const auto& getColors ( ) const
inline

Returns the colors the gradient is interpolated between, evenly spaced

auto getSteps ( ) const
inline

Returns the number of strips the gradient is drawn with

const auto& getTrackRect ( ) const
inline

Returns the rectangle the gradient is drawn in, next to the arrow

void setColors ( const std::vector< float4 > &  colors)

Changes the colors the gradient is interpolated between, evenly spaced. The first one is displayed at the minimum value, the last one at the maximum.

void setResources ( const std::string &  resArrow)

Sets the UI resources of the widgets created by the slider, hiding the three resources of a Slider : the gradient replaces the track & the fill.

Parameters
resArrowResource for the arrow.
void setSteps ( uint32  steps)

Changes the number of strips the gradient is drawn with

void update ( )
overrideprotectedvirtual

Places the track, the fill & the grip for the current value & size.

Reimplemented from lysa::ui::Slider::update()

Member Data Documentation

constexpr float DEFAULT_ARROW_SIZE {10.0f}
staticconstexpr

Default size of the arrow, in square units.

constexpr uint32 DEFAULT_STEPS {64}
