Struct QAccelPlot::CurveHitTestParams

ClassList > QAccelPlot > CurveHitTestParams

All inputs required for a contains() hit-test, bundled to reduce parameter count.

• #include <CurveRendererParams.hpp>

Public Attributes

Type	Name
const std::vector< CurveChunk > &	chunks Precomputed chunk bounding boxes.
CurveDataView	data Interleaved XY source data without precision loss.
qreal	height Height of the curve item in pixels.
qreal	hitThreshold Hit distance threshold in pixels.
bool	nonPositiveXInvalid Whether non-positive X values are invalid data points (X axis uses log scale).
bool	nonPositiveYInvalid Whether non-positive Y values are invalid data points (Y axis uses log scale).
int	pointCount Number of leading points in data to test; later points are never hit.
StepMode	stepMode = {StepMode::None} How the line joins consecutive data points.
qreal	width Width of the curve item in pixels.
Axis *	xAxis Horizontal axis for coordinate mapping.
Axis *	yAxis Vertical axis for coordinate mapping.
