Detailed Description

Control to display a slider for double value input.

Member Function Documentation

◆ setCurveMidpoint()

void AzQtComponents::SliderDouble::setCurveMidpoint ( double midpoint )

Sets a non-linear scale power curve. Defaults to 0.5, which is a linear curve. Lowering or raising the midpoint value will shift the scale to have higher precision at the lower or higher end, respectively.

◆ valueChanged

void AzQtComponents::SliderDouble::valueChanged ( double value )

signal

Triggered when the slider's value has been changed. The tracking setting determines whether this signal is emitted during user interaction.

Property Documentation

◆ curveMidpoint

double AzQtComponents::SliderDouble::curveMidpoint

readwrite

An optional non-linear scale setting using a power curve. Defaults to 0.5, which is a linear curve. Lowering or raising the midpoint value will shift the scale to have higher precision at the lower or higher end, respectively.
