Detailed Description

A ParamWidget that represents an integer.

Increases by 1 each time it is clicked. When maxValue is reached, the next click resets to minValue. In momentary mode, the value is instead set to maxValue when the mouse is held and minValue when released.

Member Function Documentation

◆ initParamQuantity()

void rack::app::Switch::initParamQuantity ( )
overridevirtual

Configures ParamQuantity properties based on the type of ParamWidget.

This seems a bit hacky, but it's easier than requiring plugin developers to set ParamQuantity::randomizeEnabled, etc.

Reimplemented from rack::app::ParamWidget.

◆ step()

void rack::app::Switch::step ( )
overridevirtual

Advances the module by one frame.

Reimplemented from rack::app::ParamWidget.

◆ onDoubleClick()

void rack::app::Switch::onDoubleClick ( const DoubleClickEvent e)
overridevirtual

Reimplemented from rack::app::ParamWidget.

◆ onDragStart()

void rack::app::Switch::onDragStart ( const DragStartEvent e)
overridevirtual

Reimplemented from rack::widget::Widget.

◆ onDragEnd()

void rack::app::Switch::onDragEnd ( const DragEndEvent e)
overridevirtual

Reimplemented from rack::widget::Widget.
