Constructor & Destructor Documentation

◆ Slider()

cloudViewer::visualization::gui::Slider::Slider ( Type type )

explicit

The only difference between INT and DOUBLE is that INT increments by 1.0 and coerces value to whole numbers.

◆ Draw()

Widget::DrawResult cloudViewer::visualization::gui::Slider::Draw ( const DrawContext & context )

overridevirtual

Draws the widget. If this is a Dear ImGUI widget, this is where the actual event processing happens. Return NONE if no action needs to be taken, REDRAW if the widget needs to be redrawn (e.g. its value changed), and RELAYOUT if the widget wishes to change size.
