Member Enumeration Documentation

◆ Type

enum open3d::visualization::gui::Slider::Type

Enumerator
INT
DOUBLE

Constructor & Destructor Documentation

◆ Slider()

open3d::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.

◆ ~Slider()

open3d::visualization::gui::Slider::~Slider ( )

Member Function Documentation

◆ CalcPreferredSize()

Size open3d::visualization::gui::Slider::CalcPreferredSize	(	const LayoutContext &	theme,
		const Constraints &	constraints ) const

overridevirtual

Reimplemented from open3d::visualization::gui::Widget.

◆ Draw()

Widget::DrawResult open3d::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.

Reimplemented from open3d::visualization::gui::Widget.

◆ GetDoubleValue()

double open3d::visualization::gui::Slider::GetDoubleValue ( ) const

Returns the value of the control as a double.

◆ GetIntValue()

int open3d::visualization::gui::Slider::GetIntValue ( ) const

Returns the value of the control as an integer.

◆ GetMaximumValue()

double open3d::visualization::gui::Slider::GetMaximumValue ( ) const

◆ GetMinimumValue()

double open3d::visualization::gui::Slider::GetMinimumValue ( ) const

◆ SetLimits()

void open3d::visualization::gui::Slider::SetLimits	(	double	min_value,
		double	max_value )

Sets the bounds for valid values of the widget. Values will be clamped to be within [minValue, maxValue].

◆ SetOnValueChanged()

void open3d::visualization::gui::Slider::SetOnValueChanged ( std::function< void(double)> on_value_changed )

Sets a function to call when the value changes because of user action.

◆ SetValue()

void open3d::visualization::gui::Slider::SetValue ( double val )

Sets the value of the control. Will not call onValueChanged, but the value will be clamped to [min, max].
