Detailed Description

This class provides a basic 3D slider, which is based on a texture mapped tickmark field and a round slider position indicator.

Constructor & Destructor Documentation

OSGVruiSlider()

vrui::OSGVruiSlider::OSGVruiSlider

(

coSlider *

slider

)

~OSGVruiSlider()

vrui::OSGVruiSlider::~OSGVruiSlider ( )

virtual

Destructor.

The slider is removed from all parents to which it is attached.

Member Function Documentation

createGeometry()

void vrui::OSGVruiSlider::createGeometry ( )

virtual

Implements vrui::vruiUIElementProvider.

resizeGeometry()

void vrui::OSGVruiSlider::resizeGeometry ( )

virtual

This method is called whenever the GUI element containing the slider changes its size.

The method resizes dial and position indicator and recomputes the respective Geodes.

Implements vrui::vruiUIElementProvider.

update()

void vrui::OSGVruiSlider::update ( )

virtual

Reimplemented from vrui::vruiUIElementProvider.

updateDial()

void vrui::OSGVruiSlider::updateDial ( )

protected

This routine regenerates the texture mapping for the dial.

updateSlider()

void vrui::OSGVruiSlider::updateSlider ( )

protected

This routine resets the location of the position indicator according to the current slider value.
