Detailed Description

This class provides background for GUI elements.

This class is specifically made for rectangular (non-power of 2) textures, which may me procedurraly updated. It is hardwired to osg::TextureRectangle, no abstraction!

Constructor & Destructor Documentation

OSGVruiTextureRectBackground()

vrui::OSGVruiTextureRectBackground::OSGVruiTextureRectBackground

(

coTextureRectBackground *

background

)

Constructor.

Parameters

backgroundMaterial	normal color
highlightMaterial	highlighted color
disableMaterial	disabled color

coUIElement for color definition

~OSGVruiTextureRectBackground()

vrui::OSGVruiTextureRectBackground::~OSGVruiTextureRectBackground ( )

virtual

Destructor.

Member Function Documentation

createGeometry()

void vrui::OSGVruiTextureRectBackground::createGeometry ( )

virtual

create the geometry

Implements vrui::vruiUIElementProvider.

createSharedLists()

void vrui::OSGVruiTextureRectBackground::createSharedLists ( )

protected

create geometry elements shared by all OSGVruiTextureRectBackgrounds

createTexturesFromArrays()

void vrui::OSGVruiTextureRectBackground::createTexturesFromArrays ( uint *  normalImage, int  comp, int  ns, int  nt, int  nr  )

protected

create texture from arrays

createTexturesFromFiles()

void vrui::OSGVruiTextureRectBackground::createTexturesFromFiles ( )

protected

create texture from files

rescaleTexture()

void vrui::OSGVruiTextureRectBackground::rescaleTexture ( )

protected

rescales the texture; Texture coordinates are non-normalized, therefore they are set to ( 0, w, h, 0 ) see http://www.opengl.org/registry/specs/ARB/texture_rectangle.txt

resizeGeometry()

void vrui::OSGVruiTextureRectBackground::resizeGeometry ( )

virtual

Implements vrui::vruiUIElementProvider.

setEnabled()

void vrui::OSGVruiTextureRectBackground::setEnabled ( bool  en )

virtual

Set activation state of this background and all its children.

if this background is disabled, the color is always the disabled color, regardless of the highlighted state

Parameters

en	true = elements enabled

Reimplemented from vrui::vruiUIElementProvider.

setHighlighted()

void vrui::OSGVruiTextureRectBackground::setHighlighted ( bool  hl )

virtual

Reimplemented from vrui::vruiUIElementProvider.

update()

void vrui::OSGVruiTextureRectBackground::update ( )

virtual

removed REPEAT, since rectangular textures do not support repeat!

Reimplemented from vrui::vruiUIElementProvider.
