Detailed Description

Base class for objects in OpenGL scene.

Constructor & Destructor Documentation

LangmuirView::SceneObject::SceneObject ( LangmuirViewer &  viewer, QObject *  parent = 0  )

explicit

create the SceneObject

Parameters

viewer	the viewer
parent	QObject this belongs to

Member Function Documentation

virtual void LangmuirView::SceneObject::draw ( )

protectedvirtual

perform OpenGL drawing operations

Reimplemented in LangmuirView::PointCloud, LangmuirView::Light, LangmuirView::Box, LangmuirView::Mesh, LangmuirView::Axis, and LangmuirView::Grid.

virtual void LangmuirView::SceneObject::init ( )

protectedvirtual

initialize object

Explicitly call this in derived class constructor.

Reimplemented in LangmuirView::PointCloud, LangmuirView::Light, LangmuirView::Box, LangmuirView::Mesh, LangmuirView::Axis, LangmuirView::CornerAxis, and LangmuirView::Grid.

bool LangmuirView::SceneObject::isVisible

(

)

true if object is drawn

virtual void LangmuirView::SceneObject::makeConnections ( )

virtualslot

make signal/slot connections

virtual void LangmuirView::SceneObject::postDraw ( )

protectedvirtual

perform OpenGL drawing operations after draw()

Reimplemented in LangmuirView::CornerAxis.

virtual void LangmuirView::SceneObject::preDraw ( )

protectedvirtual

perform OpenGL drawing operations before draw()

Reimplemented in LangmuirView::CornerAxis.

void LangmuirView::SceneObject::render

(

)

calls OpenGL drawing commands.

Use this inside the paintGL() or draw() functions of the main OpenGL widget.

void LangmuirView::SceneObject::setVisible ( bool  draw = true )

slot

set the visibility

Parameters

draw	true if object is to be drawn

void LangmuirView::SceneObject::toggleVisible ( )

slot

toggle visibility

void LangmuirView::SceneObject::visibleChanged ( bool  drawn )

signal

signal that the visibility has changed

Parameters

drawn

true if object is visible

Member Data Documentation
