Member Function Documentation

void SoVRMLText::initClass void    [static]
 

Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system.

Reimplemented from SoVRMLGeometry.

void SoVRMLText::GLRender SoGLRenderAction   action [virtual]
 

Action method for the SoGLRenderAction.

This is called during rendering traversals. Nodes influencing the rendering state in any way or who wants to throw geometry primitives at OpenGL overrides this method.

Reimplemented from SoShape.

void SoVRMLText::getPrimitiveCount SoGetPrimitiveCountAction   action [virtual]
 

Action method for the SoGetPrimitiveCountAction.

Calculates the number of triangle, line segment and point primitives for the node and adds these to the counters of the action.

Nodes influencing how geometry nodes calculates their primitive count also overrides this method to change the relevant state variables.

Reimplemented from SoShape.

void SoVRMLText::notify SoNotList   list [virtual]
 

Notifies all auditors for this instance when changes are made.

Reimplemented from SoVRMLGeometry.

SoChildList * SoVRMLText::getChildren void    const [virtual]
 

Returns list of children for this node.

Reimplemented from SoVRMLGeometry.

void SoVRMLText::computeBBox SoAction   action,
SbBox3f   box,
SbVec3f   center
[protected, virtual]
 

Implemented by SoShape subclasses to let the SoShape superclass know the exact size and weighted center point of the shape's bounding box.

The bounding box and center point should be calculated and returned in the local coordinate system.

The method implements action behavior for shape nodes for SoGetBoundingBoxAction. It is invoked from SoShape::getBoundingBox(). (Subclasses should not override SoNode::getBoundingBox().)

The box parameter sent in is guaranteed to be an empty box, while center is undefined upon function entry.

Implements SoShape.

void SoVRMLText::generatePrimitives SoAction   action [protected, virtual]
 

The method implements action behavior for shape nodes for SoCallbackAction. It is invoked from SoShape::callback(). (Subclasses should not override SoNode::callback().)

The subclass implementations uses the convenience methods SoShape::beginShape(), SoShape::shapeVertex(), and SoShape::endShape(), with SoDetail instances, to pass the primitives making up the shape back to the caller.

Implements SoShape.


Member Data Documentation

SoMFString SoVRMLText::string
 

The strings. Empty by default.

SoSFNode SoVRMLText::fontStyle
 

Can contain an SoVRMLFontStyle node.

SoSFFloat SoVRMLText::maxExtent
 

Maximum object space extent of longest string.

SoMFFloat SoVRMLText::length
 

Length of each string in the local coordinate system.
