Detailed Description

The SoBoxHighlightRenderAction class renders the scene with highlighted boxes around selections.

This action performs the same tasks as its parent class, SoGLRenderAction, with the added ability to render highlighted bounding boxes around geometry in selected nodes. This is a simple but convenient way of giving feedback to the user upo interaction with the scene graph.

To have the highlighting actually happen (and to be able to automatically "select" nodes by picking with the mouse cursor), you need to use SoSelection nodes in place of group nodes.

Constructor & Destructor Documentation

SoBoxHighlightRenderAction::SoBoxHighlightRenderAction (  void )

Default constructor. Note: passes a default SbViewportRegion to the parent constructor.

SoBoxHighlightRenderAction::SoBoxHighlightRenderAction (  const SbViewportRegion & viewportregion )

Constructor, taking an explicit viewportregion to render.

SoBoxHighlightRenderAction::~SoBoxHighlightRenderAction (  void )  [virtual]

Destructor.

Member Function Documentation

void SoBoxHighlightRenderAction::initClass (  void )  [static]

Initializes the run-time type system for this class, and sets up the enabled elements and action method list. Reimplemented from SoGLRenderAction.

void SoBoxHighlightRenderAction::apply (  SoNode * node )  [virtual]

Overloaded to add highlighting after the "ordinary" rendering. Reimplemented from SoAction.

void SoBoxHighlightRenderAction::apply (  SoPath * path )  [virtual]

This method will just call the SoGLRenderAction::apply() method (so no highlighting will be done). It has been overloaded to avoid confusing the compiler, which typically want to see either all or none of the apply() methods overloaded. Reimplemented from SoAction.

void SoBoxHighlightRenderAction::apply (  const SoPathList & pathlist, SbBool obeysrules = FALSE )  [virtual]

This method will just call the SoGLRenderAction::apply() method (so no highlighting will be done). It has been overloaded to avoid confusing the compiler, which typically want to see either all or none of the apply() methods overloaded. Reimplemented from SoAction.

void SoBoxHighlightRenderAction::setVisible (  const SbBool visible )

Sets if highlighted boxes should be visible when rendering. Defaults to TRUE.

SbBool SoBoxHighlightRenderAction::isVisible (  void )  const

Return if highlighted boxes are to be visible.

void SoBoxHighlightRenderAction::setColor (  const SbColor & color )

Sets the color for the highlighted boxes. Defaults to completely red.

const SbColor & SoBoxHighlightRenderAction::getColor (  void )

Returns rendering color of the highlighted boxes.

void SoBoxHighlightRenderAction::setLinePattern (  unsigned short pattern )

Sets the line pattern used for the highlighted boxes. Defaults to 0xffff (i.e. drawn with no stipples).

unsigned short SoBoxHighlightRenderAction::getLinePattern (  void )  const

Returns line pattern used when drawing boxes.

void SoBoxHighlightRenderAction::setLineWidth (  const float width )

Sets the line width used when drawing boxes, in screen pixels (as for all OpenGL rendering). Defaults to 3.

float SoBoxHighlightRenderAction::getLineWidth (  void )  const

Returns the line width used when drawing highlight boxes.
