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 upon 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]
 

Applies the action to the scene graph rooted at root.

Note that you should not apply an action to a node with a zero reference count. The behavior in that case is undefined.

Reimplemented from SoAction.

void SoBoxHighlightRenderAction::apply SoPath   path [virtual]
 

Applies the action to the parts of the graph defined by path.

If the path ends in an SoGroup node, the action will also traverse the tail node's children.

Reimplemented from SoAction.

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

Applies action to the graphs defined by pathlist. If obeysrules is set to TRUE, pathlist must obey the following four conditions (which is the case for path lists returned from search actions for non-group nodes and path lists returned from picking actions):

All paths must start at the same head node. All paths must be sorted in traversal order. The paths must be unique. No path can continue through the end point of another path.

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.


Member Data Documentation

SoBoxHighlightRenderAction::hlVisible [protected]
