Detailed Description

The SoLineHighlightRenderAction class renders selections with line highlighting.

See the documentation of SoBoxHighlightRenderAction.

The only difference between SoBoxHighlightRenderAction and this action is that this action renders highlights by superposing a wireframe image onto each shape instead of the bounding box when drawing the highlight.

SoBoxHighlightRenderAction, SoSelection


Constructor & Destructor Documentation

SoLineHighlightRenderAction::SoLineHighlightRenderAction void   
 

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

SoLineHighlightRenderAction::SoLineHighlightRenderAction const SbViewportRegion   viewportregion
 

Constructor, taking an explicit viewportregion to render.

SoLineHighlightRenderAction::~SoLineHighlightRenderAction   [virtual]
 

The destructor.


Member Function Documentation

void SoLineHighlightRenderAction::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 SoLineHighlightRenderAction::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 SoLineHighlightRenderAction::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 SoLineHighlightRenderAction::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 SoLineHighlightRenderAction::setVisible const SbBool    visible
 

Sets if highlight wireframes should be visible when rendering. Defaults to TRUE.

SbBool SoLineHighlightRenderAction::isVisible void    const
 

Return if selection wireframes should be visible.

void SoLineHighlightRenderAction::setColor const SbColor   color
 

Sets the color of the wireframes. Defaults to red.

const SbColor & SoLineHighlightRenderAction::getColor void   
 

Returns color of selection wireframes.

void SoLineHighlightRenderAction::setLinePattern uint16_t    pattern
 

Sets the line pattern used when drawing wireframes. Defaults to 0xffff (i.e. full, unstippled lines).

uint16_t SoLineHighlightRenderAction::getLinePattern void    const
 

Returns line pattern used when drawing wireframe.

void SoLineHighlightRenderAction::setLineWidth const float    width
 

Sets the line width used when drawing wireframe. Defaults to 3 (measured in screen pixels).

float SoLineHighlightRenderAction::getLineWidth void    const
 

Returns the line width used when drawing wireframe.


Member Data Documentation

SoLineHighlightRenderAction::hlVisible [protected]
