- 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) constReturns 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).

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.

SoLineHighlightRenderAction::SoLineHighlightRenderAction (void)Default constructor. Note: passes a default SbViewportRegion to the parent constructor.

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 * root) [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.
References SoNode::getClassTypeId(), SbPList::getLength(), SoSelection::getList(), SoSelection::getNumSelected(), SoPath::getTail(), SoBase::getTypeId(), hlVisible, and SoType::isDerivedFrom().
Referenced by apply().
void SoLineHighlightRenderAction::apply (SoPath * path) [virtual]Applies the action to the parts of the graph defined by path.
Note that an SoPath will also contain all nodes that may influence e.g. geometry nodes in the path. So for instance applying an SoGLRenderAction on an SoPath will render that path as expected in the view, where geometry will get its materials, textures, and other appearance settings correctly.
If the path ends in an SoGroup node, the action will also traverse the tail node's children.
Reimplemented from SoAction.
References apply().
void SoLineHighlightRenderAction::apply (const SoPathList & pathlist, SbBool obeysrules = 0) [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.

- SoAction::apply(SoPath * path)
Reimplemented from SoAction.

void SoLineHighlightRenderAction::setVisible (const SbBool visible)Sets if highlight wireframes should be visible when rendering. Defaults to TRUE.
References hlVisible.
SbBool SoLineHighlightRenderAction::isVisible (void) constReturn if selection wireframes should be visible.
References hlVisible.
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) constReturns 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) constReturns the line width used when drawing wireframe.
Member Data Documentation
SoLineHighlightRenderAction::hlVisible [protected]Boolean which decides whether or not the highlights for selected nodes should be visible.
