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]

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

void SoLineHighlightRenderAction::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 SoLineHighlightRenderAction::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 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 (  unsigned short    pattern )

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

unsigned short 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.
