## 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() [1/2]

SoBoxHighlightRenderAction::SoBoxHighlightRenderAction | ( | void |  | ) |

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

## SoBoxHighlightRenderAction() [2/2]

SoBoxHighlightRenderAction::SoBoxHighlightRenderAction | ( | const SbViewportRegion & | viewportregion | ) |

Constructor, taking an explicit viewportregion to render.

## ~SoBoxHighlightRenderAction()

SoBoxHighlightRenderAction::~SoBoxHighlightRenderAction | ( | void |  | ) |

virtual

Destructor.

## Member Function Documentation

## getTypeId()

SoType SoBoxHighlightRenderAction::getTypeId | ( | void |  | ) | const

virtual

Returns the type identification of an object derived from a class inheriting SoAction. This is used for runtime type checking and "downward" casting.

Reimplemented from SoGLRenderAction.

## getClassTypeId()

SoType SoBoxHighlightRenderAction::getClassTypeId | ( | void |  | ) |

static

This static method returns the SoType object associated with objects of this class.

## addMethod()

void SoBoxHighlightRenderAction::addMethod | ( | const SoType | type,
|  | SoActionMethod | method )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

## enableElement()

void SoBoxHighlightRenderAction::enableElement | ( | const SoType | type,
|  | const int | stackindex )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

## getEnabledElements()

const SoEnabledElementsList & SoBoxHighlightRenderAction::getEnabledElements | ( | void |  | ) | const

protected virtual

Returns list of enabled elements.

Reimplemented from SoGLRenderAction.

## getClassEnabledElements()

SoEnabledElementsList * SoBoxHighlightRenderAction::getClassEnabledElements | ( | void |  | ) |

static protected

Returns list of enabled elements for this class. The enabledElements and methods variables are protected in the original OIV API. This is not such a good idea, since exposed static class member variables is a major grievance with regard to Win32 DLLs. This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

## getClassActionMethods()

SoActionMethodList * SoBoxHighlightRenderAction::getClassActionMethods | ( | void |  | ) |

static protected

Returns list of action methods for this class. The enabledElements and methods variables are protected in the original OIV API. This is not such a good idea, since exposed static class member variables is a major grievance with regard to Win32 DLLs. This function is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

## initClass()

void SoBoxHighlightRenderAction::initClass | ( | void |  | ) |

static

Initializes the runtime type system for this class, and sets up the enabled elements and action method list.

## apply() [1/3]

void SoBoxHighlightRenderAction::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.

## apply() [2/3]

void SoBoxHighlightRenderAction::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.

## apply() [3/3]

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.

See also
  SoAction::apply(SoPath * path)

Reimplemented from SoAction.

## setVisible()

void SoBoxHighlightRenderAction::setVisible | ( | const SbBool | visible | ) |

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

## isVisible()

SbBool SoBoxHighlightRenderAction::isVisible | ( | void |  | ) | const

Returns `TRUE` if highlighted boxes are visible otherwise `FALSE`.

## setColor()

void SoBoxHighlightRenderAction::setColor | ( | const SbColor & | color | ) |

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

## getColor()

const SbColor & SoBoxHighlightRenderAction::getColor | ( | void |  | ) |

Returns the rendering color of the highlighted boxes.

## setLinePattern()

void SoBoxHighlightRenderAction::setLinePattern | ( | unsigned short | pattern | ) |

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

## getLinePattern()

unsigned short SoBoxHighlightRenderAction::getLinePattern | ( | void |  | ) | const

Returns the line pattern used when drawing boxes.

## setLineWidth()

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.

## getLineWidth()

float SoBoxHighlightRenderAction::getLineWidth | ( | void |  | ) | const

Returns the line width used when drawing highlight boxes.

## Member Data Documentation

## hlVisible

SbBool SoBoxHighlightRenderAction::hlVisible

protected

Boolean which decides whether or not the highlights for selected nodes should be visible.
