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

SoType SoBoxHighlightRenderAction::getTypeId (void) const [virtual]

Returns the type identification of an action derived from a class inheriting SoAction. This is used for run-time type checking and 'downward' casting.

Usage example:

void bar(SoAction * action)
{
  if (action->getTypeId() == SoGLRenderAction::getClassTypeId()) {
    // safe downward cast, know the type
    SoGLRenderAction * glrender = (SoGLRenderAction *)action;
  }
  return; // ignore if not renderaction
}

For application programmers wanting to extend the library with new actions: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the pre-defined macros available through Inventor/nodes/SoSubAction.h: SO_ACTION_SOURCE, SO_ACTION_INIT_CLASS and SO_ACTION_CONSTRUCTOR.

For more information on writing Coin extensions, see the SoAction class documentation.

Returns the actual type id of an object derived from a class inheriting SoAction. Needs to be overridden in all subclasses.

Reimplemented from SoGLRenderAction.

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.

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.

const SoEnabledElementsList & SoBoxHighlightRenderAction::getEnabledElements (void) const [protected], [virtual]

Returns a list of the elements used by action instances of this class upon traversal operations.

Reimplemented from SoGLRenderAction.

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.

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.

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.

SoAction::apply(SoPath * 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]

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