| When applied, an action may reference nodes or create objects (e.g. | |
| virtual void | invalidateState () |
| Invalidates the current traversal state in the action, forcing it to be recreated when the action is next applied. | |

| This function resets the continue action flag. | |
| void | useAlternateRep (const SbBool enable) |
| Tell the action to use alternate representations during traversal when available. | |
| SbBool | isUsingAlternateRep () const |
| Returns TRUE if current action is using alternate representations. | |
| void | setSceneManager (SoSceneManager *mgr) |
| Set the scene manager associated with this action (if any ). | |
| SoSceneManager * | getSceneManager () const |
| Return the SoSceneManager associated with this action. | |
| virtual void | forwardTraversal (SoNode *node) |
| Traverse a node that is not part of the current scenegraph. | |
| virtual void | forwardTraversal (SoPath *path) |
| Traverse a path that is not part of the current scenegraph. | |
| DistribMode | getDistribMode () const |
| Returns the distribution mode of this action across a cluster (ScaleViz-Cluster only). | |
| AppliedCode | getWhatAppliedTo () const |
| Returns code indicating what action is being applied to. | |
| SoNode * | getNodeAppliedTo () const |
| Returns the node the action is being applied to. | |
| SoPath * | getPathAppliedTo () const |

| const SoPathList * | getOriginalPathListAppliedTo () const |
| Returns the original path list the action is being applied to. | |
| SbBool | isLastPathListAppliedTo () const |
| Returns TRUE if the current list is the last one from the original. | |
| PathCode | getPathCode (int &numIndices, const int *&indices) |
| Returns path code based on where current node (the node at the end of the current path) lies with respect to the path(s) the action is being applied to. | |
| PathCode | getPathCodeMI (int &numIndices, const int *&indices, const int *&instanceIndices) |
| Extender API: available to programmers who wish to extend the toolkit | |
| void | traverse (SoNode *node) |
| Does traversal of a graph rooted by a node. | |
| SbBool | hasTerminated () const |
| Returns TRUE if the traversal has reached a termination condition. | |
| const SoPath * | getCurPath () |
| Returns the path accumulated during traversal, i.e., the chain of nodes from the root of the traversed graph to the current node being traversed. | |
| SoState * | getState () const |
| Gets the state from the action. | |
| virtual void | setUpState () |
| Creates state if it is NULL or it is no longer valid because new elements have been enabled since it was created. | |

Abstract base class for picking objects in a scene.
This is an abstract base class for all picking actions. Currently, the only supported subclass is the SoRayPickAction.

static |
Returns the type identifier for this class.
|
virtual |
Returns the type identifier for this specific instance.
Implements SoTypedObject.
Reimplemented in SoRayPickAction.
|
inline |
Returns current viewport region to use for action.

| void SoPickAction::setViewportRegion | ( | const SbViewportRegion & | newRegion | ) |
Sets current viewport region to use for action.
Even though the picking operation may not involve a window per se, some nodes need this information to determine their size and placement.
