Methods from class SoPickAction:

void setViewportRegion(const SbViewportRegion &newRegion)

const SbViewportRegion & getViewportRegion() const

Methods from class SoAction:

virtual void apply(SoNode *node)

virtual void apply(SoPath *path)

virtual void apply(const SoPathList &pathList, SbBool obeysRules = FALSE)

static SoType getClassTypeId()

virtual SoType getTypeId()

virtual SbBool isOfType(SoType type)

virtual void invalidateState()

DESCRIPTION¶

This is an abstract base class for all picking actions. Currently, the only supported subclass is the SoRayPickAction.

METHODS¶

void setViewportRegion(const SbViewportRegion &newRegion)

const SbViewportRegion & getViewportRegion() const

Sets/returns 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.
