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.
