public class focus_sem_draw_context

extends bounds_sem_draw_context

This class provides a traversal "parameters" object that encapsulates the context of a draw done from inside a semantic lens. In particular, this class tracks current and target depths, useful for determining lens behavior based on an interactor's depth or child number in the interactor tree. It also maintains a 'focus' Vector and displays information only for elements in this focus.

Construct from another object.

focus_sem_draw_context(int drw_knd, drawable surf)
Constructor.

focus_sem_draw_context(int drw_knd, drawable surf, semantic_lens lens, int current_depth, int target_depth_start, int target_depth_end, int current_child, int target_child_start, int target_child_end, java.util.Vector targets)
Full constructor.

focus_sem_draw_context(int drw_knd, drawable surf, semantic_lens lens, int target_depth_start, int target_depth_end, int target_child_start, int target_child_end, java.util.Vector targets)
Constructor, initializes the current depth and child number to zero.

Method Summary

void	set_targets(java.util.Vector targets) Sets the interactors we are focussed on- not sure what the application for this is, yet, but there may be something interesting, such as an agent that sets the targets to every instance of some class
java.util.Vector	targets() Returns the interactors we are focussed on
