- XXXXmmmmOOOObbbbjjjjeeeeccccttttAAAAttttPPPPooooiiiinnnntttt searches the child list of the specified
- manager _w_i_d_g_e_t and returns the child most closely associated
- with the specified _x,_y coordinate pair.
-
- For the typical Motif manager _w_i_d_g_e_t, XXXXmmmmOOOObbbbjjjjeeeeccccttttAAAAttttPPPPooooiiiinnnnttttuses
- the following rules to determine the returned object:
-
- +o If one child intersects _x,_y, XXXXmmmmOOOObbbbjjjjeeeeccccttttAAAAttttPPPPooooiiiinnnnttttreturns
- the widget ID of that child.
-
- +o If more than one child intersects _x,_y, XXXXmmmmOOOObbbbjjjjeeeeccccttttAAAAttttPPPPooooiiiinnnntttt
- returns the widget ID of the visible child.
-
- +o If no child intersects _x,_y, XXXXmmmmOOOObbbbjjjjeeeeccccttttAAAAttttPPPPooooiiiinnnnttttreturns
- NULL.
-
- The preceding rules are only general. In fact, each manager
- _w_i_d_g_e_t is free to define "most closely associated" as it
- desires. For example, if no child intersects _x,_y, a manager
- might return the child closest to _x,_y.
-
- _w_i_d_g_e_t Specifies a manager widget.
-
- _x Specifies the x-coordinate about which you are
- seeking child information. The x-coordinate must
- be specified in pixels, relative to the left side
- of _m_a_n_a_g_e_r.
-
- _y Specifies the y-coordinate about which you are
- seeking child information. The y-coordinate must
- be specified in pixels, relative to the top side
- of _m_a_n_a_g_e_r.
-
- RRRREEEETTTTUUUURRRRNNNN
- Returns the child of _m_a_n_a_g_e_r most closely associated with
- _x,_y. If none of its children are sufficiently associated
- with _x,_y, returns NULL.
