- TTTTkkkk____CCCCoooooooorrrrddddssssTTTTooooWWWWiiiinnnnddddoooowwww locates the window that contains a given
- point. The point is specified in root coordinates with
- _r_o_o_t_X and _r_o_o_t_Y (if a virtual-root window manager is in use |
- then _r_o_o_t_X and _r_o_o_t_Y are in the coordinate system of the |
- virtual root window). The return value from the procedure
- is a token for the window that contains the given point. If
- the point is not in any window, or if the containing window
- is not in the same application as _t_k_w_i_n, then NULL is
- returned.
-
- The containing window is decided using the same rules that
- determine which window contains the mouse cursor: if a
- parent and a child both contain the point then the child
- gets preference, and if two siblings both contain the point
- then the highest one in the stacking order (i.e. the one
- that's visible on the screen) gets preference.
