| 61 as it appears, you need to use this three-step process: | |

| 1893 ;; By adding primitives to directly access the window hierarchy, | |
| 1894 ;; we can move many functions into Lisp. We do it this way | |
| 1895 ;; because the implementations are simpler in Lisp, and because | |
| 1896 ;; new functions like this can be added without requiring C | |
| 1897 ;; additions. | |

| 1901 ;; LEFT-RIGHT-P means we're looking for the leftmost or rightmost | |
| 1902 ;; window, instead of the highest or lowest. In this case, we | |
| 1903 ;; say that the "major axis" goes left-to-right instead of top-to- | |
| 1904 ;; bottom. The "minor axis" always goes perpendicularly. | |
| 1905 ;; | |
| 1906 ;; If MAJOR-END-P is t, we're looking for a windows that abut the | |
| 1907 ;; end (i.e. right or bottom) of the major axis, instead of the | |
| 1908 ;; start. | |
| 1909 ;; | |
| 1910 ;; If MINOR-END-P is t, then we want to start counting from the | |
| 1911 ;; end of the minor axis instead of the beginning. | |
| 1912 ;; | |
| 1913 ;; Here's the general idea: Imagine we're trying to count the number | |
| 1914 ;; of windows that abut the top; call this function foo(). So, we | |
| 1915 ;; start with the root window. If this is a vertical combination | |
| 1916 ;; window, then foo() applied to the root window is the same as | |
| 1917 ;; foo() applied to the first child. If the root is a horizontal | |
| 1918 ;; combination window, then foo() applied to the root is the | |
| 1919 ;; same as the sum of foo() applied to each of the children. | |
| 1920 ;; Otherwise, the root window is a leaf window, and foo() is 1. | |
| 1921 ;; Now it's clear that, each time foo() encounters a leaf window, | |
| 1922 ;; it's encountering a different window that abuts the top. | |
| 1923 ;; With a little examining, you can see that foo encounters the | |
| 1924 ;; top-abutting windows in order from left to right. We can | |
| 1925 ;; modify foo() to return the nth top-abutting window by simply | |
| 1926 ;; keeping a global variable that is decremented each time | |
| 1927 ;; foo() encounters a leaf window and would return 1. If the | |
| 1928 ;; global counter gets to zero, we've encountered the window | |
| 1929 ;; we were looking for, so we exit right away using a `throw'. | |
| 1930 ;; Otherwise, we make sure that all normal paths return nil. | |
