| 1942 | 43 ;; XEmacs change: Emacs no longer specifies the minibuffer property here. |
| 428 | 44 ;;; The initial value given here for this must ask for a minibuffer. |

| 52 The format of this can also be an alist for backward compatibility. | |

| 54 If the value calls for a frame without a minibuffer, and you have not created | |

| 56 `minibuffer-frame-plist'. | |

| 58 You can specify geometry-related options for just the initial frame | |
| 59 by setting this variable in your `.emacs' file; however, they won't | |
| 60 take effect until Emacs reads `.emacs', which happens after first creating | |
| 61 the frame. If you want the frame to have the proper geometry as soon | |
| 62 as it appears, you need to use this three-step process: | |
| 63 * Specify X resources to give the geometry you want. | |
| 64 * Set `default-frame-plist' to override these options so that they | |
| 65 don't affect subsequent frames. | |

| 1927 ;; bottom. The "minor axis" always goes perpendicularly. | |
| 1928 ;; | |

| 1932 ;; | |
| 1933 ;; If MINOR-END-P is t, then we want to start counting from the | |
| 1934 ;; end of the minor axis instead of the beginning. | |
| 1935 ;; | |
| 1936 ;; Here's the general idea: Imagine we're trying to count the number | |
| 1937 ;; of windows that abut the top; call this function foo(). So, we | |
| 1938 ;; start with the root window. If this is a vertical combination | |
| 1939 ;; window, then foo() applied to the root window is the same as | |
| 1940 ;; foo() applied to the first child. If the root is a horizontal | |
| 1941 ;; combination window, then foo() applied to the root is the | |
| 1942 ;; same as the sum of foo() applied to each of the children. | |
| 1943 ;; Otherwise, the root window is a leaf window, and foo() is 1. | |
| 1944 ;; Now it's clear that, each time foo() encounters a leaf window, | |
| 1945 ;; it's encountering a different window that abuts the top. | |
| 1946 ;; With a little examining, you can see that foo encounters the | |
| 1947 ;; top-abutting windows in order from left to right. We can | |
| 1948 ;; modify foo() to return the nth top-abutting window by simply | |
| 1949 ;; keeping a global variable that is decremented each time | |
| 1950 ;; foo() encounters a leaf window and would return 1. If the | |
| 1951 ;; global counter gets to zero, we've encountered the window | |
| 1952 ;; we were looking for, so we exit right away using a `throw'. | |
