annotate lisp/frame.el @ 4546:44129f301385
Make functions in frame.el more general.
(This results in better behaviour on Carbon, notably.)
2008-12-30 Aidan Kehoe <kehoea@parhasard.net>
* frame.el (display-mouse-p):
(display-popup-menus-p):
(display-images-p):
(display-selections-p):
(display-visual-class):
Make all these functions more general, do not hard code device
type symbols where that is inappropriate.

| 1911 ;; If MAJOR-END-P is t, we're looking for a windows that abut the | |
| 1912 ;; end (i.e. right or bottom) of the major axis, instead of the | |
| 1913 ;; start. | |
| 1914 ;; | |
| 1915 ;; If MINOR-END-P is t, then we want to start counting from the | |
| 1916 ;; end of the minor axis instead of the beginning. | |
| 1917 ;; | |
| 1918 ;; Here's the general idea: Imagine we're trying to count the number | |
| 1919 ;; of windows that abut the top; call this function foo(). So, we | |
| 1920 ;; start with the root window. If this is a vertical combination | |
| 1921 ;; window, then foo() applied to the root window is the same as | |
| 1922 ;; foo() applied to the first child. If the root is a horizontal | |
| 1923 ;; combination window, then foo() applied to the root is the | |
| 1924 ;; same as the sum of foo() applied to each of the children. | |
| 1925 ;; Otherwise, the root window is a leaf window, and foo() is 1. | |
| 1926 ;; Now it's clear that, each time foo() encounters a leaf window, | |
| 1927 ;; it's encountering a different window that abuts the top. | |
| 1928 ;; With a little examining, you can see that foo encounters the | |
| 1929 ;; top-abutting windows in order from left to right. We can | |
| 1930 ;; modify foo() to return the nth top-abutting window by simply | |
| 1931 ;; keeping a global variable that is decremented each time | |
| 1932 ;; foo() encounters a leaf window and would return 1. If the | |
| 1933 ;; global counter gets to zero, we've encountered the window | |
| 1934 ;; we were looking for, so we exit right away using a `throw'. | |
| 1935 ;; Otherwise, we make sure that all normal paths return nil. | |
