30 | /* Windows are allocated as if they were vectors, but then the |
31 | Lisp data type is changed to Lisp_Window. They are garbage | |
32 | collected along with the vectors. | |
33 | ||
34 | All windows in use are arranged into a tree, with pointers up and down. | |
35 | ||
36 | Windows that are leaves of the tree are actually displayed | |
37 | and show the contents of buffers. Windows that are not leaves | |
38 | are used for representing the way groups of leaf windows are | |
44fa5b1e | 39 | arranged on the frame. Leaf windows never become non-leaves. |
83b2229f JB |
40 | They are deleted only by calling delete-window on them (but |
41 | this can be done implicitly). Combination windows can be created | |
42 | and deleted at any time. | |
43 | ||
44 | A leaf window has a non-nil buffer field, and also | |
45 | has markers in its start and pointm fields. Non-leaf windows | |
46 | have nil in these fields. | |
47 | ||
48 | Non-leaf windows are either vertical or horizontal combinations. | |
49 | ||
44fa5b1e | 50 | A vertical combination window has children that are arranged on the frame |
83b2229f JB |
51 | one above the next. Its vchild field points to the uppermost child. |
52 | The parent field of each of the children points to the vertical | |
53 | combination window. The next field of each child points to the | |
54 | child below it, or is nil for the lowest child. The prev field | |
55 | of each child points to the child above it, or is nil for the | |
56 | highest child. | |
57 | ||
58 | A horizontal combination window has children that are side by side. | |
59 | Its hchild field points to the leftmost child. In each child | |
60 | the next field points to the child to the right and the prev field | |
61 | points to the child to the left. | |
62 | ||
63 | The children of a vertical combination window may be leaf windows | |
64 | or horizontal combination windows. The children of a horizontal | |
65 | combination window may be leaf windows or vertical combination windows. | |
66 | ||
67 | At the top of the tree are two windows which have nil as parent. | |
68 | The second of these is minibuf_window. The first one manages all | |
44fa5b1e | 69 | the frame area that is not minibuffer, and is called the root window. |
83b2229f JB |
70 | Different windows can be the root at different times; |
71 | initially the root window is a leaf window, but if more windows | |
72 | are created then that leaf window ceases to be root and a newly | |
73 | made combination window becomes root instead. | |
74 | ||
fbfed6f0 JB |
75 | In any case, on screens which have an ordinary window and a |
76 | minibuffer, prev of the minibuf window is the root window and next of | |
77 | the root window is the minibuf window. On minibufferless screens or | |
78 | minibuffer-only screens, the root window and the minibuffer window are | |
27daff1e | 79 | one and the same, so its prev and next members are nil. |
83b2229f | 80 | |
27daff1e | 81 | A dead window has its buffer, hchild, and vchild windows all nil. */ |
