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