| 32 /* All windows in use are arranged into a tree, with pointers up and down. | |
| 33 | |
| 34 Windows that are leaves of the tree are actually displayed | |
| 35 and show the contents of buffers. Windows that are not leaves | |
| 36 are used for representing the way groups of leaf windows are | |
| 37 arranged on the frame. Leaf windows never become non-leaves. | |
| 38 They are deleted only by calling delete-window on them (but | |
| 39 this can be done implicitly). Combination windows can be created | |
| 40 and deleted at any time. | |
| 41 | |
| 42 A leaf window has a non-nil buffer field, and also | |
| 43 has markers in its start and pointm fields. Non-leaf windows | |
| 44 have nil in these fields. | |
| 45 | |
| 46 Non-leaf windows are either vertical or horizontal combinations. | |
| 47 | |
| 48 A vertical combination window has children that are arranged on the frame | |
| 49 one above the next. Its vchild field points to the uppermost child. | |
| 50 The parent field of each of the children points to the vertical | |
| 51 combination window. The next field of each child points to the | |
| 52 child below it, or is nil for the lowest child. The prev field | |
| 53 of each child points to the child above it, or is nil for the | |
| 54 highest child. | |
| 55 | |
| 56 A horizontal combination window has children that are side by side. | |
| 57 Its hchild field points to the leftmost child. In each child | |
| 58 the next field points to the child to the right and the prev field | |
| 59 points to the child to the left. | |
| 60 | |
| 61 The children of a vertical combination window may be leaf windows | |
| 62 or horizontal combination windows. The children of a horizontal | |
| 63 combination window may be leaf windows or vertical combination windows. | |
| 64 | |
| 65 At the top of the tree are two windows which have nil as parent. | |
| 66 The second of these is minibuf_window. The first one manages all | |
| 67 the frame area that is not minibuffer, and is called the root window. | |
| 68 Different windows can be the root at different times; | |
| 69 initially the root window is a leaf window, but if more windows | |
| 70 are created then that leaf window ceases to be root and a newly | |
| 71 made combination window becomes root instead. | |
| 72 | |
| 73 In any case, on screens which have an ordinary window and a | |
| 74 minibuffer, prev of the minibuf window is the root window and next of | |
| 75 the root window is the minibuf window. On minibufferless screens or | |
| 76 minibuffer-only screens, the root window and the minibuffer window are | |
| 77 one and the same, so its prev and next members are nil. | |
| 78 | |
| 79 A dead window has the `dead' flag set on it. Note that unlike other | |
| 80 dead objects, dead windows can be made live again through restoring a | |
| 81 window configuration. This means that the values in a dead window | |
| 82 need to be preserved, except for those that are reconstructed by from | |
| 83 the window configuration. */ | |
