* redisplay.c (pixel_to_glyph_translation):
* toolbar.c (update_frame_toolbars_geometry):
* window.c (Fwindow_pixel_edges):
Get rid of some redundant macros. Consistently use the
FRAME_TOP_*_START, FRAME_RIGHT_*_END, etc. format. Rename
FRAME_*_BORDER_* to FRAME_*_INTERNAL_BORDER_*. Comment out
FRAME_BOTTOM_* for gutters and the paned area due to the
uncertainty over where the paned area actually begins. (Eventually
we should probably move the gutters outside the minibuffer so that
the paned area is contiguous.) Use FRAME_PANED_* more often in the
code to make things clearer.
Update the diagram to show that the bottom gutter is inside the
minibuffer (!) and that there are "junk boxes" when you have left
and/or right gutters (dead boxes that are mistakenly left uncleared,
unlike the corresponding scrollbar dead boxes). Update the text
appropriately to cover the bottom gutter position, etc.
Rewrite gutter-geometry code to use the FRAME_*_GUTTER_* in place of
equivalent expressions referencing other frame elements, to make the
code more portable in case we move around the gutter location.
Cleanup FRAME_*_GUTTER_BOUNDS() in gutter.h.
Add some #### GEOM! comments where I think code is incorrect --
typically, it wasn't fixed up properly when the gutter was added.
Some cosmetic changes.

| 84 Note in particular what happens at the corners, where a "corner box" | |
| 85 occurs. Top and bottom toolbars take precedence over left and right | |
| 86 toolbars, extending out horizontally into the corner boxes. Gutters | |
| 87 work the same way. The corner box where the scrollbars meet, however, | |
| 88 is assigned to neither scrollbar, and is known as the "dead box"; it is | |
| 5090 | 89 an area that must be cleared specially. There are similar dead boxes at |
| 90 the bottom-right and bottom-left corners where the minibuffer and | |
| 91 left/right gutters meet, but there is currently a bug in that these dead | |
| 92 boxes are not explicitly cleared and may contain junk. | |
| 5043 | 93 |
| 94 THE FRAME | |
| 95 --------- | |
| 96 | |
| 97 The "top-level window area" is the entire area of a top-level window (or | |
| 98 "frame"). The "client area" (a term from MS Windows) is the area of a | |
| 99 top-level window that XEmacs draws into and manages with redisplay. | |
| 100 This includes the toolbar, scrollbars, gutters, dividers, text area, | |
| 101 modeline and minibuffer. It does not include the menubar, title or | |
| 102 outer borders. The "non-client area" is the area of a top-level window | |
| 103 outside of the client area and includes the menubar, title and outer | |
| 104 borders. Internally, all frame coordinates are relative to the client | |
| 105 area. | |
| 106 | |
| 107 | |
| 108 THE NON-CLIENT AREA | |
| 109 ------------------- | |
| 110 | |
| 111 Under X, the non-client area is split into two parts: | |
| 112 | |
| 113 (1) The outer layer is the window-manager decorations: The title and | |
| 114 borders. These are controlled by the window manager, a separate process | |
| 115 that controls the desktop, the location of icons, etc. When a process | |
| 116 tries to create a window, the window manager intercepts this action and | |
| 117 "reparents" the window, placing another window around it which contains | |
| 118 the window decorations, including the title bar, outer borders used for | |
| 119 resizing, etc. The window manager also implements any actions involving | |
| 120 the decorations, such as the ability to resize a window by dragging its | |
| 121 borders, move a window by dragging its title bar, etc. If there is no | |
| 122 window manager or you kill it, windows will have no decorations (and | |
| 123 will lose them if they previously had any) and you will not be able to | |
| 124 move or resize them. | |
| 125 | |
| 126 (2) Inside of the window-manager decorations is the "shell", which is | |
| 127 managed by the toolkit and widget libraries your program is linked with. | |
| 128 The code in *-x.c uses the Xt toolkit and various possible widget | |
| 129 libraries built on top of Xt, such as Motif, Athena, the "Lucid" | |
| 130 widgets, etc. Another possibility is GTK (*-gtk.c), which implements | |
| 131 both the toolkit and widgets. Under Xt, the "shell" window is an | |
| 132 EmacsShell widget, containing an EmacsManager widget of the same size, | |
| 133 which in turn contains a menubar widget and an EmacsFrame widget, inside | |
| 134 of which is the client area. (The division into EmacsShell and | |
| 135 EmacsManager is due to the complex and screwy geometry-management system | |
| 136 in Xt [and X more generally]. The EmacsShell handles negotation with | |
| 137 the window manager; the place of the EmacsManager widget is normally | |
| 138 assumed by a widget that manages the geometry of its child widgets, but | |
| 139 the EmacsManager widget just lets the XEmacs redisplay mechanism do the | |
| 140 positioning.) | |
| 141 | |
| 142 Under Windows, the non-client area is managed by the window system. | |
| 143 There is no division such as under X. Part of the window-system API | |
| 144 (USER.DLL) of Win32 includes functions to control the menubars, title, | |
| 145 etc. and implements the move and resize behavior. There *is* an | |
| 146 equivalent of the window manager, called the "shell", but it manages | |
| 147 only the desktop, not the windows themselves. The normal shell under | |
| 148 Windows is EXPLORER.EXE; if you kill this, you will lose the bar | |
| 149 containing the "Start" menu and tray and such, but the windows | |
| 150 themselves will not be affected or lose their decorations. | |
| 151 | |
| 152 | |
| 153 THE CLIENT AREA | |
| 154 --------------- | |
| 155 | |
| 156 Inside of the client area is the toolbars, the gutters (where the buffer | |
| 157 tabs are displayed), the minibuffer, the internal border width, and one | |
| 158 or more non-overlapping "windows" (this is old Emacs terminology, from | |
| 159 before the time when frames existed at all; the standard terminology for | |
| 160 this would be "pane"). Each window can contain a modeline, horizontal | |
| 161 and/or vertical scrollbars, and (for non-rightmost windows) a vertical | |
| 162 divider, surrounding a text area. | |
| 163 | |
| 164 The dimensions of the toolbars and gutters are determined by the formula | |
| 165 (THICKNESS + 2 * BORDER-THICKNESS), where "thickness" is a cover term | |
| 166 for height or width, as appropriate. The height and width come from | |
| 167 `default-toolbar-height' and `default-toolbar-width' and the specific | |
| 168 versions of these (`top-toolbar-height', `left-toolbar-width', etc.). | |
| 169 The border thickness comes from `default-toolbar-border-height' and | |
| 170 `default-toolbar-border-width', and the specific versions of these. The | |
| 171 gutter works exactly equivalently. | |
| 172 | |
| 173 Note that for any particular toolbar or gutter, it will only be | |
| 174 displayed if [a] its visibility specifier (`default-toolbar-visible-p' | |
| 175 etc.) is non-nil; [b] its thickness (`default-toolbar-height' etc.) is | |
| 176 greater than 0; [c] its contents (`default-toolbar' etc.) are non-nil. | |
| 177 | |
| 178 The position-specific toolbars interact with the default specifications | |
| 179 as follows: If the value for a position-specific specifier is not | |
| 180 defined in a particular domain (usually a window), and the position of | |
| 181 that specifier is set as the default position (using | |
| 182 `default-toolbar-position'), then the value from the corresponding | |
| 183 default specifier in that domain will be used. The gutters work the | |
| 184 same. | |
| 185 | |
| 186 | |
| 187 THE PANED AREA | |
| 188 -------------- | |
| 189 | |
| 5090 | 190 The area occupied by the "windows" is called the paned area. Unfortunately, |
| 191 because of the presence of the gutter *between* the minibuffer and other | |
| 192 windows, the bottom of the paned area is not well-defined -- does it | |
| 193 include the minibuffer (in which case it also includes the bottom gutter, | |
| 194 but none others) or does it not include the minibuffer? (In which case | |
| 195 not all windows are included.) #### GEOM! It would be cleaner to put the | |
| 196 bottom gutter *below* the minibuffer instead of above it. | |
| 197 | |
| 198 Each window can include a horizontal and/or vertical scrollbar, a | |
| 199 modeline and a vertical divider to its right, as well as the text area. | |
| 200 Only non-rightmost windows can include a vertical divider. (The | |
| 201 minibuffer normally does not include either modeline or scrollbars.) | |
| 5043 | 202 |
| 203 Note that, because the toolbars and gutters are controlled by | |
| 204 specifiers, and specifiers can have window-specific and buffer-specific | |
| 205 values, the size of the paned area can change depending on which window | |
| 206 is selected: In other words, if the selected window or buffer changes, | |
| 207 the entire paned area for the frame may change. | |
| 208 | |
| 209 | |
| 210 TEXT AREAS, FRINGES, MARGINS | |
| 211 ---------------------------- | |
| 212 | |
| 213 The space occupied by a window can be divided into the text area and the | |
| 214 fringes. The fringes include the modeline, scrollbars and vertical | |
| 215 divider on the right side (if any); inside of this is the text area, | |
| 216 where the text actually occurs. Note that a window may or may not | |
| 217 contain any of the elements that are part of the fringe -- this is | |
| 218 controlled by specifiers, e.g. `has-modeline-p', | |
| 219 `horizontal-scrollbar-visible-p', `vertical-scrollbar-visible-p', | |
| 220 `vertical-divider-always-visible-p', etc. | |
| 221 | |
| 222 In addition, it is possible to set margins in the text area using the | |
| 223 specifiers `left-margin-width' and `right-margin-width'. When this is | |
| 224 done, only the "inner text area" (the area inside of the margins) will | |
| 225 be used for normal display of text; the margins will be used for glyphs | |
| 226 with a layout policy of `outside-margin' (as set on an extent containing | |
| 227 the glyph by `set-extent-begin-glyph-layout' or | |
| 228 `set-extent-end-glyph-layout'). However, the calculation of the text | |
| 229 area size (e.g. in the function `window-text-area-width') includes the | |
| 230 margins. Which margin is used depends on whether a glyph has been set | |
| 231 as the begin-glyph or end-glyph of an extent (`set-extent-begin-glyph' | |
| 232 etc.), using the left and right margins, respectively. | |
| 233 | |
| 234 Technically, the margins outside of the inner text area are known as the | |
| 235 "outside margins". The "inside margins" are in the inner text area and | |
| 236 constitute the whitespace between the outside margins and the first or | |
| 237 last non-whitespace character in a line; their width can vary from line | |
| 238 to line. Glyphs will be placed in the inside margin if their layout | |
| 239 policy is `inside-margin' or `whitespace', with `whitespace' glyphs on | |
| 240 the inside and `inside-margin' glyphs on the outside. Inside-margin | |
| 241 glyphs can spill over into the outside margin if `use-left-overflow' or | |
| 242 `use-right-overflow', respectively, is non-nil. | |
| 243 | |
| 244 See the Lisp Reference manual, under Annotations, for more details. | |
| 245 | |
| 246 | |
| 247 THE DISPLAYABLE AREA | |
| 248 -------------------- | |
| 249 | |
| 250 The "displayable area" is not so much an actual area as a convenient | |
| 251 fiction. It is the area used to convert between pixel and character | |
| 252 dimensions for frames. The character dimensions for a frame (e.g. as | |
| 253 returned by `frame-width' and `frame-height' and set by | |
| 254 `set-frame-width' and `set-frame-height') are determined from the | |
| 255 displayable area by dividing by the pixel size of the default font as | |
| 256 instantiated in the frame. (For proportional fonts, the "average" width | |
| 257 is used. Under Windows, this is a built-in property of the fonts. | |
| 258 Under X, this is based on the width of the lowercase 'n', or if this is | |
| 259 zero then the width of the default character. [We prefer 'n' to the | |
| 260 specified default character because many X fonts have a default | |
| 261 character with a zero or otherwise non-representative width.]) | |
| 262 | |
| 5090 | 263 The displayable area is essentially the "theoretical" gutter area of the |
| 264 frame, excluding the rightmost and bottom-most scrollbars. That is, it | |
| 265 starts from the client (or "total") area and then excludes the | |
| 266 "theoretical" toolbars and bottom-most/rightmost scrollbars, and the | |
| 267 internal border width. In this context, "theoretical" means that all | |
| 268 calculations on based on frame-level values for toolbar and scrollbar | |
| 269 thicknesses. Because these thicknesses are controlled by specifiers, | |
| 270 and specifiers can have window-specific and buffer-specific values, | |
| 271 these calculations may or may not reflect the actual size of the paned | |
| 272 area or of the scrollbars when any particular window is selected. Note | |
| 273 also that the "displayable area" may not even be contiguous! In | |
| 274 particular, the gutters are included, but the bottom-most and rightmost | |
| 275 scrollbars are excluded even though they are inside of the gutters. | |
| 276 Furthermore, if the frame-level value of the horizontal scrollbar height | |
| 277 is non-zero, then the displayable area includes the paned area above and | |
| 278 below the bottom horizontal scrollbar (i.e. the modeline and minibuffer) | |
| 279 but not the scrollbar itself. | |
| 5043 | 280 |
| 281 As a further twist, the character-dimension calculations are adjusted so | |
| 282 that the truncation and continuation glyphs (see `truncation-glyph' and | |
| 283 `continuation-glyph') count as a single character even if they are wider | |
| 284 than the default font width. (Technically, the character width is | |
| 285 computed from the displayable-area width by subtracting the maximum of | |
| 286 the truncation-glyph width, continuation-glyph width and default-font | |
| 287 width before dividing by the default-font width, and then adding 1 to | |
| 288 the result.) (The ultimate motivation for this kludge as well as the | |
| 289 subtraction of the scrollbars, but not the minibuffer or bottom-most | |
| 290 modeline, is to maintain compatibility with TTY's.) | |
| 291 | |
| 292 Despite all these concerns and kludges, however, the "displayable area" | |
| 293 concept works well in practice and mostly ensures that by default the | |
| 294 frame will actually fit 79 characters + continuation/truncation glyph. | |

| 428 | 1655 |
| 3025 | 1656 `visible' Consider only frames that are visible. |
| 1657 `iconic' Consider only frames that are iconic. | |
| 1658 `invisible' Consider only frames that are invisible | |
| 4207 | 1659 (this is different from iconic). |
| 3025 | 1660 `visible-iconic' Consider frames that are visible or iconic. |
| 1661 `invisible-iconic' Consider frames that are invisible or iconic. | |
| 1662 `nomini' Consider all frames except minibuffer-only ones. | |
| 1663 `visible-nomini' Like `visible' but omits minibuffer-only frames. | |
| 1664 `iconic-nomini' Like `iconic' but omits minibuffer-only frames. | |
| 1665 `invisible-nomini' Like `invisible' but omits minibuffer-only frames. | |
| 1666 `visible-iconic-nomini' Like `visible-iconic' but omits minibuffer-only | |
| 4207 | 1667 frames. |
| 3025 | 1668 `invisible-iconic-nomini' Like `invisible-iconic' but omits minibuffer-only |
| 4207 | 1669 frames. |
| 3025 | 1670 any other value Consider all frames. |
| 1671 | |
| 1672 If WHICH-FRAMES is omitted, `nomini' is used. A value for WHICH-FRAMES | |
| 1673 of 0 (a number) is treated like `iconic', for backwards compatibility. | |
| 444 | 1674 |
| 1675 If WHICH-FRAMES is a window, include only its own frame and any frame | |
| 1676 now using that window as the minibuffer. | |
| 1677 | |
| 1678 The optional third argument WHICH-DEVICES further clarifies on which | |
| 1679 devices to search for frames as specified by WHICH-FRAMES. | |
| 1680 If nil or omitted, search all devices on FRAME's console. | |
| 1681 If a device, only search that device. | |
| 1682 If a console, search all devices on that console. | |
| 1683 If a device type, search all devices of that type. | |
| 1684 If `window-system', search all window-system devices. | |
| 1685 Any other non-nil value means search all devices. | |
