| 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. | |
