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