remove duplicative code in change_frame_size()
-------------------- ChangeLog entries follow: --------------------
src/ChangeLog addition:
2010-02-15 Ben Wing <ben@xemacs.org>
* frame.c (change_frame_size_1):
Simplify the logic in this function.
(1) Don't allow 0 as the value of height or width. The old code
that tried to allow this was totally broken, anyway, so obviously
this never happens any more.
(2) Don't duplicate the code in frame_conversion_internal() that
converts displayable pixel size to total pixel size -- just call
that function.

| 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. | |
