| 1250 we would like to address. Some consider some of these more | |
| 1251 important than others. It used to be that size information was | |
| 1252 determined at instantiation time and was then fixed forever | |
| 434 | 1253 after. Generally this is not what we want. Users want size to be |
| 1254 "big enough" to accommodate whatever they are trying to show and | |
| 1255 this is dependent on text length, lines, font metrics etc. Of | |
| 1256 course these attributes can change dynamically and so the size | |
| 1257 should changed dynamically also. Only in a few limited cases should | |
| 1258 the size be fixed and remain fixed. Of course this actually means | |
| 442 | 1259 that we don't really want to specify the size *at all* for most |
| 434 | 1260 widgets - we want it to be discovered dynamically. Thus we can |
| 1261 envisage the following scenarios: | |
| 442 | 1262 |
| 434 | 1263 1. A button is sized to accommodate its text, the text changes and the |
| 442 | 1264 button should change size also. |
| 434 | 1265 |
| 1266 2. A button is given an explicit size. Its size should never change. | |
| 1267 | |
| 1268 3. Layout is put inside an area. The size of the area changes, the | |
| 442 | 1269 layout should change with it. |
| 434 | 1270 |
| 1271 4. A button grows to accommodate additional text. The whitespace | |
| 1272 around it should be modified to cope with the new layout | |
| 442 | 1273 requirements. |
| 434 | 1274 |
| 1275 5. A button grows. The area surrounding it should grow also if | |
| 442 | 1276 possible. |
| 434 | 1277 |
| 1278 What metrics are important? | |
| 1279 1. Actual width and height. | |
| 442 | 1280 |
| 434 | 1281 2. Whether the width and height are what the widget actually wants, or |
| 442 | 1282 whether it can grow or shrink. |
| 434 | 1283 |
| 1284 Text glyphs are particularly troublesome since their metrics depend | |
| 1285 on the context in which they are being viewed. For instance they | |
| 1286 can appear differently depending on the window face, frame face or | |
| 440 | 1287 glyph face. In order to simplify this text glyphs can now only have |
| 1288 a glyph-face or image-instance face. All other glyphs are | |
| 1289 essentially fixed in appearance. Perhaps the problem is that text | |
| 1290 glyphs are cached on a device basis like most other glyphs. Instead | |
| 1291 they should be cached per-window and then the instance would be | |
| 1292 fixed and we wouldn't have to mess around with font metrics and the | |
| 863 | 1293 rest. |
| 1294 | |
| 1295 Another sizing problem is alignment. We provide layout widgets that | |
| 1296 allow users to stack widgets vertically or horizontally. These | |
| 1297 layouts also allow the widgets to be centered (space evenly | |
| 1298 distributed), left or right justified (fixed spacing widgets | |
| 3094 | 1299 stacked against the left, right, top or bottom edge). Unfortunately |
| 863 | 1300 this doesn't allow widgets in different layouts to be aligned. For |
| 1301 instance how should the search dialog be organized for alignment? | |
| 1302 The obvious choice of two vertical columns does not work since the | |
| 1303 size of individual widgets will affect where they get placed. The | |
| 1304 same is true for several rows of widgets. To solve this problem we | |
| 1305 introduce the notion of `logical_unit_height'. This is a size | |

1306 quantity that is designed to be big enough to accommodate the |
| 863 | 1307 largest `single height unit'. The function |
| 1308 widget_logical_unit_height() determines the value of this in | |
| 1309 pixels. It is dependent on the widget face and some combination of | |
| 1310 spacing and border-width. Thus if users specify left or right | |
| 1311 justification in a vertical layout they get something in logical | |
| 1312 units. To simplify this the functions | |
| 1313 `widget-logical-to-character-height' and | |
| 1314 `widget-logical-to-character-width' allow conversion between | |
| 1315 characters and logical units so that frames can be sized | |
