|
|
|
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 accomodate the
|
|
|
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
|
|
|
1316 appropriately. */
