1081 we would like to address. Some consider some of these more

1082 important than others. It used to be that size information was
|
|
|
1083 determined at instantiation time and was then fixed forever
|
|
434
|
1084 after. Generally this is not what we want. Users want size to be
|
|
|
1085 "big enough" to accommodate whatever they are trying to show and
|
|
|
1086 this is dependent on text length, lines, font metrics etc. Of
|
|
|
1087 course these attributes can change dynamically and so the size
|
|
|
1088 should changed dynamically also. Only in a few limited cases should
|
|
|
1089 the size be fixed and remain fixed. Of course this actually means
|
|
442
|
1090 that we don't really want to specify the size *at all* for most
|
|
434
|
1091 widgets - we want it to be discovered dynamically. Thus we can
|
|
|
1092 envisage the following scenarios:
|
|
442
|
1093
|
|
434
|
1094 1. A button is sized to accommodate its text, the text changes and the
|
|
442
|
1095 button should change size also.
|
|
434
|
1096
|
|
|
1097 2. A button is given an explicit size. Its size should never change.
|
|
|
1098
|
|
|
1099 3. Layout is put inside an area. The size of the area changes, the
|
|
442
|
1100 layout should change with it.
|
|
434
|
1101
|
|
|
1102 4. A button grows to accommodate additional text. The whitespace
|
|
|
1103 around it should be modified to cope with the new layout
|
|
442
|
1104 requirements.
|
|
434
|
1105
|
|
|
1106 5. A button grows. The area surrounding it should grow also if
|
|
442
|
1107 possible.
|
|
434
|
1108
|
|
|
1109 What metrics are important?
|
|
|
1110 1. Actual width and height.
|
|
442
|
1111
|
|
434
|
1112 2. Whether the width and height are what the widget actually wants, or
|
|
442
|
1113 whether it can grow or shrink.
|
|
434
|
1114
|
|
|
1115 Text glyphs are particularly troublesome since their metrics depend
|
|
|
1116 on the context in which they are being viewed. For instance they
|
|
|
1117 can appear differently depending on the window face, frame face or
|
|
440
|
1118 glyph face. In order to simplify this text glyphs can now only have
|
|
|
1119 a glyph-face or image-instance face. All other glyphs are
|
|
|
1120 essentially fixed in appearance. Perhaps the problem is that text
|
|
|
1121 glyphs are cached on a device basis like most other glyphs. Instead
|
|
|
1122 they should be cached per-window and then the instance would be
|
|
|
1123 fixed and we wouldn't have to mess around with font metrics and the
|
|
|
1124 rest. */
