434

+ − 1073 course these attributes can change dynamically and so the size

442

434

442
+ − 1079
434
+ − 1080 1. A button is sized to accommodate its text, the text changes and the
442
+ − 1081 button should change size also.
434
+ − 1082
+ − 1083 2. A button is given an explicit size. Its size should never change.
+ − 1084
+ − 1085 3. Layout is put inside an area. The size of the area changes, the
442
+ − 1086 layout should change with it.
434
+ − 1087
+ − 1088 4. A button grows to accommodate additional text. The whitespace
+ − 1089 around it should be modified to cope with the new layout
442
+ − 1090 requirements.
434
+ − 1091
+ − 1092 5. A button grows. The area surrounding it should grow also if

+ − 1095 What metrics are important?
+ − 1096 1. Actual width and height.
442
+ − 1097
434
+ − 1098 2. Whether the width and height are what the widget actually wants, or
442
+ − 1099 whether it can grow or shrink.
434
+ − 1100
+ − 1101 Text glyphs are particularly troublesome since their metrics depend
+ − 1102 on the context in which they are being viewed. For instance they
+ − 1103 can appear differently depending on the window face, frame face or
440
+ − 1104 glyph face. In order to simplify this text glyphs can now only have
+ − 1105 a glyph-face or image-instance face. All other glyphs are
+ − 1106 essentially fixed in appearance. Perhaps the problem is that text
+ − 1107 glyphs are cached on a device basis like most other glyphs. Instead
