915 we would like to address. Some consider some of these more
|
|
916 important than others. It used to be that size information was
|
|
917 determined at instantiation time and was then fixed forever
|
|
918 after. Generally this is not what we want. Users want size to be
|
|
919 "big enough" to accommodate whatever they are trying to show and
|
|
920 this is dependent on text length, lines, font metrics etc. Of
|
|
921 course these attributes can change dynamically and so the size
|
|
922 should changed dynamically also. Only in a few limited cases should
|
|
923 the size be fixed and remain fixed. Of course this actually means
|
|
924 that we don't really want to specifiy the size *at all* for most
|
|
925 widgets - we want it to be discovered dynamically. Thus we can
|
|
926 envisage the following scenarios:
|
|
927
|
|
928 1. A button is sized to accommodate its text, the text changes and the
|
|
929 button should change size also.
|
|
930
|
|
931 2. A button is given an explicit size. Its size should never change.
|
|
932
|
|
933 3. Layout is put inside an area. The size of the area changes, the
|
|
934 layout should change with it.
|
|
935
|
|
936 4. A button grows to accommodate additional text. The whitespace
|
|
937 around it should be modified to cope with the new layout
|
|
938 requirements.
|
|
939
|
|
940 5. A button grows. The area surrounding it should grow also if
|
|
941 possible.
|
|
942
|
|
943 What metrics are important?
|
|
944 1. Actual width and height.
|
|
945
|
|
946 2. Whether the width and height are what the widget actually wants, or
|
|
947 whether it can grow or shrink.
|
|
948
|
|
949 Text glyphs are particularly troublesome since their metrics depend
|
|
950 on the context in which they are being viewed. For instance they
|
|
951 can appear differently depending on the window face, frame face or
|
|
952 glyph face. In order to simplify this text glyphs can now only have
|
|
953 a glyph-face or image-instance face. All other glyphs are
|
|
954 essentially fixed in appearance. Perhaps the problem is that text
|
|
955 glyphs are cached on a device basis like most other glyphs. Instead
|
|
956 they should be cached per-window and then the instance would be
|
|
957 fixed and we wouldn't have to mess around with font metrics and the
|
|
958 rest. */
