869 we would like to address. Some consider some of these more
|
|
870 important than others. It used to be that size information was
|
|
871 determined at instantiation time and was then fixed forever
|
|
872 after. Generally this is not what we want. Users want size to be
|
|
873 "big enough" to accommodate whatever they are trying to show and
|
|
874 this is dependent on text length, lines, font metrics etc. Of
|
|
875 course these attributes can change dynamically and so the size
|
|
876 should changed dynamically also. Only in a few limited cases should
|
|
877 the size be fixed and remain fixed. Of course this actually means
|
|
878 that we don't really want to specifiy the size *at all* for most
|
|
879 widgets - we want it to be discovered dynamically. Thus we can
|
|
880 envisage the following scenarios:
|
|
881
|
|
882 1. A button is sized to accommodate its text, the text changes and the
|
|
883 button should change size also.
|
|
884
|
|
885 2. A button is given an explicit size. Its size should never change.
|
|
886
|
|
887 3. Layout is put inside an area. The size of the area changes, the
|
|
888 layout should change with it.
|
|
889
|
|
890 4. A button grows to accommodate additional text. The whitespace
|
|
891 around it should be modified to cope with the new layout
|
|
892 requirements.
|
|
893
|
|
894 5. A button grows. The area surrounding it should grow also if
|
|
895 possible.
|
|
896
|
|
897 What metrics are important?
|
|
898 1. Actual width and height.
|
|
899
|
|
900 2. Whether the width and height are what the widget actually wants, or
|
|
901 whether it can grow or shrink.
|
|
902
|
|
903 Text glyphs are particularly troublesome since their metrics depend
|
|
904 on the context in which they are being viewed. For instance they
|
|
905 can appear differently depending on the window face, frame face or
|
|
906 glyph face. In order to simplify this text glyphs can now only have
|
|
907 a glyph-face or image-instance face. All other glyphs are
|
|
908 essentially fixed in appearance. Perhaps the problem is that text
|
|
909 glyphs are cached on a device basis like most other glyphs. Instead
|
|
910 they should be cached per-window and then the instance would be
|
|
911 fixed and we wouldn't have to mess around with font metrics and the
|
|
912 rest. */
