|

830 we would like to address. Some consider some of these more
|
|
|
831 important than others. It used to be that size information was
|
|
|
832 determined at instantiation time and was then fixed forever
|
|
|
833 after. Generally this is not what we want. Users want size to be
|
|
|
834 "big enough" to accommodate whatever they are trying to show and
|
|
|
835 this is dependent on text length, lines, font metrics etc. Of
|
|
|
836 course these attributes can change dynamically and so the size
|
|
|
837 should changed dynamically also. Only in a few limited cases should
|
|
|
838 the size be fixed and remain fixed. Of course this actually means
|
|
|
839 that we don't really want to specifiy the size *at all* for most
|
|
|
840 widgets - we want it to be discovered dynamically. Thus we can
|
|
|
841 envisage the following scenarios:
|
|
|
842
|
|
|
843 1. A button is sized to accommodate its text, the text changes and the
|
|
|
844 button should change size also.
|
|
|
845
|
|
|
846 2. A button is given an explicit size. Its size should never change.
|
|
|
847
|
|
|
848 3. Layout is put inside an area. The size of the area changes, the
|
|
|
849 layout should change with it.
|
|
|
850
|
|
|
851 4. A button grows to accommodate additional text. The whitespace
|
|
|
852 around it should be modified to cope with the new layout
|
|
|
853 requirements.
|
|
|
854
|
|
|
855 5. A button grows. The area surrounding it should grow also if
|
|
|
856 possible.
|
|
|
857
|
|
|
858 What metrics are important?
|
|
|
859 1. Actual width and height.
|
|
|
860
|
|
|
861 2. Whether the width and height are what the widget actually wants, or
|
|
|
862 whether it can grow or shrink.
|
|
|
863
|
|
|
864 Text glyphs are particularly troublesome since their metrics depend
|
|
|
865 on the context in which they are being viewed. For instance they
|
|
|
866 can appear differently depending on the window face, frame face or
|
|
|
867 glyph face. In order to simplify this text glyphs can now only have
|
|
|
868 a glyph-face or image-instance face. All other glyphs are
|
|
|
869 essentially fixed in appearance. Perhaps the problem is that text
|
|
|
870 glyphs are cached on a device basis like most other glyphs. Instead
|
|
|
871 they should be cached per-window and then the instance would be
|
|
|
872 fixed and we wouldn't have to mess around with font metrics and the
|
|
|
873 rest. */
