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

753 important than others. It used to be that size information was
|
|
754 determined at instantiation time and was then fixed forever
|
434
|
755 after. Generally this is not what we want. Users want size to be
|
|
756 "big enough" to accommodate whatever they are trying to show and
|
|
757 this is dependent on text length, lines, font metrics etc. Of
|
|
758 course these attributes can change dynamically and so the size
|
|
759 should changed dynamically also. Only in a few limited cases should
|
|
760 the size be fixed and remain fixed. Of course this actually means
|
|
761 that we don't really want to specifiy the size *at all* for most
|
|
762 widgets - we want it to be discovered dynamically. Thus we can
|
|
763 envisage the following scenarios:
|
|
764
|
|
765 1. A button is sized to accommodate its text, the text changes and the
|
|
766 button should change size also.
|
|
767
|
|
768 2. A button is given an explicit size. Its size should never change.
|
|
769
|
|
770 3. Layout is put inside an area. The size of the area changes, the
|
|
771 layout should change with it.
|
|
772
|
|
773 4. A button grows to accommodate additional text. The whitespace
|
|
774 around it should be modified to cope with the new layout
|
|
775 requirements.
|
|
776
|
|
777 5. A button grows. The area surrounding it should grow also if
|
|
778 possible.
|
|
779
|
|
780 What metrics are important?
|
|
781 1. Actual width and height.
|
|
782
|
|
783 2. Whether the width and height are what the widget actually wants, or
|
|

786 Text glyphs are particularly troublesome since their metrics depend
|
|
787 on the context in which they are being viewed. For instance they
|
|
788 can appear differently depending on the window face, frame face or
|
440
|
789 glyph face. In order to simplify this text glyphs can now only have
|
|
790 a glyph-face or image-instance face. All other glyphs are
|
|
791 essentially fixed in appearance. Perhaps the problem is that text
|
|
792 glyphs are cached on a device basis like most other glyphs. Instead
|
|
793 they should be cached per-window and then the instance would be
|
|
794 fixed and we wouldn't have to mess around with font metrics and the
|
|
795 rest. */
