2 * Unified font management for GTK.
4 * PuTTY is willing to use both old-style X server-side bitmap
5 * fonts _and_ GTK2/Pango client-side fonts. This requires us to
6 * do a bit of work to wrap the two wildly different APIs into
7 * forms the rest of the code can switch between seamlessly, and
8 * also requires a custom font selector capable of handling both
16 #include <gdk/gdkkeysyms.h>
19 #include <X11/Xutil.h>
20 #include <X11/Xatom.h>
30 * - implement the preview pane
32 * - extend the font style language for X11 fonts so that we
33 * never get unexplained double size elements? Or, at least, so
34 * that _my_ font collection never produces them; that'd be a
37 * - decide what _should_ happen about font aliases. Should we
38 * resolve them as soon as they're clicked? Or be able to
39 * resolve them on demand, er, somehow? Or resolve them on exit
40 * from the function? Or what? If we resolve on demand, should
41 * we stop canonifying them on input, on the basis that we'd
42 * prefer to let the user _tell_ us when to canonify them?
44 * - think about points versus pixels, harder than I already have
46 * - work out why the list boxes don't go all the way to the RHS
49 * - big testing and shakedown!
55 * - all the GDK font functions used in the x11font subclass are
56 * deprecated, so one day they may go away. When this happens -
57 * or before, if I'm feeling proactive - it oughtn't to be too
58 * difficult in principle to convert the whole thing to use
59 * actual Xlib font calls.
61 * - it would be nice if we could move the processing of
62 * underline and VT100 double width into this module, so that
63 * instead of using the ghastly pixmap-stretching technique
64 * everywhere we could tell the Pango backend to scale its
65 * fonts to double size properly and at full resolution.
66 * However, this requires me to learn how to make Pango stretch
67 * text to an arbitrary aspect ratio (for double-width only
68 * text, which perversely is harder than DW+DH), and right now
69 * I haven't the energy.
73 * Ad-hoc vtable mechanism to allow font structures to be
76 * Any instance of `unifont' used in the vtable functions will
77 * actually be the first element of a larger structure containing
78 * data specific to the subtype. This is permitted by the ISO C
79 * provision that one may safely cast between a pointer to a
80 * structure and a pointer to its first element.
