/* An explanation of the face data structures. */
ID is the face ID, an integer used internally by the C code to identify
the face,
FONT, FOREGROUND, and BACKGROUND are strings naming the fonts and colors
- to use with the face,
+ to use with the face, FONT may name fontsets,
BACKGROUND-PIXMAP is the name of an x bitmap filename, which we don't
use right now, and
UNDERLINE-P is non-nil if the face should be underlined.
(assq FACE-NAME global-face-data) returns a vector describing the
global parameters for that face.
- Let PARAM-FACE be FRAME->display.x->param_faces[Faref (FACE-VECTOR, 2)].
+ Let PARAM-FACE be FRAME->output_data.w32->param_faces[Faref(FACE-VECTOR,2)].
PARAM_FACE is a struct face whose members are the Xlib analogues of
the parameters in FACE-VECTOR. If an element of FACE-VECTOR is
nil, then the corresponding member of PARAM_FACE is FACE_DEFAULT.
These faces are called "parameter faces", because they're the ones
lisp manipulates to control what gets displayed. Elements 0 and 1
- of FRAME->display.x->param_faces are special - they describe the
+ of FRAME->output_data.w32->param_faces are special - they describe the
default and mode line faces. None of the faces in param_faces have
GC's. (See src/dispextern.h for the definition of struct face.
lisp/faces.el maintains the isomorphism between face_alist and
properties. The resulting faces are called "computed faces"; none
of their members are FACE_DEFAULT; they are completely specified.
They then call intern_compute_face to search
- FRAME->display.x->computed_faces for a matching face, add one if
+ FRAME->output_data.x->computed_faces for a matching face, add one if
none is found, and return the index into
- FRAME->display.x->computed_faces. FRAME's glyph matrices use these
+ FRAME->output_data.x->computed_faces. FRAME's glyph matrices use these
indices to record the faces of the matrix characters, and the X
display hooks consult compute_faces to decide how to display these
characters. Elements 0 and 1 of computed_faces always describe the
This is done from time to time so that we don't hold on to
lots of GCs that are no longer needed.
+ If a computed face has 0 as its font,
