2002-02-06 Havoc Pennington <hp@pobox.com> * src/main.c (main): disable custom log handler and fatal mask for now * src/theme.c (meta_draw_op_list_draw): Add META_DRAW_CLIP * src/main.c: load theme, monitor current theme setting * src/prefs.c: add "current theme" setting * src/stack.c (meta_stack_free): don't try to free last_root_children_stacked if it doesn't exist * src/themewidget.c: pluggable GtkMisc subclass to use for menu icons * src/screen.c (meta_screen_manage_all_windows): fix signed/unsigned warning * src/frames.c: port to theme system (meta_frames_style_set): chain up * theme-format.txt: new file * configure.in: add more compiler warnings * src/theme.c: add various stuff needed to get theme parser working. Remove the "spacer" concept from FrameLayout object. Add draw op that references a draw op list. * configure.in: require GTK 1.3.13 * src/Makefile.am: add theme-parser.[hc], implement loading a theme * src/theme.c: add "draw title" and "draw window icon" operations (meta_draw_op_draw): put object_width/object_height in expression environment before computing x/y. Handle out-of-memory when creating pixbufs. Assorted other cleanups.

Docs on the theme format

|
<!-- define drawing operations to be referenced later;
|

these draw-op lists can also be placed inline.
|
|
|
|
Positions/lengths are given as expressions.
|
|
Operators are: +,-,*,/,%,`max`,`min`
|
|
All operators are infix including `max` and `min`,
|
|
i.e. "2 `max` 5"
|
|
|
|
Some variables are predefined, and constants can also
|
|
be used. Variables are:
|
|
|
|
width - width of target area
|
|
height - height of target area
|
|
object_width - natural width of object being drawn
|
|
object_height - natural height of object being drawn
|
|
left_width - distance from left of frame to client window
|
|
right_width - distance from right of frame to client window
|
|
top_height - distance from top of frame to client window
|
|
bottom_height - distance from bottom of frame to client window
|
|
mini_icon_width - width of mini icon for window
|
|
mini_icon_height - height of mini icon
|
|
icon_width - width of large icon
|
|
icon_height - height of large icon
|
|
title_width - width of title text
|
|
title_height - height of title text
|
|
|
|
All these are always defined, except object_width/object_height
|
|
which only exists for <image> right now.

|
|
For each piece, a draw_ops can be given inline or referenced
|
|
by name. If a piece is omitted, then nothing will be drawn
|
|
for that piece.
|
|
|
|
For each piece, the "width" and "height" variables in
|
|
coordinate expressions refers to the dimensions of the piece,
|
|
the origin is at the top left of the piece.
|
|
|
|
So <rectangle x="0" y="0" width="width-1" height="height-1"/>
|
|
will outline a piece.
