Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning)
2001-07-24 Michael Natterer <mitch@gimp.org>
Port to glib/gtk+ 2.0 episode I (every segfault has it's beginning)
* configure.in: require glib/gtk+ >= 1.3.7, commented out the
gtkxmhtml stuff.
From now on, you will need glib, pango, atk and gtk+ HEAD from CVS
to hack or use GIMP HEAD.
Beware, it crashes randomly :)
* app/core/Makefile.am
* app/core/gimpmarshal.list: new file plus rules to generate
gimpmarshal.[ch] from it.
* app/core/*
* app/tools/*
* app/widgets/*
* libgimpwidgets/*: started to use the glib object system. All
core/ objects are still gtk objects however. All signals are
created using g_signal_new(). There are many gtk+ artefacts left.
Finally, we will _not_ use the gtk_signal_foo() wrappers and
friends any more.

gchar*", switch from GdkDeviceInfo to GdkDevice (very incomplete
and currently disables), lots of s/gtk_signal/g_signal/,
removal/replacement of deprecated stuff,
s/GtkSignalFunc/GCallback/ and lots of small changes and fixes
while I was on it, zillions of warnings left...
* modules/Makefile.am: disabled the water color selector
temporarily (XInput issues).
* plug-ins/Makefile.am
* plug-ins/common/.cvsignore
* plug-ins/common/Makefile.am
* plug-ins/common/plugin-defs.pl: simply excluded all plug-ins
which did not build (including Script-Fu). They are trivial to
fix.

/* Special undo types */
|
Honest, guv, it's not a feature - it's a tightly integrated package of
Mon Sep 20 12:51:30 EDT 1999 Austin Donnelly <austin@gimp.org>
Honest, guv, it's not a feature - it's a tightly integrated
package of undo system cleanups and fixes.
NEW FILES:
* app/undo_history.c: window showing recent undo (and redo) steps
available.
* app/undo_types.h: broken out of undo.h to fix circular includes.
MODIFIED FILES:
* app/Makefile.am: compile undo_history.c
* app/channel.h: use enum for channel undo type, not just magic
numbers.
* app/layer.h: same for layer undos.
* app/commands.c: edit_show_undo_history_cmd_callback() function to
pull up undo history window.
* app/commands.h: prototype for above.
* app/gdisplay.c: make undo / redo menu items sensitive according
to whether they would do anything. Would be easy to change
the text to say what would be undone/redone, but I don't know
the GTK.
* app/gimpimage.c: new signal emitted by gimage:
UNDO_EVENT. gimp_image_undo_event() function to emit it.
* app/gimpimage.h: prototype for above.
* app/gimpimageP.h: pushing_undo_group member is now an undo_type,
not an int. Keep undo history widget here too (if created).
* app/menus.c: add "Edit/Undo history..." to image menu.
* app/undo.c: new types: enums undo_type and undo_state rather than
ints and magic numbers. All undo_pop_* and undo_free_*
functions made static. New static function
undo_type_to_name(). Issue undo event signals on various
important events (eg undo pushed, undo popped etc).
undo_push() now takes a "dirties_image" arg to say whether
image should be dirtied. Layer moves now dirty the image. A
couple of g_return_if_fails () on undo_pop and undo_redo to
assert we're not in the middle of an undo group.
undo_get_{undo,redo}_name() to peek at names of top items on
undo and redo stacks resp. undo_map_over_{undo,redo}_stack()
to run a function for each item or group on stack. Layer and
channel undos use symbolic names rather than 0 or 1. Array
mapping undo types to names.
* app/undo.h: split out undo types to undo_types.h. Prototypes
for functions described above. undo_event_t enum.
undo_history_new() prototype lives here too.
Random other fixes:
* app/gimpdrawable.c
* app/image_render.c: default labels in switches to keep egcs happy.
* app/nav_window.c: some fixes to (sort of) cope with image res !=
screen res. Still needs work to handle non-square pixels
properly.
* app/paths_dialog.c: bad idea to call gimp_image_dirty()
directly. Even though it's currently commented out.
