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.

* libgimp/gimpbrushmenu.c
* libgimp/gimpmenu.c
* libgimp/gimppatternmenu.c
* libgimp/gimpui.c
* libgimpbase/gimpenv.c: tons and tons of changes like "const
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.
