2001-07-07 Michael Natterer <mitch@gimp.org> * app/Makefile.am * app/context_manager.[ch]: removed. * app/app_procs.c: call tool_mananger instead of context_manager functions, pass "the_gimp" to some more functions. * app/drawable.[ch]: pass a GimpContext to drawable_fill(). * app/errors.c: behave according to "stack_trace_mode" when using the debugging signal handler. * app/gimprc.[ch]: removed the core/ config variables. * app/selection.c: set the selection's state to INVISIBLE in selection_pause(). * app/core/Makefile.am * app/core/gimpcoreconfig.[ch]: new files (the configuration variables used by core/). * app/core/gimpcontext.[ch]: removed the global contexts (user, default, ...) and their functions. It's no longer possible to pass NULL to the context functions to manipulate the current context (gimpcontext.c doesn't know the current context any more). * app/core/gimp.[ch]: added them here. The functions are now called gimp_[set|get]_*_context(). Added gimp_create_context() which is the only function to create contexts now. * app/gui/dialogs.[ch] * app/gui/gui.[ch]: pass "gimp" to all functions. * app/tools/tool_manager.[ch] * app/tools/tools.[ch]: pass "gimp" to lots of functions. Added the "global_tool_context" logic and the global/non-global paint options switching from the context_manager. Pass "gimp" to all tools' "register" functions. * app/tools/*: changed accordingly. * app/devices.c * app/disp_callbacks.c * app/file-open.[ch] * app/file-save.c * app/gdisplay.c * app/gimage.c * app/libgimp_glue.c * app/module_db.c * app/nav_window.c * app/plug_in.c * app/qmask.c * app/undo.c * app/base/base-config.c * app/core/gimpbrushpipe.c * app/core/gimpdrawable-offset.c * app/core/gimpgradient.c * app/core/gimpimage-duplicate.c * app/core/gimpimage-mask.c * app/core/gimpimage-new.c * app/core/gimpimage.c * app/core/gimppalette.c * app/core/gimptoolinfo.[ch] * app/core/gimpundo.c * app/gui/brush-select.c * app/gui/channels-commands.c * app/gui/color-area.c * app/gui/dialogs-constructors.c * app/gui/file-new-dialog.c * app/gui/file-open-dialog.c * app/gui/gradient-editor.c * app/gui/gradient-select.c * app/gui/info-window.c * app/gui/layers-commands.c * app/gui/menus.c * app/gui/palette-editor.c * app/gui/palette-import-dialog.c * app/gui/palette-select.c * app/gui/paths-dialog.c * app/gui/pattern-select.c * app/gui/preferences-dialog.c * app/gui/resize-dialog.c * app/gui/test-commands.c * app/gui/tool-options-dialog.c * app/gui/toolbox.c * app/gui/tools-commands.c * app/xcf/xcf-load.c * app/xcf/xcf-save.c * app/widgets/gimpchannellistview.c * app/widgets/gimpdnd.c * app/widgets/gimpdrawablelistview.[ch] * app/widgets/gimpimagedock.c * app/widgets/gimplayerlistview.c * app/pdb/brushes_cmds.c * app/pdb/drawable_cmds.c * app/pdb/gradient_select_cmds.c * app/pdb/gradients_cmds.c * app/pdb/palette_cmds.c * app/pdb/patterns_cmds.c * app/pdb/procedural_db.c * tools/pdbgen/pdb/brushes.pdb * tools/pdbgen/pdb/drawable.pdb * tools/pdbgen/pdb/gradient_select.pdb * tools/pdbgen/pdb/gradients.pdb * tools/pdbgen/pdb/palette.pdb * tools/pdbgen/pdb/patterns.pdb: changed accordingly: remove usage of gimp_context_[get|set]_*(NULL), create contexts with gimp_create_context(). Get the user/current context with gimp_get_[user|current]_context(). Added/removed access to the global "the_gimp" variable in some places. Get the core's config variables from "core_config".
