2003-02-05 Michael Natterer <mitch@gimp.org> Made GimpToolOptions a GimpContext subclass and objectified all tool options types. * app/core/core-types.h: replaced GimpToolOptionsNewFunc by GimpToolOptionsGUIFunc. * libgimpproxy/gimpproxytypes.h: regenerated. * app/core/gimppaintinfo.[ch]: added "GType paint_options_type". * app/core/gimptoolinfo.[ch]: added "GType tool_options_type", removed tool_info->context since GimpToolOptions are a GimpContext now. Added "gboolean use_context" as a temp_hack. * libgimptool/gimptooltypes.h: added the tool_options_type to the tool registering callback. * app/tools/tool_options.[ch]: is a real GimpContext subclass now. * app/paint/paint-types.h * app/paint/paint.c: added the paint_options_type to the paint registering stuff. * app/paint/gimppaintoptions.[ch]: is a real GimpToolOptions subclass now. * app/paint/Makefile.am * app/paint/gimpairbrushoptions.[ch] * app/paint/gimpcloneoptions.[ch] * app/paint/gimpconvolveoptions.[ch] * app/paint/gimpdodgeburnoptions.[ch] * app/paint/gimperaseroptions.[ch] * app/paint/gimpsmudgeoptions.[ch]: new files holding GimpPaintOptions subclasses. * app/paint/gimpairbrush.[ch] * app/paint/gimpclone.[ch] * app/paint/gimpconvolve.[ch] * app/paint/gimpdodgeburn.[ch] * app/paint/gimperaser.[ch] * app/paint/gimppaintbrush.c * app/paint/gimppaintcore.c * app/paint/gimppencil.[ch] * app/paint/gimpsmudge.[ch]: removed paint options stuff, lots of related changed & cleanups. * tools/pdbgen/pdb/paint_tools.pdb: changed accordingly. * app/pdb/paint_tools_cmds.c: regenerated. * app/tools/Makefile.am * app/tools/gimpblendoptions.[ch] * app/tools/gimpbucketfilloptions.[ch] * app/tools/gimpcolorpickeroptions.[ch] * app/tools/gimpcropoptions.[ch] * app/tools/gimpflipoptions.[ch] * app/tools/gimpinkoptions.[ch] * app/tools/gimpmagnifyoptions.[ch] * app/tools/gimpmeasureoptions.[ch] * app/tools/gimpmoveoptions.[ch] * app/tools/gimptextoptions.[ch] * app/tools/gimpvectoroptions.[ch]: new files holding the various tool options classes. * app/tools/selection_options.[ch] * app/tools/transform_options.[ch]: made them objects. * app/tools/paint_options.[ch]: contains only the paint_options GUI and reset stuff. * app/tools/tools-types.h: removed SelectionOptions typedef for now. * app/tools/[all tools]: removed the tool options stuff except some GUI constructors. Tons of related changes. * app/tools/tool_manager.[ch]: changed tool registration / restore / switching accordingly. * app/widgets/gimpdrawablelistview.c * app/widgets/gimpselectioneditor.c: changed accordingly.
