2001-02-21 Michael Natterer <mitch@gimp.org> Made the tool system work again and integrated it back with the GimpContext. It's a hack between old, new and freshly hacked stuff. There are still lots of warnings but at least we can switch tools again. * app/tools/Makefile.am * app/tools/gimptoolinfo.[ch]: resurrected as real object. The GimpToolInfo objects are derived from GimpData, which gives us the tool icon stuff for free. Also, we need a list of _objects_ which is allocated all the time. All tools are required to have a "register" function which registers themselves with the list of GimpToolInfo objects which is maintained by the tool manager. * app/tools/tool.[ch]: made a real GtkObject with properly named functions out of it. The former "active_tool_control" is of course not the default implementation of the tool's "control" method but a hack _around_ it, so it went to the tool manager. * app/tools/color_picker.[ch] * app/tools/measure.[ch]: ditto. Added "register" functions and "destroy" implementations so the tools go away after use. * app/tools/tool_manager.[ch]: badly hacked at the moment to keep both the list of class structures _and_ the tool info list. * app/tools/tools.c: call the tools' register functions. * app/gimpcontext.[ch]: store a pointer to a GimpToolInfo object as "active_tool" in the context, so we're independent of tools being allocated or not. It's treated just like a brush or pattern now. * app/gimpdnd.[ch]: made tool DND work like all other DND types. * app/devices.[ch]: also here: the tool is just a normal data object now, resulting in removal of lots of code. * app/commands.c * app/context_manager.c: updated the tool select and context stuff to work again. * app/toolbox.c: removed the old pixmap buttons and put GimpPreviews inside the tool buttons. Still needs an own preview type to look nice. * app/disp_callbacks.c * app/about_dialog.c * app/app_procs.c * app/appenums.h * app/apptypes.h * app/gimage.c * app/gimppalette.c * app/gimppreview.c * app/gimprc.c * app/info_window.c * app/menus.c * app/palette_select.h * app/scale.c * app/scroll.c: lots of changes to make it work again.
