2001-10-29 Michael Natterer <mitch@gimp.org> Cleanup weekend... * app/app_procs.c: pass "no_interface" to gimp_new(). * app/core/gimp.[ch]: added "gboolean no_interface" and the load_procs and save_procs GSLists. * app/core/gimptoolinfo.[ch]: added a "Gimp" pointer to the GimpToolInfo object so more functions find their context without accessing the global "the_gimp" variable. * app/display/display-types.h: removed the GDisplay -> GimpDisplay typedef. * app/display/gimpdisplay.c: look at gimp->no_interface, don't include "appenv.h". * app/file/file-open.[ch] * app/file/file-save.[ch]: don't use "the_gimp" any more. Instead, pass around lots of "Gimp" pointers. Removed the global load_procs and save_procs variables here. Use access() to find out whether a file is readable/writable, removed the manual voodoo and it's Win32 wrappers. Added an optional (can be NULL) "PlunInProcDef" parameter to file_save(), removed file_save_with_proc(). * app/gui/menus.c: Use the unused "gpointer data" parameter of the GtkItemFactory callbacks to pass a "Gimp" pointer to all of them. This reduces the usage of the global "the_gimp" hack to zero in app/gui/... yeah. * app/gui/channels-commands.c * app/gui/edit-commands.c * app/gui/file-commands.c * app/gui/image-commands.c * app/gui/layers-commands.c * app/gui/palettes-commands.c * app/gui/select-commands.c * app/gui/test-commands.c * app/gui/tools-commands.c * app/gui/view-commands.c: use the passed "Gimp" pointer. * app/gui/color-area.[ch] * app/gui/convert-dialog.c * app/gui/dialogs-constructors.c * app/gui/file-new-dialog.[ch] * app/gui/file-open-dialog.[ch] * app/gui/file-save-dialog.[ch] * app/gui/gui.c * app/gui/info-window.[ch] * app/gui/module-browser.[ch] * app/gui/palette-editor.c * app/gui/palette-import-dialog.[ch] * app/gui/paths-dialog.c * app/gui/preferences-dialog.[ch] * app/gui/resize-dialog.[ch] * app/gui/tool-options-dialog.[ch] * app/gui/toolbox.c: pass around lots more "Gimp" and "GimpContext" pointers and don't use "the_gimp" any more. * app/tools/gimptool.h: added a pointer to the corresponding GimpToolInfo object (which in turn has a pointer to a Gimp). * app/tools/tool_manager.[ch]: set the pointer after creating the tool object. Removed tool_manager_get_info_by_tool() as there is a tool->tool_info pointer now. * app/tools/gimpbezierselecttool.c * app/tools/gimpblendtool.c * app/tools/gimpbrightnesscontrasttool.c * app/tools/gimpclonetool.c * app/tools/gimpcolorbalancetool.c * app/tools/gimpcolorpickertool.c * app/tools/gimpconvolvetool.c * app/tools/gimpcroptool.c * app/tools/gimpcurvestool.c * app/tools/gimpdodgeburntool.c * app/tools/gimpdrawtool.c * app/tools/gimpeditselectiontool.c * app/tools/gimpellipseselecttool.c * app/tools/gimperasertool.c * app/tools/gimpfliptool.c * app/tools/gimphistogramtool.c * app/tools/gimphuesaturationtool.c * app/tools/gimpinktool.c * app/tools/gimplevelstool.c * app/tools/gimpmagnifytool.c * app/tools/gimpmeasuretool.c * app/tools/gimpmovetool.c * app/tools/gimppainttool.c * app/tools/gimppathtool.c * app/tools/gimpperspectivetool.c * app/tools/gimpposterizetool.c * app/tools/gimprectselecttool.c * app/tools/gimprotatetool.c * app/tools/gimpscaletool.c * app/tools/gimpsheartool.c * app/tools/gimptexttool.c * app/tools/gimpthresholdtool.c * app/tools/path_tool.c * app/tools/xinput_airbrush.c: s/GDisplay/GimpDisplay/g. Use tool->tool_info and tool_info->gimp in some places to get rid of using "the_gimp". Removing the remaining ones involves changing the tool options system and is scheduled next... * app/widgets/gimpdnd.c * app/widgets/gimpdocumentview.c: pass a "Gimp" pointer to all file_open_*() functions. * app/gdisplay_color.[ch] * app/gdisplay_color_ui.[ch] * app/image_map.[ch] * app/nav_window.[ch] * app/path.c * app/path_bezier.c * app/path_transform.h * app/qmask.[ch]: s/GDisplay/GimpDisplay/g * tools/pdbgen/pdb/fileops.pdb: load_procs and save_procs are members of the "Gimp" object now. * tools/pdbgen/pdb/plug_in.pdb: use gimp->no_interface, don't include "appenv.h". * app/pdb/fileops_cmds.c * app/pdb/plug_in_cmds.c: regenerated.
