2001-11-01 Michael Natterer <mitch@gimp.org> * app/display/Makefile.am * app/display/gimpdisplay-callbacks.[ch] * app/display/gimpdisplay-render.[ch] * app/display/gimpdisplay-scale.[ch] * app/display/gimpdisplay-scroll.[ch]: removed and added as gimpdisplayshell-foo.[ch] because they are all methods of the shell. * app/display/gimpdisplay.[ch] * app/display/gimpdisplayshell.[ch]: moved the "offset" and "size" variables from GimpDisplay to GimpDisplayShell. GimpDisplay should know nothing about screen coordinates. The gdisplay_[un]transform_foo() methods are still part of GimpDisplay but will be moved to GimpDisplayShell as soon as the tools' vitrual functions speak in image coordinates instead of GdkEvents. * app/display/gimpdisplayshell-callbacks.[ch]: prefixed all functions with gimp_display_shell_*. Moved some stuff to a "realize" callback File still has to be renamed. * app/display/gimpdisplay-foreach.[ch]: removed gdisplays_shrink_wrap(). * app/gui/menus.c * app/gui/view-commands.[ch] * app/display/gimpdisplayshell-scale.[ch]: implemented "Zoom to Fit Window" function (#57670). * app/nav_window.c * app/display/gimpdisplay-handlers.c * app/display/gimpdisplayshell-render.[ch] * app/display/gimpdisplayshell-scale.[ch] * app/display/gimpdisplayshell-scroll.[ch] * app/gui/colormap-dialog.c * app/gui/gui.c * app/gui/preferences-dialog.c * app/tools/gimpmagnifytool.c * app/tools/gimpmovetool.c * app/widgets/gimppreview.c: changed according to variable and filename changes. * app/tools/tool_manager.c: tool_manager_select_tool(): send the active tool a "HALT" command before selecting the new one. Fixes stale tool dialogs which were there because some other hack was removed (This is IMHO the right place to shut down the active tool). * app/tools/gimpcroptool.c: don't shrink wrap after cropping but let gimprc.allow_resize_windows decide. * app/tools/gimpselectiontool.c: gimage_mask_value() takes image, not screen coordinates. A good example of how braindead it is to pass GdkEvents to tools :-) Fixes incorrect cursor and oper update of the selection tools. * app/tools/gimptransformtool.c * app/undo.c: removed (#if 0 for now) some strange code which did manual exposing of GimpDisplayShell areas. This was definitely a hack and should not be there given the image emits correct "update" signals.
