2002-11-14 Michael Natterer <mitch@gimp.org> Transform tool cleanup: * libgimptool/gimptoolenums.[ch]: removed the TransformState enum. * app/tools/gimptransformtool.[ch]: don't dispatch everything through the transform() virtual function. Added new vitrual functions dialog(), prepare(), motion() and recalc(). Do only the actual transform in transform(). Moved lots of logic which was duplicated in each subclass' transform() here. Cleanup. * app/tools/gimpfliptool.c * app/tools/gimpperspectivetool.c * app/tools/gimprotatetool.c * app/tools/gimpscaletool.c * app/tools/gimpsheartool.c: changed accordingly: moved code from transform() to the other method imlementations. Removed duplicated logic which is now done by our parent class. Makes everything smaller and more readable. InfoDialog cleanup: * app/gui/info-dialog.c: removed the "delete_event" callback so InfoDialog users can decide themselves what to do. * app/gui/info-window.c * app/tools/gimpmeasuretool.c: changed accordingly. * app/tools/gimpcolorpickertool.c: ditto. Moved info_dialog creation to a utility function to improve code readbility. * app/tools/gimpcroptool.c: ditto. Added a "Cancel" button which really cancels the tool instead of just hiding the dialog. * app/tools/gimptransformtool.c: added a "Cancel" button here too.
