2001-11-08 Michael Natterer <mitch@gimp.org> * app/Makefile.am: build display/ before tools/. * app/devices.c: devices_check_change(): added all events which have a GdkDevice pointer. * app/gimpprogress.c: include "display-types.h" instead of "core-types.h". * app/core/Makefile.am * app/core/gimpdrawable-bucket-fill.[ch]: new files: the bucket_fill stuff taken from tools/gimpbucketfilltool.[ch]. * app/core/core-types.h: added "BucketFillMode". * app/core/gimpimage-mask-select.[ch]: cleanup. * app/core/gimpmarshal.list: added more marshallers for GimpTool's new signal signatures. * app/core/gimpmarshal.[ch]: regenerated. * app/display/Makefile.am * app/display/gimpdisplayshell-dnd.[ch] * app/display/gimpdisplayshell-layer-select.[ch]: new files: the canvas drop callbacks from gimpdisplayshell-callbacks.[ch] and the stuff formerly knows as gui/layer-select.[ch]. * app/display/gimpdisplay.h: don't include "gui/gui-types.h". * app/display/gximage.c: include "display-types.h". * app/display/gimpdisplay-foreach.c * app/display/gimpdisplayshell.[ch]: call gdsplay_delete(), don't destroy the shell widget. * app/gui/Makefile.am * app/gui/layer-select.[ch]: removed. * app/gui/gradients-commands.c: fixed "Save as POV" fprintf()s. * app/gui/preferences-dialog.c: removed the layer_select stuff because it is useless with the new preview system. * app/gui/tool-options-dialog.c: send the correct data to the close_callback. * app/gui/tools-commands.c: changed to follow the new gimp_tool_initialize() semantics (see below). Tool & canvas event handling chainsawing: * app/tools/tools-types.h: new struct GimpCoords which contains x, y, pressure, tilt etc. * app/display/gimpdisplayshell-callbacks.[ch]: added utility functions which transparently retreive the current event's GimpCoords or take it from the device directly if the event has none. Pass GimpCoords _in_image_coordinates_ to all tool functions. Most important: don't pass GdkEvents and display coordinates to tools any more. * app/tools/gimptool.[ch]: changed virtual functions to take GimpCoords, time and state separately instead of GdkEvents. * app/tools/gimpbezierselecttool.c * app/tools/gimpblendtool.c * app/tools/gimpbucketfilltool.[ch] * app/tools/gimpbycolorselecttool.c * app/tools/gimpclonetool.c * app/tools/gimpcolorpickertool.c * app/tools/gimpconvolvetool.c * app/tools/gimpcroptool.[ch] * app/tools/gimpcurvestool.c * app/tools/gimpdodgeburntool.c * app/tools/gimpdrawtool.c * app/tools/gimpeditselectiontool.[ch] * app/tools/gimperasertool.c * app/tools/gimpfliptool.c * app/tools/gimpfreeselecttool.[ch] * app/tools/gimpfuzzyselecttool.c * app/tools/gimpinktool.c * app/tools/gimpiscissorstool.c * app/tools/gimpmagnifytool.c * app/tools/gimpmeasuretool.c * app/tools/gimpmovetool.c * app/tools/gimppainttool.c * app/tools/gimppathtool.[ch] * app/tools/gimprectselecttool.c * app/tools/gimprotatetool.c * app/tools/gimpselectiontool.[ch] * app/tools/gimpsmudgetool.c * app/tools/gimptexttool.c * app/tools/gimptransformtool.[ch] * app/tools/path_tool.[ch] * app/tools/selection_options.c: tons and tons of changes: - changed to use the new virtual function parameters. - removed zillions of gdisplay_untransform_coords(). - get the active drawable's offsets manually in many cases. (questionable, but IMHO ok because it's obvious and not simply a "TRUE" passed to some function) - reordered some functions to be consistent across tools. - some tools had to be changed to work on image coords, not display ones (esp. crop). - fixed strange rotate tool behaviour which should be backported to stable. - some stuff i came across. - indentation and other paranoia. - rounding of coordinated may be broken in some tools. - new bugs guaranteed. * app/tools/tool_manager.[ch]: new semantic of tool_manager_initialize_active() (looked at the places where it was used from and put common code together). Should be a bit better now :) * app/tools/gimpblendtool.c * app/tools/transform_options.c: use the new GTK+ feature that a widget (toggle button) can be a frame's title for this tools' tool options. * app/widgets/widgets-types.h: stuff. * themes/Default/gtkrc: s/GtkDialog/GimpDialog/. * tools/pdbgen/Makefile.am: don't scan tools/gimpbucketfilltool.h any more. * tools/pdbgen/enums.pl: regenerated. * tools/pdbgen/pdb/tools.pdb: changed bucket_fill wrapper. * app/pdb/tools_cmds.c: regenerated.
