2007-02-27 Michael Natterer <mitch@gimp.org> * app/tools/gimptoolcontrol.[ch]: added "gboolean wants_click" member and getters/setters. * app/tools/gimptool.[ch] (struct GimpTool): added members in_click_distance, press_coords and press_time. (gimp_tool_button_press): if the tool wants click events, record press_coords and press_time. (gimp_tool_motion): check if we are still in click distance. (gimp_tool_button_release): ditto. If we are still in click distance, synthesize a motion event back to the recorded press_coords and send the tool release_type = CLICK. (gimp_tool_check_click_distance): utility function which checks the current coords and time against the recorded ones, using gtk-double-click-time and gtk-double-click-distance as thresholds. * app/tools/gimpcroptool.c * app/tools/gimprectangleselecttool.c: request click events and handle them. * app/tools/gimprectangletool.[ch]: handle click events. Removed gimp_rectangle_tool_no_movement(). svn path=/trunk/; revision=22016
