2004-06-23 Michael Natterer <mitch@gimp.org> * app/paint/gimpbrushcore.[ch]: added signal "set-brush" which is G_SIGNAL_RUN_LAST so we can connect before and after the default implementation. Moved the brush setting and outline invalidation stuff to its default implementation. Also remember the outline's width and height. Call gimp_brush_core_set_brush() from gimp_brush_core_invalidate_cache() so "set-brush" is emitted whenever a generated brush becomes dirty. * app/tools/gimppainttool.c (gimp_paint_tool_button_press): don't pause/resume but rather stop/start the draw_tool. Fixes straight line preview aretefacts. (gimp_paint_tool_oper_update): set the brush_core's brush before starting the draw_tool. (gimp_paint_tool_draw): never free the brush_core's cached brush outline because the brush_core does that by itself now. (gimp_paint_tool_set_brush) (gimp_paint_tool_set_brush_after): new callbacks which pause and resume the draw_tool. Fixes brush outline artefacts when modifying the current brush e.g. by using the mouse wheel.
