and a default key_press() handler that emits CONFIRM, CANCEL and RESET
responses. Remove code with the same purpose from all subclasses.
Change tools feed key_press() to the widget and connect to its
"response" instead of implementing key_press() themselves. This will
only be better and less code after the tool side of this is done
generically.
Rename gimp_tool_widget_snap_offsets() to set_snap_offsets(),
and add gimp_tool_widget_get_snap_offsets().
Also rename gimp_tool_widget_status() to set_status(), and
add new function and signal set_status_coords().
so widgets can return which handle was clicked. The values boolean
semantics stay the same so if(retval) gives the same result. This is
useful for the upcoming transform tool widgets.
which encapsulates a bunch of GimpCanvasItems plus their interaction,
using GimpTool-like virtual functions like button_press(),
button_release() motion() etc. Also has GimpDrawTool-like API to
manage the canvas items of its subclasses.
