* gui_canvas.h - GUI, canvas
|
|
|
|
|
*
|
Dragging a frame into the canvas now works. It's built on top of the frame
tool, with all the old code still around, so the code paths are a bit obscure.
- gui_frame_drag.c: use GTK_DEST_DEFAULT_MOTION instead of
GTK_DEST_DEFAULT_HIGHLIGHT
- gui_frame_drag.c: put meat on the frame and canvas drag and drop skeleton
- gui_frame_drag.c (setup_frame_drag, setup_canvas_drag): use GDK_ACTION_COPY
instead of GDK_ACTION_PRIVATE
- gui_frame_drag.h, gui_frame_drag.c (is_dragging_anything): new helper
function to check if we're dragging anything, without specifying what
- gui_canvas.h, gui_canvas.c: added thin interface layer between gui_frame.c
and gui_tool.c
- gui_canvas.c (enter_notify_event, leave_notify_event): return FALSE so that
other widgets can get the events, too
- gui_tool.h, gui_tool.c (tool_hover): return whether we found anything to
hover on
- gui_tool.h, gui_tool.c: added interface for dropping a frame on the canvas
