"""Drag-and-drop support for Tkinter.
|
||||
|
||||
This is very preliminary. I currently only support dnd *within* one
|
||||
application, between different windows (or within the same window).
|
||||
|
||||
I an trying to make this as generic as possible -- not dependent on
|
||||
the use of a particular widget or icon type, etc. I also hope that
|
||||
this will work with Pmw.
|
||||
|
||||
To enable an object to be dragged, you must create an event binding
|
||||
for it that starts the drag-and-drop process. Typically, you should
|
||||
bind <ButtonPress> to a callback function that you write. The function
|
||||
should call Tkdnd.dnd_start(source, event), where 'source' is the
|
||||
object to be dragged, and 'event' is the event that invoked the call
|
||||
(the argument to your callback function). Even though this is a class
|
||||
instantiation, the returned instance should not be stored -- it will
|
||||
be kept alive automatically for the duration of the drag-and-drop.
|
||||
|
||||
When a drag-and-drop is already in process for the Tk interpreter, the
|
||||
call is *ignored*; this normally averts starting multiple simultaneous
|
||||
dnd processes, e.g. because different button callbacks all
|
||||
dnd_start().
|
||||
|
||||
The object is *not* necessarily a widget -- it can be any
|
||||
application-specific object that is meaningful to potential
|
||||
drag-and-drop targets.
|
||||
|
||||
Potential drag-and-drop targets are discovered as follows. Whenever
|
||||
the mouse moves, and at the start and end of a drag-and-drop move, the
|
||||
Tk widget directly under the mouse is inspected. This is the target
|
||||
widget (not to be confused with the target object, yet to be
|
||||
determined). If there is no target widget, there is no dnd target
|
||||
object. If there is a target widget, and it has an attribute
|
||||
dnd_accept, this should be a function (or any callable object). The
|
||||
function is called as dnd_accept(source, event), where 'source' is the
|
||||
object being dragged (the object passed to dnd_start() above), and
|
||||
'event' is the most recent event object (generally a <Motion> event;
|
||||
it can also be <ButtonPress> or <ButtonRelease>). If the dnd_accept()
|
||||
function returns something other than None, this is the new dnd target
|
||||
object. If dnd_accept() returns None, or if the target widget has no
|
||||
dnd_accept attribute, the target widget's parent is considered as the
|
||||
target widget, and the search for a target object is repeated from
|
||||
there. If necessary, the search is repeated all the way up to the
|
||||
root widget. If none of the target widgets can produce a target
|
||||
object, there is no target object (the target object is None).
|
||||
|
||||
The target object thus produced, if any, is called the new target
|
||||
object. It is compared with the old target object (or None, if there
|
||||
was no old target widget). There are several cases ('source' is the
|
||||
source object, and 'event' is the most recent event object):
|
||||
|
||||
- Both the old and new target objects are None. Nothing happens.
|
||||
|
||||
- The old and new target objects are the same object. Its method
|
||||
dnd_motion(source, event) is called.
|
||||
|
||||
- The old target object was None, and the new target object is not
|
||||
None. The new target object's method dnd_enter(source, event) is
|
||||
called.
|
||||
|
||||
- The new target object is None, and the old target object is not
|
||||
None. The old target object's method dnd_leave(source, event) is
|
||||
called.
|
||||
|
||||
- The old and new target objects differ and neither is None. The old
|
||||
target object's method dnd_leave(source, event), and then the new
|
||||
target object's method dnd_enter(source, event) is called.
|
||||
|
||||
Once this is done, the new target object replaces the old one, and the
|
||||
Tk mainloop proceeds. The return value of the methods mentioned above
|
||||
is ignored; if they raise an exception, the normal exception handling
|
||||
mechanisms take over.
|
||||
|
||||
The drag-and-drop processes can end in two ways: a final target object
|
||||
is selected, or no final target object is selected. When a final
|
||||
target object is selected, it will always have been notified of the
|
||||
potential drop by a call to its dnd_enter() method, as described
|
||||
above, and possibly one or more calls to its dnd_motion() method; its
|
||||
dnd_leave() method has not been called since the last call to
|
||||
dnd_enter(). The target is notified of the drop by a call to its
|
||||
method dnd_commit(source, event).
|
||||
|
||||
If no final target object is selected, and there was an old target
|
||||
object, its dnd_leave(source, event) method is called to complete the
|
||||
dnd sequence.
|
||||
|
||||
Finally, the source object is notified that the drag-and-drop process
|
||||
is over, by a call to source.dnd_end(target, event), specifying either
|
||||
the selected target object, or None if no target object was selected.
|
||||
The source object can use this to implement the commit action; this is
|
||||
sometimes simpler than to do it in the target's dnd_commit(). The
|
||||
target's dnd_commit() method could then simply be aliased to
|
||||
dnd_leave().
|
||||
|
||||
At any time during a dnd sequence, the application can cancel the
|
||||
sequence by calling the cancel() method on the object returned by
|
||||
dnd_start(). This will call dnd_leave() if a target is currently
|
||||
active; it will never call dnd_commit().
