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 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 event; +it can also be or ). 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().

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 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 event; -it can also be or ). 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().
