	13	\index{wxDragResult}wxDragResult is defined as follows:
	14
	15	{\small\begin{verbatim}
	16	enum wxDragResult
	17	{
	18	wxDragError, // error prevented the d&d operation from completing
	19	wxDragNone, // drag target didn't accept the data
	20	wxDragCopy, // the data was successfully copied
	21	wxDragMove, // the data was successfully moved
	22	wxDragCancel // the operation was cancelled by user (not an error)

	34	\membersection{wxDropSource::wxDropSource}\label{wxdropsourcewxdropsource}
	35
	36	\func{}{wxDropSource}{\param{wxWindow }{*win = NULL}}
	37
	38	Default/wxGTK-specific constructor. If you use the default constructor you must
	39	call \helpref{wxDropSource::SetData}{wxdropsourcesetdata} later.
	40
	41	{\it win} is required by wxGTK and therefore should always be set.
	42
	43	\func{}{wxDropSource}{\param{wxDataObject }{\&data}, \param{wxWindow }{*win = NULL}}
	44
	45	\wxheading{Parameters}
	46
	47	\docparam{data}{A reference to the \helpref{data object}{wxdataobject} associated with the drop source.}
	48
	49	\docparam{win}{Only used by wxGTK. TODO}

	53	\func{virtual }{\destruct{wxDropSource}}{\void}
	54
	55	\membersection{wxDropSource::SetData}\label{wxdropsourcesetdata}
	56
	57	\func{void}{SetData}{\param{wxDataObject }{\&data}}
	58
	59	Sets the data \helpref{data object}{wxdataobject} associated with the drop source.
	60
	61	\membersection{wxDropSource::DoDragDrop}\label{wxdropsourcedodragdrop}
	62
	63	\func{virtual wxDragResult}{DoDragDrop}{\param{bool }{bAllowMove = FALSE}}
	64
	65	Do it (call this in response to a mouse button press, for example).
	66
	67	If {\bf bAllowMove} is FALSE, data can only be copied. Under GTK, data
	68	is always copied.
	69
	70	\membersection{wxDropSource::GiveFeedback}\label{wxdropsourcegivefeedback}
	71
	72	\func{virtual bool}{GiveFeedback}{\param{wxDragResult }{effect}, \param{bool }{bScrolling}}
	73
	74	Overridable: you may give some custom UI feedback during the drag and drop operation
	75	in this function. It is called on each mouse move, so your implementation must not be too
	76	slow.
	77
	78	\wxheading{Parameters}
	79
	80	\docparam{effect}{The effect to implement. One of wxDragCopy, wxDragMove. MSW only. }
	81
	82	\docparam{bScrolling}{TRUE if the window is scrolling. MSW only. }
	83
	84	\wxheading{Return value}
	85
	86	Return FALSE if you want default feedback, or TRUE if you implement your own
	87	feedback.
