\section{Detailed Description}{These functions provide a low level interface for drag and drop.
The X backend of GDK supports both the Xdnd and Motif drag and drop protocols
transparently, the Win32 backend supports the WM_DROPFILES protocol.
GTK+ provides a higher level abstraction based on top of these functions,
and so they are not normally needed in GTK+ applications.
See the Drag and Drop section of
the GTK+ documentation for more information.}
\section{Structures}{\describe{\item{\verb{GdkDragContext}}{
A \code{GdkDragContext} holds information about a
drag in progress. It is used on both source and destination sides.
\describe{
\item{\verb{protocol}}{[\code{\link{GdkDragProtocol}}] the parent instance}
\item{\verb{isSource}}{[logical] the DND protocol which governs this drag.}
\item{\verb{sourceWindow}}{[\code{\link{GdkWindow}}] \code{TRUE} if the context is used on the source side.}
\item{\verb{destWindow}}{[\code{\link{GdkWindow}}] the source of this drag.}
\item{\verb{targets}}{[list] the destination window of this drag.}
\item{\verb{actions}}{[\code{\link{GdkDragAction}}] a list of targets offered by the source.}
\item{\verb{suggestedAction}}{[\code{\link{GdkDragAction}}] a bitmask of actions proposed by the source when
\code{suggested.action} is \code{GDK_ACTION_ASK}.}
\item{\verb{action}}{[\code{\link{GdkDragAction}}] the action suggested by the source.}
\item{\verb{startTime}}{[numeric] the action chosen by the destination.}
}
}}}
\section{Convenient Construction}{\code{gdkDragContext} is the equivalent of \code{\link{gdkDragContextNew}}.}
\section{Enums and Flags}{\describe{
\item{\verb{GdkDragProtocol}}{
Used in \code{\link{GdkDragContext}} to indicate the protocol according to
which DND is done.
\describe{
\item{\verb{motif}}{The Motif DND protocol.}
\item{\verb{xdnd}}{The Xdnd protocol.}
\item{\verb{rootwin}}{An extension to the Xdnd protocol for
unclaimed root window drops.}
\item{\verb{none}}{no protocol.}
\item{\verb{win32-dropfiles}}{The simple WM_DROPFILES protocol.}
\item{\verb{ole2}}{The complex OLE2 DND protocol (not implemented).}
\item{\verb{local}}{Intra-application DND.}
}
}
\item{\verb{GdkDragAction}}{
Used in \code{\link{GdkDragContext}} to indicate what the destination
should do with the dropped data.
\describe{
\item{\verb{default}}{Means nothing, and should not be used.}
\item{\verb{copy}}{Copy the data.}
\item{\verb{move}}{Move the data, i.e. first copy it, then delete
it from the source using the DELETE target of the X selection protocol.}
\item{\verb{link}}{Add a link to the data. Note that this is only
useful if source and destination agree on what it means.}
\item{\verb{private}}{Special action which tells the source that the
destination will do something that the source doesn't understand.}
\item{\verb{ask}}{Ask the user what to do with the data.}
}
