gdkDragContext()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.Enums and Flags
GdkDragProtocol-
Used in
GdkDragContext to indicate the protocol according to
which DND is done.
motif- The Motif DND protocol.
xdnd- The Xdnd protocol.
rootwin- An extension to the Xdnd protocol for
unclaimed root window drops.
none- no protocol.
win32-dropfiles- The simple WM_DROPFILES protocol.
ole2- The complex OLE2 DND protocol (not implemented).
local- Intra-application DND.
GdkDragAction-
Used in
GdkDragContext to indicate what the destination
should do with the dropped data.
default- Means nothing, and should not be used.
copy- Copy the data.
move- Move the data, i.e. first copy it, then delete
it from the source using the DELETE target of the X selection protocol.
link- Add a link to the data. Note that this is only
useful if source and destination agree on what it means.
private- Special action which tells the source that the
destination will do something that the source doesn't understand.
ask- Ask the user what to do with the data.
