GTK+ has a rich set of functions for doing inter-process
communication via the drag-and-drop metaphor. GTK+
can do drag-and-drop (DND) via multiple protocols.
The currently supported protocols are the Xdnd and
Motif protocols.
As well as the functions listed here, applications
may need to use some facilities provided for
Selections.
Also, the Drag and Drop API makes use of signals
in the GtkWidget class.Enums and Flags
GtkDestDefaults-
The
GtkDestDefaults enumeration specifies the various
types of action that will be taken on behalf
of the user for a drag destination site.
motion- If set for a widget, GTK+, during a drag over this
widget will check if the drag matches this widget's
list of possible targets and actions.
GTK+ will then call
gdkDragStatus as appropriate. highlight- If set for a widget, GTK+ will draw a highlight on
this widget as long as a drag is over this widget
and the widget drag format and action are acceptable.
drop- If set for a widget, when a drop occurs, GTK+ will
will check if the drag matches this widget's
list of possible targets and actions. If so,
GTK+ will call
gtkDragGetData on behalf
of the widget. Whether or not the drop is successful,
GTK+ will call gtkDragFinish. If the action
was a move, then if the drag was successful, then
TRUE will be passed for the delete parameter
to gtkDragFinish. all- If set, specifies that all default actions should
be taken.
GtkTargetFlags-
The
GtkTargetFlags enumeration is used to specify
constraints on an entry in a GtkTargetTable.
app- If this is set, the target will only be selected
for drags within a single application.
widget- If this is set, the target will only be selected
for drags within a single widget.
