Detailed Description

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.
