Entry.setIconDragSource

void setIconDragSource(gtk.types.EntryIconPosition iconPos,  gtk.target_list.TargetList targetList,  gdk.types.DragAction actions)

Sets up the icon at the given position so that GTK+ will start a drag operation when the user clicks and drags the icon.

To handle the drag operation, you need to connect to the usual #GtkWidget::drag-data-get (or possibly #GtkWidget::drag-data-delete) signal, and use [gtk.entry.Entry.getCurrentIconDragSource] in your signal handler to find out if the drag was started from an icon.

By default, GTK+ uses the icon as the drag icon. You can use the #GtkWidget::drag-begin signal to set a different icon. Note that you have to use g_signal_connect_after() to ensure that your signal handler gets executed after the default handler.

Parameters

`iconPos`	icon position
`targetList`	the targets (data formats) in which the data can be provided
`actions`	a bitmask of the allowed drag actions
