GI.Gdk.Interfaces.DragSurface

A GdkDragSurface is an interface for surfaces used during DND.

Exported types

newtype DragSurface

Memory-managed wrapper type.

Constructors

type ParentTypes DragSurface

Defined in GI.Gdk.Interfaces.DragSurface

type ParentTypes DragSurface = '[Surface, Object]

class (GObject o, IsDescendantOf DragSurface o) => IsDragSurface o

Type class for types which can be safely cast to DragSurface, for instance with toDragSurface.

Instances

(GObject o, IsDescendantOf DragSurface o) => IsDragSurface o

Defined in GI.Gdk.Interfaces.DragSurface

toDragSurface :: (MonadIO m, IsDragSurface o) => o -> m DragSurface

Cast to DragSurface, for types for which this is known to be safe. For general casts, use castTo.
