GI.Gdk.Interfaces.DragSurface

A DragSurface is an interface implemented by GdkSurfaces used during a DND operation.

Exported types

newtype DragSurface

Memory-managed wrapper type.

Constructors

DragSurface (ManagedPtr DragSurface)

Instances

Eq DragSurface

Defined in GI.Gdk.Interfaces.DragSurface

Methods

(==) :: DragSurface -> DragSurface -> Bool

(/=) :: DragSurface -> DragSurface -> Bool

IsGValue DragSurface

Convert DragSurface to and from GValue with toGValue and fromGValue.

Defined in GI.Gdk.Interfaces.DragSurface

Methods

toGValue :: DragSurface -> IO GValue

fromGValue :: GValue -> IO DragSurface

ManagedPtrNewtype DragSurface

Defined in GI.Gdk.Interfaces.DragSurface

Methods

toManagedPtr :: DragSurface -> ManagedPtr DragSurface

TypedObject DragSurface

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.
