Description

The Bin widget is a container with just one child. It is not very useful itself, but it is useful for deriving subclasses, since it provides common code needed for handling a single child widget.

Many GTK+ widgets are subclasses of Bin, including Window, Button, Frame, HandleBox or ScrolledWindow.

Synopsis

newtype Bin = Bin (ManagedPtr Bin)
class GObject o => IsBin o
toBin :: (MonadIO m, IsBin o) => o -> m Bin
noBin :: Maybe Bin
binGetChild :: (HasCallStack, MonadIO m, IsBin a) => a -> m (Maybe Widget)

Exported types

newtype Bin Source #

Memory-managed wrapper type.

Constructors

toBin :: (MonadIO m, IsBin o) => o -> m Bin Source #

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

noBin :: Maybe Bin Source #

A convenience alias for Nothing :: Maybe Bin.

Methods

getChild

binGetChild Source #

Arguments

:: (HasCallStack, MonadIO m, IsBin a)
=> a	`bin`: a `Bin`
-> m (Maybe Widget)	Returns: the child of `bin`, or `Nothing` if it does not have a child.

Gets the child of the Bin, or Nothing if the bin contains no child widget. The returned widget does not have a reference added, so you do not need to unref it.
