GI.Gtk.Objects.Bin

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.

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

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

noBin :: Maybe Bin

A convenience alias for Nothing :: Maybe Bin.

Methods

getChild

binGetChild

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.
