GI.Gtk.Objects.LayoutChild

LayoutChild is the base class for objects that are meant to hold layout properties. If a LayoutManager has per-child properties, like their packing type, or the horizontal and vertical span, or the icon name, then the layout manager should use a LayoutChild implementation to store those properties.

A LayoutChild instance is only ever valid while a widget is part of a layout.

class (GObject o, IsDescendantOf LayoutChild o) => IsLayoutChild o

Type class for types which can be safely cast to LayoutChild, for instance with toLayoutChild.

Instances

(GObject o, IsDescendantOf LayoutChild o) => IsLayoutChild o

toLayoutChild :: (MonadIO m, IsLayoutChild o) => o -> m LayoutChild

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

getChildWidget

layoutChildGetChildWidget

Arguments

:: (HasCallStack, MonadIO m, IsLayoutChild a)

=> a

layoutChild: a LayoutChild

-> m Widget

Returns: a Widget

Retrieves the Widget associated to the given layoutChild.

getLayoutManager

layoutChildGetLayoutManager

Arguments

:: (HasCallStack, MonadIO m, IsLayoutChild a)

=> a

layoutChild: a LayoutChild

-> m LayoutManager

Returns: a LayoutManager

Retrieves the LayoutManager instance that created the given layoutChild.

Properties

childWidget

The widget that is associated to the LayoutChild instance.

constructLayoutChildChildWidget :: (IsLayoutChild o, MonadIO m, IsWidget a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “child-widget” property. This is rarely needed directly, but it is used by new.

getLayoutChildChildWidget :: (MonadIO m, IsLayoutChild o) => o -> m Widget

Get the value of the “child-widget” property. When overloading is enabled, this is equivalent to

get layoutChild #childWidget

layoutManager

The layout manager that created the LayoutChild instance.

constructLayoutChildLayoutManager :: (IsLayoutChild o, MonadIO m, IsLayoutManager a) => a -> m (GValueConstruct o)

Construct a GValueConstruct with valid value for the “layout-manager” property. This is rarely needed directly, but it is used by new.

getLayoutChildLayoutManager :: (MonadIO m, IsLayoutChild o) => o -> m LayoutManager

Get the value of the “layout-manager” property. When overloading is enabled, this is equivalent to

get layoutChild #layoutManager
