Description

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.

Synopsis

newtype LayoutChild = LayoutChild (ManagedPtr LayoutChild)
class (GObject o, IsDescendantOf LayoutChild o) => IsLayoutChild o
toLayoutChild :: (MonadIO m, IsLayoutChild o) => o -> m LayoutChild
noLayoutChild :: Maybe LayoutChild
layoutChildGetChildWidget :: (HasCallStack, MonadIO m, IsLayoutChild a) => a -> m Widget
layoutChildGetLayoutManager :: (HasCallStack, MonadIO m, IsLayoutChild a) => a -> m LayoutManager
constructLayoutChildChildWidget :: (IsLayoutChild o, IsWidget a) => a -> IO (GValueConstruct o)
getLayoutChildChildWidget :: (MonadIO m, IsLayoutChild o) => o -> m Widget
constructLayoutChildLayoutManager :: (IsLayoutChild o, IsLayoutManager a) => a -> IO (GValueConstruct o)
getLayoutChildLayoutManager :: (MonadIO m, IsLayoutChild o) => o -> m LayoutManager

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

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

noLayoutChild :: Maybe LayoutChild Source #

A convenience alias for Nothing :: Maybe LayoutChild.

Methods

Overloaded methods

getChildWidget

layoutChildGetChildWidget Source #

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 Source #

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, IsWidget a) => a -> IO (GValueConstruct o) Source #

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 Source #

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, IsLayoutManager a) => a -> IO (GValueConstruct o) Source #

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 Source #

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

get layoutChild #layoutManager
