GI.Gtk.Objects.LayoutChild
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)

- layoutChildGetChildWidget :: (HasCallStack, MonadIO m, IsLayoutChild a) => a -> m Widget
- layoutChildGetLayoutManager :: (HasCallStack, MonadIO m, IsLayoutChild a) => a -> m LayoutManager
- constructLayoutChildChildWidget :: (IsLayoutChild o, MonadIO m, IsWidget a) => a -> m (GValueConstruct o)
- getLayoutChildChildWidget :: (MonadIO m, IsLayoutChild o) => o -> m Widget
- constructLayoutChildLayoutManager :: (IsLayoutChild o, MonadIO m, IsLayoutManager a) => a -> m (GValueConstruct o)

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.

Arguments
| :: (HasCallStack, MonadIO m, IsLayoutChild a) | |
| => a |
|
| -> m Widget | Returns: a |
Retrieves the Widget associated to the given layoutChild.
getLayoutManager
layoutChildGetLayoutManager Source #
Arguments
| :: (HasCallStack, MonadIO m, IsLayoutChild a) | |
| => a |
|
| -> m LayoutManager | Returns: a |
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) 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, MonadIO m, IsLayoutManager a) => a -> m (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
