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.

Methods
Overloaded methods
getChildWidget
layoutChildGetChildWidget Source #
:: (HasCallStack, MonadIO m, IsLayoutChild a) | |
=> a |
|
-> m Widget | Returns: a |
Retrieves the Widget
associated to the given layoutChild
.
getLayoutManager
layoutChildGetLayoutManager Source #
:: (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
