Gets the child widget of self.

new

windowHandleNew

Arguments

:: (HasCallStack, MonadIO m)

=> m WindowHandle

Returns: a new WindowHandle.

Creates a new WindowHandle.

Properties

child

No description available in the introspection data.

clearWindowHandleChild :: (MonadIO m, IsWindowHandle o) => o -> m ()

Set the value of the “child” property to Nothing. When overloading is enabled, this is equivalent to

clear #child

constructWindowHandleChild :: (IsWindowHandle o, MonadIO m, IsWidget a) => a -> m (GValueConstruct o)

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

getWindowHandleChild :: (MonadIO m, IsWindowHandle o) => o -> m (Maybe Widget)

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

get windowHandle #child

setWindowHandleChild :: (MonadIO m, IsWindowHandle o, IsWidget a) => o -> a -> m ()

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

set windowHandle [ #child := value ]
