gtkContainerGetFocusChain

Description

Retrieves the focus chain of the container, if one has been set explicitly. If no focus chain has been explicitly set, GTK+ computes the focus chain based on the positions of the children. In that case, GTK+ stores NULL in focusable.widgets and returns FALSE.

Usage

gtkContainerGetFocusChain(object)

Arguments

object

a GtkContainer

Value

A list containing the following elements:

`retval`	[logical] `TRUE` if the focus chain of the container has been set explicitly.
`focusable.widgets`	location to store the focus chain of the container, or `NULL`. You should free this list using `gListFree()` when you are done with it, however no additional reference count is added to the individual widgets in the focus chain.
