gtkContainerGetFocusChain: 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

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. [ element-type GtkWidget][ out ][ transfer container ]
