gtkContainerGetFocusChain {RGtk2} | R Documentation

## 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.
