gtkContainerGetFocusChain {RGtk2} | R Documentation |
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
.
gtkContainerGetFocusChain(object)
|
[GtkContainer ] a GtkContainer |
A list containing the following elements:
retval |
[logical] TRUE if the focus chain of the container
has been set explicitly. |
|
[list] 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. |
