I'm not sure about focus, if by that you mean keyboard focus -
generally the control over which toplevel has the keyboard focus
is left up to the window manager. (People might become upset if 
it changed in unexpected manners.) But one nice thing you can do
in this regard is to raise the window when the item is selected
again. (I think this should be done to all of the GIMP's dialogs.)

An example of doing this follows. (gtk_input_dialog is a widget
for controlling XInput devices.)
