Wrapper Widget that manages focus for a whole dialog

this is a dialog with 2 rows. in the top row, there is the
|
||||
single (!) widget <textinput>. when the focus is in this
|
||||
group, left/right movement seems (!) to be doing nothing.
|
||||
|
||||
in the second row, there are two widgets and you can move
|
||||
left/right. also, you can go up from both to reach <textinput>,
|
||||
and from that go down and (depending on internat coordinates)
|
||||
reach either <okbutton> or <cancelbutton>.
|
||||
|
||||
but notice that this does _not_ do the layout for you,
|
||||
it rather defines an abstract layout.
