[Octave-bug-tracker] [bug #54942] implement uicontrol focusing behavior

[Pantxo Diribarne]

Follow-up Comment #4, bug #54942 (project octave):

@Rik:
>> What is this piece of code?
This was indeed debugging leftover, thaks, I pushed the patch here:

http://hg.savannah.gnu.org/hgweb/octave/rev/80c8062e855a

>> I thought that if the button had the focus and I typed <RETURN> that the
button would be activated

No, this just gives this uicontrol (widget) the keyboard focus. As a result it
is this widget that will receive keyboard events and have a chance to handle
them.
Now if you want the uicontrol to react on <return> entry you need to provide a
corresponding "keypressfcn", e.g.


function keypress (h, ev)
  if (strcmp (ev.Key, "return"))
    close (gcbf ())
  endif
endfunction

uicontrol ("keypressfcn", @keypress);
