Hello!

I have a simple GUIDE GUI that has four edit boxes to gather information, and a "Done" button at the bottom. I use uicontrol(handles.editbox1) to put the cursor at the top editbox, and the user can Tab down through the boxes and then to the Done button. At that point, the user can exit by clicking on the Done button, but it would be much cleaner to have them just press "Enter".

Is this properly done in the KeyPressFcn callback for handles.done_button? And do you just see if getkey == 13 in eventdata? I am not sure where this is documented!

Thanks!

Yes, keypressfcn is suitable for this. The eventdata will have a structure for which the field Key will contain 'return' in this case.

在 MATLAB Online 中打开

Example:

but = uicontrol('style','push', 'String', 'Type here', 'keypressfcn', @(hObject, eventdata) disp(eventdata.Key))

In your situation, I would suggest:

function done_Callback(hObject, eventdata, handles)
   finish_up(hObject, eventdata, handles);
function done_KeyPressFcn(hObject, eventdata, handles)
  if strcmp(eventdata.Key, 'return')
   finish_up(hObject, eventdata, handles);
  end
