Hi,

I wonder why everything runs well just the enter key. Part of my code as below:

function figure1_WindowKeyReleaseFcn(hObject, eventdata, handles)

switch eventdata.Key

    case 'a'
        set(handles.edit1,'String','A');
    case 'b'
        set(handles.edit1,'String','B');
    case 'c'
        set(handles.edit1,'String','C');
    case 'd'
        set(handles.edit1,'String','D');
    case 'delete'
        set(handles.edit1,'String','');
    case 'backspace'
        set(handles.edit1,'String','');
    case 'enter'
        set(handles.edit1,'String','');

The edit1 text box can display A, B, C, D every time I press the corresponding key on keyboard. It can display empty box when i press backspace or delete. But it cannot for the enter key. Nothing happen when I press enter. Why???

Thank you very much.
