Question

I am using this code but I cannot get current characters.

    function [] = edit2_keypressfcn(varargin)
        password = get(edit2,'userdata');
        key = get(fig,'currentkey');
        switch key
            case 'backspace'
                password = password(1:end-1); 
                SizePass = size(password); 
                if SizePass(2) > 0
                    asterisk(1,1:SizePass(2)) = '•';
                    set(edit2,'String',asterisk) 
                else
                    set(edit2,'String','')
                end
                set(edit2,'Userdata',password) 
            case 'escape'
            case 'insert'
            case 'delete'
            case 'home'
            case 'pageup'
            case 'pagedown'
            case 'end'
            case 'rightarrow'
            case 'downarrow'
            case 'leftarrow'
            case 'uparrow'
            case 'shift'
            case 'return'
                pus1_callback(varargin);
            case 'alt'
            case 'control'
            case 'windows'
            otherwise
                password = [password get(fig,'currentcharacter')];
                SizePass = size(password); 
                if SizePass(2) > 0
                    asterisk(1:SizePass(2)) = '*'; 
                    set(edit2,'string',asterisk) 
                else
                    set(edit2,'String','');
                end
                set(edit2,'Userdata',password) ;
        end
    end
