matlab中gui设计时如何隐藏密码,使密码显示为星号

Answer 1

设置该控件的KeypressFcn属性，通过链接的回调函数，使得每输入一个字符后马上用*号代替。

下面是一段回调函数的代码，可以参照一下

function PasswordKeyPress(hObject,event)

hAuth = getappdata(0,'hAuth');

password = get(hAuth.ePassword,'UserData');

switch event.Key

   case 'backspace'

      password = password(1:end-1);

   case 'return'

      uiresume;

      return;

   otherwise

      password = [password event.Character];

end

set(hAuth.ePassword,'UserData',password)

Answer 2

function PasswordKeyPress(hObject,event)

hAuth = getappdata(0,'hAuth');

password = get(hAuth.ePassword,'UserData');

switch event.Key

case 'backspace'

password = password(1:end-1);

case 'return'

uiresume;

return;

otherwise

password = [password event.Character];

end

set(hAuth.ePassword,'UserData',password)
