Qt Embedded for Linux。键盘布局切换很多次

Question

我试试：

if(lang_toggle==0)
{
      server->closeKeyboard();
      currentKeyboardHandler =
             QKbdDriverFactory::create("TTY", "keymap=/root/ar.qmap");
      server->setKeyboardHandler(currentKeyboardHandler);
      lang_toggle = 1 ;
}
else if(lang_toggle==1)
{
      server->closeKeyboard();
      currentKeyboardHandler =
            QKbdDriverFactory::create("TTY", "keymap=/root/en.qmap");
      server->setKeyboardHandler(currentKeyboardHandler);
      lang_toggle = 0 ;
}

如上所述here

它对我有用，但经过一些toggel制作分段错误
