如何创建一系列键

Question

我需要根据按下状态传递多个键以启用Qt中的活动。最初我试图使用QKeySequence做同样的事情，但它似乎并不动态。

keyPressEvent() {
  if (keypress event) {
    switch(keyevent->key()) {
      Qt::Key_Alt:
        "add this key to qkeysequence"
      Qt::Key_Control:
         "add this key to qkeysequence"
      Qt::Key_Shift:
         "add this key to qkeysequence"
      Qt::Key_P:
         "add this key to qkeysequence"
    }
  }
  if (keyrelease event) {
     switch(keyevent->key()) {
      Qt::Key_Alt:
        "remove this key from qkeysequence"
      Qt::Key_Control:
         "remove this key from qkeysequence"
      Qt::Key_Shift:
         "remove this key from qkeysequence"
      Qt::Key_D:
         "remove this key from qkeysequence"
    }
  }

  handleKeySequence(qkeysequence);
}

handleKeySequence(qkeysequence) {
  if (qkeysequence matches Qt::Key_Ctrl) do something
  else if (qkeysequence matches Qt::Key_ctrl+Qt::Key_D) do something
  .... other such sequences
}

然而，QKeySequence似乎没有做任何事情，并尝试了更多的选择，他们也没有多少帮助。

任何帮助都会很棒，谢谢。
