如何創建一系列的按鍵

Question

我需要傳遞多個按鍵的基礎上按下的狀態，以啓用Qt中的活動。最初我試圖使用QKeySequence來做同樣的事情，但它似乎並不是動態的。

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似乎沒有做任何事情在那裏，嘗試了一些更多的選擇，並且他們不幫助不大無論是。

任何幫助將是偉大的，謝謝。
