[問題] Qt: QPushButton 物件的回收該如何做
from: http://stackoverflow.com/questions/13521029/qt-memory-management
1: QPushButton *p_button = new QPushButton(this);
2: QPushButton my_button(this);
在 QWidget 產生 p_button, my_button,
p_button 沒問題, QWidget dtor 會負責 delete 它 (當然得先要記住它才行),
那 my_button 怎麼辦?
有辦法分辨某個指標的位址是 new 來的, 還是 stack 分配出來的嗎？
我印象中 qt 建議使用 new 來產生 object, 應該是這個關係,
但是我不確定。
