「uintisWidget:1;」のコロン(:)演算子の意味は何ですか。Qtで?「uintisWidget:1;」です 「uintisWidget(1)」と同等ですか?
Qtのコードは
QObjectData
{
public:
virtual ~QObjectData() = 0;
QObject *q_ptr;
QObject *parent;
QObjectList children;
uint isWidget : 1;
uint pendTimer : 1;
uint blockSig : 1;
uint wasDeleted : 1;
uint ownObjectName : 1;
uint sendChildEvents : 1;
uint receiveChildEvents : 1;
uint inEventHandler : 1;
uint inThreadChangeEvent : 1;
uint hasGuards : 1; //true iff there is one or more QPointer attached to this object
uint unused : 22;
int postedEvents;
QMetaObject *metaObject; // assert dynamic
};
