qt信号和槽

类定义时：

class A {

Q_SIGNALS:
void syncinitApp(NQIntent *pIntent );

private Q_SLOTS:
void onSyncinitApp(NQIntent *pIntent );

}

可在构造函数中进行：connect(this, SIGNAL(syncinitApp(NQIntent *)), this, SLOT(onSyncinitApp(NQIntent *)));

可在析构函数中进行：disconnect(this, SIGNAL(syncinitApp(NQIntent *)), this, SLOT(onSyncinitApp(NQIntent *)));

可在需要跳转处：emit syncinitApp(pNQIntent);
