信号和槽

[haoyunlailai]

Kf.h:

class CKf : public QThread
{
Q_OBJECT
public:
explicit CKf();
protected:

signals:
void OnLineEvent(int val);

};


class COKf :public CKf
{
Q_OBJECT
public:
explicit COKf();

protected:

signals:

protected slots:
};


MainWindow.h:

class MainWindow : public QMainWindow
{
Q_OBJECT

public:
explicit MainWindow(QWidget *parent = 0);

~MainWindow();

private:
Ui::MainWindow *ui;
COKf FKf;

public slots:
void OnLineEvent(int val);
};


MainWindow.cpp:

想把类中OnIOEvent信号关联到MainWindow的槽怎么实现，这样好像不对connect(FKf,SIGNAL(onLineEvent(bool)), this, SLOT(onLineEvent(bool)));

[RabinSong]

跨线程的关联用队列的处理方式看看

[写不动代码的人]

如果不需要操作共享数据，这样可以用

[Trump_zhai]

connect(FKf,SIGNAL(onLineEvent(int)), this, SLOT(onLineEvent(int)));
