Qt事件

class QtLearn : public QMainWindow
{
Q_OBJECT


public:
QtLearn(QWidget *parent = 0);
~QtLearn();
private:
Ui::QtLearnClass ui;
//信号槽
private slots:
void handleButton();

};

Qt信号槽要好使必须使用

private slots:来定义函数。

然后用

QObject::connect(ui.pushButton, SIGNAL(clicked()), this, SLOT(handleButton()));

来连接。
