QTableWidget中添加按钮

添加按钮

void QTableWidget::setCellWidget ( int row, int column, QWidget * widget )

widget可以是自己定义的按钮

class MyPushButton : public QPushButton{    Q_OBJECTpublic:    explicit MyPushButton(int i, int j, int flag);    ~MyPushButton();    void mySetText();//i对应端口信息}
mySetText()函数中:

setStyleSheet("background-color: rgb(255, 100, 0);");//橙色setToolTip(tr("端口未授权"));//配置的MAC地址和采集卡不符合setText(tr("端口%1").arg(m_no + 1));

按钮添加完之后怎么去触发它的点击信号呢?尝试了很多中方法,比如直接调用  QTableWidget的itemclicked函数,都失败了,

最后从Stackoverflow上找到了类似的方法,将comboBox的触发方法改成pushButton就好了

QSignalMapper* signalMapper = new QSignalMapper(this);connect(newBtn, SIGNAL(clicked()), signalMapper, SLOT(map()));//存储按钮signalMapper->setMapping(newBtn, QString("%1-%2").arg(rowCount).arg(i + 2));connect(signalMapper, SIGNAL(mapped(const QString &)),this, SLOT(changed(const QString &)));//槽函数void MainWindow::changed(QString position){    QStringList coordinates = position.split("-");    int row = coordinates[0].toInt();    int col = coordinates[1].toInt();    disPlayPort(row,col);//row 和col就是对应的行和列,对应到相应的按钮}
