实现思路:把QCheckBox嵌入式到一个水平布局中
QWidget *widget;
QHBoxLayout *hLayout;
QCheckBox *ckb;
...
ckb = new QCheckBox();
hLayout = new QHBoxLayout();
widget = new QWidget(ui->tableWidget);
hLayout->addWidget(ckb);
hLayout->setMargin(0); // 必须添加, 否则CheckBox不能正常显示
hLayout->setAlignment(ckb, Qt::AlignCenter);
widget->setLayout(hLayout);
...
ui->tableWidget->setCellWidget(row, column, widget);
获取CheckBox的指针的方法
QWidget *widget = (QWidget *)ui->tableWidget->cellWidget(row, column);
QCheckBox *ckb = (QCheckBox *)widget->children().at(1);
ckb->setChecked(true);
...
备注: 可使用 qDebug() << widget->children(); 输出widget的child列表 从而判断CheckBox的index

//开关按钮
QWidget* widget = new QWidget();
QToolButton* switchBtn = new QToolButton(widget);
switchBtn->setFixedSize(QSize(nWidth, nHeight));
switchBtn->setText("关");
switchBtn->setStyleSheet(offStyle);
QHBoxLayout* hLayout = new QHBoxLayout(widget);
hLayout->setMargin(0);
hLayout->addWidget(switchBtn);
hLayout->setAlignment(switchBtn, Qt::AlignCenter);
devTableWidget->setCellWidget(row, column, widget);
connect(switchBtn, SIGNAL(clicked()), switchMapper, SLOT(slot_switchBtn()));
//获取按钮指针 QToolButton*toolBtn=(QToolButton*)devTableWidget->cellWidget(row,column)->children().at(0);
