在QTableWidget中添加QCheckBox并使其居中显示(转)
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);
