在QTableWidget中添加QCheckBox并使其居中显示(转)

时间:2024-08-03 23:03:32

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

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