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

[cpp] view plaincopy
 
  1. QWidget *widget;  
  2. QHBoxLayout *hLayout;  
  3. QCheckBox *ckb;  
  4. ...  
  5. ckb = new QCheckBox();  
  6. hLayout = new QHBoxLayout();  
  7. widget = new QWidget(ui->tableWidget);  
  8. hLayout->addWidget(ckb);  
  9. hLayout->setMargin(0);                          // 必须添加, 否则CheckBox不能正常显示  
  10. hLayout->setAlignment(ckb, Qt::AlignCenter);  
  11. widget->setLayout(hLayout);  
  12. ...  
  13. ui->tableWidget->setCellWidget(row, column, widget);  

 

获取CheckBox的指针的方法

[cpp] view plaincopy
 
  1. QWidget *widget = (QWidget *)ui->tableWidget->cellWidget(row, column);  
  2. QCheckBox *ckb = (QCheckBox *)widget->children().at(1);  
  3. ckb->setChecked(true);  
  4. ...  

 

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("");        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);
