c++ - QTableWidget，居中cellWidgets

Question

有没有办法将 QCheckBox 作为 QTableWidget 的单元格小部件放置在单元格的中心，而不是左侧，而不需要额外的 QWidget 并将复选框添加到它的布局中？

Answer 1

使用setCellWidget 将QCheckBox 添加到表中:

QWidget *checkBoxWidget = new QWidget(); //create QWidget
QCheckBox *checkBox = new QCheckBox();   //create QCheckBox
QHBoxLayout *layoutCheckBox = new QHBoxLayout(checkBoxWidget); //create QHBoxLayout 
layoutCheckBox->addWidget(checkBox);     //add QCheckBox to layout
layoutCheckBox->setAlignment(Qt::AlignCenter); //set Alignment layout
layoutCheckBox->setContentsMargins(0,0,0,0);

ui->tableWidget->setCellWidget(0,0, checkBoxWidget);

也可以使用这些行来调整内容的大小:

ui->tableWidget->resizeRowsToContents();
ui->tableWidget->resizeColumnsToContents();

setCellWidget: Sets the given widget to be displayed in the cell in the given row and column, passing the ownership of the widget to the table.
