将QLineEdit的属性添加到Qt中的QTable窗口小部件

Question

I want to add a Table Widget in my application. But some properties which I want are not supported for Table Widget , but are available for QLineEdit . For example Validator , PlaceHolderText , etc properties from QLineEdit . I want to have these properties for individual cells of Table Widget . I don't want to add QLineEdit in my GUI , only Table Widget . Is it possible to do this? Thank You.

Answer 1

Create a QStyledItemDelegate subclass that draws the text or placeholder text as normal (it can do this without reimplementing), but produces a QLineEdit as it's editor widget.

Add it using QTableWidget::setItemDelegate(QAbstractItemDelegate* delegate) .

Answer 2

我认为，您可以通过setCellWidget将这些单元格更改为QLineEdit ，并使用其功能：

the_table_widget->setCellWidget(row, col, new QLineEdit);
