QTreeWidgetItem 内的 QComboBox [英] QComboBox inside QTreeWidgetItem

问题描述

有没有类似于(PyQT)的东西QTreeWidgetItem.setCheckState(0, Qt.Checked) 但是对于组合框?

我在参考中看不到任何内容，那么如何插入自定义 QComboBox 作为 QTreeWidgetItem 中的元素之一?

解决方案

使用

Is there something similar to the (PyQT) QTreeWidgetItem.setCheckState(0, Qt.Checked) but for the combo box?

I can't see anything in the reference, so how can I insert a custom QComboBox as one of the elements within QTreeWidgetItem?

解决方案

Use QTreeWidget::setItemWidget ( QTreeWidgetItem * item, int column, QWidget * widget ) to put the combo box into the cells.

For example, let's make all rows of the second column of a 2-column QTreeWidget to all be combo boxes:

QTreeWidgetItemIterator it(ui->treeWidget);
while (*it) {
    QComboBox *comboBox = new QComboBox(this);
    comboBox->addItems(QStringList() << "item1" << "item2");
    ui->treeWidget->setItemWidget(*it, 1, comboBox);
    ++it;
}

Our example widget now looks like this:
