问题描述

有没有办法将QModelIndex转换为QString?这个的主要目标是我想使用动态生成的QListView项目的内容。

  QFileSystemModel * foolist = new QFileSystemModel; 
foolist-> setRootPath(QDir :: rootPath());
foolistView-> setModel(foolist);

[...]

QMessageBox bar;
QString foolist_selectedtext = foolistView-> selectionModel() - > selectedIndexes();
bar.setText(foolist_selectedtext);
bar.exec;这是甚至是正确的方式来获得当前选择的项目吗?


提前感谢!

解决方案
  foolistView-> selectionModel () - > selectedIndexes(); 

发送QModelIndex的QList(只有一个,如果你查看是在QAbstractItemView :: SingleSelection) / p>

QModelIndex方法返回一个对应于此索引值的QVariant。



您可以通过调用。


Is there a way to convert QModelIndex to QString? The main goal behind this is that I want to work with the contents of dynamically generated QListView-Items.

QFileSystemModel *foolist = new QFileSystemModel;
    foolist->setRootPath(QDir::rootPath());
    foolistView->setModel(foolist);

[...]

QMessageBox bar;
QString foolist_selectedtext = foolistView->selectionModel()->selectedIndexes();
bar.setText(foolist_selectedtext);
bar.exec;

Is this even the correct way to get the currently selected Item?

Thanks in advance!

解决方案
foolistView->selectionModel()->selectedIndexes();

Send you back a QList of QModelIndex (only one if you view is in QAbstractItemView::SingleSelection)

The data method of QModelIndex return a QVariant corresponding to the value of this index.

You can get the string value of this QVariant by calling toString on it.
