Adding strings in QTreeWidget ?

[jpn]

Hi,

When I tried to get all selected item in selectedGrItems, its always returns only single item, i.e; the gcount is 1 always.

QList<QTreeWidgetItem *> selectedGrItems = ui.GroupsTreeWidget->selectedItems();
int gcount = selectedGroupItems.count ();

QList<QTreeWidgetItem *> selectedGrItems = ui.GroupsTreeWidget->selectedItems();
int gcount = selectedGroupItems.count ();

To copy to clipboard, switch view to plain text mode 

How to get a whole list of selected items ?

Hi

A QTreeWidgetItem represents the whole row. Do you have several rows selected? Perhaps you want the text from different columns?

QString col1 = item->text(0);
QString col2 = item->text(1);
...

QString col1 = item->text(0);
QString col2 = item->text(1);
...

Hi

Yes, I have several rows selected. In my code the QTreeWidgetItem has the item which is selected last.

actually i used the following code to add the items into the the QTreeWidget

QList<QTreeWidgetItem *> groupItems;
 
for (int i = 0; i < gName.count(); ++i)
{	
	QTreeWidgetItem* n;
	n = new QTreeWidgetItem((QTreeWidget*)0, QStringList(gName.at(i)));
	n->setFlags( n->flags() | Qt::ItemIsUserCheckable );
	n->setCheckState(0,Qt::Unchecked);
        items.append(n);
}
 
int count = groupItems.count ();
 
ui.GroupsTreeWidget->insertTopLevelItems(0, groupItems);

QList<QTreeWidgetItem *> groupItems;

for (int i = 0; i < gName.count(); ++i)
{	
	QTreeWidgetItem* n;
	n = new QTreeWidgetItem((QTreeWidget*)0, QStringList(gName.at(i)));
	n->setFlags( n->flags() | Qt::ItemIsUserCheckable );
	n->setCheckState(0,Qt::Unchecked);
        items.append(n);
}

int count = groupItems.count ();

ui.GroupsTreeWidget->insertTopLevelItems(0, groupItems);

so i want to get the selected rows in a list

help me in this regard.

I see, the items are set as checkable. So just to make sure, are we talking about "checked" or "selected" items?

For checked items you can use QTreeWidgetItemIterator:

QTreeWidgetItemIterator it(treeWidget, QTreeWidgetItemIterator::Checked);
while (*it)
{
   QString col0 = (*it)->text(0);
   ...
 
   ++it;
}

QTreeWidgetItemIterator it(treeWidget, QTreeWidgetItemIterator::Checked);
while (*it)
{
   QString col0 = (*it)->text(0);
   ...

   ++it;
}

For selected items, try playing around with this:

#include <QtGui>
 
class TreeWidget : public QTreeWidget
{
	Q_OBJECT
 
public:
	TreeWidget(QWidget* parent = 0) : QTreeWidget(parent)
	{
		connect(this, SIGNAL(itemSelectionChanged()), this, SLOT(printSelection()));
	}
 
private slots:
	void printSelection()
	{
		qDebug() << "selection:";
		foreach (QTreeWidgetItem* item, selectedItems())
		{
			QStringList row;
			for (int col = 0; col < item->columnCount(); ++col)
			{
				row += item->text(col);
			}
			qDebug() << "row:" << row.join(", ");
		}
	}
};
 
int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
	TreeWidget treeWidget;
	treeWidget.setColumnCount(2);
	treeWidget.setSelectionMode(QAbstractItemView::ExtendedSelection);
	for (int i = 0; i < 10; ++i)
		new QTreeWidgetItem(&treeWidget, QStringList() << QString("item %1 col 0").arg(i) << QString("item %1 col 1").arg(i));
	treeWidget.show();
	return a.exec();
}
 
#include "main.moc"

#include <QtGui>

class TreeWidget : public QTreeWidget
{
	Q_OBJECT

public:
	TreeWidget(QWidget* parent = 0) : QTreeWidget(parent)
	{
		connect(this, SIGNAL(itemSelectionChanged()), this, SLOT(printSelection()));
	}

private slots:
	void printSelection()
	{
		qDebug() << "selection:";
		foreach (QTreeWidgetItem* item, selectedItems())
		{
			QStringList row;
			for (int col = 0; col < item->columnCount(); ++col)
			{
				row += item->text(col);
			}
			qDebug() << "row:" << row.join(", ");
		}
	}
};

int main(int argc, char *argv[])
{
	QApplication a(argc, argv);
	TreeWidget treeWidget;
	treeWidget.setColumnCount(2);
	treeWidget.setSelectionMode(QAbstractItemView::ExtendedSelection);
	for (int i = 0; i < 10; ++i)
		new QTreeWidgetItem(&treeWidget, QStringList() << QString("item %1 col 0").arg(i) << QString("item %1 col 1").arg(i));
	treeWidget.show();
	return a.exec();
}

oops I confused with checked items and selected items, got it right now.

I am doing with checked items.
