Adding strings in QTreeWidget ?

[npc]

Hi All,

I am using QTreeWidget class to display the datas in tree.

Having list of qstrings which are stored in qstringlist, how can i move these strings to first column of qtreewidget ? and also i want to display those items with selection boxes which provide multiple selection.

thanks in advance,

What have you tried so far? Did you notice the example in the QTreeWidget docs?

1. Use QTreeWidget::setColumnCount() to set sufficient amount of columns
2. iterate the list of strings, create a QTreeWidgetItem per each
3. use QTreeWidgetItem::setFlags() to set the item checkable
4. use QTreeWidgetItem::setCheckState() to initialize the check state

and also QAbstractItemView::SelectionMode

Thanks JPN and aamer4yu,
Now I'm able to get the texts in tree widget.

actually each item should preceded by check box, for the user selection.
tried ItemIsUserCheckable and other flags in the setflag option, not working.

how to display each item with check box ?

Just follow the steps above.. Did you initialize the check state?

item->setFlags(item->flags() | Qt::ItemIsUserCheckable); // default flags + checkable
item->setCheckState(0, Qt::Unchecked); // you must also initialize the state

item->setFlags(item->flags() | Qt::ItemIsUserCheckable); // default flags + checkable
item->setCheckState(0, Qt::Unchecked); // you must also initialize the state

Could you tell how to get selected items into a list, from a treewidget ?.

Could you tell how to get selected items into a list, from a treewidget ?.

Come on! QTreeWidget::selectedItems()

[npc]

sorry, I forgot to tell that, I used that function... it always retuns the count of 1.
the list is in a multiple selection mode.

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

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

and I used the following code to get the item text.

QTreeWidgetItem it(selectedGrItems.at(0));
QString text = it.text(1);

QTreeWidgetItem it(selectedGrItems.at(0));
QString text = it.text(1);

To copy to clipboard, switch view to plain text mode 

but it is not getting the text

plz tell me how to get those items in a qstringlist ?

[jpn]

QTreeWidgetItem* it = selectedGrItems.at(0);
QString text = it->text(1);

QTreeWidgetItem* it = selectedGrItems.at(0);
QString text = it->text(1);

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 ();

How to get a whole list of selected items ?

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);
...
