How to allow the insite renaming of a QTreeWidgetItem

j.lastra

Hello:
I have filled a QTreeView by code, inserting a collection of QTreeWidgetItem. I am inserting by code new items in the TReeView, and I need to create them in 'edition mode' to allow the user the renaming of the new node,
such as is made by the 'new folder' command in Windows.

I don´t how to do it, is it possible ? nad how to do it ?

Regards,
Juan

Hi and welcome to devnet,

You can simply call the edit function from QTreeWidget

Chris Kawa

Don't mix QTreeView and QTreeWidgetItems. The latter should be used with QTreeWidget, not QTreeView.

That being said, when you create a QTreeWidgetItem remember to "setFlags":http://qt-project.org/doc/qt-5/qtreewidgetitem.html#setFlags to contain Qt::ItemIsEditable (apart from the default ones) and then call "editItem":http://qt-project.org/doc/qt-5/qtreewidget.html#editItem

Thank you to Chris and Sgaist, but it doesn´t work. I show you my code below.
After the editItem() call, the item's box doesn´t open.
Moreover, whenever I make double-clicl on any item, the item doesn´t
change to editing, such as any standard tree view in Windows.

 // We get the root node to insert a new palette

 usersPaletteRoot = ui.m_TreePalView->topLevelItem(1);

 // We create the novel palette entry

 newChild = new QTreeWidgetItem();

 newChild->setText(0, "New palette");

 newChild->setFlags(newChild->flags() | 
  Qt::ItemIsEditable | Qt::ItemIsEnabled
  | Qt::ItemIsSelectable);

 // We insert a new row in blank in the palette's list 

 usersPaletteRoot->addChild(newChild);

 disconnect(ui.m_TreePalView, SIGNAL(itemClicked(QTreeWidgetItem*, int)),
  this, SLOT(OnPaletteSelected(QTreeWidgetItem*, int)));

 newChild->setSelected(true);

 ui.m_TreePalView->editItem(newChild, 0);

Just checked this:

auto item = new QTreeWidgetItem(ui->treeWidget, QStringList {"Foo"});
item->setFlags(item->flags() | Qt::ItemIsEditable);
ui->treeWidget->editItem(item);

Works as expected. Your code is similar so there's got to be some problem elsewhere.

usersPaletteRoot = ui.m_TreePalView->topLevelItem(1);

Is there always an element with index 1?
