Hello.
Question: how to find sub item, in a QTreeView
loaded QAbstractItemModel
model with model->match()
method?
Problem: model->match()
can't find sub items, wtf?!
Here is the example:
As you can see from the picture, I'm trying to expand Layouts
sub item with this code:
void Dialog::restoreState(void)
{
// get list
QSettings settings("settings.ini", QSettings::IniFormat);
settings.beginGroup("MainWindow");
QStringList List = settings.value("ExpandedItems").toStringList();
settings.endGroup();
foreach (QString item, List)
{
if (item.contains('|'))
item = item.split('|').last();
// search `item` text in model
QModelIndexList Items = model->match(model->index(0, 0), Qt::DisplayRole, QVariant::fromValue(item));
if (!Items.isEmpty())
{
// Information: with this code, expands ONLY first level in QTreeView
view->setExpanded(Items.first(), true);
}
}
}
Where settings.ini
file contains:
[MainWindow]
ExpandedItems=Using Containers, Connection Editing Mode, Form Editing Mode, Form Editing Mode|Layouts
PS: root items successfully expands on start!
