QTreeWidgetItems search issue

Cobra91151

Hi! I want to search items in QTreeWidget. The problem is, it doesn't hide the items that don't match the string.

QString data = "Some text";
QList<QTreeWidgetItem*> itemsList = treeWidget->findItems(data, Qt::MatchContains | Qt::MatchRecursive, 0);
    for (QTreeWidgetItem *item : itemsList)
    {
        if (!data.isEmpty()) {
            if (item->text(0) == data) {
                item->setHidden(false);
            } else {
                item->setHidden(true);
            }
        } else {
            item->setHidden(false);
        }
    }

I want to hide items when they are not matching, and display the matching one. Thanks.

Hi,

You are only looping on items that do match your search so the others will stay untouched.

Thank you. I have fixed the issue. I post code here, so people can find a solution.

Code:

for (int i = 0; i < treeWidget->topLevelItemCount(); i++) {
        QTreeWidgetItem *item = treeWidget->topLevelItem(i);
        QList<QTreeWidgetItem*> itemsList = treeWidget->findItems(data, Qt::MatchContains | Qt::MatchRecursive, 0);
        for (QTreeWidgetItem *searchedItem : itemsList)
        {
            if (!data.isEmpty()) {
                searchedItem->setHidden(false);
                item->setHidden(true);
            } else {
                item->setHidden(false);
            }
        }
    }
