QTreeWidgetItem* currentItem returns memory address 0x0

[Axtroz]

Greetings, I'm trying to make a search form for my QTreeWidget.
My problem is that when the current selection changes it does a database operation to populate a tableview and it crashes.
After a bit of debugging I figured that the problem is that

// Item is a QString that 100% exists on the tree
    QTreeWidgetItem *selected = ui->tree->findItems(item,Qt::MatchExactly | Qt::MatchRecursive | Qt::MatchWrap)[0];
    selected->setSelected(true); // This selects the node on the tree successfully (visually)
    qDebug() << ui->tree->currentItem(); // However this returns 0x0 until I click on the already selected item, then it returns the mem address correctly.

// Item is a QString that 100% exists on the tree
    QTreeWidgetItem *selected = ui->tree->findItems(item,Qt::MatchExactly | Qt::MatchRecursive | Qt::MatchWrap)[0];
    selected->setSelected(true); // This selects the node on the tree successfully (visually)
    qDebug() << ui->tree->currentItem(); // However this returns 0x0 until I click on the already selected item, then it returns the mem address correctly.

To copy to clipboard, switch view to plain text mode 

I'm a bit confused why is it happening? The tree emits the signal that the current item changes, but when I attempt to retrieve the new current item it returns an invalid pointer.
Thanks in advance for all replies.

The selection and the current item are two different things. Until you set a current item using the mouse, keyboard, or code there is no current item.

Line 2 will crash if there is no match.
