QTreeWidgetItem constructor expects a list of strings. Try this:
tw = self.ui.treeWidget
item = QtGui.QTreeWidgetItem(["TEST"])
tw.addTopLevelItem(item)
Question
Im learning how to use QTreeWidget and Im stuck adding new items to it. The QTreewidget itself is created with qtdesigner, so my idea was just to add items. eg:
tw = self.ui.treeWidget
item = QtGui.QTreeWidgetItem("TEST")
tw.addTopLevelItem(item)
But in the treewidget only appears the first letter of "TEST". Doesnt matter what I type, it always only displays the first letter and I have no idea why...

The QtGui.QTreeWidgetItem is expecting a list for different columns. You can simply wrap your text in a list
item = QtGui.QTreeWidgetItem(["TEST"])
or you can set the text for a specific column.
item = QtGui.QTreeWidgetItem()
item.setText(0, "TEST")
