python - QTreewidget only displays first letter of item name

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...

Answer 1

QTreeWidgetItem 构造函数需要一个字符串列表。尝试这个：

tw = self.ui.treeWidget
item = QtGui.QTreeWidgetItem(["TEST"])
tw.addTopLevelItem(item)

Answer 2

QtGui.QTreeWidgetItem 需要不同列的列表。您可以简单地将文本包装在列表中

item = QtGui.QTreeWidgetItem(["TEST"])

或者您可以为特定列设置文本。

item = QtGui.QTreeWidgetItem()
item.setText(0, "TEST")
