我有一个 QTreeview,我使用了这个样式表

QTreeView#treeView::item:selected:active
{
    background: qlineargradient(x1: 0, y1: 0, x2: 0, y2: 1, stop: 0 #6ea1f1, stop: 1 #567dbc);
}
QTreeView#treeView::item:hover
{
    background: qlineargradient(x1:0, y1:0, x2:0, y2:1, stop:0 #e7effd, stop:1 #cbdaf1);
    border: 1px solid #bfcde4;
}
QTreeView#treeView::item:has-children
{
    background: qlineargradient(x1:0, y1:0, x2:0, y2:1, stop:0 #cccccc, stop:1 #aaaaaa);
    border: 1px solid #777777;
    border-left: 0;
    border-right: 0;
    font-weight: bold;
}

它工作正常。但是我用

self.treeView.setItemDelegate(GenericDelegate())

其中 GenericDelegate 定义如下

class GenericDelegate(QItemDelegate):

    def _init_(self, parent=None):
        super(GenericDelegate, self)._init_(parent)

    def createEditor(self, parent, option, index): 
        if index.row()==1:
            cb = QtGui.QComboBox(parent)
            cb.addItems('A')
            cb.addItems('B')
            return cb

我的风格已经不行了!
我做错了什么?

我应该使用

QStyledItemDelegate

代替

QItemDelegate 

现在可以了!
