QTreeviewの列をPysideで編集可能にする

Question

QTreeViewの2番目の列を編集可能にするにはどうしたらいいですか？

Answer 1

あなたは使用しないでください。

{Your QTreeView}.setEditTriggers(QtGui.QAbstractItemView.NoEditTriggers)

あなたが任意の項目を編集することはできませんので、。

編集可能なプロパティ要素を要素、つまり{your QStandardItem}.setEditable({your value})に配置する必要があります。あなたのケースでは

追加：

model.item(0, 0).setEditable(False) 
model.item(0, 1).setEditable(True) 
model.item(0, 2).setEditable(False) 
model.item(0, 3).setEditable(False) 

後

... 
model.setData(model.index(0, 0), x, role=QtCore.Qt.UserRole) 
model.setData(model.index(0, 0), x.buffer_id) 
model.setData(model.index(0, 1), x.name) 
model.setData(model.index(0, 2), len(x.nodes)) 
model.setData(model.index(0, 3), x.color, QtCore.Qt.BackgroundRole) 
.... 

の完全なコード：

     self.nodes = nodes if nodes is not None else [] 
     self.color = QtGui.QBrush(QtGui.QColor(0, 0, 0, 255)) 

     self.randomize_color() 

    def randomize_color(self): 
     r = random.randrange(0, 255) 
     g = random.randrange(0, 255) 
     b = random.randrange(0, 255) 

     self.color = QtGui.QBrush(QtGui.QColor(r, g, b, 255))
