如何将列项添加到 QStandardItem

Question

我正在尝试将项目添加到行中，但 appendColum 正在提供

parent.appendColumn( sbl )
TypeError: 'PySide2.QtGui.QStandardItem.appendColumn' called with wrong argument types:
  PySide2.QtGui.QStandardItem.appendColumn(list)
Supported signatures:
  PySide2.QtGui.QStandardItem.appendColumn(typing.Sequence[PySide2.QtGui.QStandardItem])
11:16:05: /usr/bin/python3 exited with code 1

我不知道自己做错了什么。

QList 在 Python 中不存在，我已经尝试过其他的，比如 pythonlists、QListWidgets（作为示例），find/understand 什么 typing.Sequence[PySide2.QtGui.QStandardItem] 表示

在下面的示例代码中，当“testROWONLY”为False时，我得到了错误。，否则它只是在层次结构中添加行，这不是目标。

目标是将 JSONDICT 作为密钥 ID 的列添加到任何级别上..,

JSON 示例测试字符串的这一部分显示了一个 DICT：“Id”，带有一个数组。它们应该是该行上的列。，

{ "00000157438584" : [ { "Id" : [  4136 , "J" ] }, "NULL", "Uma Empresa Mestre MEI", 22181, { "dtInt" : [ 3 , 43908 ] }, "00000157438584" ] },

Answer 1

typing.Sequence[PySide2.QtGui.QStandardItem]) 表示 QStandardItems 的列表。

在上一个 else 中，您添加了一个简单的字符串，这显然不是正确的参数类型。
将其更改为：

    else:
        print("Item de Coluna" )
        sbl.append(QStandardItem(str(v)))
