Question

从简单的字典中读取数据d = {key：['desc'，dateadded]} 目标是将数据添加到表视图中，并按列表中的日期排序。尝试将表放在主窗口时无法获取任何数据。

问题在于我如何将表放在主窗口上。我有一个工作小部件与表，我现在正在尝试合并这两个文件。目前应用程序崩溃。不要求你编写代码，但在正确的方向上推动将是一个很大的帮助。

Answer 1

在挖掘代码后，我找到了行

self.tableView = QtGui.QTableView(self.centralwidget)

需要是QTableWidget而不是View。这允许我设置值等等。

在tableview python中动态添加和排序项目
