如何让 Qlistview 在 python 的 QPdfSearchModel 类中包含 pdf 点击的所有搜索详细信息，就像在文档中一样

Question

当我使用 QPdfsearchmodel 类进行 pdf 搜索时，我的模型似乎只包含我搜索的单词以及之前/之后的上下文：

但是，在文档中还列出了页码：

我修改了 Qt v6.x 中 pdfwidgets/pdfviewer 示例的 Pyside6 端口，在顶部添加了一个文本搜索栏，并将左侧的书签视图窗格替换为用于搜索结果的 Qlistview：

https://doc.qt.io/qtforpython-6/examples/example_pdfwidgets_pdfviewer.html

我已经尝试了我能想到的一切。我只修改了下面的mainwindow.py和ui_mainwindow.py：

文档指出您需要的信息可以通过角色访问。
你可以像这样继承QidentityProxyModel

class MyProxy(QIdentityProxyModel):
    
    def data(index, role):
        if role == Qt.ItemDataRole.DisplayRole:
            return f'Page {self.sourceModel().data(index, QPdfSearchModel.Role.Page): {super().data(index, role)}'
