How do I get Qlistview to include all the search details for pdf hits in QPdfSearchModel Class for python like it does in the documentation


When I do a pdf search using the QPdfsearchmodel class my model only seems to include the word I searched for and context before/context after:

enter image description here

However, in the documentation there is also a listing for the page no.:

From QPdfSearchModel Class documentation

I modified the Pyside6 port of the pdfwidgets/pdfviewer example from Qt v6.x by adding a text search bar to the top and replacing the bookmark view pane on the left with a Qlistview for the search results:

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

I have tried everything I can think of. I only modified mainwindow.py and ui_mainwindow.py below:

Solution

  • The documentation states that the information you need can be accessed via roles.
    You can inherit QIdentityProxyModel and build your desired text for the DisplayRole.

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