How to add a QCompleter to a Qtreeview

[electric-dev]

Hello, good evening. I have a small application that is used to add tasks to be done, and for this I use a QTreeview. Now I want to add word autocompletion using the QCompleter class, but I haven’t been able to do so. Could you please help me?
Below is some of the code I have written so far.

class Por_Hacer(QTreeView):
    def __init__(self):
        super().__init__()
        self.setStyleSheet("background-color:#FF313131;color:white;font:bold 16px;border:None;")

        

        completar=["ABB","auto","avellana","asturia"]  
        
        completer = QCompleter(completar)
        completer.setCaseSensitivity(Qt.CaseInsensitive)
        completer.setModel(QFileSystemModel(completer))
       
        self.header().hide()
        self.setAnimated(True)

        self.my_model=QStandardItemModel(self,completer)

        self.setModel(self.my_model)

@electric-dev said in How to add a QCompleter to a Qtreeview:

    completar=["ABB","auto","avellana","asturia"]  
    completer = QCompleter(completar)
    ...
    completer.setModel(QFileSystemModel(completer))
    ...
    self.my_model=QStandardItemModel(self,completer)
    self.setModel(self.my_model)

These three sections of code are mutually incompatible. QCompleter supports a single model at a time.

In addition, the completer needs to be set on an input widget such as QLineEdit, or queried as described in the documentation.
