I wanted to change the colors that were shown in the table, green (true), red (false).

like this

Do you want the text color to change only when filtering ?

@SGaist said in set color(green/red) in conditions bool in listview:

It could also be.
I wanted it to work like I did on listwidget:

however, listwidget does not work with models.
the text box (QlineEdite) is just a keyword search system.

[SGaist]

QListWidget has an internal model.

For your use case, you can already set the color of your entries when filling the model so no need to fiddle with it when doing your filtering.

when I use lista.setModel (filter_proxy_model)

returns error:
Exception has occurred: TypeError
QListWidget.setModel () is a private method

[SGaist]

As I wrote, QListWidget has an internal model. Using QListView with a QStandardItemModel and QSortFilterProxyModel is the correct way to implement what you want.

QSortFilterProxyModel

how do I do that?

[SGaist]

Do what ? Use QSortFilterProxyModel on top of a QStandardItemModel before a QListView ?

@rodrigoml Do you want something like the following? Your explanation is not very clear:

    QVBoxLayout,

    def __init__(self):
        super().__init__()

        self.setWindowTitle("Foxy Quizz")
        self.resize(480, 600)

        d = {"Perguntas": ["P1", "P2", "P3"], "Respostas": [True, False, True]}

        pf = pd.DataFrame(d)
        print(pf)

        model = QStandardItemModel(0, 1)
        view = QListView()

        filter_proxy_model = QSortFilterProxyModel()
        filter_proxy_model.setSourceModel(model)
        filter_proxy_model.setFilterCaseSensitivity(Qt.CaseInsensitive)
        filter_proxy_model.setFilterKeyColumn(0)

        view.setModel(filter_proxy_model)

        for question, status in zip(pf["Perguntas"], pf["Respostas"]):
            item = QStandardItem(question)
            item.setForeground(Qt.red if status else Qt.green)
            item.setEditable(False)
            model.appendRow(item)

        search_box = QLineEdit()
        search_box.textChanged.connect(filter_proxy_model.setFilterRegExp)
        mainLayout = QVBoxLayout(self)
        mainLayout.addWidget(search_box)
        mainLayout.addWidget(view)


if __name__ == "__main__":
    app = QApplication(sys.argv)

    demo = MainWindow()

That's right!! Thanks, I spent days studying, and I couldn't.

@rodrigoml The problem with your original code is the line: model.setItem(0, item) since you always set the items to the first row.
