I'm using QListView, with a folder in excel with 2 columns one with questions and one with answers, I wanted to set the questions in the ListView widget, with the colors green and red, and when I type in the search box identify if the question is whether it is true or not.

Hi and welcome to devnet,
@rodrigoml said in set color(green/red) in conditions bool in listview:

This part is not really clear, can you maybe rephrase it ?

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

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

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. -
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.

returns error:
Exception has occurred: TypeError
QListWidget.setModel () is a private method -
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?
-
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:
import sys from PyQt5.QtWidgets import ( QApplication, QListWidgetItem, QListWidget, QLineEdit, QVBoxLayout, QWidget, QMainWindow, QListView, ) from PyQt5.QtCore import Qt, QSortFilterProxyModel from PyQt5.QtGui import QStandardItemModel, QStandardItem import pandas as pd class MainWindow(QWidget): 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() demo.show() sys.exit(app.exec_())

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.
