Hi,
if I have a listwidget, is it possible to detect if no item of the listwidget was selected?
I searched the web, but found nothing helpful...
amount_of_selected_items = self.listbox_profile.selectedItems().count()
if amount_of_selected_items == 0:
QMessageBox("text")thanks...
try
amount_of_selected_items = len(self.listbox_profile.selectedItems())
Do you need to know the number? You don't if you are only checking if there are selected items. You can do this instead.
if not self.listbox_profile.selectedItems():
QMessageBox("text")
Hi,
Axel_Erfurt and deanhystad...
Thanks a lot for your answers!!
The solution from Axel_Erfurt works good.
I don't know what I'm doing wrong, but the solution from deanhystad doesn't work in my code...
Never mind...
I wish you a pleasant day!!
Greetings...
deanhystad's solution also works.
import sys
from PyQt6.QtWidgets import (QApplication, QMainWindow, QGridLayout, QListWidget)
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.setWindowTitle('Test')
self.setGeometry(100, 100, 400, 100)
self.list_widget = QListWidget()
self.list_widget.addItems(['Hello', 'World'])
self.setCentralWidget(self.list_widget)
self.check_selected()
self.list_widget.setCurrentRow(1)
self.check_selected()
self.show()
def check_selected(self):
if not self.list_widget.selectedItems():
print("nothing selected")
else:
print(f"row {self.list_widget.currentRow()} selected")
if __name__ == '__main__':
app = QApplication(sys.argv)
window = MainWindow()
sys.exit(app.exec())Output:
nothing selected
row 1 selected
