Get selected items from QListWidget in PyQt QGIS using GIS software (2 Options!!)

In this tutorial, we will discuss two different ways to return a list of selected items from a QListWidget in PyQt with QGIS using the Python programming language.

Method 1: Using a Loop

Step 1: Import the necessary modules

from qgis.PyQt.QtWidgets import QListWidget, QApplication, QListWidgetItem

Step 2: Create a QListWidget

list_widget = QListWidget()

Step 3: Populate the QListWidget with items

list_widget.addItem(QListWidgetItem("Item 1"))
list_widget.addItem(QListWidgetItem("Item 2"))
list_widget.addItem(QListWidgetItem("Item 3"))

Step 4: Get the list of selected items

selected_items = []
for item in list_widget.selectedItems():
    selected_items.append(item.text())
print(selected_items)

Method 2: Using list comprehensions

Step 1: Import the necessary modules

from qgis.PyQt.QtWidgets import QListWidget, QApplication, QListWidgetItem

Step 2: Create a QListWidget

list_widget = QListWidget()

Step 3: Populate the QListWidget with items

list_widget.addItem(QListWidgetItem("Item 1"))
list_widget.addItem(QListWidgetItem("Item 2"))
list_widget.addItem(QListWidgetItem("Item 3"))

Step 4: Get the list of selected items using list comprehensions

selected_items = [item.text() for item in list_widget.selectedItems()]
print(selected_items)

These two methods both achieve the same result – they return a list of selected items from a QListWidget in PyQt with QGIS. You can choose whichever method you find more readable and easy to use in your application.

I hope this tutorial helps you understand how to return a list of selected items from a QListWidget in PyQt with QGIS. Let me know if you have any questions or need further clarification.
