Python: PyQt Popup Window

Python: PyQt Popup Window

In PyQt, you can create a popup window (also known as a dialog or a modal window) using the QDialog class. A popup window is typically used to get user input, display messages, or perform other tasks that temporarily block the main application window. Here's a step-by-step guide to creating a simple PyQt popup window:

  • Import the necessary PyQt modules:
import sys from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QDialog, QVBoxLayout, QLabel
  • Create a subclass of QDialog to define your popup window:
class MyPopup(QDialog): def __init__(self): super().__init__() # Set window properties self.setWindowTitle("Popup Window") self.setGeometry(100, 100, 300, 150) # Create layout for the popup window layout = QVBoxLayout() # Add widgets to the layout label = QLabel("This is a popup window.") layout.addWidget(label) close_button = QPushButton("Close") close_button.clicked.connect(self.accept) layout.addWidget(close_button) # Set the layout for the popup window self.setLayout(layout)

In this code:

  • We create a subclass of QDialog named MyPopup.
  • Inside the MyPopup constructor, we set the window's title and dimensions.
  • We create a vertical layout (QVBoxLayout) to organize the widgets in the popup window.
  • We add a label and a close button to the layout.
  • The close button's clicked signal is connected to the accept method, which will close the popup when the button is clicked.
  • In your main application, create a button or event that triggers the popup:
class MyApp(QWidget): def __init__(self): super().__init__() self.setWindowTitle("Main Application") self.setGeometry(300, 300, 400, 200) button = QPushButton("Show Popup") button.clicked.connect(self.show_popup) layout = QVBoxLayout() layout.addWidget(button) self.setLayout(layout) def show_popup(self): popup = MyPopup() popup.exec_() if __name__ == "__main__": app = QApplication(sys.argv) window = MyApp() window.show() sys.exit(app.exec_())

In the main application:

  • We create a MyApp class that inherits from QWidget.
  • Inside the MyApp constructor, we create a button that, when clicked, calls the show_popup method.
  • The show_popup method creates an instance of the MyPopup class and calls exec_() to display the popup as a modal window.
  • Run the PyQt application by executing the script. When you click the "Show Popup" button, the popup window will appear.

This example demonstrates how to create a simple PyQt popup window with a label and a close button. You can customize the content and functionality of the popup window according to your needs.
