**Event-Driven GUI: Creating a Virtual Wardrobe with PyQt6 and MVC Pattern** In this article, we will discuss how to create a virtual wardrobe application using PyQt6 and the Model-View-Controller (MVC) pattern. The virtual wardrobe will allow users to manage their clothing items and create outfits. ### Prerequisites - Python 3.9+ - PyQt6 - PySide6 (optional) ### Installation To install PyQt6 and required dependencies, use pip: ```bash pip install PyQt6 ``` ### Application Design Our virtual wardrobe application will consist of the following components: - **Model**: Represents the data structure of our clothing items and outfits. - **View**: Handles the GUI components, such as buttons and labels. - **Controller**: Acts as an intermediary between the model and view, managing the application's logic. ### Model (wardrobe.py) ```python from PyQt6.QtCore import QObject, pyqtSignal, pyqtSlot class WardrobeModel(QObject): def __init__(self): super().__init__() self.outfits = [] self.clothing_items = [] @pyqtSignal(str) def new_outfit(self, outfit): self.outfits.append(outfit) self.new_outfit.emit(outfit) @pyqtSignal(str) def new_clothing_item(self, item): self.clothing_items.append(item) self.new_clothing_item.emit(item) ``` ### View (wardrobe_view.py) ```python from PyQt6.QtWidgets import QApplication, QWidget, QVBoxLayout, QPushButton, QLabel, QLineEdit from wardroom import WardrobeModel class WardrobeView(QWidget): def __init__(self, model): super().__init__() self.model = model self.layout = QVBoxLayout() self.setLayout(self.layout) self.outfit_input = QLineEdit() self.layout.addWidget(self.outfit_input) self.outfit_button = QPushButton("Create Outfit") self.outfit_button.clicked.connect(self.create_outfit) self.layout.addWidget(self.outfit_button) self.clothing_item_input = QLineEdit() self.layout.addWidget(self.clothing_item_input) self.clothing_item_button = QPushButton("Add Clothing Item") self.clothing_item_button.clicked.connect(self.add_clothing_item) self.layout.addWidget(self.clothing_item_button) self.outfit_label = QLabel() self.layout.addWidget(self.outfit_label) self.clothing_item_label = QLabel() self.layout.addWidget(self.clothing_item_label) self.model.new_outfit.connect(self.update_outfit_label) self.model.new_clothing_item.connect(self.update_clothing_item_label) def create_outfit(self): outfit = self.outfit_input.text() self.model.new_outfit.emit(outfit) self.outfit_input.clear() def add_clothing_item(self): item = self.clothing_item_input.text() self.model.new_clothing_item.emit(item) self.clothing_item_input.clear() def update_outfit_label(self, outfit): self.outfit_label.setText(f"Outfit: {outfit}") def update_clothing_item_label(self, item): self.clothing_item_label.setText(f"Clothing Item: {item}") ``` ### Controller (wardrobe_controller.py) ```python from wardroom import WardrobeModel from wardrobe_view import WardrobeView class WardrobeController: def __init__(self): self.model = WardrobeModel() self.view = WardrobeView(self.model) def main(): import sys app = QApplication(sys.argv) controller = WardrobeController() controller.view.show() sys.exit(app.exec()) if __name__ == "__main__": main() ``` ### Conclusion In this article, we demonstrated how to create a virtual wardrobe application using PyQt6 and the Model-View-Controller (MVC) pattern. The application allows users to manage their clothing items and create outfits. **External Resources** - [PyQt6 Documentation](https://www.riverbankcomputing.com/software/pyqt/documentation) - [Qt Documentation](https://doc.qt.io/) **Please leave a comment below if you would like me to implement any additional features.**
