🏗️ Architecture & Design

Python Conventions Followed

✓ PEP 8 style guide
✓ Type hints throughout
✓ Comprehensive docstrings
✓ Signal/slot pattern
✓ Worker threading for async
✓ Exception handling
✓ Logging integration

HydroSwift Integration

✓ Uses core hydroswift.* APIs
✓ Respects dataset naming conventions
✓ Follows basin naming from WRIS
✓ Mirrors CLI functionality
✓ Maintains consistent output structure

Code Organization

✓ Modular component design
✓ Clear separation of concerns
✓ Reusable panel classes
✓ Signal-based communication
✓ Thread-safe operations

📖 Usage Examples

Example 1: Basic Workflow

# Launch GUI
from swift_app.gui.app import main
main()

Then in the GUI:

Select basin: "Godavari"
Select variable: "discharge"
Click "Discover Stations"
Go to "Configuration" tab
Set date range: 2023-01-01 to 2024-01-01
Click "Download Selected Stations"
Monitor progress in log
View results in "Results" tab
Click "Plot Selected Data" to visualize

Example 2: Programmatic Extension

from PyQt5.QtWidgets import QApplication
from swift_app.gui.main_window import HydroSwiftGUI
import sys

app = QApplication(sys.argv)
gui = HydroSwiftGUI()
gui.show()

# Access components programmatically
stations = gui.wris_panel.discovered_stations
config = gui.config_panel.get_config()

sys.exit(app.exec_())

Example 3: Custom Panel Addition

# In main_window.py _setup_ui method:

from some_module import MyCustomPanel

self.custom_panel = MyCustomPanel()
self.tab_widget.addTab(self.custom_panel, "🔧 Custom")
self.custom_panel.log_message.connect(self.logger_widget.append_log)

🔧 Customization Guide

Change Default Output Directory

Edit main_window.py:

self.output_dir = Path(os.path.expanduser("~/hydroswift_data"))

Add New Basin

Basins are loaded from API, but hardcoded fallback in panels.py:

# In WRISDiscoveryPanel._populate_basins()
self.basin_combo.addItems(["Godavari", "Krishna", "NewBasin"])

Customize Color Scheme

Edit logger_widget.py:

LOG_COLORS = {
    "info": QColor(0, 100, 255),      # Custom blue
    "success": QColor(0, 200, 0),     # Custom green
    "error": QColor(255, 0, 0),       # Custom red
}

Add Menu Items

Edit main_window.py._setup_menu_bar():

custom_menu = menubar.addMenu("&Custom")
custom_action = QAction("Custom Option", self)
custom_action.triggered.connect(self._custom_handler)
custom_menu.addAction(custom_action)

    status_changed = pyqtSignal(str)
    log_message = pyqtSignal(str, str)
    
    def __init__(self):
        super().__init__()
        self._setup_ui()

Register in Main Window

self.my_panel = MyPanel()
self.tab_widget.addTab(self.my_panel, "📋 Label")
self.my_panel.log_message.connect(self.logger_widget.append_log)

Implement Async Operations

worker = WorkerThread(self._worker_func)
worker.result_ready.connect(self._on_complete)
worker.start()
