Resolves: #504

Problem

Font styles (bold/italic) were not persisting after:

• Reloading the application
• Moving labels to new buttons
• Using the reset functionality

Root Cause

The issue was caused by missing font_weight and style parameters when loading KeyLabel objects from JSON data. When labels were loaded from the page configuration, these font styling attributes were not being properly restored, causing them to revert to default values.

Solution

Added the missing font styling parameters to all KeyLabel creation points:

1. Fixed clear_values() method in KeyLabel.py:

   • Added self.style = None to properly clear the font style when resetting

2. Fixed load_from_input_dict() for keys in DeckController.py:

   • Added font_weight=state_dict["labels"][label].get("font-weight")
   • Added style=state_dict["labels"][label].get("style")

3. Fixed load_from_input_dict() for dials in DeckController.py:

   • Added the same missing parameters for dial label loading

Files Changed

• src/backend/DeckManagement/Subclasses/KeyLabel.py
• src/backend/DeckManagement/DeckController.py

Testing

The fix ensures that:

• ✅ Font styles (bold/italic) persist after app reload
• ✅ Font styles transfer correctly when moving labels between buttons
• ✅ Font styles are properly cleared when using reset functionality
• ✅ All font attributes (family, size, weight, style) are consistently loaded and saved

Technical Details

The KeyLabel dataclass already had the style field defined, but it wasn't being populated during the JSON loading process. This meant that even though the font style was correctly saved to the page configuration, it was lost when the application restarted or when labels were moved between different inputs.
