# EU-Utility Bug Fix Report
|
|
|
|
## Summary
|
|
This document details all bugs, errors, and issues fixed in the EU-Utility codebase during the bug hunting session.
|
|
|
|

|
|
|
|
## Fixed Issues
|
|
|
|
### 1. **Missing QAction Import in activity_bar.py**
|
|
**File:** `core/activity_bar.py`
|
|
**Line:** 5
|
|
**Issue:** `QAction` was used in `_show_context_menu()` method but not imported from `PyQt6.QtGui`.
|
|
**Fix:** Added `QAction` to the imports from `PyQt6.QtGui`.
|
|
|
|
```python
|
|
# Before:
|
|
from PyQt6.QtGui import QMouseEvent, QPainter, QColor, QFont, QIcon, QPixmap
|
|
|
|
# After:
|
|
from PyQt6.QtGui import QMouseEvent, QPainter, QColor, QFont, QIcon, QPixmap, QAction
|
|
```
|
|
|

|
|
|
|
### 2. **Invalid QPropertyAnimation Property (windowOpacity) in perfect_ux.py**
|
|
**File:** `core/perfect_ux.py`
|
|
**Line:** 904-930
|
|
**Issue:** The `_animate_transition()` method used `b"windowOpacity"` as a property for QPropertyAnimation, but `windowOpacity` is not a valid animatable property on QWidget in Qt6. This would cause runtime errors when switching views.
|
|
**Fix:** Added `QGraphicsOpacityEffect` and modified the animation to animate the `opacity` property of the effect instead of the widget directly.
|
|
|
|
```python
|
|
# Before:
|
|
fade_out = QPropertyAnimation(current, b"windowOpacity")
|
|
|
|
# After:
|
|
current._opacity_effect = QGraphicsOpacityEffect(current)
|
|
current.setGraphicsEffect(current._opacity_effect)
|
|
fade_out = QPropertyAnimation(current._opacity_effect, b"opacity")
|
|
```
|
|
|
|

|
|
|
|
### 3. **Invalid QPropertyAnimation Property (windowOpacity) in overlay_window.py**
|
|
**File:** `core/overlay_window.py`
|
|
**Line:** 527-540
|
|
**Issue:** Same issue as above - `windowOpacity` property cannot be animated directly on QWidget in Qt6.
|
|
**Fix:** Created a `QGraphicsOpacityEffect` for the window and animated its `opacity` property.
|
|
|

|
|
|
|
### 4. **Missing show()/hide() Methods in TrayIcon**
|
|
**File:** `core/tray_icon.py`
|
|
**Line:** 61-79
|
|
**Issue:** The `TrayIcon` class inherited from `QWidget` but didn't implement `show()` and `hide()` methods that delegate to the internal `QSystemTrayIcon`. Other code expected these methods to exist.
|
|
**Fix:** Added `show()`, `hide()`, and `isVisible()` methods that properly delegate to the internal tray icon.
|
|
|
|
```python
|
|
def show(self):
|
|
"""Show the tray icon."""
|
|
if self.tray_icon:
|
|
self.tray_icon.show()
|
|
|
|
def hide(self):
|
|
"""Hide the tray icon."""
|
|
if self.tray_icon:
|
|
self.tray_icon.hide()
|
|
|
|
def isVisible(self):
|
|
"""Check if tray icon is visible."""
|
|
return self.tray_icon.isVisible() if self.tray_icon else False
|
|
```
|
|
|

|
|
|
### 5. **Qt6 AA_EnableHighDpiScaling Deprecation Warning**
|
|
**File:** `core/main.py`
|
|
**Line:** 81-86
|
|
**Issue:** The `Qt.AA_EnableHighDpiScaling` attribute is deprecated in Qt6 and always enabled by default. While the existing code didn't cause errors due to the `hasattr` check, it was unnecessary.
|
|
**Fix:** Added proper try/except handling and comments explaining the Qt6 compatibility.
|
|
|
|
```python
|
|
# Enable high DPI scaling (Qt6 has this enabled by default)
|
|
# This block is kept for backwards compatibility with Qt5 if ever needed
|
|
if hasattr(Qt, 'AA_EnableHighDpiScaling'):
|
|
try:
|
|
self.app.setAttribute(Qt.ApplicationAttribute.AA_EnableHighDpiScaling)
|
|
except (AttributeError, TypeError):
|
|
pass # Qt6+ doesn't need this
|
|
```
|
|
|
|
---
|
|
|
|
### 6. **Unsafe Attribute Access in Activity Bar**
|
|
**File:** `core/activity_bar.py`
|
|
**Lines:** Multiple locations
|
|
**Issue:** Various methods accessed `plugin_class.name`, `self.drawer`, and other attributes without checking if they exist first. This could cause `AttributeError` exceptions.
|
|
**Fix:** Added `getattr()` calls with default values throughout:
|
|
|
|
```python
|
|
# Before:
|
|
plugin_name = plugin_class.name
|
|
|
|
# After:
|
|
plugin_name = getattr(plugin_class, 'name', plugin_id)
|
|
```
|
|
|
|
Also added `hasattr()` checks for `self.drawer` before accessing it.
|
|
|

|
|
|
|
### 7. **Missing Error Handling in Activity Bar Initialization**
|
|
**File:** `core/main.py`
|
|
**Line:** 127-139
|
|
**Issue:** Activity Bar initialization was not wrapped in try/except, so any error during creation would crash the entire application.
|
|
**Fix:** Wrapped the activity bar creation and initialization in a try/except block with proper error messages.
|
|
|
|
```python
|
|
try:
|
|
from core.activity_bar import get_activity_bar
|
|
self.activity_bar = get_activity_bar(self.plugin_manager)
|
|
if self.activity_bar:
|
|
if self.activity_bar.config.enabled:
|
|
# ... setup code ...
|
|
else:
|
|
print("[Core] Activity Bar disabled in config")
|
|
else:
|
|
print("[Core] Activity Bar not available")
|
|
self.activity_bar = None
|
|
except Exception as e:
|
|
print(f"[Core] Failed to create Activity Bar: {e}")
|
|
self.activity_bar = None
|
|
```
|
|
|

|
|
### 8. **Missing Error Handling in EU Focus Detection**
|
|
**File:** `core/main.py`
|
|
**Line:** 405-450
|
|
**Issue:** The `_check_eu_focus()` method had unsafe attribute access and could fail if `window_manager` or `activity_bar` were not properly initialized.
|
|
**Fix:** Added comprehensive error handling with `hasattr()` checks and try/except blocks around all UI operations.
|
|
|
|
---
|
|
|
|
### 9. **Unsafe Attribute Access in Plugin Manager**
|
|
**File:** `core/plugin_manager.py`
|
|
**Lines:** Multiple locations
|
|
**Issue:** Plugin loading code accessed `plugin_class.name` and `plugin_class.__name__` without checking if these attributes exist, and didn't handle cases where plugin classes might be malformed.
|
|
**Fix:** Added safe attribute access with `getattr()` and `hasattr()` checks throughout the plugin loading pipeline.
|
|
|
|
```python
|
|
# Before:
|
|
print(f"[PluginManager] Skipping disabled plugin: {plugin_class.name}")
|
|
|
|
# After:
|
|
plugin_name = getattr(plugin_class, 'name', plugin_class.__name__ if hasattr(plugin_class, '__name__') else 'Unknown')
|
|
print(f"[PluginManager] Skipping disabled plugin: {plugin_name}")
|
|
```
|
|
|

|
|
|
|
### 10. **Missing Error Handling in _toggle_activity_bar**
|
|
**File:** `core/main.py`
|
|
**Line:** 390-403
|
|
**Issue:** The `_toggle_activity_bar()` method didn't check if `activity_bar` and `tray_icon` exist before calling methods on them.
|
|
**Fix:** Added `hasattr()` checks and try/except blocks.
|
|
|
|
```python
|
|
def _toggle_activity_bar(self):
|
|
if hasattr(self, 'activity_bar') and self.activity_bar:
|
|
try:
|
|
if self.activity_bar.isVisible():
|
|
self.activity_bar.hide()
|
|
if hasattr(self, 'tray_icon') and self.tray_icon:
|
|
self.tray_icon.set_activity_bar_checked(False)
|
|
# ...
|
|
```
|
|
|
|
---
|
|
|
|
### 11. **Missing Error Handling in Drawer Methods**
|
|
**File:** `core/activity_bar.py`
|
|
**Lines:** 269-275, 373-377
|
|
**Issue:** The `_toggle_drawer()` and `_on_drawer_item_clicked()` methods didn't have error handling for drawer operations.
|
|
**Fix:** Added try/except blocks with error logging.
|
|

## Testing Recommendations
|
|
|
|
After applying these fixes, test the following critical paths:
|
|
|
|
1. **App Startup**
|
|
- Launch the application
|
|
- Verify no import errors occur
|
|
- Check that the dashboard opens correctly
|
|
|
|
2. **Dashboard Navigation**
|
|
- Click through all navigation items (Dashboard, Plugins, Widgets, Settings)
|
|
- Verify view transitions work without errors
|
|
|
|
3. **Activity Bar**
|
|
- Toggle activity bar visibility from tray menu
|
|
- Click on pinned plugins
|
|
- Open the drawer and click on plugins
|
|
- Test auto-hide functionality
|
|
|
|
4. **Tray Icon**
|
|
- Right-click tray icon to open menu
|
|
- Click "Dashboard" to toggle visibility
|
|
- Click "Quit" to exit the application
|
|
|
|
5. **Plugin Loading**
|
|
- Enable/disable plugins
|
|
- Verify plugins load without errors
|
|
- Check plugin UI displays correctly
|
