# Termbase & Match Display - Major UI Improvements

## Changes Completed Today

### 1. ✅ Fixed Black Segment Numbers After Navigation
**File**: `Supervertaler_Qt.py` (line ~2825)
**Issue**: Previously visited segment numbers stayed black
**Fix**: Added explicit foreground color reset when clearing previous selection
```python
prev_id_item.setForeground(QColor("black"))  # Reset text color to black
```
**Result**: Segment numbers now properly highlight in orange when current, and revert to black text on white background when not selected

---

### 2. ✅ Global Consecutive Numbering for Matches  
**File**: `modules/translation_results_panel.py`
**Issue**: TM matches numbered 1-N, Termbase matches restarted at 1-N (separate sections)
**Fix**: 
- Modified `MatchSection` class to accept `global_number_start` parameter
- Updated `_populate_matches()` to use global numbering
- Updated `set_matches()` to assign consecutive numbers across all sections

**Result**:
```
Before: TM (1-10), Termbases (1-6)
After:  TM (1-10), Termbases (11-16)
```
- Ctrl+1 through Ctrl+9 now works with global numbering
- Matches display shows correct global number

### 3. ✅ Compact memoQ-Style Match Display
**File**: `modules/translation_results_panel.py` (CompactMatchItem class)
**Changes**:
- Redesigned layout from vertical to horizontal (one-line display)
- Format: `[#] Percentage  Source → Target`
- Removed individual colored frames for source/target
- Only the match number box gets colored (red for TM, blue for Termbase)
- When selected: entire row gets light background + border

**Before**:
```
┌──────────────────────────────────┐
│ [1]                              │
│ Error                    Fout    │
│ 100%                             │
└──────────────────────────────────┘
```

**After**:
```
┌──────────────────────────────┐
│ [1] 100%  error → fout       │
└──────────────────────────────┘
```

**Spacing Reductions**:
- MatchSection margins: 2px → 0px
- MatchSection spacing: 2px → 0px  
- CompactMatchItem margins: 4px → 2px
- CompactMatchItem layout: changed from multi-line to single-line

**Result**: ~40-50% less vertical space wasted, matches show more info per line

### 4. ✅ Improved Match Item Styling
**File**: `modules/translation_results_panel.py` (update_styling method)
**Changes**:
- Unselected: Type-color box for number only, white background for row
- Selected: Type-color number + light background for entire row
- Hover: Subtle background change (#f5f5f5)
- Only the number box gets the red/blue/green color (not entire row)

**Color Scheme**:
- TM: Red (#ff6b6b)
- Termbase: Blue (#4d94ff)
- MT: Green (#51cf66)
- NT: Gray (#adb5bd)

---

### 5. ✅ Fixed Mouse Event Compatibility  
**File**: `modules/translation_results_panel.py`
**Issue**: PyQt6 parameter naming mismatch in `mouseMoveEvent`
**Fix**: Changed parameter from `event` to `a0` to match base class signature

## Testing Checklist

- [x] Segment numbers don't turn black after navigation
- [x] Ctrl+1-9 works with global numbering
- [x] Match display is more compact (one line per match)
- [x] Only match number box gets colored
- [x] Selected match shows light background + border
- [x] No syntax errors in modified files

---

## Known Remaining Work

### Issue 4: Ctrl+Up/Down Navigation for Matches
- Ctrl+Up/Down should navigate through matches
- Plain Up/Down should only navigate grid
- Currently both affect grid

### Issue 5: Dual-Selection System
- Allow selection of individual words in source text
- Use Ctrl+Shift+Arrow to extend selection
- Use Ctrl+G to add term to termbase
- Use Ctrl+Shift+T to add term to TM
- Tab to switch focus between source/target

## Next Steps

1. **Ctrl+Up/Down Navigation** (~1 hour)
   - Add keyboard event handler for Ctrl+Up/Down
   - Forward to TranslationResultsPanel instead of grid
   - Update grid to only respond to plain Up/Down

2. **Dual-Selection System** (~2-3 hours)
   - Refactor source column to support selection mode
   - Add keyboard bindings for Ctrl+Shift+Arrow
   - Implement term pair extraction logic
   - Connect to Ctrl+G and Ctrl+Shift+T shortcuts

3. **Keyboard Navigation** (~30 min)
   - Implement Up/Down arrows to navigate matches within a section
   - Implement Ctrl+Up/Down to navigate matches across sections
   - Implement Enter to insert selected match
