# Compact Layout Update - memoQ Style

**Date:** October 29, 2025
**Version:** Match Display v2 (Compact)
**Status:** ✅ Complete and Tested

## Overview

Redesigned the match display to be **much more compact**, following memoQ's professional interface design. Eliminated wasted space and improved visual hierarchy.

## Changes Made

### 1. **Match Number Positioning**
**Before:**
```
#1
TM
An error message will pop up...
Er verschijnt een foutmelding...
```

**After:**
```
#1  An error message...  |  Er verschijnt een foutmelding...
             95%
```

- ✅ Number moved to LEFT on same line (not above)
- ✅ Saves 1-2 lines per match
- ✅ Much more compact layout

### 2. **Removed Text Labels**
**Before:**
- "Source" label (redundant, wastes line)
- "Target" label (redundant, wastes line)
- "TM" text label (visible through color)

**After:**
- No labels - obvious from context
- Source: light blue background
- Target: light green background
- Match type: border color coding

### 3. **Color-Coded Match Types**
Replaced text labels with professional color coding (like memoQ):

| Match Type | Color | Hex Value |
|------------|-------|-----------|
| TM Match | Red | `#ff6b6b` |
| Termbase | Blue | `#4d94ff` |
| MT (Machine Translation) | Green | `#51cf66` |
| NT (New Translation) | Gray | `#adb5bd` |

**Visual State:**
- **Unselected:** Light tint with thin colored border
- **Selected:** Darker match type color with white text, thick border
- **Hover:** Slightly darker light tint

### 4. **Compact Spacing**
- Margins reduced: 6px → 4px (header), 8px → 4px (content)
- Spacing reduced: 2px → 1px (vertical), 8px → 4px (horizontal)
- No padding waste around source/target boxes
- Max height for text: 35px (compacted from previous)

### 5. **Simplified Header**
**Before:**
```
#1 | TM | [empty space] | 95%
```

**After:** (Integrated into frame)
```
#1  [Source] | [Target]
                    95%
```

Relevance percentage now on bottom right of match item, not top.

## Space Savings

### Example: 3 Matches

**Before (Old Layout):**
```
Match 1:  5 lines of height
Match 2:  5 lines of height  
Match 3:  5 lines of height
─────────────────────────
Total:   15 lines
```

**After (Compact Layout):**
```
Match 1:  2 lines of height
Match 2:  2 lines of height
Match 3:  2 lines of height
─────────────────────────
Total:   6 lines (60% space reduction!)
```

## Implementation Details

### Color Helpers

Added two static methods for color manipulation:

```python
@staticmethod
def _lighten_color(hex_color: str, factor: float) -> str:
    """Lighten a hex color - used for unselected states"""
    # Blends color toward white

@staticmethod
def _darken_color(hex_color: str, factor: float = 0.7) -> str:
    """Darken a hex color - used for selected states"""
    # Blends color toward black
```

This creates consistent visual feedback based on match type.

### Frame Structure

```
CompactMatchItem (border=type_color)
├─ content_layout (horizontal)
│  ├─ #1 (number label)
│  ├─ source_frame (light blue)
│  │  └─ source_text
│  └─ target_frame (light green)
│     └─ target_text
└─ rel_layout (horizontal)
   └─ 95% (relevance)
```

## Visual Comparison

### Old Layout (Verbose)
```
┌─────────────────────────────────┐
│ #1     TM                 95%   │  ← Header line
├─────────────────────────────────┤
│ Source                          │  ← Label line
│ An error message will pop up    │
│ when an error occurs to the     │  ← Content
│ network                         │
├─────────────────────────────────┤
│ Target                          │  ← Label line
│ Er verschijnt een foutmelding   │
│ wanneer er een netwerkfout      │  ← Content
│ optreedt                        │
└─────────────────────────────────┘
Total: ~10 lines per match
```

### New Layout (Compact)
```
┌────────────────┬────────────────┐
│ #1 An error    │ Er verschijnt  │  ← Number + both texts on same line
│ message will   │ een            │
│ pop up...      │ foutmelding... │
├────────────────┼────────────────┤
│                            95%  │  ← Compact relevance
└────────────────┴────────────────┘
Total: ~2-3 lines per match
```

## Browser Color Legend

When viewing matches in the panel, the **border color** indicates match type:

- 🔴 **Red Border** = TM (Translation Memory) - Previously approved translations
- 🔵 **Blue Border** = Termbase - Glossary/terminology matches  
- 🟢 **Green Border** = MT (Machine Translation)
- ⚫ **Gray Border** = NT (New Translation)

**When Selected:**
- Background fills with the match type color
- Text becomes white
- Border becomes darker shade

## Testing Results

✅ Application launches cleanly
✅ No encoding errors
✅ Matches display with compact layout
✅ Color coding visible
✅ Numbers on left side, same line as text
✅ No "Source"/"Target" labels
✅ No "TM" text (replaced by red color)
✅ Keyboard navigation works
✅ Match insertion functional
✅ All visual states (unselected/hover/selected) working

## Files Modified

- `modules/translation_results_panel.py` (CompactMatchItem class)
  - Updated layout structure
  - Added color-coded styling based on match type
  - Added color helper methods
  - Removed redundant labels
  - Optimized spacing and margins

## Backward Compatibility

✅ No breaking changes
✅ All existing signals maintained
✅ Keyboard shortcuts still functional
✅ Match insertion still works
✅ MatchSection and TranslationResultsPanel unchanged

## Notes

- Match type colors are professional and intuitive
- Red for TM follows industry standard (important/approved)
- Blue for terminology (reference)
- Space savings enable viewing more matches at once
- Cleaner visual hierarchy without text clutter
- Matches memoQ's professional, minimal aesthetic

## Next Steps (Optional)

Future enhancements could include:
- Diff highlighting in source/target if differences exist
- Hover tooltip showing full match metadata
- Quick stats (matches per type in section header)
- Font size adjustment slider for accessibility
