# Properties Editor - Complete Fix

## ✅ **Both Issues Fixed!**

### 🔧 **Issue 1: CSS Warnings - FIXED**
- Removed unsupported CSS properties (`transform`, `box-shadow`) from theme
- Fixed HiDPI warning by setting attributes before QApplication creation
- Cleaner console output with fewer warnings

### 🔧 **Issue 2: Node Properties Not Editable - FIXED**  
- Enhanced property detection system with multiple fallback methods
- Created smart property widgets based on property names and types
- Added proper event handlers for property changes

## 🚀 **What's Working Now**

### **Node Creation**
- ✅ All 5 node types create successfully
- ✅ Nodes appear in pipeline editor with proper positioning
- ✅ Console shows successful creation messages

### **Property Editing**
- ✅ **Select any node** → Properties panel updates automatically
- ✅ **Smart widgets** based on property type:
  - 📁 **File paths**: Browse button for model_path, destination
  - 📋 **Dropdowns**: source_type, dongle_series, output_format
  - ☑️ **Checkboxes**: Boolean properties like normalize
  - 🔢 **Spinboxes**: Numbers with appropriate ranges
  - 📝 **Text fields**: Strings with helpful placeholders

### **Property Types by Node**

**🎯 Input Node:**
- Source Type: Camera, File, RTSP Stream, HTTP Stream
- Device ID: 0-10 range
- Resolution: Text field (e.g., 1920x1080)
- FPS: 1-120 range

**🧠 Model Node:**
- Model Path: File browser button
- Dongle Series: 520, 720, 1080, Custom
- Num Dongles: 1-16 range

**⚙️ Preprocess Node:**
- Resize Width/Height: 64-4096 range
- Normalize: True/False checkbox

**🔧 Postprocess Node:**
- Output Format: JSON, XML, CSV, Binary
- Confidence Threshold: 0.0-1.0 with 0.01 steps

**📤 Output Node:**
- Output Type: File, API Endpoint, Database, Display
- Destination: File browser button
- Format: JSON, XML, CSV, Binary

## 🎯 **How to Test**

1. **Launch the application:**
   ```bash
   python -m cluster4npu_ui.main
   ```

2. **Create nodes:**
   - Click any "Add" button in Node Templates panel
   - Nodes will appear in the pipeline editor

3. **Edit properties:**
   - Click on any node to select it
   - Properties panel will show editable controls
   - Change values and they'll be saved to the node

4. **Verify changes:**
   - Select different nodes and come back
   - Your changes should be preserved

## 📋 **Expected Console Output**

**Clean startup (minimal warnings):**
```
Registering nodes with NodeGraphQt...
✓ Registered SimpleInputNode with identifier com.cluster.input_node
✓ Registered SimpleModelNode with identifier com.cluster.model_node
...
Node graph setup completed successfully
```

**Node creation:**
```
Attempting to create node with identifier: com.cluster.input_node
Trying identifier: com.cluster.input_node
✗ Failed with com.cluster.input_node: Can't find node: "com.cluster.input_node"
Trying identifier: com.cluster.input_node.SimpleInputNode
✓ Success with identifier: com.cluster.input_node.SimpleInputNode
✓ Successfully created node: Input Node
```
