void handleAnimation();
|
||||
};
|
||||
|
||||
// Cursor animation
|
||||
void Q20CursorManager::animateCursor()
|
||||
{
|
||||
if (currentPosition != targetPosition) {
|
||||
QPointF delta = targetPosition - currentPosition;
|
||||
currentPosition += delta * 0.1; // Smooth interpolation
|
||||
|
||||
if (QLineF(currentPosition, targetPosition).length() < 1) {
|
||||
currentPosition = targetPosition;
|
||||
}
|

## 📊 Deliverables
|
||||
|
||||
### 5.5 Complete Telephony Stack
|
||||
**Requirements:**
|
||||
- Functional modem integration
|
||||
- Voice call system working
|
||||
- SMS messaging system
|
||||
- Data connectivity
|
||||
- Network management
|
||||
|
||||
### 5.6 Telephony Applications
|
||||
**Components:**
|
||||
- Phone dialer application
|
||||
- SMS messaging application
|
||||
- Contacts management
|
||||
- Call history
|
||||
- Network settings
|
||||
|
||||
### 5.7 Integration Layer
|
||||
**Features:**
|
||||
- Modem abstraction layer
|
||||
- Service management
|
||||
- Event handling
|
||||
- Error recovery
|
||||
- Power management
|
||||
|
||||
## ⏱️ Timeline
|
||||
|
||||
**Week 1-2**: Modem integration
|
||||
**Week 3-4**: Voice call system
|
||||
**Week 5-6**: SMS system
|
||||
**Week 7-8**: Data connectivity
|
||||
**Week 9-10**: Network management
|
||||
**Week 11-12**: Testing and integration
|
||||
|
||||
**Total Duration**: 12 weeks (3 months)
|
||||
|
||||
## 🎯 Success Criteria
|
||||
|
||||
Phase 5 is successful when:
|
||||
1. Complete telephony stack is functional
|
||||
2. Voice calls work reliably
|
||||
3. SMS messaging is operational
|
||||
4. Data connectivity is stable
|
||||
5. Network management is complete
|
||||
|
||||
## 🚨 Risk Mitigation
|
||||
|
||||
**High-Risk Scenarios:**
|
||||
- Modem firmware issues → Extract and analyze firmware blobs
|
||||
- QMI protocol complexity → Implement comprehensive testing
|
||||
- Audio routing problems → Develop fallback audio paths
|
||||
- Network connectivity issues → Implement robust error handling
|
||||
- SMS storage problems → Use reliable storage backend
