Session Widget - vzug-e-hinge
|
|
|
==============================
|
|
|
PyQt6 GUI widget for session orchestration.
|
|
|
|
|
|
This widget provides the user interface for automated test sessions:
|
|
|
- Load interface and session profiles
|
|
|
- Start/pause/resume/stop session execution
|
|
|
- Display real-time status updates
|
|
|
- Show command progress and packet counts
|
|
|
- Display countdown timers during delays
|
|
|
- Monitor execution via data log
|
|
|
|
|
|
The widget connects to Session class via Qt signals/slots for
|
|
|
asynchronous updates without blocking the GUI.
