Stream monitor

Stream monitoring: multi-tab data/image/command/message monitoring and single-stream panels.

Overview

quatm/GUI/streammonitor/ provides the stream monitor: MainWindow uses tabs to hold monitors for data streams (Data), image streams (Image), commands (Command), message logs (Message) and history (History), among others; each monitor tab is a StreamMonitor that subscribes to a single data stream and displays it in real time.

Components

Component	Description
`MainWindow`	Monitoring main window: multi-tab container + menu
`StreamMonitor`	Single-stream monitoring panel: subscribes to one data stream and displays it in real time
`MessageTableModel`	Message log table model (timestamp/source/level/content, colored by level)
`ImageTableModel`	Image stream metadata table (fixed time/source columns + dynamic key columns)
`AutoSortProxyModel`	Auto-sorting proxy model ordered by descending timestamp

Monitoring types

Tab	Content
Data	Real-time curves/tables of numeric data streams
Image	Scientific image streams and their metadata
Command	Command / instruction streams
Message	Message log (timestamp/source/level/content)
History	Historical records

Usage

from quatm.GUI.streammonitor import MainWindow, StreamMonitor

win = MainWindow(parent=parent)   # multi-tab monitoring main window
panel = StreamMonitor(name="PMT", stream_type="Data", parent=parent)  # single-stream panel

This monitoring interface is normally started as a standalone process; the single-stream StreamMonitor panel can also be embedded in other windows.
