Detailed Description

GBoard is intended to be used as a log sink and viewer:

• Append-only ingestion: new log lines are added through appendLog().
• Filtering: a search field filters the displayed content without losing the underlying log history.
• User actions: clear (remove all stored lines) and save (export to a file).

Data model and display strategy

• fullLogLines is the source of truth for all received log lines (stored as HTML fragments).
• New lines are appended in batches on the GUI event loop; history is rebuilt only when the filter changes.

Threading notes

In typical usage, log lines may arrive from non-GUI threads. The implementation ensures the actual QTextEdit update is executed on the GUI thread.

Ownership and lifetime

This widget owns its Qt child widgets (created with this as parent).

Constructor & Destructor Documentation

GBoard() [1/3]

GBoard::GBoard ( const std::shared_ptr< GOptions > & gopt, QWidget * parent = nullptr )

explicit

The widget instantiates its internal UI:

• search line edit (filter)
• clear button
• save button
• log display area (QTextEdit, read-only, rich-text enabled)

Parameters

gopt	Shared pointer to the module options/logging configuration.
parent	Parent widget (default is nullptr).

Member Function Documentation

appendLog()

void GBoard::appendLog

(

const QString &

text

)

The input is treated as an HTML fragment (not a full HTML document):

• It is stored verbatim into fullLogLines.
• One queued update appends new matching lines when the GUI event loop resumes.

Empty or whitespace-only fragments are ignored.

Parameters

text	HTML fragment representing one log line.
