Detailed Description

A QWidget containing a QTabWidget with two tabs — Nodes and Edges — each backed by a sortable, searchable table view.

Call refresh() whenever the graph data changes and the panel is visible. The widget itself does not auto-refresh; the caller controls when to rebuild the cache.

Constructor & Destructor Documentation

GraphTableWidget()

GraphTableWidget::GraphTableWidget ( QWidget *  parent = nullptr )

explicit

Constructs the GraphTableWidget.

Builds both tabs (Nodes, Edges) with search bar, Refresh button, and a sortable/searchable QTableView backed by a QSortFilterProxyModel.

Member Function Documentation

doExport()

void GraphTableWidget::doExport ( QAbstractItemModel *  proxyModel, const QString &  defaultName, bool  csv  )

private

Opens a save dialog and writes proxyModel via TableExport.

defaultName is used to suggest a filename ("nodes" or "edges"). csv selects CSV (true) or JSON (false) format.

doImport()

void GraphTableWidget::doImport ( bool  forNodes, bool  csv  )

private

Opens DialogImportAttributes and, on acceptance, calls the appropriate Graph import method then refreshes the table.

forNodes true → import node attributes; false → import edge attributes. csv true → CSV format; false → JSON format.

edgeModel()

QAbstractItemModel * GraphTableWidget::edgeModel

(

)

const

Returns the raw (unfiltered) edge source model.

exportEdgesCSV

void GraphTableWidget::exportEdgesCSV ( )

slot

Prompts for a file path and exports visible edge rows as CSV.

exportEdgesJSON

void GraphTableWidget::exportEdgesJSON ( )

slot

Prompts for a file path and exports visible edge rows as JSON.

exportNodesCSV

void GraphTableWidget::exportNodesCSV ( )

slot

Prompts for a file path and exports visible node rows as CSV.

exportNodesJSON

void GraphTableWidget::exportNodesJSON ( )

slot

Prompts for a file path and exports visible node rows as JSON.

exportStatusMessage

void GraphTableWidget::exportStatusMessage ( const QString &  message )

signal

Emitted with a status message after an export attempt.

importEdgesCSV

void GraphTableWidget::importEdgesCSV ( )

slot

Opens the column-mapping dialog and imports edge attributes from a CSV.

importEdgesJSON

void GraphTableWidget::importEdgesJSON ( )

slot

Opens the column-mapping dialog and imports edge attributes from a JSON.

importNodesCSV

void GraphTableWidget::importNodesCSV ( )

slot

Opens the column-mapping dialog and imports node attributes from a CSV.

importNodesJSON

void GraphTableWidget::importNodesJSON ( )

slot

Opens the column-mapping dialog and imports node attributes from a JSON.

importStatusMessage

void GraphTableWidget::importStatusMessage ( const QString &  message )

signal

Emitted with a status message after an import attempt.

nodeModel()

QAbstractItemModel * GraphTableWidget::nodeModel

(

)

const

Returns the raw (unfiltered) node source model.

nodeSelected

void GraphTableWidget::nodeSelected ( int  number )

signal

Emitted when the user clicks a row in the Nodes tab.

onNodeRowClicked

void GraphTableWidget::onNodeRowClicked ( const QModelIndex &  proxyIndex )

privateslot

Maps the proxy index to a source index and emits nodeSelected().

refresh

void GraphTableWidget::refresh ( Graph *  graph )

slot

Repopulates both the node and edge models from graph.

Repopulates both models from graph and resizes columns.

Stores a pointer to graph for subsequent Refresh button clicks.
