public class SJTable extends com.vaadin.flow.component.grid.Grid<Integer> implements JComponentMixin, TableModelListener, TableColumnModelListener, ListSelectionListener
Surrogate for JTable (SD_sjtable). Extends Vaadin Grid<Integer> — row indices are the Grid's items, which keeps the installed TableModel as the single source of truth (R_swing_is_truth) and lets setValueAt updates reflect on next render without snapshot rebuilds.

Vaadin-first rendering (R_vaadin_first)

Surrogate-layer code uses Vaadin's Renderer surface for column rendering — install via setRenderer(int, Renderer). The JDK TableCellRenderer surface (return type java.awt.Component clashes with our hierarchy per D_event_port_policy) lives only on the emulator layer (:emulators.JTable); the emulator translates its ported vaadinx.swing.table.TableCellRenderer registry into Vaadin renderers and installs via setRenderer(int, Renderer). Pure-surrogate users without setRenderer(int, Renderer) get a default value.toString() Span renderer for every column — matches the SJComboBox precedent (default setItemLabelGenerator with String.valueOf).

Row-index identity

Each Vaadin row carries the boxed Integer index into the model. Per-cell renderer reads model.getValueAt(row, modelCol) live, so fireTableRowsUpdated just calls dataProvider.refreshItem(row) — no array-snapshot resync. The ListSelectionModel is index-based already, so the bridge to Vaadin Grid's selection (which carries the same Integer keys) is direct.

Listener-list architecture

SJTable IS-A TableModelListener / TableColumnModelListener / ListSelectionListener — JDK JTable's pattern. The surrogate subscribes itself to the installed model, column model, and selection model on install/swap; user code subscribes directly to those models (no surrogate-level convenience listener registration). The internal subscriptions handle (a) column rebuild on structure change, (b) Grid data refresh on row change, (c) Grid selection push on selection-model change. Vaadin → us flows via a addSelectionListener subscription wrapped in SHelper.callSwing(Runnable) (R_callswing_envelope) and writes through to ListSelectionModel, closing the loop.

R_vaadin_first drop-and-WARN surface

Cell-editor surface (R_match_swing_errors sub-bucket (b)), TableRowSorter / RowFilter (deferred), dragEnabled / dropMode (cross-cutting DnD), column-cell selection (Vaadin Grid is row-only), intercellSpacing / gridColor / showHorizontalLines (Vaadin theme owns chrome), rowHeight on push (Vaadin auto- heights), printing (permanent sub-bucket (b)).

    • getListSelectionModel

      public ListSelectionModel getListSelectionModel()
      JDK getSelectionModel(): ListSelectionModel can't coexist with Vaadin Grid's same-named getSelectionModel(): GridSelectionModel<T> (different return types, can't override). Per R_vaadin_first the Vaadin shape wins at the surrogate layer; pure-surrogate code reads selection via setSelectionMode(int) / setRowSelectionInterval(int, int) / getSelectedRow() instead. The emulator layer (:emulators.JTable) keeps the JDK-shaped getter for stage-2 import-swap compatibility — and reaches the JDK model through getListSelectionModel() below.

    • getJdkSelectionMode

      public int getJdkSelectionMode()
      Accessor for the current JDK selection mode (one of ListSelectionModel.SINGLE_SELECTION / SINGLE_INTERVAL_SELECTION / MULTIPLE_INTERVAL_SELECTION). Distinct name from any Vaadin Grid getter (Vaadin Grid 25 has no public getSelectionMode(), but the differing name future-proofs). Used by the emulator layer to read the previous mode for PCE delivery on setSelectionMode(int) swaps.

      public int convertRowIndexToView(int modelRowIndex)
      Routes through the installed RowSorter when present; identity otherwise.

    • convertRowIndexToModel

      public int convertRowIndexToModel(int viewRowIndex)
      Routes through the installed RowSorter when present; identity otherwise.

    • setRenderer

      public void setRenderer(int viewColumnIndex, com.vaadin.flow.data.renderer.Renderer<Integer> renderer)
      Vaadin-first cell renderer install per R_vaadin_first. Replaces the column at viewColumnIndex with one driven by the supplied Vaadin Renderer<Integer>. The header text and key are preserved across the swap. Migrated code at the surrogate stage uses this rather than the JDK TableCellRenderer surface (which lives only on the emulator layer per D_event_port_policy + R_vaadin_first).

      Throws IndexOutOfBoundsException when viewColumnIndex is out of range — matches Vaadin's column accessors.

      Swaps the renderer in place via Grid.Column.setRenderer(Renderer): the Grid.Column instance persists, so header / key / sortability / sort property / column order — and any setEditorComponent — are all preserved automatically, and the swap is churn-free (safe to call repeatedly, e.g. the emulator re-installs renderers on every setDefaultRenderer / per-column renderer change).

    • createDefaultColumnsFromModel

      public void createDefaultColumnsFromModel()
      Rebuild the TableColumnModel from the current TableModel's structure. Called when autoCreateColumnsFromModel is true and the model fires a HEADER_ROW TableModelEvent.

    • tableChanged

      public void tableChanged(TableModelEvent e)
      Applies a model change to the sorter, the selection and the Grid, in that order.

      The installed RowSorter hears the change first, because nothing else tells it: TableRowSorter does not listen to its model, it is the table's job to forward every event. Until told, it keeps answering getViewRowCount() and the index conversions from the rows it last saw, and count(Query) and fetch(Query) read through it.

      The selection needs no re-mapping across the change: it holds model rows (D_jtable_cell_editing), so a re-sort leaves it valid, and inserts and deletes shift it here in model coordinates.

      Hops onto the owner's UI thread, since a worker filling the model is the ordinary Swing pattern (SD_background_model_hop).

    • setRefreshProtectedRow

      public void setRefreshProtectedRow(Integer modelRow)
      Protect (or, with null, un-protect) a model row from refreshItem on UPDATE events. The emulator's cell-editing lifecycle drives this so an external setValueAt can't re-render the row hosting an open editor (D_jtable_cell_editing Task 2). Machinery, not editing API.

    • isEditorClosingForDataChange

      public boolean isEditorClosingForDataChange()
      Whether an EditorCloseListener running now was fired because the Grid's data changed — Vaadin closes an open editor on every data change, refreshAll() included — rather than because the user left the cell. Machinery for the emulator, whose JDK contract keeps an edit open across a model change; not editing API.

    • setSelectionMode

      public void setSelectionMode(int selectionMode)
      JDK selection-mode setter. Validates per JDK contract (throws IAE on unrecognised mode), updates the underlying ListSelectionModel, and maps to Vaadin Grid's Grid.SelectionMode: SINGLE → SINGLE; the two interval modes both map to MULTI since Vaadin Grid has no single-interval analog. The ListSelectionModel still enforces the JDK contract; the divergence is browser-side ctrl-click extending past the interval — the model rejects the second selection so the UI reverts.

    • getRowSorter

      public RowSorter<? extends TableModel> getRowSorter()
      Returns the currently installed JDK RowSorter, or null when no sort is active. Migrators read this to inspect getSortKeys() or to call toggleSortOrder(column) programmatically.

    • setRowSorter

      public void setRowSorter(RowSorter<? extends TableModel> newRowSorter)
      Install a JDK RowSorter on this table. null clears sort entirely (subsequent Vaadin Grid header clicks fall back to model order). Detaches our RowSorterListener from the old sorter and attaches a fresh one to the new — programmatic rowSorter.setSortKeys(...) calls are bridged back to Vaadin via the listener (which calls grid.sort(translated) so the Grid's sort indicator stays in sync).

    • removeEditor

      public void removeEditor()

    • addMouseListener

      public void addMouseListener(SMouseListener l)
      Overrides the inherited ComponentMixin wire — Grid dispatches item clicks carrying the row item + clicked column, not generic component clicks. Each SMouseListener gets two Grid subscriptions combined into one Registration: addItemClickListener fires SMouseEvent.MOUSE_CLICKED with the browser click count, addItemDoubleClickListener fires it with clickCount == 2 — the double-click-to-edit/open idiom. The clicked row (the Grid item, consistent with getSelectedRow() / getValueAt(int, int)) and the view-column index are stashed around the fan-out so rowAtPoint(Point) / columnAtPoint(Point) resolve during the user's mouseClicked handler (R_layouts_close_enough — no pixel→cell map). Mirrors SJList (SD_sjlist); columnAtPoint is the bonus Grid's item-click column affords that SJList didn't need.
      Specified by:
      addMouseListener in interface ComponentMixin

    • rowAtPoint

      public int rowAtPoint(Point point)
      Row index of the cell currently being click-dispatched (stashed by addMouseListener(SMouseListener)'s item-click wire), or -1 outside a dispatch. Consistent with getSelectedRow() / getValueAt(int, int) — there is no server-side pixel→row map (R_layouts_close_enough). Graduates from the pre-(b) drop-and-WARN.

    • columnAtPoint

      public int columnAtPoint(Point point)
      View-column index of the cell currently being click-dispatched, or -1 (outside a dispatch, or a row-only click that carries no column). Resolved from the Grid's clicked column (R_layouts_close_enough).
