public class DefaultTableCellRenderer
extends JLabel
implements TableCellRenderer, Serializable

Port of DefaultTableCellRenderer. Extends JLabel so its peer is the SJLabel surrogate (a real Vaadin Component), satisfying the SJTable bridge's "return a Component-shaped emulator" requirement.

The body is intentionally minimal: getTableCellRendererComponent just routes the value through setValue(Object) (which writes the cell text via JLabel.setText(String)). The selection-foreground / background / font / border-on-focus chrome JDK applies via UIManager defaults is not applied here. R_vaadin_first-acceptable: Vaadin Grid owns the row-selection theme, and our migration shape is "list view + edit form" where in-cell selection chrome rarely matters.

JDK has a static nested DefaultTableCellRenderer.UIResource subclass for L&F-internal sourcing — dropped per R_match_swing_errors sub-bucket (b) (L&F dispatch is permanent). The performance-no-op overrides JDK carries (validate / invalidate / revalidate / repaint / firePropertyChange filter) are preserved verbatim per R_swing_is_truth — they're inert in our world but keep the JDK shape intact for migrated user-subclasses.

getTableCellRendererComponent

public Component getTableCellRendererComponent(JTable table,
 Object value,
 boolean isSelected,
 boolean hasFocus,
 int row,
 int column)

Description copied from interface: TableCellRenderer

Build the rendering component for value.

Specified by:

getTableCellRendererComponent in interface TableCellRenderer

Parameters:

table - the rendering host — emulator JTable in emulator-flow, null from pure-surrogate contexts.

value - the cell value to render. null is valid.

isSelected - true if the cell is to be rendered with the selection highlighted.

hasFocus - true if the cell has keyboard focus. Vaadin Grid has no per-cell focus signal at render time; the SJTable bridge always passes false (R_vaadin_first sub-bucket (c)).

row - the row index of the cell being drawn. When drawing a column header, the value is -1.

column - the column index of the cell being drawn.

firePropertyChange

public void firePropertyChange(String propertyName,
 boolean oldValue,
 boolean newValue)

Overrides:

firePropertyChange in class JComponent

setValue

protected void setValue(Object value)

Sets the cell's text from value. Migrated subclasses commonly override this hook to format values differently (currency, dates, yes/no) — the canonical "DefaultTableCellRenderer subclass" pattern.
