Interface TableCellRenderer

All Known Implementing Classes:

DefaultTableCellRenderer

public interface TableCellRenderer

Port of TableCellRenderer. Returns Component so the renderer hands back our emulator's Component hierarchy — JDK's java.awt.Component return type is incompatible with our hierarchy and is the central reason this interface is ported wholesale rather than reused (D_event_port_policy + the cell-renderer carve-out). Mirrors the ListCellRenderer stance for the same reason.

The table parameter is typed JTable and arrives differently from the two bridges (see @param table). A renderer that doesn't read the table (the common-case DefaultTableCellRenderer pattern: just format the value) works unchanged; one reading table.getSelectionForeground() or similar NPEs in the pure-surrogate path where table is null.

Method Details

getTableCellRendererComponent

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

Build the rendering component for value.

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.
