Package jmri.jmrit.beantable.sensor

Class SensorTableDataModel.ImageIconRenderer

java.lang.Object

javax.swing.AbstractCellEditor

jmri.jmrit.beantable.sensor.SensorTableDataModel.ImageIconRenderer

All Implemented Interfaces:

Serializable, CellEditor, TableCellEditor, TableCellRenderer

Enclosing class:

SensorTableDataModel

static class SensorTableDataModel.ImageIconRenderer
extends AbstractCellEditor
implements TableCellEditor, TableCellRenderer

Visualize state in table as a graphic, customized for Sensors (2 states). Renderer and Editor are identical, as the cell contents are not actually edited, only used to toggle state using SensorTableDataModel.clickOn(jmri.Sensor).

A single label is reused for every cell and the icons are loaded once per JVM, so rendering a cell allocates nothing. The label ignores revalidate/repaint requests and the row height is set once in SensorTableDataModel.configureTable(javax.swing.JTable): painting a cell must never schedule more painting, or the table repaints itself forever.
