| 25 | /**
|
|---|
| 26 | * This class creates a table cell that features two checkboxes, Upload and Save. It
|
|---|
| 27 | * handles everything on its own, in other words it renders itself and also functions
|
|---|
| 28 | * as editor so the checkboxes may be set by the user.
|
|---|
| 29 | *
|
|---|
| 30 | * Intended usage is like this:
|
|---|
| 31 | * <code>
|
|---|
| 32 | * <br>ActionFlagsTableCell aftc = new ActionFlagsTableCell();
|
|---|
| 33 | * <br>col = new TableColumn(0);
|
|---|
| 34 | * <br>col.setCellRenderer(aftc);
|
|---|
| 35 | * <br>col.setCellEditor(aftc);
|
|---|
| 36 | * </code>
|
|---|
| 37 | *
|
|---|
| 38 | * Note: Do not use the same object both as <code>TableCellRenderer</code> and
|
|---|
| 39 | * <code>TableCellEditor</code> - this can mess up the current editor component
|
|---|
| 40 | * by subsequent calls to the renderer (#19995 and #12462).
