| 27 | * This class creates a table cell that features two checkboxes, Upload and Save. It

| 28 | * handles everything on its own, in other words it renders itself and also functions
|
|---|
| 29 | * as editor so the checkboxes may be set by the user.
|
|---|
| 30 | *
|
|---|
| 31 | * Intended usage is like this:
|
|---|
| 32 | * ActionFlagsTableCell aftc = new ActionFlagsTableCell();
|
|---|
| 33 | * col = new TableColumn(0);
|
|---|
| 34 | * col.setCellRenderer(aftc);
|
|---|
| 35 | * col.setCellEditor(aftc);
