| 17. 54. 1. 使用TableEditor |
|
|
- TableEditor derives from ControlEditor.
- TableEditor belongs to a cell.
- Use the setters for row and column to set the cell, like this:
|
|
TableEditor editor = new TableEditor(myTable);
editor.setEditor(myControl);
editor.setItem(myItem);
editor.setColumn(myColumn);
|
|
You can also use TableEditor's new setEditor() method that takes three parameters-an editor,
an item, and a column-to set everything in one call, like this: |
|
TableEditor editor = new TableEditor(myTable);
editor.setEditor(myControl, myItem, myColumn);
