Using 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); import org.eclipse.swt.SWT; import org.eclipse.swt.custom.TableEditor; import org.eclipse.swt.layout.FillLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; import org.eclipse.swt.widgets.Table; import org.eclipse.swt.widgets.TableColumn; import org.eclipse.swt.widgets.TableItem; public class TableEditorSample {   public static void main(String[] args) {     Display display = new Display();     Shell shell = new Shell(display);     shell.setText("Text Table Editor");     shell.setLayout(new FillLayout());     Table table = new Table(shell, SWT.SINGLE | SWT.FULL_SELECTION | SWT.HIDE_SELECTION);     table.setHeaderVisible(true);     table.setLinesVisible(true);     for (int i = 0; i < 5; i++) {       TableColumn column = new TableColumn(table, SWT.CENTER);       column.setText("Column " + (i + 1));       column.pack();     }     // Create five table editors for color     TableEditor[] colorEditors = new TableEditor[5];     // Create five buttons for changing color     Button[] colorButtons = new Button[5];     for (int i = 0; i < 5; i++) {       final TableItem item = new TableItem(table, SWT.NONE);       // Create the editor and button       colorEditors[i] = new TableEditor(table);       colorButtons[i] = new Button(table, SWT.PUSH);       // Set attributes of the button       colorButtons[i].setText("Color...");       colorButtons[i].computeSize(SWT.DEFAULT, table.getItemHeight());       // Set attributes of the editor       colorEditors[i].grabHorizontal = true;       colorEditors[i].minimumHeight = colorButtons[i].getSize().y;       colorEditors[i].minimumWidth = colorButtons[i].getSize().x;       // Set the editor for the first column in the row       colorEditors[i].setEditor(colorButtons[i], item, 0);     }     shell.pack();     shell.open();     while (!shell.isDisposed()) {       if (!display.readAndDispatch()) {         display.sleep();       }     }     display.dispose();   } }
