Using TableEditor : Table Editor « SWT « Java Tutorial

1. Java Tutorial
2. SWT
3. Table Editor

1. TableEditor derives from ControlEditor.
2. TableEditor belongs to a cell.
3. 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);

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();

  }
}
