17. 54. 1. 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();



  }
