If you just change the image 1) you will not have the platform image, 2) you
will not be accessible by screen readers or keyboard access 3) you will have
to write code to detect the mouse down (up?) in the image.
You could create a Button with style SWT.CHECK make it an editor in the
TableEditor:
public static void main (String [] args) {
Display display = new Display ();
Shell shell = new Shell (display);
shell.setLayout(new FillLayout());
Table table = new Table(shell, SWT.BORDER);
table.setHeaderVisible(true);
table.setLinesVisible(true);
TableColumn column0 = new TableColumn(table, SWT.NONE);
TableColumn column1 = new TableColumn(table, SWT.NONE);
TableColumn column2 = new TableColumn(table, SWT.NONE);
int minWidth = 0;
for (int i = 0; i < 100; i++) {
TableItem item = new TableItem(table, SWT.NONE);
item.setText(new String[] {"item "+i, "asdadasd", "sada d
asd asd a dasd"});
if (i %3 == 0 || i % 5 == 0) {
Button b = new Button(table, SWT.CHECK);
b.pack();
TableEditor editor = new TableEditor(table);
Point size = b.computeSize(SWT.DEFAULT,
SWT.DEFAULT);
editor.minimumWidth = size.x;
minWidth = Math.max(size.x, minWidth);
editor.minimumHeight = size.y;
editor.horizontalAlignment = SWT.RIGHT;
editor.verticalAlignment = SWT.CENTER;
if (i % 3 == 0) {
editor.setEditor(b, item , 1);
} else {
editor.setEditor(b, item , 2);
}
}
}
column0.pack();
column1.pack();
column1.setWidth(column1.getWidth() + minWidth);
column2.pack();
column2.setWidth(column2.getWidth() + minWidth);
shell.setSize(300, 300);
shell.open ();
while (!shell.isDisposed ()) {
if (!display.readAndDispatch ()) display.sleep ();
}
display.dispose ();
}

If you are using a JFace TableViewer, you could use a CheckboxCellEditor.

Veronika Irvine:
BTW, when I try in this example scroll table using keyboard
checkboxes don't move and become out of synch with their items. If I use
scrollbar I don't have such problem.
I use 3.1 M5 (M4 has same problem).

Hi Veronika,
Thanks for the advice. I like your suggestion and have implemented it
successfully. I'm now looking into using a checkBoxCellEditor, but cannot
find any good examples. Do you have any?
Thanks
Jason

See:
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.ui.test s/Eclipse%20JFace%20Tests/org/eclipse/jface/tests/viewers/Ch eckboxTableViewerTest.java?rev=HEAD&content-type=text/vn d.viewcvs-markup
Also, ask about the CheckboxCellEditor on the eclipse.platform newsgroup.
It is a part of JFace and the owners of JFace primarily read that news
group:
