How to disable a cell in TableViewer [message #437569]

Originally posted by: gtoor.pervasive.com

I am using the a TableViewer and want to disable cells within
the table. I would like to set the background color to let the
user know the cell is not editable. I have implemented
ICellModifier.canModify() but don't really like the implementation since it
gives no visual cues as to which cells cannot be modified. And
unfortunately, TableItem.setBackground() sets the background color of the
entire row.

thanks in advance.

Try TableItem.setBackground (int index, Color color):

/**
* Sets the background color at the given column index in the receiver
* to the color specified by the argument, or to the default system color for
the item
* if the argument is null.
*
* @param index the column index
* @param color the new color (or null)
*
* @exception IllegalArgumentException <ul>
* <li>ERROR_INVALID_ARGUMENT - if the argument has been disposed</li>
* </ul>
* @exception SWTException <ul>
* <li>ERROR_WIDGET_DISPOSED - if the receiver has been disposed</li>
* <li>ERROR_THREAD_INVALID_ACCESS - if not called from the thread that
created the receiver</li>
* </ul>
*
* @since 3.0
*

public void setBackground (int index, Color color)
