Details

The new color and, if specified, the display attribute apply to the entire text area if only the color and attr arguments are passed to the _setTextColor method. If you use area coordinates, only that portion of the text will be changed.

Example

This example makes a marked area red reverse:

   /* mark the area */
call notify('textview', '_get_mark_', 1,
             srow, scol, erow, ecol);
   /* assign red reverse to the area */
call notify('textview', '_set_text_color_',
            'red', 'reverse',
            srow, scol, erow, ecol);

This example colors all text blue:

call notify('textview', '_set_text_color_', 'blue');
