Make sure the enclosing NSScrollView isn't drawing it's background:
[textView enclosingScrollView] setDrawsBackground:NO];

Yes I am trying to draw it in a NSTextView. I tried what you
suggested but it did not work. I played with multiple combinations of:
[ textView setBackgroundColor:[ NSColor whiteColor ]/[ NSColor
clearColor ]];
[ textView setDrawsBackground:NO/YES ];
and switching the textView isOpaque to on and off.
I would look forward to any other suggestions.
Thanks

How are you drawing the text? If it's in a NSTextView you also need
to set the background colour of the view to clear, I believe, and
maybe you'll need to override the IsOpaque method to return NO.
(I'm not that sure of myself here but I seem to recall something
along these lines).

Dear All
I am trying to set the background colour of a range of text in
textview to a color with an alpha value less than 1.
I get the text storage and set its NSBackgroundColorAttributeName
attribute (through NSMutableAttributedString calls) to a colour
with an alpha value less than 1.
However when this background draws it draws the colour as solid
and as I decrease the alpha value( towards 0.0 ) the colour goes
towards black.
Any suggestions
Thanks
Fred
