Still no luck. When I switch off the background of the scrollview the
gray of the window in my test project comes through so it is clear all
backgrounds are not being drawn but the selection colour still behaves
in exactly the same way and draws in a solid colour.
Thanks

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
