I have a transparent window. Actually, translucent is probably more
accurate as it has an alpha value of around 0.5. I'm trying to figure out
how I can draw text on the window where the background of the text honors
the transparency of the window, but the text's foreground color is 100%
opaque (alhpa value of 1.0). I don't want the foreground color of the text
to use the alpha value of the window.
I've looked at both:
http://developer.apple.com/samplecode/Sample_Code/Cocoa/RoundTransparentWind
ow.htm
and:
http://www.bignerdranch.com/Resources/Examples.html
I've tried a number of things:
In the view's drawRect, I've done drawInRect on my string. This picks up
the opaque and alpha settings of the view. This actually makes sense to me.
I've also tried putting an NSTextField on my window, but that picks up the
opaque and alpha settings of its parent window as well.
I've spent some time reading a number of posts on the archive, but they all
seem to address this issues now covered by the RoundTransparentWindow
sample, or slight derivations of the transparent window problem.
Best regards,
Scot
