Hi Mark,

You haven't mentioned anything about the isTeplate property yet, so
maybe you aren't aware of it.

Take a look at the section of the AppKit Leopard release notes titled
"Text and image effects: -[NSImage isTemplate]".

Hello,

I have been trying to get automatic image highlighting to work in
"rounded textured" style buttons, created in IB. So far I am able to
make this work just fine when using "system provided" images (for
example "NSGoRightTemplate") but unable to make this work with my own
images provided as either PNG or icns.

Just to be clear what I am referring to here, I mean the highlighting that occurs on "push on push off" or "toggle" style buttons. For "push on push off", the image is (or should be) highlighted in white on the dark gray background for NSOnState, and for toggle style the NSOnState
highlight is blue. I've followed the advice in the HIG and just
specified an image for the button and no "alt. image". And if I use
NSGoRightTemplate all is well, with my images not so much.

So it seems to me there must be some additional pre-requisites for the
button images that I've missed - can anyone advise? My images do
already have an alpha mask, and like I say I have tried PNG and ICNS
format so far.

Cheers

..Mark..
