Thanks for the reply, but unfortunately it doesn't answer my question. I found these properties days ago but am still unable to make the icon's background transparent.
A normal button is easy enough, with the transparency colour option available, bit this doesn't seem to be present amongst the navigator check button's options.
I want to leave the button the colour it is and add an icon to it - which i did. The icon has a white background, which i don't want to show. How do i get rid of the white?
Is it actually possible?
