How to set a toolbar's button to inactive ?

Hi anyone,

My application has got a toolbar. I am able to do each button enable or not enable. This is the only way to do them active or inactive, i.e. when I do click over each one it does not anything. However if I do them not enable, I can not see the icons that they contain. I would like to do the same but showing the icons contained into the buttons. Do you know another way to do it without setting the ‘enable’ property to ‘off’?

Thanks a lot,

Cris
