How can I know pressed mouse key on a GUI push button?

I have made a 'pushbutton' using GUI ('guide'). How can I know and display which mouse key (left, right or centre) I pressed over pushbutton?

Why would you need to know which mouse button is pressed over a pushbutton? Do you need to get different behavior depending on the mouse button pressed? If so, can't you use a pushbutton list?

No, actually I need this behaviour, else I will have to make 9 pushbuttons

See the figure's SelectionType property.

it is not a figure but a button on a figure created by 'guide'
