boolean overlay

[shreya005]

As seen in figure, i have three options to choose from such that if i choose 1, the others will be unselected. each option is combination of a boolean button, boolean button overlay and round LED, such that if I click on either the LED or the corresponding boolean button, the LED is switched on. 

Now I don't know how to create the overlay (this program was developed by a previous user) for a 4th option of similar type which behaves in the same way. 

How do I do it?

You can customize a modern push button control such that the little triangle LED is a round LED and the housing is a rectangle.

Now put three or four of those inside a radiobutton container and you should be all set. No need for overlays of multiple controls or complicated code logic to deal with it.
