Two buttons or not two buttons That is the question

The DJ is happy with the program so far. However, he thinks it would work better if he had just one button instead of two. He's convinced this would be easier to use, because he wouldn't have to move his mouse around the screen quite so much.

ov stop whaW this bu-tU> does?

It is possible to use a single button here but, without changing the physical appearance of the button each time it's clicked, a user can't possibly know what state the button is currently in, even though the DJ does have ears in this instance. But, in general, using a button to switch between two states is not regarded as best practice in GUI design.

What your DJ friend actually wants is some sort of visual toggle... something that can be flipped between one of two states: on/off, open/close, flip/flop, and so on. You need to use a different graphical interface element.

Is there a GUI visual toggle you can use here?

Take a look at the following window that appears when you ask a full-featured web browser to display its preferences. Grab a pencil and draw a circle around any graphical interface elements you haven't worked with yet.

From the elements that you have circled, identify one that might be of use to you in your program. Which would work best as an on/off toggle? Write your answer here.
