### Description

The toggle button is a push button that needs to be clicked once to toggle on, and one more time to toggle off. The `Fl_Toggle_Button` subclass displays the "on" state by drawing a pushed-in button.

Buttons generate callbacks when they are clicked by the user. You control exactly when and how by changing the values for `type()` and `when()`.
