The Button and how to create it

The button inherits from the control class. It is one of the many ways for an application to recieve input. A button is verry common in
GUI applications as a way to get input from a user. When a button is clicked, a callback function is called.


            --Button:

            f1 = form(10, 10, 100, 100, false, "Main", color.white, color.AirForceBlue, true, false, false, false, false, false, true)

            mybutton = button("MB", 1, 1, action, color.black, color.buttoncontrol, f1)

The code is exactly how you would create a button. You must have a form created in order to store you button, as with any other derivative of
the control class. As always you can declare any class two ways and if you dont remember how, read the forms reference here: Forms
The image below shows what the button declared above looks like.
