Simple Demo that shows how Elements can effect other elements in the Window

In this case, the slider controls the size of the text font and the value shown in the spinner
|
|
Additionally, if the spinner is changed, the text size is changed and so is the slider
|
|
In other words, the slider and the spinner are essentially connected together
