Panel Viewer Update Editor
Update Editor allows you to view and modify a button's paramers
From the View menu, select Update Editor.
The Update Editor shows the current state of the blank button. Typically a blank button
will have 2 items: local variables and an initial configuration. These items can be modified
and more functions added such as templates, actions and events. With a blank template, there
will be no variables defined and the button will be set for the default clear button
state.
