Work with buttons

The color devices have several modes of operations

where buttons of different kinds may be shown.

The library provides a ButtonEvent
that is raised when such a button is pressed with the pen.

The color of each button can be configured.
A button can be hidden and disabled.
A hidden button is invisible.

Clicks on a disabled button are ignored.

The library provides a function GetButtonConfig
for getting a button bar object that contains the button configurations

of the connected device.

A button bar is tied to a certain mode of operation that has buttons.

The button configuration collection inside the button bar may be modified.

Pass the changed button bar object  to SetButtonConfig
