This event will occur when a box is checked or cleared.
Appropriate code for this event includes any processing that needs to be done when an option is enabled or disabled. In particular the "activation" (or deactivation or graying out of other entities in the window, that depend on the current box being "checked" is expected to be in the action logic for this type of event.
In MWAPI, these events are called "SELECT" and "DESELECT".
The high level event Check occurs after the low level events select and deselect for a Check Box component.
Note: The event Check is triggered both after a deselect and after a select event. In general, it is easier to attach event-handling code to either of these low-level events, than to the high level event Check.
