About Events
These are a kind of message that RISC OS sends
to applications
to tell them what is happening. For example, when
a user clicks on
an icon, RISC OS sends a 'button click' event to
the application.
When a user moves a window, an 'open window' event
is sent to
the application.
In WimpBasic you connect a Procedure or Function
to these events.
WimpBasic will then automatically call your routine
when the event
is received.
