Notifies handler(s) when a new form is created for the TScreen instance.
</short>
<descr>
<p>
<var>NewFormWasCreated</var> is method which notifies form handlers for the
<var>TScreen</var> instance when a new form instance is created. It calls the
NotifyScreenFormHandler method using the handler type for the notification and
the TCustomForm instance in <var>AForm</var> as arguments. The screen form
event is signalled for all registered handlers using the snNewFormCreated
screen notification type.
</p>
<p>
NewFormWasCreated is called at design-time from the source file manager in the
Lazarus IDE. It is called immediately after a new form instance is created and
added to the active project in the IDE. NewFormWasCreated is not called at
run-time in the LCL.
</p>
