= FME_INIT =
== Description ==
:The FME_INIT event is triggered before the FM dialog is displayed.
:To activate this event you need to use "{{((Dialog)): ((initevent))}}".
:You can use the previous value to check if the plug-in is executed for the first
:time in the host. In that case {{((previous))==((false))}}.

== Remarks: ==
:1) Using the instruction {{((setDialogEvent))(1)}} allows also to enable the FME_INIT event.
:However, it isn't recommended to use that by default, as it won't work  for the very first launch of the plug-in.
<code>

</code>
:2) For your convenience, this event is also triggered each time you recompile the code of your plug-in.

== Example ==
<code>
%ffp
Dialog: initevent

OnCtl(n): {
    if (e==FME_INIT) {
        if (!previous) Info("plug-in launched for first time");
        else Info("plug-in just launched or recompiled");
    }
    return false;
}
