= FME_KEYDOWN =

== Description ==

:FME_KEYDOWN event is triggered when the user presses a keyboard button.

:The n value of the events contains the VK code of the pressed key.

:To activate the FME_KEYDOWN event you need use "Dialog: keyevents" or setDialogEvent(4) in your code.

:If you want to check for mouse buttons, Shift, Ctrl, Alt etc. you need to use getAsyncKeyState() or getAsyncKeyStateF().

:This event is only triggered once per keypress; it is not triggered again if you hold the key.

== Example ==

<code>

%ffp

Dialog: keyevents

OnCtl(n): {

if (e == FME_KEYDOWN) {

Info("You just pressed key %d", n);

}

return false;

}

</code>

== Comments ==

:Everyone can add his comments about his experiences with this event here. Tips for using it are welcome, too.
