I maybe asking this incorrectly as I don't know what to look for. I have created a Form. I have a menu and you and can use the arrow keys to move up and down the list. Which works perfectly. However when a different Window is selected like your web browser. The arrow keys sill work to move around the menu. How can I make is so that the arrow keys only work when the Form Window has been clicked on is the Active Window.


Code:
if (isKeyPressed(VK_UP)) then
elseif (isKeyPressed(VK_DOWN)) then
end


Thanks!

it's beter to use the keydown event of the form

but you can use form.isForegroundWindow() for that

Alternatively you may use OnActivate and OnDeactivate methods.

Code:

local isFormActive = false;
form.OnActivate = function(sender)
   isFormActive = true; -- or use form.tag ...
end
form.OnDeactivate = function(sender)
   isFormActive = false;
end
