Input numbers and add them up:

[Oso]

If you press Enter and the active gadget is #gad_number, or if you press the button (#gad-add) then you call AddNumber()

Thanks Mindphazer, I think the thing that confused me is that the below Select/Case, isn't specifically checking for the Enter key, but simply that #gad_number is tested as the active gadget for "whatever event" took place...

Code: Select all

  ev=WaitWindowEvent()
  If ev=#PB_Event_Menu
    Select GetActiveGadget()
      Case #gad_number,#gad_add : AddNumber()

Well, in fact, i don't really understand this :

Code: Select all

Case #gad_number, #gad_add : AddNumber()

In my opinion, this should be enough :

Code: Select all

Case #gad_number : AddNumber()

No need to check #gad_add as it's the button gadget and it's not attached to a menu

But maybe BarryG can explain this point ?

Yes, it seems to work fine with that amendment.

Code: Select all

Case #gad_number, #gad_add : AddNumber()

This is so you can press Enter on the "Add number" button. If you remove the "#gad_add" bit, then you can't press Enter on it to add a number. I wanted my example to be fully working with keyboard as well as mouse.

Yes, I see. There's quite a high attention to detail on this little example. It's good to find intentional keyboard support because reaching for the mouse is slow. Thanks for posting it Barry.

Thanks, Oso.
