Delphi: Frame and State of ActionList - Error?

Question

I have an Action List on a Form and a Frame (a unit of a Form is impelemented in the Frame).

I set Form2.General.State:=asSuspended in the Frame, and I have an error: Undeclared identifier: 'asSuspended'.

The code works normally in the Form, but not in the Frame.

Why?

Thanks!!!

What does "a unit of a Form is impelemented in the Frame" mean? — Andreas Rejbrand, Jul 06 '11 at 21:28
I suppose that `General` is a `TActionList` that is a part of your `TForm2`? — Andreas Rejbrand, Jul 06 '11 at 21:29
If I were you, I'd start learning basic Delphi (and OOP) programming terminology, such as `unit`, `class`, and `object` (=instance of class). — Andreas Rejbrand, Jul 06 '11 at 21:52

Add the unit in which asSuspended is defined to the uses clause of the frame unit.

It seems like you just have to add ActnList to the uses clause of the unit in which the error appears.

I told you to add `ActnList`, not `General`. – Andreas Rejbrand Jul 06 '11 at 21:41
The problem was that the compiler didn't know what `asSuspended` was. Therefore, you need to add `ActnList`, the unit in which `asSuspended` is defined. `General` is the *name* that *you* gave to a particular instance of a `TActionList` -- of course there is no *unit* called `General`! – Andreas Rejbrand Jul 06 '11 at 21:44

You should not add `General` to the uses list! There is no unit called `General`! You should add `ActnList` to the uses list, because `ActnList` is the unit in which `asSuspended` is defined! That is, do NOT write `uses General`. Instead, write `uses ActnList`. – Andreas Rejbrand Jul 06 '11 at 21:45
