Hmmm... then a simple question: how do I know if the status of the checkbox has changed?

The event comes to the OnGuiEvent(string value) function in the Internal_API file, where the user prescribes reactions to item changes.

At every tick, ask Peter's variable what state it is in. Although it may affect different sections of code If I need to know the state of 30 checkboxes for next operation, I need to spool a whole batch to execute what I can memorize anyway

Wrong. The event comes in the OnGuiEvent() function. There you receive and process it.

Fortunately, you're wrong)).
 
With a few hours to go, everything will be clear.

This is the colbec, but it is not clear why no event is generated for the standardOnChartEvent and what parameter is returned to the function as value?

Formally, we can call it a callback. If we consider the engine and the Expert Advisor as separate entities, despite the fact that they share memory of one program.

Value sends the value of the item parameter at the event of its change. That is, when you pressed the button - it returned "1". Pressed - you get "0". Typed text in the input field - you got the text in the case of the corresponding element. Clicked a checkbox - you got its name. Skipped a value - got its value.

The Value sends the value of the item parameter at the event of its change. In other words, if you press the button, it gets a "1". Pressed - got "0". Entered text in the input field - received text in the case of the corresponding item. Clicked a checkbox - you got its name. Skipped a value - we got it.

But this cannot be associated with the word cool - it can be associated with the word minimum.

And the coolest thing here could be the design, and I think the environment should be forgotten for now.

Formally all the programs work in shared memory, if you define it that way. Separate writing of code does not mean that the program is separate. It is through events that Windows communicates with all programs. Events are a common practice in message passing.

And how can you tell which element a value came from if only the value itself is transmitted?

The value is passed to the corresponding case of the function. The switch operator is there.

I got you. I will do the design as soon as the main tasks have been completed. I agree that it needs to be fine-tuned.
