identifier AttachToAllItems is undefined

Hey all,

[AC24, VS 2017]

I am stumped on this.  I have successfully used dialogs in other Add_Ons.  I am using a working, previous project as a go-by for this new one.  Maybe that's my problem, but it is not clear to me how slight differences would impact.

So far, I have created a blank dialog with only an 'OK' button to test my proof of concept.  It will eventually be employed to alert the users if they should open a .bpn file.

in the .grc file

#include "JHP_AutoLoadResIDs.hpp"

'GDLG' 32500  Modal	0	0  1000  1000	"JHP:  ERROR - Do not open .bpn file" {
/* [  1] */ Button	400  300   70   43		LargePlain	"OK"
}

'DLGH'  32500  DLG_32500_JHP_AUTOLOAD {
1	"JHP_OK"	Button_0
}

in the .hpp file

#pragma once

#ifndef JHP_AUTOLOAD_DIALOG_HPP
#define JHP_AUTOLOAD_DIALOG_HPP

#include	"DGModule.hpp"

class JHP_AutoLoad_Dialog :	public DG::ModalDialog,
				public DG::ButtonItemObserver
{
protected:
	enum Controls {
		OkID = 1
	};

	DG::Button OK_Button;
	virtual void ButtonClicked(const DG::ButtonClickEvent& ev) override;
public:
	JHP_AutoLoad_Dialog();
	~JHP_AutoLoad_Dialog();
};

#endif JHP_AUTOLOAD_DIALOG_HPP

in the .cpp file

JHP_AutoLoad_Dialog::JHP_AutoLoad_Dialog() :
	DG::ModalDialog(ACAPI_GetOwnResModule(), 32500, ACAPI_GetOwnResModule()),
	OK_Button(GetReference(), OkID)
{
	AttachToAllItems(*this);
}

JHP_AutoLoad_Dialog::~JHP_AutoLoad_Dialog()
{
}

void JHP_AutoLoad_Dialog::ButtonClicked(const DG::ButtonClickEvent& ev)
{
	if (ev.GetSource() == &OK_Button)
	{
		PostCloseRequest(Cancel);
	}
}

It is here where the problem is

I have tried to remedy this by:
- - making sure of necessary #include directives

- - rearranging chunks of code to influence definition

The main difference I see between this failed AttachToAllItems and the one that works in my go-by is that this Add-On does not provide a menu selection.  It only establishes

err = ACAPI_Notify_CatchProjectEvent(APINotify_Open, JHP_EventHandler);

in

// -----------------------------------------------------------------------------
// Initialize
//		called after the Add-On has been loaded into memory
// -----------------------------------------------------------------------------

GSErrCode __ACENV_CALL	Initialize (void)

This strategy of organization is working with calls to a typical ACAPI_WriteReport("message", true);

Could this placement of ACAPI_Notify_CatchProjectEvent in __ACENV_CALL Initialize be the cause?
Am I missing an #include?

New laptop - Am I missing something in my VS install/configuration?

Have I provided enough detail?

Thanks to all that look and many thanks to all that answer,

Chris

To be able to  use AttachToAllItems function your  class needs  to inherit from  DG::CompoundItemObserver

Brilliant!  Thanks for the response that was right on target.
