The interface member can not be implemented

[Stanfillirenfro]

Hello!

I am trying to implement my own add window.
The documentation has guided me to the following code:

public class AddOnFrameworkWindow : NTWindow, IWorkspacePersistence
    {
        public AddOnFrameworkWindow()
        {
            TabControl tc = new TabControl();

            TabControlManager.SetIsMovable(tc, true);
            TabControlManager.SetCanAddTabs(tc, true);
            TabControlManager.SetCanRemoveTabs(tc, true);

            TabControlManager.SetFactory(tc, new AddOnFrameworkWindowFactory());

            Content = tc;
        }
    }​

But when I compile the code, I have the following error message:

'NinjaTrader.NinjaScript.Indicators.AddOnFramework Window' does not implement the interface member 'NinjaTrader.Gui.Tools.IWorkspacePersistence.Resto re(System.Xml.Linq.XDocument, System.Xml.Linq.XElement)'.

Is there any specific using declaration to be added except those in the "#region Using declarations" list when we create a new indicator?
Could someone please points out where I am mistaking?

I would appreciate any help.

Best regards,

Hello Stanfillirenfro,

Thank you for your post.

You also need to add the Restore() and Save() methods which are required for restoring the window from a workspace and saving the window to a workspace. The following page has a section "Setting Up Workspace Persistence" that covers this information:

Please let us know if we may be of further assistance.

Many thanks NinjaTrader_Emily for your help.

Now I am receiving another error message such as: XElement, XDocument can not be found. Are these specific "includes"?
Could you please advise me how to fix this problem?

Many thanks in advance.

I compared the AddOnFramework script with a fresh AddOn script created via the NinjaScript Wizard. It appears that the new script does not have the following using statement that includes the XElement and XDocument information needed:

using System.Xml.Linq;​

Please add this to the Using Declarations region at the top of your script and it should resolve the compile errors.

Thank you for your time and patience.

Thank again NinjaTrader_Emily for your help.

I think I need other using statements. TabControl in

TabControl tc = new TabControl();

and AddOnFrameworkWindowFactory in

TabControlManager.SetFactory(tc, new AddOnFrameworkWindowFactory());

can not be found.

I would really appreciate your help to find this statements.

Many thanks in advance.

Hello Stanfillirenfro,

Thank you for your reply.

TabControl is associated with this using statement:
using System.Windows.Controls;

TabControlManager is associated with this using statement:
using NinjaTrader.Gui.Tools;

I was able to get this information from the "AddOn Framework NinjaScript Basic" file found on this page:

https://ninjatrader.com/support/helpGuides/nt8/addon_development_overview.htm

I hovered my mouse over TabControl to see the class it is part of and did the same for TabControlManager. You may even be able to just compare your script's using declarations with those from the sample and copy whichever ones you are missing.

Thank you for your time and patience.

Many thanks NinjaTrader_Emily for your valuable help.

Sorry to disturb you again, but I am just failing to find the using statement of

AddOnFrameworkWindowFactory()

.
The error message is as followed:

The namespace AddOnFrameworkWindowFactory can not be found.

I have downloaded the file you have attached above and uploaded it. Only three of using statements were missing.

Since the AddOnFrameworkWindowFactory() is a function, by hovering the mouse over it, the corresponding class can not been puped up.

I would appreciate your help.

Thanks in advance.

Hello Stanfillirenfro,

The AddOnFrameworkWindowFactory class is a custom class that is explained on this page in the help guide:
