NinjaScript > Language Reference > Add On > IWorkspacePersistence Interface

When creating your NTWindow, be sure to implement the IWorkspacePersistence interface as well for the ability to save and restore your window with NinjaTrader workspaces.

Note: AddOn Classes which derive from NTWindow or implements IWorkspacePersistance CANNOT be a nested type of another class and MUST have a default constructor

This interface contains two methods and one property which must be hidden by the implementing class:

Restore()	Restores the window from workspaces.
Save()	Saves the window to workspaces.
WorkspaceOptions	Sets required workspace options.

Examples


public class MyWindow : NTWindow, IWorkspacePersistence { // default constructor public MyWindow() { // Define our NTWindow. If we want to use NT style tabs, we would define that here. // WorkspaceOptions property must be set Loaded += (o, e) => { if (WorkspaceOptions == null) WorkspaceOptions = new WorkspaceOptions("MyWindow-" + Guid.NewGuid().ToString("N"), this); }; } // IWorkspacePersistence member. Required for restoring window from workspaces public void Restore(XDocument document, XElement) { if (MainTabControl != null) MainTabControl.RestoreFromXElement(element); } // IWorkspacePersistence member. Required for saving window to workspaces public void Save(XDocument document, XElement element) { if (MainTabControl != null) MainTabControl.SaveToXElement(element); } // IWorkspacePersistence member public WorkspaceOptions WorkspaceOptions { get; set; } }

public class MyWindow : NTWindow, IWorkspacePersistence

{

// default constructor

public MyWindow()

{

// Define our NTWindow. If we want to use NT style tabs, we would define that here.

// WorkspaceOptions property must be set

Loaded += (o, e) =>

{

if (WorkspaceOptions == null)

WorkspaceOptions = new WorkspaceOptions("MyWindow-" + Guid.NewGuid().ToString("N"), this);

};

}

// IWorkspacePersistence member. Required for restoring window from workspaces

public void Restore(XDocument document, XElement)

{

if (MainTabControl != null)

MainTabControl.RestoreFromXElement(element);

}

// IWorkspacePersistence member. Required for saving window to workspaces

public void Save(XDocument document, XElement element)

{

if (MainTabControl != null)

MainTabControl.SaveToXElement(element);

}

// IWorkspacePersistence member

public WorkspaceOptions WorkspaceOptions { get; set; }

}
