Add NOV Diagram control in MonoMac project at runtime
To get started and host NOV in your Mac OS X (MonoMac) application, take a look at:
Getting Started with NOV in MonoMac project
The following topic shows how to add a NOV Diagram Widget (control) in MonoMac project at runtime.
1. Reference the NOV Assemblies
Ensure that your application references the following NOV dlls:
Nevron.Nov.Presentation.dll - core NOV portable assembly;
Nevron.Nov.Host.MonoMac.dll - presentation host for MonoMac;
MonoMac.dll - make sure to reference the MonoMac.dll that comes with the NOV installation and remove the default one, which is created by Xamarin Studio;
Nevron.Nov.Diagram.dll - assembly for the NDiagramModule;
You can reference the dlls directly from the System/Applications/NevronOpenVision.MonoMac.app/Contents/Bin folder or copy those dlls to a folder which is more convenient for referencing.
2. When initializing the NOV Application, make sure to create the Diagram module
Open the Main.cs file and use the following code:
using System;
using Nevron.Nov;
using Nevron.Nov.Mac;
using Nevron.Nov.Diagram;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
class MainClass
{
static void Main(string[] args)
{
NSApplication.Init();
NLicenseManager.Instance.SetLicense(new NLicense("LICENSE KEY"));
// install NOV
NModule[] modules = new NModule[]
{
// TODO: Create modules here
NDiagramModule.Instance
};
NNOVApplicationInstaller.Install(modules);
NSApplication.Main(args);
}
}
}
3. Create the Diagram Drawing View, add two shapes and connect them
Open the MainWindow.cs file and use the following code to create the Diagram:
using Nevron.Nov;
using Nevron.Nov.Diagram;
using Nevron.Nov.Diagram.Shapes;
#if UNIFIEDAPI
using Foundation;
using AppKit;
#else
using MonoMac.Foundation;
using MonoMac.AppKit;
#endif
namespace MonoMacApplication1
{
public partial class MainWindow : NSWindow
{
#region Constructors
// Called when created from unmanaged code
public MainWindow(IntPtr handle)
: base(handle)
{
Initialize();
}
// Called when created directly from a XIB file
[Export("initWithCoder:")]
public MainWindow(NSCoder coder)
: base(coder)
{
Initialize();
}
// Shared initialization code
void Initialize()
{
NApplication.ApplyTheme(new NMacElCapitanTheme());
// Create a drawing view
NDrawingView drawingView = new NDrawingView();
// Get the drawing view document and its active page
NDrawingDocument document = drawingView.Document;
NPage activePage = document.Content.ActivePage;
// Create a rectange shape to the active page items
NBasicShapesFactory factory = new NBasicShapesFactory();
NShape rectangleShape = factory.CreateShape(ENBasicShapes.Rectangle);
rectangleShape.Text = "My First Shape";
rectangleShape.SetBounds(25, 25, 100, 100);
activePage.Items.Add(rectangleShape);
// Create a rect with corner rounding
NShape roundRectShape = factory.CreateShape(ENBasicShapes.Rectangle);
roundRectShape.Text = "My Rounded Rect Shape";
roundRectShape.Geometry.CornerRounding = 10;
roundRectShape.SetBounds(400, 80, 100, 100);
activePage.Items.Add(roundRectShape);
// Create a rounded routable connector
NConnectorShapesFactory connectorFactory = new NConnectorShapesFactory();
NShape connector = connectorFactory.CreateShape(ENConnectorShapes.RoutableConnector);
connector.Geometry.CornerRounding = 20;
connector.GlueBeginToShape(rectangleShape);
connector.GlueEndToShape(roundRectShape);
activePage.Items.Add(connector);
// create NOV host
this.ContentView = new NNovWidgetHost(drawingView);
}
#endregion
}
}
Run the application - it should display a simple Mac window with a Diagram.
