Add NOV Barcode 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 Barcode 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.Barcode.dll - assembly for the NBarcodeModule;
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 Barcode module
Open the Main.cs file and use the following code:
using System;
using Nevron.Nov;
using Nevron.Nov.Mac;
using Nevron.Nov.Barcode;
#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
NBarcodeModule.Instance
};
NNOVApplicationInstaller.Install(modules);
NSApplication.Main(args);
}
}
}
3. Create a Linear and Matrix (QR) Barcodes
Open the MainWindow.cs file and use the following code to create the Barcode:
using System;
using Nevron.Nov.Mac;
using Nevron.Nov.UI;
using Nevron.Nov;
using Nevron.Nov.Barcode;
using Nevron.Nov.Layout;
#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 stack panel
NStackPanel stackPanel = new NStackPanel();
stackPanel.Margins = new Nevron.Nov.Graphics.NMargins(5);
stackPanel.HorizontalPlacement = ENHorizontalPlacement.Left;
stackPanel.VerticalPlacement = ENVerticalPlacement.Top;
stackPanel.HorizontalSpacing = 5;
stackPanel.VerticalSpacing = 5;
// create linear barcode
NLinearBarcode barcode = new NLinearBarcode();
barcode.HorizontalPlacement = ENHorizontalPlacement.Center;
barcode.VerticalPlacement = ENVerticalPlacement.Center;
barcode.Text = "Nevron software";
barcode.PreferredHeight = 100;
barcode.Symbology = ENLinearBarcodeSymbology.Code128;
stackPanel.Add(barcode);
// create matrix barcode
NMatrixBarcode qrCode = new NMatrixBarcode();
qrCode.Symbology = ENMatrixBarcodeSymbology.QrCode;
stackPanel.Add(qrCode);
// create NOV host
this.ContentView = new NNovWidgetHost(stackPanel);
}
#endregion
}
}
Run the application - it should display a simple Mac window with a Linear and Matrix (QR) Barcodes.
