FreSharp

Features

• Build Adobe Air Native Extensions using C#

Please see the feature rich example in https://github.com/tuarua/FreSharp/tree/master/example

The package is hosted on NuGet at https://www.nuget.org/packages/TuaRua.FreSharp/

How to use

Example - Convert a FREObject into a String, and String into FREObject

try {
   var airString = argv[0].AsString();
   Trace("String passed from AIR:" + airString);
}
catch (Exception e) {
  Console.WriteLine(@"caught in C#: type: {0} message: {1}", e.GetType(), e.Message);
}
const string sharpString = "I am a string from C#";
return sharpString.ToFREObject();

Example - Call a method on an FREObject

var person = argv[0];
var addition = person.Call("add", 100, 33);
Trace("result is: ", addition.AsInt());

Example - Get a property of a FREObject

var oldAge = person.GetProp("age").AsInt();
Trace("result is: ", oldAge);

Example - Convert a FREObject Object into a Dictionary

var dictionary = person.AsDictionary();
var name = dictionary["name"];

Example - Create a new FREObject

var newPerson = new FREObject().Init("com.tuarua.Person");
Trace("We created a new person. type =", newPerson.Type());

Native Stage - Adding native elements over the AIR window
The example includes AIRNativeANE for creating a child Window which can be used to contain WPF controls and graphics. In Windows 8.1+ the Window can be transparent. Buttons and images can be added easily from actionscript.

ANStage.init(stage, new Rectangle(100, 0, 400, 600), true, true);
ANStage.add();

var nativeButton = new ANButton(new TestButton(), new TestButtonHover());
nativeButton.addEventListener(MouseEvent.CLICK, onNativeClick);
var nativeSprite:ANSprite = new ANSprite();
nativeSprite.x = 150;

var nativeImage:ANImage = new ANImage(new TestImage());
ANStage.addChild(nativeSprite);
ANStage.addChild(nativeImage);
ANStage.addChild(nativeButton);

Advanced Example - Extending FreObjectSharp. Creating a C# version of flash.geom.point

using System.Collections;
using System.Windows;
using TuaRua.FreSharp;
using FREObject = System.IntPtr;

namespace FreSharp.Geom {
    public class FrePointSharp : FreObjectSharp {
        public FrePointSharp() { }
        public FrePointSharp(FREObject freObject) {
            RawValue = freObject;
        }
        public FrePointSharp(Point value) {
            uint resultPtr = 0;
            var args = new ArrayList {
                value.X,
                value.Y
            };

            RawValue = FreSharpHelper.Core.getFREObject("flash.geom.Point", FreSharpHelper.ArgsToArgv(args),
                FreSharpHelper.GetArgsC(args), ref resultPtr);
            var status = (FreResultSharp) resultPtr;

            if (status == FreResultSharp.Ok) {
                return;
            }
            FreSharpHelper.ThrowFreException(status, "cannot create point ", RawValue);
        }
        public void CopyFrom(FrePointSharp sourcePoint) {
            uint resultPtr = 0;
            var args = new ArrayList {
                sourcePoint.RawValue,
            };
            FreSharpHelper.Core.callMethod(RawValue, "copyFrom", FreSharpHelper.ArgsToArgv(args),
                FreSharpHelper.GetArgsC(args), ref resultPtr);
            var status = (FreResultSharp) resultPtr;
            if (status == FreResultSharp.Ok) {
                return;
            }
            FreSharpHelper.ThrowFreException(status, "cannot copyFrom ", FREObject.Zero);
        }
        public new Point Value => new Point(
            RawValue.GetProp("x").AsDouble(), 
            RawValue.GetProp("y").AsDouble());
    }
}
