====== Application Development with MTASC / First Steps ====== 
\\ We begin with a simple example. A small app with a button. If you click on it an alert window will show up.\\
Steps: \\
===  1. Preparations === 
- make a new directory (e.g. hello_world) \\ 
- open the notepad and save the (yet empty file) file as helloworld.as in that directory
===  2. Getting the components in the library ===
- start the Flash IDE \\ 
- make a new flash (.fla) file \\ 
- drag a button and a alertbox from the "UI Components" on the stage, or make a double-click on the components \\ 
- when the components are in the library you can even delete it from the stage \\
- mark the only frame in the timeline, so that you see the action panel and add a class reference to the application logic \\

r = helloworld();

- compile the .fla into a flash movie (.swf) and close the IDE

===  3. Writing the App === 
Open the helloworld.as file into your texteditor and add the following code: 

    import mx.controls.Button;
            
    class helloworld {
            
        function helloworld(){
            var myBut:Button = _root.createClassObject(Button,"button2",5,{label:"Push me!"});
            myBut._x = 300;
            myBut._y = 100
            myBut.addEventListener("click", buttonclicked);
        }
            
        private function buttonclicked(event:Object):Void {
            mx.controls.Alert.show("hello world","title");
        }
    }
===  4. Compile the App ===
- open your text editor again for writing the compile.bat \\
- add the line:

    mtasc -cp "c:\program files\macromedia\flash mx 2004\en\First Run\Classes" -mx -swf helloworld.swf helloworld.as

- now open a command prompt on your working directory and type "build.bat"
- thats it!
