Controls

You can create controls via the GemGui static factory class

   var button = GemGui.Button(int x, int y, int sizeX, int sizeY);

Available Controls

   Button(int x, int y, int sizeX, int sizeY)
   ImageButton(Texture2D image, int x, int y, int sizeX, int sizeY)
   Label(Spritefont font, int x, int y, int sizeX, int sizeY, string text)
   TextField(int x,int y,int sizeX, int sizeY)

Each control has the following fields and methods which are described bellow

  ViewEvents Events
  RenderStyle Style
  ControlOptions Options

  //the current control and the elapsed time
  void Transform(Action<AControl,double> transformation) 
  void AddTransformation(ITransformation transformation)
  vod SetFocus()

Predefined Styles

  myButton.Style = StyleFactory.ButtonDefault;

Add a custom style

 StyleFactory.Add("CustomStyle", 
                  new RenderStyleParameters(),

                  (element,style)=> {
                      element.GotFocus +=
                      (element,args) => style.Transparency = 1.0f;
                      element.LostFocus += 
                      (element,args) => style.Transparency = 0.5f;
                  });
 myButton.Style = StyleFactory["CustomStyle"];

##Example

var myLabel = GemGui.Label(font: FontContainer["Segoe_10"],
                           x: 10,
                           y: 10,
                           sizeX: 100,
                           sizeY: 30,
                           text: "Hello");
myLabel.VerticalAlignment = VerticalAlignment.Center;

var myButton = GemGui.Button(x: 10,
                             y: 50,
                             sizeX: 50,
                             sizeY: 50);

myButton.FluentBuild
        .Style(StyleFactory.ButtonDefault)
        .Text("Click me")
        .TextColor(Color.Red)
        .BackgroundColor(Color.White)
        .OnClick((element,args) => Log.Info("i clicked my button"));

var group = GemGui.Groups.GridLayout;
group.Assign(myLabel,myButton);
