なんとなくJavaFX

ふんわり表示するプログラムをJavaFXで何となく書いてみた。特に意味なし。

main.fx

package studyfx;

import javafx.animation.Interpolator;
import javafx.animation.Timeline;
import javafx.scene.image.Image;
import javafx.scene.image.ImageView;
import javafx.scene.input.MouseEvent;
import javafx.scene.paint.Color;
import javafx.scene.Scene;
import javafx.stage.Stage;
import javafx.stage.StageStyle;

var opacity = 0.0;

def image = Image {
   url: "{__DIR__}images/3415358870_1cc377423d_m.jpg"
}

var stage:Stage = Stage {
   title: "Application title"
   style: StageStyle.TRANSPARENT
   width: image.width
   height: image.height
   scene: Scene {
       fill: Color.TRANSPARENT
       content: ImageView {
           opacity: bind opacity
           preserveRatio: true
           image: image
           onMouseDragged: function(event:MouseEvent):Void {
               stage.x += event.dragX;
               stage.y += event.dragY;
           }
       }
   }
}

Timeline {
   keyFrames: [
       at (0s) { opacity => 0.0 },
       at (0.5s) { opacity => 1.0 tween Interpolator.EASEBOTH }
   ]
}.play();
