Dragging Image in Javafx

Hello today I would like to write a blog of how can we make the image draggable in a Stage.
Firstly you need to know more about MouseEvent, ImageView in JavaFx API.

Here we’ll be working around the dragX , dragY properties of MouseEvent class and x, y properties of ImageView. I’ve seen so many blogs but none of the blog had given me the smooth dragging feature in javafx. So here I’m going to start my codes for smooth dragging ability to ImageView .

import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;
import javafx.scene.image.ImageView;
import javafx.scene.image.Image;
import javafx.scene.input.MouseEvent;

/**

 var myX:Number = 0;
 var myY:Number = 0;
 var tempX:Number = 0;
 var tempY:Number = 0;

def img:ImageView = bind ImageView {
                    x:bind tempX+myX
                    y:bind tempY+myY
                    image: Image {
                            backgroundLoading:true
                            url: "{__DIR__}everest.jpg"
                    }

                    onMouseReleased: function (e: MouseEvent): Void {
                            tempX = img.x;
                            tempY = img.y;
                            myX = 0;
                            myY = 0;
                    }

                    onMouseDragged: function (e: MouseEvent): Void {
                            myX = e.dragX;
                            myY = e.dragY;
                    }

            }
Stage {
    title: "ImageView Smoothly Dragging"
    scene: Scene {
        width: 450
        height: 400
        content: [
            img

        ]
    }
}

After using this code you can see the mouse dragging is being binded with the ImageView ‘x’ and ‘y’ position. Futher more for saving the temporary x and y position of ImageView I’ve used mouseReleased() event.

Thanks for viewing blog.
