Two simple JavaFX code handling onMouseDragged event.

import javafx.ui.*;
import javafx.ui.canvas.*;

Canvas {
    content: Circle {
        var x = 50
        var y = 50
        transform: bind translate(x, y)
        radius: 30
        fill: red
        onMouseDragged: operation(e) {
                x += e.localDragTranslation.x;
                y += e.localDragTranslation.y;

        }
    }
}

                y += e.localDragTranslation.y;
            }
            if (e.button == 3) {
                radius += e.localDragTranslation.x;
            }
        }
    }
}

        var y = 50

        var color = red:Color
        transform: bind translate(x, y)

        fill: bind color
        onMouseDragged: operation(e) {

            }
            if (e.button == 3) {
                radius += e.localDragTranslation.x;
            }
        }
        onMousePressed: operation(e){
            color = Color {blue: 0.0, green: 0.0, red: 1.0, opacity: 0.5};
        }
        onMouseReleased: operation(e){
            color = red:Color;
        }
    }]
}
