•
Java
Use the mouse in ImageView I don't know any method of drawing on, such as using canvas?
Solution
My coming here is a good solution to my problem isn't it?
AnchorPane anchorRoot;
double initX;
double initY;
ImageView iv = new ImageView(image);
final double maxX = iv.getImage().getWidth();
final double maxY = iv.getImage().getHeight();
anchorRoot.getChildren().add(iv);
iv.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent me) {
//System.out.println("Clicked,x:" + me.getSceneX() + " y:" + me.getSceneY());
//the event will be passed only to the circle which is on front
initX = me.getSceneX();
initY = me.getSceneY();
me.consume();
}
});
iv.setOnMouseDragged(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent me) {
//System.out.println("Dragged,x:" + me.getSceneX() + " y:" + me.getSceneY());
if (me.getSceneX() < maxX && me.getSceneY() < maxY) {
Line line = new Line(initX,initY,me.getSceneX(),me.getSceneY());
line.setFill(null);
line.setstroke(Color.RED);
line.setstrokeWidth(2);
anchorRoot.getChildren().add(line);
}
initX = me.getSceneX() > maxX ? maxX : me.getSceneX();
initY = me.getSceneY() > maxY ? maxY : me.getSceneY();
}
});
