* Main.fx

package javafxapplication4;
import java.lang.System;
import javafx.ext.swing.SwingComponent;
import javafx.scene.input.MouseEvent;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.Scene;
import javafx.scene.shape.Line;
import javafx.stage.Stage;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
import javafx.scene.shape.Rectangle;
Stage {
    title: "Application title"
    var modelA:DefaultTableModel = new DefaultTableModel()on replace oldValue  {
        modelA.addColumn("aaa");
        modelA.addRow(["aaa1"]);
        modelA.addRow(["aaa2"]);
        modelA.addRow(["aaa3"]);
    var leftTable = SwingComponent.wrap(new JTable(modelA));
    var scene:Scene
    scene: scene = Scene {
            content: HBox {
                content: [
                leftTable,
                Line {
                        startX: 0,
                        startY: 0
                        endX: 0,
                        endY: leftTable.height
                        strokeWidth: 10
                        stroke: Color.BLACK;
                        onMouseDragged: function( e: MouseEvent ):Void {
                            System.out.println("e.x: {e.x}");
}when staring dragging from the rightmost area of the line to the left into the table it gives following output:
e.x: 2.0
e.x: 2.0
e.x: 1.0
e.x: 0.0
e.x: 0.0
e.x: -1.0
e.x: 2.147483568E9
e.x: -2.0
e.x: 2.147483568E9
e.x: -3.0
e.x: 2.147483568E9
e.x: -4.0
e.x: 2.147483568E9
e.x: -5.0
e.x: 2.147483568E9So, the question is where that e.x: 2.147483568E9 comes from? And how a coordinate (number of pixels?) can be floating?
Thanx!

Answer 1

The value 2.147483568E9 means 2.14... times 10 to 9th. Basically there's something evaluating to zero or being divided by zero to give you this value. It must be a bug in the event handling code. Could you file a bug report on it at javafx-jira.kenai.com?
thanks,
Josh
