Spring Hibernate Communication between JavaFX and JavaScript inside WebView, using JSObject

The former articles demonstrate how to "Execute JavaScript in WebView from Java code" and "implement OnAlert EventHandler of WebEngine".

In order to call JavaFX from Javascript in WebView, we can create a JSObject in JavaFX, and then calling it's setMember() method to make it known to Javascript. After that, Javascript can call it's public methods and access it's public field.

Spring Hibernate Embed WebView in FXML, to load OpenLayers with OpenStreetMap.

Last article demonstrate how to "Embed OpenLayers with OpenStreetMap in JavaFX WebView". This article demonstrate how to do it in FXML.

Embed WebView in FXML, to load OpenLayers with OpenStreetMap.


New a JavaFX FXML Application in NetBeans.

Copy openstreetmap.html from last article.

Create MyBrowser.java, extends Region.
package javafxml_web;

import java.net.URL;
import javafx.scene.layout.HBox;
import javafx.scene.layout.Region;
import javafx.scene.web.WebEngine;
import javafx.scene.web.WebView;

        public MyBrowser(){

            getChildren().add(webView);
        
        }
}

Modify Sample.fxml to add MyBrowser, and remove un-used elements.

JavaFX 2.1 introduce a new StackedBarChart class. StackedBarChart is a variation of BarChart that plots bars indicating data values for a category. The bars can be vertical or horizontal depending on which axis is a category axis. The bar for each series is stacked on top of the previous series.

Spring Hibernate Embed OpenLayers with OpenStreetMap in JavaFX WebView

OpenLayers makes it easy to put a dynamic map in any web page. With OpenStreetMap, it's a free replacement of Google Maps. We can embed WebView loaded with OpenLayers in JavaFX to display map.

Embed OpenLayers with OpenStreetMap in JavaFX WebView


Create a HTML file, openstreetmap.html. Actually it's a normal web page HTML file.
<!DOCTYPE html>

    {});
     
   myMap.addLayer(wms);
 
   myMap.setCenter(new OpenLayers.LonLat(-122.349243, 47.651743));

Spring Framework Save WritableImage to file

To save WritableImage to file, e can use the code:


                    File file = new File("test.png");
                    RenderedImage renderedImage = SwingFXUtils.fromFXImage(writableImage, null);
                    ImageIO.write(
                            renderedImage, 
                            "png",
                            file);


Where we render the image by calling SwingFXUtils.fromFXImage() and write to file by calling ImageIO.write().

Complete example:

Modify the code in last post "Create and adjust Color using hue, saturation, brightness". Add a button to save the image once button clicked.

Spring Hibernate Define the range and space of NumberAxis in JavaFX charts

In the last post of StackedAreaChart, the month axis is displayed from 0~13. In order to specify the horizontal axis, we can use 3-parameters/4-parameters constructor of NumberAxis.

public NumberAxis(double lowerBound, double upperBound, double tickUnit)
Create a non-auto-ranging NumberAxis with the given upper bound, lower bound and tick unit.
Parameters:
  • lowerBound - The lower bound for this axis, ie min plottable value
  • upperBound - The upper bound for this axis, ie max plottable value
  • tickUnit - The tick unit, ie space between tickmarks

Example: 

package javafx21;

import javafx.application.Application;

import javafx.scene.chart.NumberAxis;
import javafx.scene.chart.StackedAreaChart;

Spring Hibernate JavaFX 2.1: javafx.scene.chart.StackedAreaChart

JavaFX 2.1 introduce a new StackedAreaChart class. StackedAreaChart is a variation of AreaChart that displays trends of the contribution of each value. (over time e.g.) The areas are stacked so that each series adjoins but does not overlap the preceding series. This contrasts with the Area chart where each series overlays the preceding series. The cumulative nature of the StackedAreaChart gives an idea of the total Y data value at any given point along the X axis. Since data points across multiple series may not be common, StackedAreaChart interpolates values along the line joining the data points whenever necessary.


In the example, some column in series 2 are missed. From the graph, it can be noticed how JavaFX display the StackedAreaChart with missed column.

<script>
var map;
function loadmap(){

  var options = {
      zoom: 16,
      center: new google.maps.LatLng(51.507222, -0.1275),
      mapTypeId: google.maps.MapTypeId.SATELLITE
  }
  map = new google.maps.Map(document.getElementById("mapcanvas"), options);
}
