GMapsFX 2.12.0 Released – Mac OSX Garbled Text Fixed!

May 8, 2017 / rterp / Leave a comment

The latest version of GMapsFX has been released and includes a major bug fix and a few enhancements.

Bug Fix

Last month I reported a bug that has been affecting users of GMapsFX on Mac OSX where the text appeared ‘garbled’. An example image is below.

The underlying issue is that the JavaFx WebView component on Mac OSX is rendering icons rather than letters for some websites, including Google Maps.

I receive a tweet from @ggeorgopoulos1 with a proposed work around that involves injecting CSS programatically into the page with the correct font. I’ve incorporated the code into the latest GMapsFX library and I am happy to say that it is working once again on Mac OSX!

Enhancements

Added a setKey() method to the GoogleMap compoment

This will allow a key to be set in the FXML and will eliminate the need to programatically set a key on the map object at runtime.

Support for Clustered Markers

Added ability to cluster markers by utilizing the Google Maps Marker Clustering API. https://developers.google.com/maps/documentation/javascript/marker-clustering

clusteredMarkers

Ability to Set Route Colors

Route colors can now be specified rather than having to rely on the default blue that Google Maps uses.

Garbled Text in GMapsFX on Mac OSX

March 29, 2017 / rterp / Leave a comment

I have been receiving a lot of messages the last couple of months regarding the text in GMapsFX applications looking “garbled”, as illustrated in the screenshot below.

This is appears to only affect applications running on Mac OSX. GMapsFX makes use of the JavaFX WebView component under the hood, so I created a simple test app that loads Google Maps into a WebView to confirm the issue was the WebView component.

I filed a bug report with Oracle, but apparently this is a known issue that affects only some websites in WebView on Mac. Linux and Windows applications using the WebView component are unaffected.

http://bugs.java.com/bugdatabase/view_bug.do?bug_id=JDK-8088205

The issue has been open for a couple of years now which leads me to think that a recent Mac update may be contributing to the problem becoming more widespread.

Unfortunately a fix for this won’t be available until Java 9, and there is no work around that I know of.

Why You Shouldn’t Use Complex Objects as HashMap Keys

February 13, 2017February 10, 2017 / rterp / 2 Comments

I’m a big believer in learning from my mistakes, but I’m an even bigger believer in learning from other people’s mistakes. Hopefully someone else will be able to learn from my mistakes.

mistakes

This post is inspired by an issue that took me a number of days to track down and pin point the root cause. It started with NullPointerExceptions randomly be thrown in one of my applications. I wasn’t able to consistently replicate the issue, so I added an indiscriminate amount of logging to the code to see if I could track down what was going on.

What I found was that when I was attempting to pull a value out of a particular hashmap, the value would sometimes be Null, which was a bit puzzling because after initializing the map with the keys/values, there were no more calls to put(), only calls to get(), so there should have been no opportunity to put a null value in the map.

Below is a code snippet similar (but far more concise) to the one I had been working on.

	public void runTest() {
	ProductSummaryBean summaryBean = new ProductSummaryBean(19.95, "MyWidget", "Z332332", new DecimalFormat("$#,###,##0.00"));
	ProductDetailsBean detailBean = getProductDetailsBean(summaryBean);

	productMap.put(summaryBean, detailBean);

	//Load the same summaryBean from the DB
	summaryBean = loadSummaryBean("Z332332");

	//Pull the detailBean from the map for the given summaryBean
	detailBean = productMap.get(summaryBean);

	System.out.println("DetailBean is: " + detailBean );
	}

There is a ProductSummaryBean with a short summary of the product, and a ProductDetailBean with further product details. The summary bean is below and contains four properties.

	package com.lynden.mapdemo;

	import java.text.DecimalFormat;
	import java.util.Objects;

	public class ProductSummaryBean {

	protected double price;
	protected String name;
	protected String upcCode;
	protected DecimalFormat priceFormatter;

	public ProductSummaryBean(double price, String name, String upcCode, DecimalFormat priceFormatter) {
	this.price = price;
	this.name = name;
	this.upcCode = upcCode;
	this.priceFormatter = priceFormatter;
	}

	public double getPrice() {
	return price;
	}

	public String getName() {
	return name;
	}

	public String getUpcCode() {
	return upcCode;
	}

	public DecimalFormat getPriceFormatter() {
	return priceFormatter;
	}

	@Override
	public int hashCode() {
	int hash = 7;
	hash = 79 * hash + (int) (Double.doubleToLongBits(this.price) ^ (Double.doubleToLongBits(this.price) >>> 32));
	hash = 79 * hash + Objects.hashCode(this.name);
	hash = 79 * hash + Objects.hashCode(this.upcCode);
	hash = 79 * hash + Objects.hashCode(this.priceFormatter);
	return hash;
	}

	@Override
	public boolean equals(Object obj) {
	if (this == obj) {
	return true;
	}
	if (obj == null) {
	return false;
	}
	if (getClass() != obj.getClass()) {
	return false;
	}
	final ProductSummaryBean other = (ProductSummaryBean) obj;
	if (Double.doubleToLongBits(this.price) != Double.doubleToLongBits(other.price)) {
	return false;
	}
	if (!Objects.equals(this.name, other.name)) {
	return false;
	}
	if (!Objects.equals(this.upcCode, other.upcCode)) {
	return false;
	}
	if (!Objects.equals(this.priceFormatter, other.priceFormatter)) {
	return false;

	return true;

	return "ProductBean{" + "price=" + price + ", name=" + name + ", upcCode=" + upcCode + ", priceFormatter=" + priceFormatter + '}';
	}

Any guesses what happens when the code above is run?

Exception in thread "main" java.lang.NullPointerException
 at com.lynden.mapdemo.TestClass.runTest(TestClass.java:34)
 at com.lynden.mapdemo.TestClass.main(TestClass.java:50)

So what happened? The HashMap stores its keys by using the hashcode of the key objects. If we print out the hashcode when the ProductSummaryBean is first created and also after its read out of the DB we get the following.

SummaryBean hashcode before: -298224643
SummaryBean hashcode after: -298224679

We can see that the hashcode before and after are different, so there must be something different about the two objects.

SummaryBean before: ProductBean{priceFormatter=java.text.DecimalFormat@67500, price=19.95, name=MyWidget, upcCode=Z332332}
SummaryBean after: ProductBean{priceFormatter=java.text.DecimalFormat@674dc, price=19.95, name=MyWidget, upcCode=Z332332}

Printing out the entire objects shows that while name, upc code, and price are all the same, the DecimalFormatter used for the price is different. Since the DecimalFormatter is part of the hashcode() calculation for the ProductSummaryBean, the hashcodes between the before and after versions of the bean turned out different. Since the hashcode was modified, the map was not able to find the corresponding ProductDetailBean which in turned caused the NullPointerException.

Now one may ask, should the DecimalFormat object in the bean been used as part of the equals() and hashcode() calculations? In this case, probably not, but this may not be true in your case. The safer way to go for the hashmap key would be to have used the product’s upc code as the HashMap key to avoid the danger of the keys changing unexpectedly.

How to Import the GMapsFX Component into SceneBuilder

October 3, 2016September 30, 2016 / rterp / Leave a comment

I recently received a question regarding how to add the GMapsFX component to SceneBuilder, so it could be dragged and dropped onto the UI as its being constructed.

I thought I would address the question here since the good folks at Gluon have made it extremely easy to import custom components to SceneBuilder.

The first step is to click the small ‘gear’ icon just to the right of the Library search box and select the “JAR/FXML Manager” menu item from the popup menu.

screen-shot-2016-09-30-at-2-49-38-pm

Since the GMapsFX binaries are in the Maven Central repository SceneBuilder can directly download and install the component from there. Click the “Search repository” link in the Library Manager dialog box.

screen-shot-2016-09-30-at-2-52-03-pm

Next, enter “GMapsFX” into the Group or artifact ID text box, and click the “Search” button. You should get a search result with the com.lynden:GMapsFX artifact. Select the result and click “Add JAR”.

screen-shot-2016-09-30-at-2-52-24-pm

The GoogleMapView should be the only component available in the Jar file, select it and click the “Import Component” button.

screen-shot-2016-09-30-at-2-52-33-pm

Finally, you should get a confirmation that the library was imported into SceneBuilder.

screen-shot-2016-09-30-at-2-52-41-pm

At this point the GoogleMapView component should be visible in the “Custom” component section of the pallette, and ready to be dragged and dropped onto your UI. Due to the way the component is constructed, a map will not display in SceneBuilder or the SceneBuilder preview tool, but the proper FXML will be generated and the map will display when the program is run.

Mapping Directions with JavaFX using the GMapsFX Directions API

August 22, 2016August 19, 2016 / rterp / 2 Comments

Mapping directions in a JavaFX application is easy with the Directions API that was recently introduced in GMapsFX. In this blog post I’ll walk through an example of setting up an application with a map and a couple of text fields, one which will be used for the trip origin and the second which will be used for the trip destination. When the user hits ‘Enter’ in the destination text field, the map will display the directions.

Starting off with the FXML file, we have an AnchorPane which contains the GoogleMapView and 2 TextFields. The AnchorPane has a controller assigned to it named FXMLController, and both components have an FX ID associated with them so they will be accessible from the FXMLController class. Also, the destination TextField has an action, “toTextFieldAction” associated with it, so this method will be called when the user hits the ‘Enter’ key in the TextField.

	<?xml version="1.0" encoding="UTF-8"?>

	<?import com.lynden.gmapsfx.GoogleMapView?>
	<?import javafx.scene.control.TextField?>
	<?import javafx.scene.layout.AnchorPane?>

	<AnchorPane id="AnchorPane" prefHeight="443.0" prefWidth="711.0" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/8.0.65" fx:controller="com.lynden.gmaps.directions.FXMLController">
	<children>
	<GoogleMapView fx:id="mapView" layoutX="-311.0" layoutY="-244.0" prefWidth="490.0" AnchorPane.bottomAnchor="0.0" AnchorPane.leftAnchor="0.0" AnchorPane.rightAnchor="0.0" AnchorPane.topAnchor="0.0" />
	<TextField fx:id="fromTextField" prefHeight="27.0" prefWidth="222.0" promptText="From:" AnchorPane.leftAnchor="10.0" AnchorPane.topAnchor="10.0" />
	<TextField fx:id="toTextField" layoutX="10.0" layoutY="10.0" onAction="#toTextFieldAction" prefHeight="27.0" prefWidth="222.0" promptText="To:" AnchorPane.leftAnchor="10.0" AnchorPane.topAnchor="50.0" />
	</children>
	</AnchorPane>

The result should look as follows:

Next, I’ve cut up the relevant parts of the FXMLController class. The MapComponentInitializedListener interface needs to be implemented by the controller since the underlying GoogleMap doesn’t get initialized immediately. The DirectionsServiceCallback interface also needs to be implemented, although in this example I won’t be doing anything with it.

The GoogleMapView and the TextFields components from the FXML file are defined below and annotated with @FXML.

There is also a reference to the Directions Service as well as StringProperties to represent the ‘to’ and ‘from’ endpoints that the user will enter.

	public class FXMLController implements Initializable, MapComponentInitializedListener, DirectionsServiceCallback {

	protected StringProperty from = new SimpleStringProperty();
	protected StringProperty to = new SimpleStringProperty();

	@FXML
	protected GoogleMapView mapView;

	@FXML
	protected TextField fromTextField;

	@FXML
	protected TextField toTextField;

FXMLController.java

After the controller is created, its initialize method is called which will set the MapView’s initialization listener to the FXMLController as well as bind the ‘to’ and ‘from’ String properties to the TextProperties of their respective TextFields.

	@Override
	public void initialize(URL url, ResourceBundle rb) {
	mapView.addMapInializedListener(this);
	to.bindBidirectional(toTextField.textProperty());
	from.bindBidirectional(fromTextField.textProperty());
	}

Once the map has been initialized, the DirectionService can be instantiated as well as a MapOptions object to set various attributes about the map. The options are then configured and a GoogleMap object can be instantiated from the map view. The directionsPane is a component which can be used to render the step by step direction text, in this example however, it won’t be displayed.

	@Override
	public void mapInitialized() {
	MapOptions options = new MapOptions();

	options.center(new LatLong(47.606189, –122.335842))
	.zoomControl(true)
	.zoom(12)
	.overviewMapControl(false)
	.mapType(MapTypeIdEnum.ROADMAP);
	GoogleMap map = mapView.createMap(options);
	directionsService = new DirectionsService();
	directionsPane = mapView.getDirec();
	}

view raw

FXMLController.java

hosted with ❤ by GitHub

Finally, the action method defined in the FXML file when the user hits ‘Enter’ in the TextField is below. The method will call the getRoute() method on the DirectionsService class, passing in a boolean value which will define whether the route can be modified by dragging it, the map object, and the DirectionsRequest object.

	@FXML
	private void toTextFieldAction(ActionEvent event) {
	DirectionsRequest request = new DirectionsRequest(from.get(), to.get(), TravelModes.DRIVING);
	directionsService.getRoute(request, this, new DirectionsRenderer(true, mapView.getMap(), directionsPane));
	}

GMapsFX 2.0.9 Released

August 5, 2016 / rterp / 4 Comments

The latest version of GMapsFX has been released which contains a fix for a bug that was preventing the GoogleMapView component from being added as a custom component to SceneBuilder.

The fix will allow the MapView to be added as a custom component. In a future blog post I will detail how to do this.
