I'm trying to add a horizontal line to a linechart in JavaFX. Found this post in SO and now trying to modify it to work in my case, however I'm getting an error, and hopefully someone can see what is the problem here.
Here is the controller code:
package gems.view;
public class GUImainController implements Initializable, Observer
{
final CategoryAxis xAxis = new CategoryAxis();
final NumberAxis yAxis = new NumberAxis();
private ArrayList<Float> tempArr = new ArrayList<>();
private ArrayList<String> tempTimeArray = new ArrayList<>();
private Series<String, Number> tempChart = new Series<>();
#FXML
private LineChartWithMarker<String, Number> lcTemperature = new LineChartWithMarker<>(xAxis,yAxis);
#Override
public void initialize(URL arg0, ResourceBundle arg1)
{
yAxis.setPrefWidth(35);
xAxis.setLabel("Temperature \\u00b0");
yAxis.setLabel("Time");
tempChart = new XYChart.Series<String, Number>();
lcTemperature.getData().add(tempChart);
tempArr.add(observable.getLatestMeasurementsFromServer().getTemperature());
tempTimeArray.add(observable.getLatestMeasurementsFromServer().getDateTime().getTime());
for (int i = 0; i < tempArr.size(); i++)
{
tempChart.getData().add(new XYChart.Data<>(tempTimeArray.get(i), tempArr.get(i)));
}
tempChart.getNode().lookup(".chart-series-line").setStyle("-fx-stroke: orange;");
String s = "test";
Data<String, Number> verticalMarker = new Data<>(s, 20);
lcTemperature.addHorizontalValueMarker(verticalMarker);
}
Here is the LineChartWithMarker class:
package gems.view;
import java.util.Objects;
import javafx.beans.InvalidationListener;
import javafx.beans.Observable;
import javafx.collections.FXCollections;
import javafx.collections.ObservableList;
import javafx.scene.chart.CategoryAxis;
import javafx.scene.chart.LineChart;
import javafx.scene.chart.NumberAxis;
import javafx.scene.shape.Line;
public class LineChartWithMarker<X,Y> extends LineChart
{
private ObservableList<Data<X, Y>> horizontalMarkers;
public LineChartWithMarker(CategoryAxis xAxis, NumberAxis yAxis)
{
super(xAxis, yAxis);
horizontalMarkers = FXCollections.observableArrayList(data -> new Observable[] {data.YValueProperty()});
horizontalMarkers.addListener((InvalidationListener)observable -> layoutPlotChildren());
}
public void addHorizontalValueMarker(Data<X, Y> marker)
{
Objects.requireNonNull(marker, "the marker must not be null");
if (horizontalMarkers.contains(marker)) return;
Line line = new Line();
marker.setNode(line );
getPlotChildren().add(line);
horizontalMarkers.add(marker);
}
public void removeHorizontalValueMarker(Data<X, Y> marker) {
Objects.requireNonNull(marker, "the marker must not be null");
if (marker.getNode() != null) {
getPlotChildren().remove(marker.getNode());
marker.setNode(null);
}
horizontalMarkers.remove(marker);
}
#Override
protected void layoutPlotChildren() {
super.layoutPlotChildren();
for (Data<X, Y> horizontalMarker : horizontalMarkers) {
Line line = (Line) horizontalMarker.getNode();
line.setStartX(0);
line.setEndX(getBoundsInLocal().getWidth());
line.setStartY(getYAxis().getDisplayPosition(horizontalMarker.getYValue()) + 0.5); // 0.5 for crispness
line.setEndY(line.getStartY());
line.toFront();
}
}
}
And here is the FXML (just the part for line chart):
<LineChart fx:id="lcTemperature" minWidth="100.0" prefHeight="155.0" prefWidth="708.0" BorderPane.alignment="CENTER">
<xAxis>
<CategoryAxis side="BOTTOM" />
</xAxis>
<yAxis>
<NumberAxis autoRanging="false" lowerBound="20.0" minorTickCount="10" minorTickLength="10.0" side="LEFT" tickLabelGap="10.0" tickLength="20.0" tickUnit="1.0" upperBound="30.0" />
</yAxis>
</LineChart>

Exception running application gems.view.GUIuserClient
By the way, GUIgems.fxml:42 is the last line of the FXML code I have posted above.
Also, its maybe worth mentioning that the line chart works fine if I am using a simple LineChart, like this:
#FXML
private LineChart<String, Number> lcTemperature;
It does not work when I write like this:
#FXML
private LineChartWithMarker<String, Number> lcTemperature = new LineChartWithMarker<>(xAxis,yAxis);
Alright so I managed to find a solution, if anyone will find themselves in the same situation.
Constructor of LineChartWithMarker needs to look like this:
public LineChartWithMarker(#NamedArg("xAxis") Axis<X> xAxis,
#NamedArg("yAxis") Axis<Y> yAxis)
{
super(xAxis, yAxis);
horizontalMarkers = FXCollections.observableArrayList(data -> new Observable[] {data.YValueProperty()});
horizontalMarkers.addListener((InvalidationListener)observable -> layoutPlotChildren());
}
And the FXML needs to look like this:
<?import gems.view.LineChartWithMarker?>
<LineChartWithMarker fx:id="lcTemperature" minWidth="100.0" prefHeight="155.0" prefWidth="708.0" BorderPane.alignment="CENTER">
<xAxis>
<CategoryAxis side="BOTTOM" />
</xAxis>
<yAxis>
<NumberAxis autoRanging="false" lowerBound="20.0" minorTickCount="10" minorTickLength="10.0" side="LEFT" tickLabelGap="10.0" tickLength="20.0" tickUnit="1.0" upperBound="30.0" />
</yAxis>
</LineChartWithMarker>

Update: The cause is tblTimeDataClock is null.Any idea why?
I am getting a Tableview getItems.AddAll causes java.lang.reflect.InvocationTargetException when calling the getItems().AddAll() method. I have tried following the various examples on the internet but nothing seems so work. The exception occurs at the tblTimeDataClock.getItems().addAll(data) call.
I do see a warning on the new PropertyValue call saying Redundant Type arguments in new expression. Not sure if that has anything to do with it,
What am I doing wrong?
I put together this abbreviated example.
#FXML
private TableView<Test> tblTimeDataClock;
#FXML
private TableColumn<Test, String> colTimeSeconds;
#FXML
private TableColumn<Test, String> colDataVolts;
#FXML
private TableColumn<Test, String> colClockVolts;
#Override
public void initialize(URL url, ResourceBundle rb) {
listTimeDataClockMeasurement = new <Test>ArrayList();
colTimeSeconds.setCellValueFactory(new PropertyValueFactory<Test, String>("n1"));
colDataVolts.setCellValueFactory(new PropertyValueFactory<Test, String>("n2"));
colDataVolts.setCellValueFactory(new PropertyValueFactory<Test, String>("n3"));
ObservableList<Test> data = FXCollections.observableArrayList();
tblTimeDataClock.getItems().addAll(data);
}
The Test class
import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.StringProperty;
public class Test {
private final SimpleStringProperty n1;
private final SimpleStringProperty n2;
private final SimpleStringProperty n3;
public String getN1() {
return n1.get();
}
public String getN2() {
return n2.get();
}
public String getN3() {
return n3.get();
}
public Test(String n1, String n2, String n3) {
this.n1 = new SimpleStringProperty(n1);
this.n2 = new SimpleStringProperty(n2);
this.n3 = new SimpleStringProperty(n3);
}
}
FXML added per request
<content>
<TableView fx:id="tblDataClock" prefHeight="200.0" prefWidth="200.0">
<columns>
<TableColumn fx:id="colTimeSeconds" prefWidth="116.0" text="Time" />
<TableColumn id="colData" fx:id="colDataVolts" prefWidth="127.0" text="Data" />
<TableColumn id="colClock" fx:id="colClockVolts" prefWidth="137.0" text="Clock" />
</columns>
</TableView>
</content>
Looks like the cause might be java.lang.NullPointerException

You forgot to add a Stereotype on your LoginPageController class that's why Spring is telling you:
org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'test.spring.boot.LoginPageController'
As the class is not marked the component-scan will ignore it and there will be no bean register assignable for that type.
Try:
#Controller
public class LoginPageController implements Initializable{
#Autowired
public LoginPageController(UserService userService, private StageManager stageManager){
this.userService = userService;
this.stageManager = stageManager;
}
}

Exception running application vv.MediaMP4
The relevant line in your stack trace is:
Caused by: java.lang.IllegalArgumentException: uri.getScheme() == null! uri == 'pr.mp4'.
You need to specify an URI string with a scheme as a construtor argument, as specified here.
So change your line from this:
Media media = new Media ("pr.mp4");
to something like this:
Media media = new Media("file://c:/myproject/pr.mp4"));
Have a look at this question for more details: How to target a file (a path to it) in Java/JavaFX
I have written a little Clock Widget extending the Text class of JavaFX. To update the Time I am using a Task that basically sets the text to the current System Time. When I run this application in Eclipse it sometimes throws a NullpointerException in the line I call stage.show().
This is what my widgets sourcecode looks like:
package clock;
import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;
import javafx.concurrent.Task;
import javafx.scene.text.Font;
import javafx.scene.text.Text;
public class CurrentClockText extends Text {
private final DateTimeFormatter formatter;
public static final int HOUR = 1;
public static final int HOUR_MINUTE = 2;
public static final int HOUR_MINUTE_SECOND = 3;
public static final int HOUR_MINUTE_SECOND_MILLISECOND = 4;
private final long updateInterval;
private final Task<Void> updater = new Task<Void>() {
#Override
protected Void call() throws Exception {
while (true) {
LocalDateTime now = LocalDateTime.now();
String nowTextual = formatter.format(now);
setText(nowTextual);
try {
Thread.sleep(updateInterval);
} catch (InterruptedException ignore) {
}
}
}
};
public CurrentClockText() {
this(HOUR_MINUTE);
}
public CurrentClockText(final int detailLevel) {
String timeFormat = "";
switch (detailLevel) {
case HOUR:
timeFormat = "HH";
updateInterval = 60000;
break;
case HOUR_MINUTE:
timeFormat = "HH:mm";
updateInterval = 15000;
break;
case HOUR_MINUTE_SECOND:
timeFormat = "HH:mm:ss";
updateInterval = 500;
break;
case HOUR_MINUTE_SECOND_MILLISECOND:
updateInterval = 1;
timeFormat = "HH:mm:ss.S";
break;
default:
throw new IllegalArgumentException(
"Unknown detail level for Clock: " + detailLevel);
}
setFont(new Font("Verdana", 28));
formatter = DateTimeFormatter.ofPattern(timeFormat);
Thread updaterThread = new Thread(updater, "CurrentClockText.updaterThread");
updaterThread.setDaemon(true);
updaterThread.start();
}
}
This is the main class:
package clock;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
public class Boot extends Application {
#Override
public void start(Stage stage) throws Exception {
BorderPane pane = new BorderPane();
CurrentClockText clock = new CurrentClockText(4);
pane.setCenter(clock);
Scene scene = new Scene(pane);
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
Boot.launch(args);
}
}

Exception running application clock.Boot
As I said this Exception only occurs in some runs and not always. It happens mostly when I change the formatting pattern of detailLevel = 4 but remains for another run after changing it back again. I am guessing this might actually have something to do with Eclipse but I can't debug the code either because the Exception gets thrown in the stage.show call which I absolutely do not understand. What's the cause of this random Exception and how can I fix it?
In JavaFX, as in most other GUI toolkits, there is one specific thread which handles all UI related operations. An application must not update the UI outside of this thread. If the UI needs to be updated from another thread, there are usually APIs available which ensure that code is executed in the context of the UI thread. In case of JavaFX, see the Concurrency in JavaFX Tutorial for more information.
In your case, the simplest solution would be to make sure that your setText() call is executed on the JavaFX application thread, not on the thread associated with your Task:
...
Platform.runLater(() -> setText(nowTextual));
...
There are also other APIs available in JavaFX to do animations, which can be used to call a handler method at specific time intervals - that would remove the Thread.sleep() call from your loop. See Timeline for more information.
i have problems with gwt using openlayers and openstreetmaps to get a simple

My Example Code:
public class View implements EntryPoint {
public View() {
}
public void onModuleLoad() {
initMap();
}
private void initMap() {
MapOptions defaultMapOptions = new MapOptions();
MapWidget mapWidget = new MapWidget("684px", "330px", defaultMapOptions);
OSM osm_1 = OSM.Osmarender("Osmarender");
OSM osm_2 = OSM.Mapnik("Mapnik");
OSM osm_3 = OSM.CycleMap("CycleMap");
OSM osm_4 = OSM.Maplint("Maplint");
osm_1.setIsBaseLayer(true);
osm_2.setIsBaseLayer(true);
osm_3.setIsBaseLayer(true);
osm_4.setIsBaseLayer(true);
Map map = mapWidget.getMap();
map.addLayer(osm_1);
map.addLayer(osm_2);
map.addLayer(osm_3);
map.addLayer(osm_4);
map.addControl(new LayerSwitcher());
map.addControl(new MousePosition());
LonLat lonLat = new LonLat(6.95, 50.94);
lonLat.transform("EPSG:4326", "EPSG:900913");
map.setCenter(lonLat, 12);
RootPanel.get().add(mapWidget);
}
Does anybody know how to solve this problem?
After some research I can tell you that osmarender as well as maplint are not supported anymore: http://wiki.openstreetmap.org/wiki/Tiles#home
If you delete those to layers from your function (osm_1 and osm_4) everything works perfectly.
