I am trying to create a Javafx game and I want the user to be able to input their name using a dialogue. The problem is that when I try to position the dialogue using setY() or setX() nothing changes. I should note that I am using an online IDE so if this is the problem please somebody tell me.
import javafx.stage.Modality;
import javafx.scene.control.*;
import javafx.scene.control.Dialog;
import javafx.geometry.*;
import javafx.stage.Stage;
import javafx.scene.Scene;
public class Main extends Application {
#Override
public void start(Stage primaryStage) {
VBox page = new VBox();
Scene scene = new Scene(page, 600, 700);
primaryStage.setScene(scene);
primaryStage.show();
setUserName();
}
public static void setUserName() {
Dialog<String> dialog = new Dialog<String>();
dialog.setTitle("Dialog");
ButtonType type = new ButtonType("Ok", ButtonData.OK_DONE);
dialog.initModality(Modality.APPLICATION_MODAL);
dialog.initStyle(StageStyle.UNDECORATED);
dialog.setContentText("Hello World");
dialog.setY(100);
dialog.showAndWait();
}
public static void main(String[] args) {
launch(args);
}
}

When opening a JavaFX FileChooser within a Stage (only way to make it modal), there is an annoying "Genie" effect (see code and movie below). How can it be disabled ?
import javafx.application.Platform;
import javafx.embed.swing.JFXPanel;
import javafx.stage.Stage;
import javafx.stage.FileChooser;
import javafx.concurrent.Task;
public class Test {
private static void initFX() {
// This method is invoked on the JavaFX thread
Stage stage = new Stage();
FileChooser fileChooser = new FileChooser();
stage.setMaxHeight(0);
stage.setWidth(0);
stage.setTitle("Choose an file");
stage.setResizable(false);
stage.setAlwaysOnTop(true);
stage.show();
fileChooser.showOpenDialog(stage);
stage.hide();
}
public static void main(String[] args) {
final JFXPanel fxPanel = new JFXPanel();
Platform.runLater(new Runnable() {
#Override
public void run() {
initFX();
}
});
}
}
I have a factory method that gives me a ChoiceBox with a bidirectional binding to an enum property. The choice box works as expected, except that it doesn't show the initial value set in the property constructor. Instead the choice box shows up initially as blank, not showing any value. What's wrong?
Here's an MRE:
import javafx.application.Application;
import javafx.beans.binding.Bindings;
import javafx.beans.property.ObjectProperty;
import javafx.beans.property.SimpleObjectProperty;
import javafx.scene.Scene;
import javafx.scene.control.ChoiceBox;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ChoiceBoxMRE extends Application {
private ObjectProperty<Table> table = new SimpleObjectProperty<>(Table.BIG);
public static void main(String[] args) {
launch(args);
}
#Override
public void start(Stage primaryStage) {
VBox vBox = new VBox();
vBox.getChildren().add(getChoiceBox(table));
primaryStage.setScene(new Scene(vBox));
primaryStage.show();
}
private <T extends Enum<T>> ChoiceBox<T> getChoiceBox(ObjectProperty<T> objectProperty) {
ChoiceBox<T> choiceBox = new ChoiceBox<>();
choiceBox.getItems()
.addAll(objectProperty.getValue().getDeclaringClass().getEnumConstants());
Bindings.bindBidirectional(objectProperty, choiceBox.valueProperty());
return choiceBox;
}
enum Table {
BIG, SMALL;
}
}
I am not sure if that is a bug or not, but there is a simple workaround: simply select the value prior to binding it:
choiceBox.getSelectionModel().select(objectProperty.get());
I've been working a lot in JavaFX lately, by writing code only -- no CSS no FXML and I want to keep it that way. I've managed to do all of the stuff I wanted that way except that now I can't set the text color of TextField without using CSS, so I'm asking for advice here. Is there any way to do it, no matter how hacky it is?
Note that I'm still using Java 8 version.
Considering your points : "No CSS" and "how hacky it can be.." below is one way to achieve the text coloring.
import com.sun.javafx.scene.control.skin.TextFieldSkin;
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.layout.StackPane;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
public class TextField_TextColor_Demo extends Application {
#Override
public void start(Stage primaryStage) throws Exception {
TextField textField = new TextField();
textField.setSkin(new TextFieldSkin(textField){
#Override
protected void layoutChildren(double x, double y, double w, double h) {
super.layoutChildren(x, y, w, h);
if(textField.getProperties().get("colorChanged")==null) {
textFill.setValue(Color.RED);
textField.getProperties().put("colorChanged",true);
}
}
});
StackPane root = new StackPane(textField);
Scene scene = new Scene(root, 300,300);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String... args){
Application.launch(args);
}
}
I could not make it work. But made another solution. Although the caret color also changes.
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.TextField;
import javafx.scene.control.skin.TextFieldSkin;
import javafx.scene.layout.HBox;
import javafx.scene.paint.Color;
import javafx.scene.paint.Paint;
import javafx.stage.Stage;
public class TextField_TextColor_Demo extends Application {
#Override
public void start(Stage stage) throws Exception {
TextField txt = new TextField();
CustomTextFieldSkin skin = new CustomTextFieldSkin(txt);
txt.setSkin(skin);
skin.setHighlight(Color.RED);
HBox box = new HBox(txt);;
Scene scene = new Scene(box, 300, 100);
stage.setScene(scene);
stage.show();
}
public class CustomTextFieldSkin extends TextFieldSkin{
public CustomTextFieldSkin(TextField textField) {
super(textField);
}
public void setHighlight(Paint value) {
setTextFill(value);
}
}
public static void main(String... args){
Application.launch(args);
}
}
Seems it is possible to color the caret separately, according these two answers:
https://stackoverflow.com/a/47876289/7989121
https://stackoverflow.com/a/27323035/7989121
Both use caretPath though, which I could not use due it not being visible according to my IDE
I want to create a simple project in JavaFx, which can support Oracle forms 10g. currently code i'm using can render and HTML page but i unable to render any Oracle forms 10g. Is it possible to run oracle form 10g in javaFx browser and how ?

When I add image and text to a button, by default elements are set horizontally. How can I change this behavior to get text under image ?
Set the contentDisplayProperty on the button.
button.setContentDisplay(ContentDisplay.TOP);
Here is an executable example:
import javafx.application.Application;
import javafx.event.*;
import javafx.geometry.Pos;
import javafx.scene.Scene;
import javafx.scene.control.*;
import javafx.scene.image.*;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class ButtonGraphicTest extends Application {
#Override public void start(final Stage stage) throws Exception {
final Label response = new Label();
final ImageView imageView = new ImageView(
new Image("http://icons.iconarchive.com/icons/eponas-deeway/colobrush/128/heart-2-icon.png")
);
final Button button = new Button("I love you", imageView);
button.setStyle("-fx-base: coral;");
button.setContentDisplay(ContentDisplay.TOP);
button.setOnAction(new EventHandler<ActionEvent>() {
#Override public void handle(ActionEvent event) {
response.setText("I love you too!");
}
});
final VBox layout = new VBox(10);
layout.setAlignment(Pos.CENTER);
layout.getChildren().addAll(button, response);
layout.setStyle("-fx-background-color: cornsilk; -fx-padding: 10; -fx-font-size: 20;");
stage.setScene(new Scene(layout));
stage.show();
}
public static void main(String[] args) { launch(args); }
}
