We Keep Coding

My Scene changes its color once I add element to it [duplicate]

I have a program that first starts up a little splash screen, and after 5 seconds it continues to a new Stage.
The strange thing is, until now it worked fine, but now that I'm starting to build the new Stage I'm declaring new Nodes in the class to use it.
Now all of the sudden the splash screen has a white background, commenting the before created nodes out will revert the image back to being transparent.
public static Pane pane = new Pane(); //this is fine
//Uncommenting this Node will change the splash screen background white
//public static TextArea textArea = new TextArea();
public static Image splashImage = new Image(Class.class.getClassLoader().getResourceAsStream("image.png"));
public static ImageView splashImageView = new ImageView(splashImage);
public static BorderPane splashPane = new BorderPane(splashImageView);
public static Scene splashScene = new Scene(splashPane);
#Override
public void start(Stage primaryStage) throws Exception {
splashScene.setFill(Color.TRANSPARENT);
primaryStage.setScene(splashScene);
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.show();
}
Here a shortened version of my code
Could this be because of memory issues or something? I have never encountered anything like this.
Any help is appreciated.

The default style sheet is only loaded if a control (i.e an instance of Control or one of its subclasses) is created. (The idea behind this is to avoid the performance overhead of loading CSS for applications that manage all their own graphics and don't use any controls, such as games or simulations.)
The default stylesheet sets the background color of the root node (the splashPane in your example) to a very light grey (specifically, it is 26.4% brighter than the color #ececec).
Since the text area is the only control in your class, creating it causes the default style sheet to be loaded, which sets the background color of the splashPane to a very light grey.
If you need to instantiate controls and want the background of the pane to be transparent, you need to specify that in an external CSS:
splashStyle.css:
.root {
-fx-background-color: transparent ;
}
And
#Override
public void start(Stage primaryStage) throws Exception {
splashScene.setFill(Color.TRANSPARENT);
splashScene.getStylesheets().add("splashStyle.css");
primaryStage.setScene(splashScene);
primaryStage.initStyle(StageStyle.TRANSPARENT);
primaryStage.show();
}
(As a quick check that this will work, you can just test with
splashPane.setStyle("-fx-background-color: transparent; ");
)

JavaFX: Text in button not centered when using custom font

I want to use the "Another Danger" font in my project. However JavaFX isn't quite liking it. Labels and buttons seem to estimate the height of the letters wrong and take a completely wrong size.
I wrote a simple example illustrating the problem:
public class HelloApplication extends Application {
public static void main(String[] args) {
launch();
}
#Override
public void start(Stage stage) {
Button button = new Button("Test");
Scene scene = new Scene(button, 320, 240);
button.setFont(Font.loadFont(HelloApplication.class.getResourceAsStream("/fonts/AnotherDanger-Demo.otf"), 30));
stage.setTitle("Hello!");
stage.setScene(scene);
stage.show();
}
}
The text in the button is clearly not centered. However, when I remove the custom font everything works perfectly. Is this a problem with the font? And if so is there any way to fix this?
I'd be very thankful for any help here.
EDIT: Here are screeshots as requested:

Without the font:

Output formate changed java

I am new in Java. I am trying to learn to make some view in javafx. Here, I am trying to write some simple code to create button in a scene. Button is created successfully but the issue is not showing output properly. And I don't know how to search this type of issue but I look javafx documents. But, didn't find any solution.
Here is my code.
public class PlayingCard extends Application {
#Override
public void start(Stage primaryStage) {
System.out.println("hello world");
primaryStage.setTitle("Button Title");
Button btn = new Button("Click HERE");
StackPane layout = new StackPane();
layout.getChildren().add(btn);
Scene scena = new Scene(layout, 600, 300);
primaryStage.setScene(scena);
primaryStage.show();
}
public static void main(String[] args) {
Application.launch(args);
}
}
I know there is nothing wrong in the code. I missed some setting. Here I am posting output screenshot.
And addition, when I add imageview with some image the same thing like output was not shown.

Not showing typed words correctly in JavaFX with jdk8 in Windows

I'm creating a client application using javafx, and I saw some typing errors in jdk 8. I'm using Myanmar font, in jdk 7, I can see the typed words correctly like the following screen shot when I type q + `(typekey) + q.
But in jdk8, it shows like the following with incorrect format.
Its working perfectly on Mac OS, but not in Windows.
I don't know it is the jdk8's problem or not. Please help me to solve that problem.
Here is my code.`
#Override
public void start(Stage primaryStage) throws Exception {
VBox hbox = new VBox(7);
TextField text = new TextField();
text.setPrefHeight(40);
Button btn1 = new Button();
btn1.setText("Something");
btn1.setMinWidth(110);
hbox.getChildren().addAll(text,btn1);
Scene scene = new Scene(hbox);
primaryStage.setTitle("Version Updater");
primaryStage.setScene(scene);
primaryStage.setWidth(500);
primaryStage.setHeight(350);
primaryStage.show();
}`

Unresizable ever JavaFX Window

My problem is that my JavaFX window expands further than it should at the bottom, thus showing a weird blank background...
I set stage.setResizable(false) but it doesn't seem to work. I also set
stage.setMinWidth(1280);
stage.setMaxWidth(1280);
stage.setMinHeight(800);
stage.setMaxHeight(800);
I think it's due to some ImageView bigger than the window, but I really would like my window to stick to the max I set and be absolutely not resizable ever.
Here's what it looks like : click here
I also noticed it happens only when I set stage.initStyle(StageStyle.TRANSPARENT).
But I don't want my window to be decorated with stage.initStyle(StageStyle.DECORATED)... :(
Thank you in advance for your help. :)

Have you tried directly using setWidth and setHeight:
stage.setWidth(1280);
stage.setHeight(800);
I think the setMaxWidth, setMinHeight... etc. only works on a decorated screen because its main purpose is to limit the sizes the user can set the window. Here's my example:
public class FixedWindowSize extends Application
{
public static void main(String[] args)
{
Application.launch(args);
}
#Override
public void start(Stage primaryStage) throws Exception
{
Pane p = new Pane();
p.setBackground(new Background(new BackgroundFill(Color.RED, null, null)));
p.setMinSize(6000, 6000); //Make this go out beyond window bounds.
Scene s = new Scene(p);
primaryStage.setScene(s);
primaryStage.initStyle(StageStyle.TRANSPARENT);
//This doesn't work
//primaryStage.setMinWidth(1280);
//primaryStage.setMaxWidth(1280);
//primaryStage.setMinHeight(800);
//primaryStage.setMaxHeight(800);
//This should work.
primaryStage.setWidth(1280);
primaryStage.setHeight(800);
primaryStage.show();
}
}
