Label doesn't scale down correctly to 0.07f, but if I use font.setUseIntegerPositions(false), it shows both label and font in libGDX

I try to make a label to display "You Win" and add it to winStage, but I cannot manage to display the label correctly on winStage. Some words don't show on the screen, and if I downscale further than 0.044f, the String disappears. when I add font.setUseIntegerPositions(false) to my code, the font shows correct, but the wrong label also shows. Is there a way to get this work? (hide the wrong label or get the label shows correctly), code uses Kotlin, but very similar to java
YUW N is the wrong label I want to remove, the correct "You Win" only shows when I add font.setUseIntegerPositions(false)
here's the relevant code part
private val winViewport = StretchViewport(mainStage.width, mainStage.height)
val winStage = Stage(winViewport, winBatch)
var font = BitmapFont()
var labelStyle = Label.LabelStyle()
labelStyle.font = font
labelStyle.fontColor = Color.RED
var label2 = Label("YOU WIN", labelStyle)
label2.setBounds(0f, winStage.height*2/3, winStage.width*1, winStage.height/6)
label2.setFontScale(0.07F) // 0.07f
font.setUseIntegerPositions(false)
label2.setWrap(false)
winStage.addActor(label2)
winStage.act(delta)
winStage.draw()

How to make SWT button Text BOLD

I am creating a checkbox button with text in SWT.
org.eclipse.swt.widgets.Button button= new Button(composite, SWT.CHECK);
button.setText(Messages.AnswerDialog_answer);
button.setSelection(true);
In messages.properties, I have the value
AnswerDialog_answer=Answer
How can i show the text(ie. Answer) of this button in BOLD?

You can convert the currently assigned font for the button to be bold using something like:
FontData [] data = button.getFont().getFontData();
for (FontData datum : data) {
datum.setStyle(SWT.BOLD);
}
Font boldFont = new Font(button.getDisplay(), data);
button.setFont(boldFont);
Note: You must call boldFont.dispose() when you are done with the font (such as when the dialog closes).
I'm not sure that all platforms support changing the button font. The above code works on macOS.

java awt color chooser does't show in proper way in JavaFx

#FXML
Private void handleItemBackAction(ActionEvent eve)
{
java.awt.Color color=JColorChooser.showDialog(null,"Select a color",java.awt.Color.CYAN);
String hex = Integer.toHexString(color.getRGB() & 0xffffff);
hex="#"+hex;
Text.setText(hex);
ShortcutButton.setStyle("-fx-background-color: " + hex + ";");
}
When I run this window and click on button at first time color chooser goes behind my actual pane.
When I click on button second time while running it shows at top of all other pane which is correct and so on it works properly.
Then why color chooser not shows in front first time on button click?

The first argument to JColorChooser.showDialog is the parent component of the dialog. You told that method to show the dialog with no parent, so it doesn't know about your other windows.
Instead of using JColorChooser.showDialog, you'll need to embed a JColorChooser instance inside a JavaFX dialog or window:
JColorChooser colorChooser = new JColorChooser(java.awt.Color.CYAN);
SwingNode colorChooserNode = new SwingNode();
colorChooserNode.setContent(colorChooser);
Alert dialog = new Alert(Alert.AlertType.NONE);
// Guarantees dialog will be above (and will block input to) mainStage.
dialog.initOwner(mainStage);
dialog.setTitle("Select a color");
dialog.getDialogPane().setContent(colorChooserNode);
dialog.getDialogPane().getButtonTypes().setAll(
ButtonType.OK, ButtonType.CANCEL);
Optional<ButtonType> response = dialog.showAndWait();
if (response.filter(r -> r == ButtonType.OK).isPresent()) {
int rgb = colorChooser.getColor().getRGB();
String hex = String.format("#%06x", rgb & 0xffffff);
Text.setText(hex);
ShortcutButton.setBackground(new Background(
new BackgroundFill(Color.valueOf(hex), null, null)));
} else {
System.out.println("User canceled");
}
Of course, you're probably better off using ColorPicker in your main window, so you don't have to create an explicit dialog at all:
final ColorPicker colorPicker = new ColorPicker(Color.CYAN);
colorPicker.setOnAction(e -> {
Color color = colorPicker.getValue();
String hex = String.format("#%02x02x02x",
(int) (color.getRed() * 255),
(int) (color.getGreen() * 255),
(int) (color.getBlue() * 255));
Text.setText(hex);
ShortcutButton.setBackground(
new Background(new BackgroundFill(color, null, null)));
});
myLayoutPane.getChildren().add(colorPicker);
As an aside, Java variable names should always start with a lowercase letter, to make them easy to distinguish from class names. Consider changing Text to text, and ShortcutButton to shortcutButton.

Programatically open a menu from menubar(Simulate the menu click programmatically for UI automation test)

MenuManager and MenuContribution items has been already created.
For the input Menu Item id/label, I need to problematically drop-down/open/display a menu item from menubar in Eclipse. I think I may need to fire some event.
This is requirement for UI Automation that Menu should be drop down automatically.
Can you please help at the earliest. I'm trying following, but here not sure how to set the x & y co-ordinates where mouse click event should be fired.
Code:
String toCompare = "File";
Menu menu = window.getShell().getMenuBar();
if(menu!=null && !menu.isDisposed()){
MenuItem[] items = menu.getItems();
for(int i=0;i<items.length;i++){
String menuText = LegacyActionTools.removeMnemonics(items[i].getText());
if(toCompare.equalsIgnoreCase(menuText)){
Event event = new Event();
event.doit = true;
event.widget = items[i];
event.type = SWT.MouseDown;
event.button = 1;
boolean success = items[i].getDisplay().post(event);
System.out.println("Could we generate the event ? "+success);
}
}
}

Why don't you use dedicated tools for UI testing, such as SWTBot. It seems typicall matche what you would do

How do I set the text in it at the beginning when the dialog opens?

I have the following code that displays a JDialog, it shows a text field, I assume it's a JTextField.
How do I set the text in it at the beginning when the dialog opens?
JOptionPane pane = new JOptionPane("", JOptionPane.QUESTION_MESSAGE);
pane.setWantsInput(true);
JDialog dialog = pane.createDialog(null, "Test");
dialog.setModalityType(Dialog.ModalityType.APPLICATION_MODAL);
dialog.setVisible(true);

Use:
pane.setInitialSelectionValue("foo");
to set the input value that is initially displayed as selected to the user.
