Andy, thank you very much for your help.
That doesn’t work for me. As I mentioned before, I’m working with two CodeArea
implementations - JFX and RTFX,
and CSS is the common styling mechanism. I can’t use code for one and CSS for
the other.
Well, technically I could, but it just wouldn’t make any sense.
Best regards, Pavel

You have to use highlights for that, since you can't assign CSS style to a part
of the Text instance, and you can't set a background on it.
JDK-8355774 is pretty high on my list of things to do.

Hello, Andy
Yes, I need to add a background color for a text segment within a paragraph
using CSS.
I have just opened an issue with ID : 9078469.
Can anyone give an estimate of when this issue might be addressed? Background
color is such a fundamental feature
that it's impossible to work without it.
Best regards, Pavel

Dear Pavel:
Can you clarify what you are trying to do exactly?
If you are trying to add a background to a text segment within the
paragraph (as your code seem to indicate), then the only way to do it is to
call Builder.addHighlight().
If you are trying to set the background of the whole paragraph, you've hit
another missing API similar to JDK-8355774 - there is currently no way to style
the paragraphs via CSS. There is the
Builder.setParagraphAttributes(StyleAttributeMap) but a CSS one is missing.

*Subject: *CodeArea: -fx-background-color doesn't work.
For styling CodeArea, I use exclusively style classes, and this is the
foundation of my entire architecture.
Today I tried to implement search highlighting (via background color), but
it didn't work. Below is my test code.
Can anyone tell me how to set the background color using CSS? For example,
in RichTextFX's CodeArea,
they have -rtfx-background-color.
public class JfxCodeArea extends Application {
@Override
public void start(Stage primaryStage) throws Exception {
String text = """
Lorem ipsum dolor sit amet, consectetur adipiscing
elit, sed do eiusmod tempor incididunt
ut labore et dolore magna aliqua. Ut enim ad minim
veniam, quis nostrud exercitation ullamco
laboris nisi ut aliquip ex ea commodo consequat.
Duis aute irure dolor in reprehenderit
in voluptate velit esse cillum dolore eu fugiat
nulla pariatur.
""";
String css = """
.test {
-fx-font-weight: bold;
-fx-fill: red;
-fx-background-color: green;
}
""";
String data = "data:text/css;base64," +
Base64.getEncoder().encodeToString(css.getBytes(StandardCharsets.UTF_8));
CodeArea codeArea = new CodeArea();
codeArea.getStylesheets().add(data);
codeArea.setSyntaxDecorator(new SyntaxDecorator() {
@Override
public RichParagraph createRichParagraph(CodeTextModel model,
int index) {
var builder = RichParagraph.builder();
builder.addWithStyleNames(model.getPlainText(index),
"test");
return builder.build();
}
@Override
public void handleChange(CodeTextModel m, TextPos start,
TextPos end, int charsTop, int linesAdded, int charsBottom) {
}
});
VBox.setVgrow(codeArea, Priority.ALWAYS);
var button = new Button("Go!");
button.setOnAction(e -> codeArea.setText(text));
VBox root = new VBox(codeArea, button);
Scene scene = new Scene(root, 600, 200);
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Best regards, Pavel
