No, I am afraid you misunderstood me. I am not talking about compatibility with
a third party library.
The "compatibility" already exists and its name is CSS. So, the only thing I
need is to support
'-fx-background-color' for RichParagraph segment.
I've opened an issue today, so, when it is approved there won't be any
questions.
Best regards, Pavel

To be as clear as possible, here's what I need:
.test {
-fx-set-somehow-background-color: green;
}
var builder = RichParagraph.builder();
builder.addWithStyleNames(segment, "test");
because, in parallel for RTFX I simply use its stylesheet:
.test {
-rtfx-background-color: green;
}
So, for both code areas, I use same style classes for styling paragraph
segments.

Right, the API are missing currently. I just point out the fact that
you must use highlights for the purpose of highlighting text range(s) within
the paragraph, since these ranges might contain semi-transparent Nodes. Once
JDK-8355774 is fixed you'll be able to style highlights with CSS and all will
be well. Right?

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.

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
