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
