Styles are not applyed to Text

[Samyssmile]

@FXML
void onBold(ActionEvent event) {

    IndexRange ir = sctTextEditor.getSelection();

    ArrayList<String> styles = new ArrayList<>();
    styles.add("-fx-font-weight: bold");
    sctTextEditor.setStyle(ir.getStart(), ir.getEnd(), styles);

}

This code not working, is this a issue or my mistake?

Hi, judging by the fact that you are using an ArrayList<String> as your style, I assume that you are using StyledClassedTextArea or its subclass (e.g. CodeArea). This kind of text area expects the strings to be names of CSS style classes that you then refer to from your CSS file. For example:

In Java:

area.setStyle(from, to, Arrays.asList("bold"));

In CSS:

.bold {
    -fx-font-weight: bold;
}
