JavaFX - edit or parse FX-CSS file programmatically

问题

I am using JavaFX 8u60. I want to give my users the chance to edit a CSS file for a pane in my program, without using an external editor.

For example, the user clicks on a Label, and a dialog to select the color is shown. After the user selects the color, the color is actually written in the CSS file, in the appropriate line...

Are there CSS parsers for JavaFX?

I can't show you any Java code because I'm not sure this can be done.

 .table-view .column-header .label{
    -fx-font: 18 GatwickSans;
     -fx-text-fill: red; //<--- user shall be able to edit this line from my program
     -fx-alignment: TOP_LEFT;      
 }

edit: to clarify, I want to be able to edit a FX-CSS file from Java.

You can use color picker, Try this example

Hbox layout =new HBox(10);
ColorPicker colorPicker = new ColorPicker();
colorPicker.setValue(Color.RED);//Red is the default shown at first

Label label =new Label("Your Text");
layout.getChildren().addAll(label,colorPicker);

//Then
colorPicker.setOnAction(event->{
            label.setFill(colorPicker.getValue());
        });

Also for css

colorPicker.setOnAction(event->{
            label.setStyle("-fx-text-fill: "+colorPicker.getValue()+";");
        });

I have used CSSParser:

http://sourceforge.net/projects/cssparser/

It's sufficiently generic and it works a bit like the DOM XML parser. It reads the CSS file and maps it in memory, allowing you to read the single selectors, properties and values, and edit them. Check the discussion on Sourceforge to have some examples, since it lacks documentation.
