The setStyle() method in JavaFX is like CSS Selectors

Is it possible to bind CSS files to style JavaFX components and also change properties dynamically in code? I'm struggling with the setStyle() method as there's limited documentation available on how to use it effectively.

Instead of modifying the .css file, I'd like to change the hover color directly from the setStyle() method. Here's an example of the existing .css file:

.list-cell:filled:hover 
{
   -fx-background-color: #0093ff;
   -fx-text-fill: white; 
}

I attempted to change the hover color dynamically using the setStyle() method like this:

noteListView.setStyle(
                    ":filled:hover{" +
                    "-fx-background-color: #65ffb0;" +
                    "-fx-text-fill: white;" +
                    "}");

Unfortunately, this approach didn't work. Any guidance would be greatly appreciated. Thank you.

Answer №1

Have you considered trying a similar approach? I recently utilized this method to modify the color of a specific series on a chart based on selections made in a tableview.

table.getSelectionModel().selectedIndexProperty().addListener( (observable, oldValue, newValue) -> changeId(oldValue, newValue));

    public void changeId(Number oldV, Number newV){
    if(oldV.intValue() != -1){
    lineChart.getData().get(oldV.intValue()).getNode().setId("serie-unselect");
    }
    if(newV.intValue() != -1){
    lineChart.getData().get(newV.intValue()).getNode().setId("serie-select");
    }
    }

Afterwards, make sure to include #serie-select{} and #serie-unselect{} with appropriate styling options in your css file.
