java - JavaFX css class style -

how can set css style class extends javafx object?

public class diagrampane extends scrollpane implements idiagrameditor {     // .... methods go here }

i've tried following ways in main method:

public class diagrampane extends scrollpane implements idiagrameditor {     diagrampane() {         this.setstyle("-fx-background-color: #f8ecc2;-fx-font-size: 8pt;");         setstyle("-fx-background-color: #f8ecc2;-fx-font-size: 8pt;");     } }

add these lines css file

.diagram-pane {     -fx-background-color: #f8ecc2;     -fx-font-size: 8pt; }

and set diagrampane instance use diagram-pane style class

diagrampane.getstyleclass().clear(); diagrampane.getstyleclass().add("diagram-pane");
