-

i want load image borderpane. have static java method makes task more complicated me:

private static final image iv;         static {         iv = new image(startpanel.class.getclass().getresource("/images/system-help.png").toexternalform());     }  public static void insert(){       bp.setcenter(iv); }

p.s 2 managed load image code:

    private static final imageview iv;             static {             iv = new imageview(startpanel.class.getresource("/com/dx57dc/images/6.jpg").toexternalform());         }  borderpane.setcenter(iv);

i got work. not need handle image load. trick use style property:

borderpane.setstyle("-fx-background-image: url(\"/images/system-help.png\");-fx-background-size: 500, 500;-fx-background-repeat: no-repeat;")

for sure should outsource css file , not use inline styles. it's easier show.

if want set background of center area use this:

borderpane.getcenter().setstyle("-fx-background-image: url(\"/images/system-help.png\");-fx-background-size: 500, 500;-fx-background-repeat: no-repeat;")

note:
system-help.png located in /images directory, @ same level class file application (e.g. using eclipse must stored in bin folder, means add folder (for example call resources) project , use source folder, in folder need image folder. kinda weird thats how fx needs it).

edit: resize following:

private static final imageview iv;     static {             iv = new imageview(startpanel.class.getresource("/com/dx57dc/images/6.jpg").toexternalform());             iv.resize(100, 100);         }
