JavaFX scene builder questions -

i'm working javafx scene builder , have 2 questions. fisrt one:"how add border pane in javafx scene builder?" second one: "how split cells in hbox?"

i dont know why want join hbox cells can set resize behaviour every child of hbox. there example in hbox's javadoc:

//for example, if hbox needs textfield allocated space:    hbox hbox = new hbox();  textfield field = new textfield();  hbox.sethgrow(field, priority.always);  hbox.getchildren().addall(new label("search:"), field, new button("go")); 

joining cells possible in gridpane row- and/or columnspan.

 gridpane gridpane = new gridpane();  gridpane.add(new button(), 0, 0, 2, 2); // column=0 row=0, spans on 2 columns , 2 rows  gridpane.add(new label(), 3, 1);  // column=3 row=1 (spans on 1 column , 1 row (default)) 

row-/columnspan , vertical horizontal grow can specified in properties bar of scene builder, residing on right side, default.
