border - JavaFX: Making BorderPane's Center's contents not strech -


just quick 1 since i'm inexperienced in designing apps. appreciated.

i've got following application, , it's obvious uses borderpane layout. i've got gridpane of 5 labels , 5 textfields in center region, , wanted subtle border it.

screenshot

as can see, gridpane utilizes full space allocated in center region, , although border gets drawn nicely, goes way down bottom of center region (red arrows). what want finish @ blue line.

i tried using grid.setprefheight(400);, example, didn't work.

are there solutions other obvious one, add second container below gridpane , squeeze upper container enough?

edit: reference, code creates center area gridpane:

public gridpane addgridpanecenter() { gridpane grid = new gridpane(); grid.sethgap(10); grid.setvgap(10); grid.setpadding(new insets(0, 10, 0, 10));  sihuid = new text("sihu id:"); sihuid.setfont(font.font("inconsolata", 16)); grid.add(sihuid, 0, 1);                                           //spans 0,1 1,1 (column-row) sihuid_tf = new textfield(); sihuid_tf.seteditable(false); grid.add(sihuid_tf, 1, 1);  mac = new text("plug mac:"); mac.setfont(font.font("inconsolata", 16)); grid.add(mac, 0, 2); mac_tf = new textfield(); mac_tf.seteditable(false); grid.add(mac_tf, 1, 2);  loc = new text("location:"); loc.setfont(font.font("inconsolata", 16)); grid.add(loc, 0, 3); loc_tf = new textfield(); loc_tf.seteditable(false); grid.add(loc_tf, 1, 3);  appl = new text("appliance:"); appl.setfont(font.font("inconsolata", 16)); grid.add(appl, 0, 4); appl_tf = new textfield(); appl_tf.seteditable(false); grid.add(appl_tf, 1, 4);  type = new text("type:"); type.setfont(font.font("inconsolata", 16)); grid.add(type, 0, 5); type_tf = new textfield(); type_tf.seteditable(false); grid.add(type_tf, 1, 5);  grid.setprefheight(400); grid.setstyle(     "-fx-border-color: #b8b8ba; -fx-border-width: 1;"     + "-fx-border-radius: 4;"     /*+ "-fx-font: " + "inconsolata" + ";" */ );  return grid;

}

after that, there's simple 

gridpane grid_center = addgridpanecenter();                             //center grid, contains info plugs.         border_pane.setcenter(grid_center);      scene scene = new scene(border_pane, 900, 700);     scene.setfill(color.ghostwhite);      primarystage.settitle("plugcontrol v0.1e");     primarystage.setscene(scene);     primarystage.show();

i'm afraid behaviour of borderpane design (ref):

the top , bottom children resized preferred heights , extend width of borderpane. left , right children resized preferred widths , extend length between top , bottom nodes. and center node resized fill available space in middle.

you should put gridpane in anchorpane or vbox , put (anchorpane or vbox) in center of borderpane.
