java - Cannot Maximize Window with JavaFX -

i made custom minimize button way:

public minimizebutton() {     button button = new button("-");     button.getstyleclass().clear();     button.getstyleclass().add("actionbutton");     button.setonaction(new eventhandler<actionevent>() {         @override         public void handle(actionevent event) {             stage stage = (stage) ((button) event.getsource()).getscene().getwindow();             stage.seticonified(true);         }     });     this.getchildren().add(button); } 

and called

primarystage.initstyle(stagestyle.undecorated); 

the button working well.

the issue when try maximize window once stage iconified, takes couple of seconds window redraw stage.

any ideas on how make "maximizing process" of window faster?

fixed using

primarystage.initstyle(stagestyle.transparent); 

instead of

primarystage.initstyle(stagestyle.undecorated);
