java - Using JavaFX to build a GUI for an ATM but having trouble getting primary stage to change scene -
trying use event handlers sync specific button pushes advance next "screen" on atm by: hiding stage, updating stage scene button push creates, , reshowing stage.
i curious if process can taken deep since button newcheckingsaccounts isn't doing should, can go backwards on page , used same code more or less try keep going forward.

} }
i think removing overriding of both buttons in btnewaccount.setonaction() should solve problem:
// creates , registers handler , specifies action button go // create new accounts page btnewaccount.setonaction(new eventhandler<actionevent>() { @override public void handle(actionevent event) { primarystage.hide(); // hold 3 buttons in hbox hbox hbox2 = new hbox(); hbox2.setspacing(10); hbox2.setalignment(pos.center); // ############### removed ################### //button btnewcheckings = new button("make new checkings"); //button btnewsavings = new button("make new savings"); hbox2.getchildren().add(btnewcheckings); hbox2.getchildren().add(btnewsavings); hbox2.getchildren().add(btmain); borderpane borderpane2 = new borderpane(); borderpane2.setbottom(hbox2); borderpane.setalignment(hbox2, pos.center); scene scene2 = new scene(borderpane2, 400, 300); primarystage.settitle("new accounts"); // set stage title primarystage.setscene(scene2); // place scene in stage primarystage.show(); // display stage } }); if want instantiate in actionhandler of button, need declare it's actionhandler in same block.
the way did (actionhandler in start method), work, if use class atributes (buttons) have initialized @ top.
hope :)
