java - JavaFX getting buttons from controller to another class -

i have uicontroller class , buttonmethods class. buttonmethods class contains code button actions. need able use buttons controller class in buttonmethods class. example, have these defined in controller class

buttonmethods button = new buttonmethods(); @fxml button buttonlockdown; @fxml button buttonrelease; 

and example, buttonlockdown has actionevent when clicked

@fxml private void actionlockdown(actionevent event) {     button.lockdown(); 

ideally, want buttonmethods this:

public void lockdown() {     buttonlockdown.setdisable(true);     onlockdown = true;      buttonrelease.setdisable(false); 

i can't put code action event various reasons, , putting button objects parameters messy i'm trying do. how can fxml objects button class?

try send uicontroller parameter:

private uicontroller thiscontroller;  @override public void initialize(url url, resourcebundle rb) {     thiscontroller = this; }  @fxml private void actionlockdown(actionevent event) {     button.lockdown(thiscontroller); 

then

public void lockdown(uicontroller controller) {     controller.getbuttonlockdown().setdisable(true);     onlockdown = true;      controller.getbuttonrelease().setdisable(false); 

you can use bindings in appropriate situations.
