How to disable buttons in JavaFX?

To disable a button in JavaFX, you can use the setDisable method of the Button class. This method takes a boolean value as an argument, where true disables the button and false enables it.

Here's an example of how to disable a button in JavaFX:

1
2

Button button = new Button("Click me");
button.setDisable(true); // button is now disabled

You can also use this method to enable a disabled button by passing false as the argument:

1

button.setDisable(false); // button is now enabled

You can also use the disableProperty method to bind the disabled state of the button to a boolean property:

1
2

BooleanProperty disabled = new SimpleBooleanProperty(true);
button.disableProperty().bind(disabled);

Now, whenever the value of the disabled property changes, the button's disabled state will be updated accordingly.
