如何删除JavaFX按钮的多次单击事件

Question

I have created a sample fx application with fxml using the scene buidler. I have mapped an action handler on scene builder and write it on the java controller class. By clicking proceed button the screen will change to another screen. But sometime screen will get stuck at that time user will click proceed button multiple time, so the system will crash.

I have added disable property of button at the beginning of action controller, but it is not happening. How to block multiple event click event or just disable button at once clicked?

@FXML
    public void onBtnProceedClick() {
            btnProceed.setDisable(true);
          // other part of method.
}

FXML

<Button fx:id="btnProceed" maxWidth="1.7976931348623157E308" mnemonicParsing="false"
    onAction="#onBtnProceedClick" prefHeight="40.0" prefWidth="-1.0"
    styleClass="btnProceed" text="" GridPane.columnIndex="1"
    GridPane.rowIndex="0"
/>

The event has a getClickCount(). You can add a check to say if getClickCount() > 1 then do nothing and return.
