How can I use mnemonics on JavaFX 8 Alerts

Question

I would like to be able to add accelerator keys for the buttons that are provided as a part of the Alert Dialog Controls included with JavaFX.

I am unsure if this is possible using the standard alert types ERROR, INFORMATION, CONFIRMATION, WARNING?

I created my own login window - which doesn't use an Alert structure and it works as follows:

When the stage opens up.

Then when the user hits the "ALT" key:

I would like the ability to "Hot Key" the buttons on the Alerts in the system. However, I am unsure if I can use the standard alerts, or if I need to create my own, and if so, how should I do that.

I really would like to use the Dialogs natively, if at all possible.

Thanks.

When setting mnemonics inside FXML they are done with an underscore, like "_Menu", have checked that? — FibreFoX, Dec 17 '15 at 13:07
These are Alerts so I am not creating them in FXML. Alert a = new Alert(AlertType.Confirmation); a.show(). — purring pigeon, Dec 17 '15 at 14:42
As far as I understood your requirements, you need something like [Custom Login Dialog](http://code.makery.ch/blog/javafx-dialogs-official/), which works with pure JavaFX 8 — FibreFoX, Dec 17 '15 at 14:48
I have my dialog working, I was asking about alerts in general. — purring pigeon, Dec 17 '15 at 19:32

As far as I understood your question, I think it isn't possible without some extra code.

Looking at the code of OpenJFX the labels of the buttons are localized and fixed.

You might just want to create some buttons on your own by using the apropiate constructor which takes some buttons where you can override the existing ones.

EDIT: after rethinking everything, I tried to recreate your problem. You can see that project on GitHub..

This is the special code:

public void showCustomizedAlertWindow() {
    Alert a = new Alert(AlertType.CONFIRMATION, "some content text", ButtonType.OK, ButtonType.CANCEL, ButtonType.FINISH);
    ((Button) a.getDialogPane().lookupButton(ButtonType.FINISH)).setText("_finished");
    a.show();
}

But be aware, you are removing localization-support of that buttons.
