Javafx: setting the Mnemonics tab

Question

Quick question: is it possible to set mnemonics for the JavaFX tab?

It seems to me that I can only set them for controls such as buttons and menu items.

Ok, this is an interesting question! You are right, you cannot set the mnemonics directly on the tab. But you can add a component as a tab graph that supports mnemonics:

private class MTab extends Tab
{
    public MTab(String pText)
    {
        super();
        Button fakeLabel = new Button(pText);
        fakeLabel.setMnemonicParsing(true);
        fakeLabel.getStyleClass().clear();
        setGraphic(fakeLabel);
        fakeLabel.setOnAction(ev -> {
            if (getTabPane() != null) {
                getTabPane().getSelectionModel().select(this);
            }
        });
    }
}

Using this tab:

TabPane tabs = new TabPane();
tabs.getTabs().add(new MTab("_this is a test"));
tabs.getTabs().add(new MTab("t_his is a test"));
tabs.getTabs().add(new MTab("th_is is a test"));

Allows you to switch using shortcuts.
