JavaFX - closing a Tab in TabPane dynamically

Question

I have a TabPane with closable tabs. I want to fire a "close tab event" when the user clicks a button in the content of the tab. Here is the method called when the user clicks the button:

public class CustomTab extends Tab {

    ...

    protected void close() {
        Event.fireEvent(this, new Event(Tab.CLOSED_EVENT));
    }

    ....
}

I add this custom tab to tabpane as:

TabPane tabPane = new TabPane();
...
CustomTab tab = new CustomTab();
tab.setOnClosed(new EventHandler<Event>() {
    @Override
    public void handle(Event t) {
        System.out.println("Closed!");
    }
});
tabPane.getTabs().add(tab);
tabPane.getSelectionModel().select(tab);

Normally, the tabs can be closed by clicking the (default) close icons in the header of the tab, and "Closed!" is printed to the screen. However, when the user clicks the button (that is in the content of the tab) and calls close() method of CustomTab, again, "Closed!" is printed to the screen, but the tab is not closed this time. Isn't it weird?

How can I close a tab upon clicking on an arbitrary button?

P.S.: tabPane.getTabs().remove(tab) works, but firing the corresponding event is much elegant. It should also close the tab.

Answer 1

The approach using only tabPane.getTabs().remove(tab) is not totally correct because it does'nt call the "onClosed" handler if setted. I'm using the following method:

private void closeTab(Tab tab) {
        EventHandler<Event> handler = tab.getOnClosed();
        if (null != handler) {
            handler.handle(null);
        } else {
            tab.getTabPane().getTabs().remove(tab);
        }
    }

which remove the tab if no handler is set or call the "onClosed" handler.
