How to Wait for an Exit Event of a Window?

Question

I have this code for a Button:

private void createDeleteButton() {
    Button deleteButton = new Button("Delete");

    deleteButton.addClickListener((Button.ClickEvent e) -> {
        LOG.info("Creating DeleteModal Window");
        DeleteModal deleteModal= new DeleteModal(queryName);
        this.getUI().getUI().addWindow(deleteModal);
        // I want to wait for the exit event of delete modal
        // and then execute the next method
        refresh();
    });
    buttonPanel.addComponent(deleteButton);
}

When I click this button a window appears, but at the same time the refresh(); method is executed

Are there some way to wait for the exit event of deleteModal and then execute the refresh(); method?

Notes:

DeleteModal extends Window

I'm Using Vaadin

The class that contains this method extends VerticalLayout

You can subscribe to window's close event with Window.addCloseListener.

Something like this should work (DISCLAIMER: untested code):

deleteModal.addCloseListener((Window.CloseEvent e) -> refresh());
