Showing pop-ups


Pop-ups are non-intrusive messages that inform the user whether an action was completed or aborted successfully. Typically they confirm something. Pop-ups look like Post-IT notes. They go away automatically and don’t require user action. Use pop-ups to confirm what the user did and provide them with confidence and assurance.

To show pop-ups, use the standard Vaadin Notification.

Usage examples:

// Send an INFO notification to the current user.
void openInfoNotification(String message) {
    Notification notification =, Notification.Type.HUMANIZED_MESSAGE);

// Send an ERROR notification to the current user.
void openErrorNotification(String message) {, Notification.Type.ERROR_MESSAGE);
