Notifications and Banners
Notifications and banners allow your solution to keep users informed about events and system status.
A notification is a small window that appears in the lower right corner of the application and fades out after ten seconds.
- Use a notification to display noncritical system status information such as completed or failed tasks and alerts.
- Because a notification windows is temporarily displayed, don't use it for information that requires the user's immediate attention. In this case, a message dialog is a better choice.
- Ensure that the information in a notification persists elsewhere in the UI so that users can view it at a later time. In vSphere Web Client, users can view notification messages:
- In the All tab in the Recent Tasks portlet
- In the Tasks and Events consoles
- If the notification is for a failure, in the Failed tab of the Recent Tasks portlet and the object's Monitor > Issues tab
- Write complete sentences and use ending punctuation.
A banner is yellow bar that contains a noncritical message. A banner persists in the UI until the user closes it.
- Use a banner:
- In the application chrome, to communicate important information about the status of the system
- In the main content area, to highlight issues that require users' attention
- In a dialog or wizard, to show a problem found when the user moves between pages or finishes the window. See the Validation standard.
- Always display a banner above the midline of the application.
- Provide short, yet informative error text.
The minimum size of a notification window is 250 x 80 pixels. At this size, your notification can include two lines of text. The maximum size is 350 x 350 pixels.
