Avatar

Avatar is a graphical representation of an object or entity, for example a person or an organisation.

Open in a
new tab
Avatar avatarBasic = new Avatar();

Avatar avatarName = new Avatar(name);

Avatar avatarImage = new Avatar(name);
avatarImage.setImage(pictureUrl);
Note
Real-time collaboration
This component is optimized for use with Collaboration Engine—a simple way to build real-time collaboration into your app—but can also be used standalone as a regular component.

Content

Avatar has three properties: name, abbreviation and image.

Name & Abbreviation

The name is shown on hover in a tooltip. When a name is set, Avatar will auto-generate and display an abbreviation of the specified name. For example, “Allison Torres” becomes “AT”, “John Smith” becomes “JS”, etc.

Open in a
new tab
Avatar avatarName = new Avatar(name);

The abbreviation can also be set manually. Abbreviations should be kept to a maximum of 2–3 characters.

Open in a
new tab
Avatar avatarName = new Avatar("Augusta Ada King");

Avatar avatarAbbr = new Avatar("Augusta Ada King");
avatarAbbr.setAbbreviation("AK");

Image

Avatar can be used to display images, such as user profile pictures or company logos. Abbreviations are not shown when images are used.

Open in a
new tab
Avatar user = new Avatar(name);
user.setImage(pictureUrl);

Avatar company = new Avatar("Company Inc.");
StreamResource imageResource = new StreamResource(
  "company-logo.png",
  () -> getClass().getResourceAsStream("/images/company-logo.png"));
company.setImageResource(imageResource);

Avatar Group

Avatar Group is used to group multiple Avatars together. It can be used, for example, to show that there are multiple users viewing the same page or for listing members of a project.

Open in a
new tab
AvatarGroup avatarGroup = new AvatarGroup();

for (Person person : people) {
  String name = person.getFirstName() + " " + person.getLastName();
  AvatarGroupItem avatar = new AvatarGroupItem(name);
  avatarGroup.add(avatar);
}

Max Number of Items

You can specify the max number of items an Avatar Group should display. Items that overflow are grouped into a single Avatar that displays the overflow count. The name of each hidden item is shown on hover in a tooltip. Clicking the overflow item displays the overflowing avatars and names in a list.

Open in a
new tab
AvatarGroup avatarGroup = new AvatarGroup();
avatarGroup.setMaxItemsVisible(3);

for (Person person : people) {
  String name = person.getFirstName() + " " + person.getLastName();
  AvatarGroup.AvatarGroupItem avatar = new AvatarGroup.AvatarGroupItem(name);
  avatarGroup.add(avatar);
}

Background Color

By default, there are 7 different background colors you can use for Avatar. The background color is set using a color index.

Open in a
new tab
AvatarGroup avatarGroup = new AvatarGroup();

for (Person person : people) {
  String name = person.getFirstName() + " " + person.getLastName();
  AvatarGroupItem avatar = new AvatarGroupItem(name);
  avatar.setColorIndex(colorIndex++);
  avatarGroup.add(avatar);
}

Using different background colors can be useful when you need to be able to distinguish between users, for example during collaborative work.
