Alert

Alerts inform the user of important information or important action required. They are non-disruptive to a user's experience and do not require to interrupt the user's task.

Basic alerts

Alert severity

The alert offers five severity levels that set a distinctive icon and color.

<QtmAlert
  message="This is an error alert — check it out!"
  severity="error"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is a warning alert — check it out!"
  severity="warning"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is a success alert — check it out!"
  severity="success"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is an informative alert — check it out!"
  severity="informative"
  dismissible={false}
></QtmAlert>
  <QtmAlert
  message="This is a neutral alert — check it out!"
  severity="neutral"
  dismissible={false}
></QtmAlert>

Title

You can use title property to display a formatted title.

<QtmAlert
  message="This is an informative alert — check it out!"
  severity="informative"
  title="Title"
  dismissible={false}
></QtmAlert>

Message

You can use message property or children to display a formatted message.

This is an error alert — check it out!

<QtmAlert severity="error" title="Error" dismissible={false}>
  This is an error alert — <strong>check it out!</strong>
</QtmAlert>

Action buttons

An alert can have actions, such as a close or undo button. It is rendered after the message, at the end of the alert. To add action buttons to an alert, set actionButtons property to an array of action buttons.

By default a close button is displayed. You can remove it by setting the dismissible prop to false.

<QtmAlert
  message="This is an informative alert — check it out!"
  severity="informative"
  actionButtons={[{ text: 'UNDO', icon: 'undo', onClick: () => {} }]}
  onClose={() => console.log('Alert closed')}
></QtmAlert>

Icons

You can change the default severity to icon mapping with the iconMapping prop.

By default, the iconMapping has the following format:

{
  informative: 'info',
  success: 'check_circle',
  error: 'error_outline',
  warning: 'warning_amber',
};

<QtmAlert
  message="This is a success alert"
  severity="success"
  dismissible={false}
  iconMapping={{ success: 'done' }}
></QtmAlert>

Color

The color prop will override the default color for the specified severity.

<QtmAlert
  message="This is an alert with an error color — check it out!"
  color="error"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is an alert with a warning color — check it out!"
  color="warning"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is an alert with a success color — check it out!"
  color="success"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is an alert with an informative — check it out!"
  color="informative"
  dismissible={false}
></QtmAlert>
<QtmAlert
  message="This is an alert with a neutral color — check it out!"
  color="neutral"
  dismissible={false}
></QtmAlert>
