Keytips

For more details and examples visit the official docs. The R package cannot handle each and every case, so for advanced use cases you need to work using the original docs to achieve the desired result.

Value

Object with shiny.tag class suitable for use in the UI of a Shiny app.

Details

• componentRef IRefObject<IKeytipLayer>
  Optional callback to access the KeytipLayer component. Use this instead of ref for accessing the public methods and properties of the component.

• content string
  String to put inside the layer to be used for the aria-describedby for the component with the keytip Should be one of the starting sequences

• keytipExitSequences IKeytipTransitionKey[]
  List of key sequences that will exit keytips mode

• keytipReturnSequences IKeytipTransitionKey[]
  List of key sequences that execute the return functionality in keytips (going back to the previous level of keytips)

• keytipStartSequences IKeytipTransitionKey[]
  List of key sequences that will start keytips mode

• onEnterKeytipMode () => void
  Callback function triggered when keytip mode is entered

• onExitKeytipMode (ev?: React.KeyboardEvent<HTMLElement> | React.MouseEvent<HTMLElement>) => void
  Callback function triggered when keytip mode is exited. ev is the Mouse or Keyboard Event that triggered the exit, if any.

• styles IStyleFunctionOrObject<IKeytipLayerStyleProps, IKeytipLayerStyles>
  (Optional) Call to provide customized styling.

• calloutProps ICalloutProps
  ICalloutProps to pass to the callout element

• content string
  Content to put inside the keytip

• disabled boolean
  T/F if the corresponding control for this keytip is disabled

• hasDynamicChildren boolean
  Whether or not this keytip will have children keytips that are dynamically created (DOM is generated on keytip activation). Common cases are a Pivot or Modal.

• hasMenu boolean
  Whether or not this keytip belongs to a component that has a menu Keytip mode will stay on when a menu is opened, even if the items in that menu have no keytips

• keySequences string[]
  Array of KeySequences which is the full key sequence to trigger this keytip Should not include initial 'start' key sequence

• offset Point
  Offset x and y for the keytip, added from the top-left corner By default the keytip will be anchored to the bottom-center of the element

• onExecute (executeTarget: HTMLElement | null, target: HTMLElement | null) => void
  Function to call when this keytip is activated. 'executeTarget' is the DOM element marked with 'data-ktp-execute-target'. 'target' is the DOM element marked with 'data-ktp-target'.

• onReturn (executeTarget: HTMLElement | null, target: HTMLElement | null) => void
  Function to call when the keytip is the currentKeytip and a return sequence is pressed. 'executeTarget' is the DOM element marked with 'data-ktp-execute-target'. 'target' is the DOM element marked with 'data-ktp-target'.

• overflowSetSequence string[]
  Full KeySequence of the overflow set button, will be set automatically if this keytip is inside an overflow

• styles IStyleFunctionOrObject<IKeytipStyleProps, IKeytipStyles>
  Optional styles for the component.

• theme ITheme
  Theme for the component

• visible boolean
  T/F if the keytip is visible
