• getTooltipInfo

  public TooltipInfo getTooltipInfo​(com.google.gwt.dom.client.Element element)

  Description copied from interface: ComponentConnector

  Gets the tooltip info for the given element.

  When overriding this method, ComponentConnector.hasTooltip() should also be overridden to return true in all situations where this method might return a non-empty result.

  Specified by:

  getTooltipInfo in interface ComponentConnector

  Overrides:

  getTooltipInfo in class AbstractComponentConnector

  Parameters:

  element - The element to lookup a tooltip for

  Returns:

  The tooltip for the element or null if no tooltip is defined for this element.

• hasTooltip

  public boolean hasTooltip()

  Description copied from interface: ComponentConnector

  Check whether there might be a tooltip for this component. The framework will only add event listeners for automatically handling tooltips (using ComponentConnector.getTooltipInfo(Element)) if this method returns true.

  This is only done to optimize performance, so in cases where the status is not known, it's safer to return true so that there will be a tooltip handler even though it might not be needed in all cases.

  Specified by:

  hasTooltip in interface ComponentConnector

  Overrides:

  hasTooltip in class AbstractComponentConnector

  Returns:

  true if some part of the component might have a tooltip, otherwise false
