Rectangle.tooltipDelay Property
        
 Gets or sets the delay in milliseconds after hovering over this adapter with a mouse before its tooltip is displayed.
 This is generally only used by non-data (getSupportedSettings().isDataSupported) adapters, and will be ignored for data adapters
 as they have custom properties for more complex tooltips.
