The Tooltip class can be used in two modes:
Automatic Mode: Use the setTooltip method to connect the Tooltip to one or more elements on the page. The Tooltip will automatically monitor events and display the tooltips when the user performs actions that trigger the tooltip. For example:
import { Tooltip } from '@grapecity/wijmo'; let tt = new Tooltip(); tt.setTooltip('#menu', 'Select commands.'); tt.setTooltip('#tree', 'Explore the hierarchy.'); tt.setTooltip('#chart', '#idChartTooltip');
Manual Mode: The caller is responsible for showing and hiding the tooltip using the show and hide methods. For example:
import { Tooltip } from '@grapecity/wijmo'; let tt = new Tooltip(); element.addEventListener('click', () => { if (tt.isVisible) { tt.hide(); } else { tt.show(element, 'This is an important element!'); } });
