I am currently unable to retrieve any results for my fullcalendar tooltip

I am currently working on setting tooltips for events using Primeng's fullcalendar. Despite initializing the tooltip in the web console, I am unable to see it when hovering over an event.

My development environment includes Typescript, Primeng 7.0.5, and Angular 6. I am utilizing PrimeNg's fullcalendar v4.0 and have followed the tooltip example provided in the eventRender page.

Below is a snippet of my code:

loan.component.ts

<div id="calendar" class="row col-xl-12">        
    <p-fullCalendar [events]="events" [options]="options"></p-fullCalendar>
</div>

the result displayed in my console : 

Tooltip {show: ƒ, hide: ƒ, dispose: ƒ, toggle: ƒ, updateTitleContent: ƒ, …}
        dispose: ƒ ()
        hide: ƒ ()
        options: {container: "body", delay: 0, html: false, placement: "top", 
        title: "test", …}
        reference: a.fc-day-grid-event.fc-h-event.fc-event.fc-not-start.fc-end
        show: ƒ ()
        toggle: ƒ ()
        updateTitleContent: ƒ (title)
        _events: (2) [{…}, {…}]
        _isOpen: false
        _popperOptions: {}
        _setTooltipNodeEvent: ƒ (evt, reference, delay, options)
        __proto__: Object

Although the tooltip is initialized, nothing happens when I hover over an event. Has anyone encountered this issue before?

Answer №1

The issue is related to the CSS!

For some reason, the tooltip should change its opacity when hovered over, but it was not working as expected. After manually adjusting the opacity value, it now functions correctly.

Answer №2

I encountered the same issue and found that simply setting CSS properties was not effective for me. I had to specifically include 

encapsulation: ViewEncapsulation.None
in my component decorator.

To address this, I first added the following CSS snippet to my component's style file:

.tooltip{
    opacity: 1 !important;
}

Subsequently, in my component's TypeScript file, I included:

@Component({                 
   encapsulation: ViewEncapsulation.None
})

The event render function in my code looks like this:

eventRender(info) {    
    let tooltip = new Tooltip(info.el, {
    title: '<h6>test</h6>',
    placement: 'top',
    trigger: 'hover',
    container: 'body',
    html: true
    });
}

It is worth noting that the Angular version being used is 8.2 and Full-Calendar version is 4.3.
