[scheduler] Allow interacting with events and calendar while event popup is open

[rita-codes]

Currently, clicking outside the event popup closes it but doesn't interact with the underlying content. In Google Calendar, clicking on another event while a popup is open closes the current popup and opens the clicked event's popup in a single action.

We should adopt the same approach:

• Clicking on another event while a popup is open should close the current popup and open the new event's popup.
• Clicking on an empty area of the calendar should close the popup without creating a new event.

Important context: We are changing the default event-creation trigger from double-click to single-click. This means we need to distinguish between:

• Single click while a popup is open → close the popup (no event creation)
• Single click with no popup open → create a new event

Hi @rita-codes, I would like to work on this issue if it is still open.

I had a couple of clarification questions before starting the implementation for this issue:

1. What should be the expected behavior when the user clicks the same event while its pop-up is already open?
   Should it:

   • keep the pop-up open,
   • close the popup,
   • or re-open/refresh it?

2. Which scheduler views should this behavior apply to?
   For example:

   • Day view
   • Week view
   • Month view
   • Timeline/Resource views
   • Any other scheduler variants

Thanks.

Hi @mustafajw07, thanks for picking this up!

To answer your questions:

1. Clicking the same event whose popup is already open → it should close the popup (same behavior as Google Calendar). So clicking the trigger event acts as a toggle.
2. Which views → this should apply to all EventCalendar views (day, week, month, agenda) and EventTimeline.

Feel free to ping me here if anything comes up while you're working on it, happy to help! 🙌

Hi @rita-codes ,
Thanks for the clarification! That behavior makes sense and aligns nicely with Google Calendar UX.
I’ll reach out here if I hit any edge cases or need clarification while implementing. 🙌
