• If committing a new feature, I have also written an appropriate test suite for it.

I have tested the following:

• [ X] Qalendar component in month mode.
• [ X] Qalendar component in week mode.
• [ X] Qalendar component in day mode.
• [ X] All of the above modes on emulated mobile view.
• [ X] Dragging and dropping events.
• [ X] Resizing events in day/week modes.
• [ X] Clicking events to open event dialog.

This PR solves the following problem**.

There is currently no custom slot for agendaEvent. Have implemented it in line with Tom's suggestion. However, I need a little assistance. I have to change the modeType type to allow a modeType to be agenda, but while it works fine in dev it throws an error when I try to build (related to the modification of modeType). Alternatively, I can fix it by removing agenda from modeType, but then it means the custom agenda will only show when isCustom = true, vs the other modes which allow it to be turned on with isCustom = true or isCustom = ['week']

How to test this PR**.

Custom agenda slot is added to dev. Set isCustom to true or 'agenda' and run to see it.

From a quick look, it looks correct to me that you have added it to the modeType. Makes me wonder what we were thinking back when we didn't do it that way 😄

I can have a look at the TS-errors

Thanks, I'll look at the changes you've suggested tonight and get them resolved!

Cool! I pushed a little something to fix the TS-error in Header.vue

Hey,

I've made those changes. The last thing I need to do is the unit tests.

I was looking through the code but it didn't jump out at me how you determine if your in mobile or desktop view to be in "agenda" mode. I need to mock this in the unit tests to create the customAgenda test. Any chance you know this off the top of your head (or approximately where I should snoop around)?

Cheers

Hi. I've been trying to write some unit tests for the slots before, and was never happy with the way they ended up: so I deleted them and now rely on the Cypress tests instead. For me it's fine the way you've tested it now. The most critical piece of logic added here:

isCustomAgendaEvent() {
      // Logic to determine if this event should use a custom agenda event slot
      if (Array.isArray(this.calendarEvent.isCustom)) {
        return this.calendarEvent.isCustom.includes('agenda');
      }
      return this.calendarEvent.isCustom || false;
    },

is implicitly put under test through a combination of the Cypress-test you wrote, and 09-small-qalendar.cy.ts

I now realized why we didn't add the agenda to the modeType originally: the function that decides whether to render an agenda or the larger month, depends on the screen size, so from the perspective of the implementer, an 'agenda' is not its own mode, but rather a 'month'. Of course, for the isCustom property there will need to be an exception here. This property does now know an agenda mode.

I just broke something, and will need to look through why.

One last thing you could do, is perhaps to document the usage of 'agenda' in the isCustom property.

Great, I'll do the docs update edit: sorry tomorrow night - today was busier than expected.
