Fix incompatibility with Qt 6.6

[dmytrovoytko]

Please consider this PR to fix #652 so Kanban view works again!

Thank you so much for working on this! I tested your changes locally with Qt 6.6.1 and I can confirm they fix #652.

Pinging @nuttyartist though, since he knows this QML stuff better.

Great that you fixed this!

I don't understand why it fixes it, though. Do you have any documentation explaining why enabled doesn't work but isEnabled does? Is enabled a built-in property we cannot use?

[guihkx]

Is enabled a built-in property we cannot use?

Judging by the error message, that seems to be exactly the case (at least with Qt 6.6):

qrc:/qt/qml/OptionItemButton.qml:15:5: Cannot override FINAL property 
         property bool enabled: true 
         ^

[zjeffer]

Shouldn't we then, instead of renaming it to isEnabled, remove the line where we (re)define the enable property, and use the built-in one instead? Keep in mind I have next to zero experience with QML so I'm talking out of my ass here ;)

[guihkx]

Perhaps, but given that this property was (possibly?) only introduced in Qt 6.6, I'm not sure if we'd be over-complicating the implementation for older Qt versions...

Keep in mind I have next to zero experience with QML so I'm talking out of my ass here ;)

Hey, me too! :)

[zjeffer]

Created a new PR to test the builds: #657

If it works on previous versions, we can close this and merge 657 instead.

[zjeffer]

#657 works, closing in favour of that PR.

Thanks @dmytrovoytko!

[nuttyartist]

Thanks everybody (: I was programming this just when I started studying QML so some of the Kanban code is still rough around the edges. @zjeffer, your PR works just fine. And thanks @dmytrovoytko for spotting this.
