[Qt-qml] background timers in QML ?

[Sivan Greenberg]

Hi all,

I am wondering if there's a recommended way to have background
timersin Qt Quick apps? My primary use case is an app that reminds me
to do stuff at periodical times, and for that I thought to install a
timer per each item that need be reminded, but I wanted to try and see
if there's a better way or a standard way for that?

Also, it would be nice to have just the timer running firing the app
only when the reminder needs to happen.

Share you experience if you've done this before, and open source code
to learn from would be greatly appreciated :)

Merry Xmas and soon to be Happy New Year,

Thanks!

Remember that QML children have access to parent objects. So if you have
a top of the tree, you can place the timer there and access it from all
the other objects by id name. Personally, I really don't like this, but
it's an option for you.

Another would be to do this in C++ and expose the object by name so it's
available to all of them.
