[Lazarus] how to show hourglass on windows 10 with touch screen?

[Alexander Hofmann]

Hi,

I've been looking for something like this, too, some time ago, and I
decided to go for a self-built solution, to be independent of the
underlying widget-set.
(I grayed-out all important widgets, which can be done automatically by
walking, recursively, through the Controls property, and displayed a
"throbber" with a few spinning dots on top of the form)

Anyway,

They do, though not for the "classic" style APIs like Win32 or
Windows.Forms. There's an UWP class
(https://docs.microsoft.com/en-us/uwp/api/Windows.UI.Xaml.Controls.ProgressRing)
I think is intended for this.

In Android it's called "Loading Spinner" IMHO and is somewhat
OS-Supplied, although as I saw in many projects, in the end it's mostly
self-built solutions.

A quick search didn't bring up something similar for other widgetsets,
too (at least GTK and Qt don't seem to support it natively ?)

Best regards,
