Re: [Interest] sizeHint for delegates not wqorking
Ah, thanks a lot! That did indeed fix it.

Re: [Interest] Duration property of PropertyAnimation
Probably not the most helpful, but you could more easily fix this by doing a
Behavior on the animation instead. But this is a reverse handling, the
Transform will hold the Behavior which hold the NumberAnimation. The bahavior
have an enabled property.
http://doc.qt.io/qt-5/qml-qtquick-behavior.html
Maybe this could help.

Subject: [Interest] Duration property of PropertyAnimation
Hi to all,
I'm working on a project that use Qt 5.9.2 on RPi3B+, with eglfs platform.
Here a full working code:

The purpose of this code is to animate an image like a clock hand. Of
course this is a simple example, my actual code is more complex. The
approach is to animate the needle for 30 degrees (360 / 12) and then
advance for other 30 degrees. This is because I will need to stop the
animation when certain conditions are met (i.e. I cannot set the
animation 'to' property to 360 * N)
It works fine if the duration property is above about 45 ms. Below this
threshold the animation doesn't speed up anymore. The docs say nothing
about a minimum value.
I'm aware the refresh rate of the monitor doesn't allow faster
animation, but I would expect the animation would complete in the given
time (duration) even without any intermediate frames.
The problem here is instead it takes the same amount of time! I mean,
even if I set duration = 10 ms, it take the same amount of time like
when duration = 40 ms. Hence, I think it would complete a whole cycle in
120 ms, instead it takes something like 480 ms!
Is there a way to force PropertyAnimation to honor the duration property
even if it cannot draw intermediate frames?
Best regards
Marco
