[Ctk-developers] ctkSliderWidget on ctkPopUpWidget: spinbox never gets keyboard focus

[Julien Finet]

Hi Miklos,

This is great news !
The patch looks good to me. Did you try it on windows, linux and mac ?

Before merging, let's make sure Slicer still works with that change.
I'm on vacation this week so it will be a challenge for me to run those
tests, Jc, do you have time to try it ?

Julien.
