Re: How do you scale a JCheckBox?

What Look & Feel, and what platform do you use?
I found that in JDK 8, only the windows classic
and the windows Look & Feel was scaled to the monitor.

But then in JDK 10, it is that also the following
Look & Feels Metal, Nimbus and CDE/Motif are scaled.
At least this is what a quick testing

on Windows 10 machine showed, that has a 2K display:

I dunno how they do it inder the hood. On the
Mac plattform, they have the class sun.awt.CGraphicsDevice,
which has a field resp. method getScaleFactor(),

and this is used on the Mac plattform in JDK 8.
Maybe JDK 10 uses another strategy, on both the
Windows and Mac plattform. I could only

identify one further difference between JDK 8
and JDK 10 on the Windows platform, with some
guess work:

1) JDK 8, Windows 10, dragging a window:
    If a different monitor is used, the dragged window
    changes resolution, as soon as the mouse lands
    in the different monitor.

    It seems that the resolution change is based
    on some buffer scaling, or somesuch. Not
    sure, fonts are not fine grained, blured, like
    if some interpolation bitmap scaling.

2) JDK 10, Windows 10, dragging a window:
    If a different monitor is used, the dragged window
    changes resolution, as soon as the mouse is
    released.

    It seems that the window is re-validated and/or
    re-painted, or somsesuch. Not sure, fonts are
    much finer. Actually a little bit too fine, as
    if antialiasing would missing.

I consider the mouse behaviour in 2) either a bug
or a compromise. Also I need to adapt to the font
display in 2), not used to that fine fonts.

I resize a window ie pull up a window on a Surface Pro and set view to 300% and all JComponents change size, except for the box portion of the JCheckBoxes.
