Qt Examples Dark Mode Audit (Mojave)

Find what the current status is and prioritize fixing:

• Qt should look reasonably good out-of-the-box, also in dark mode
• Clear roadblocks in Qt that would affect customer apps.
• Some legacy components/examples may remain broken.

• Fusion style button text is dark with low contrast
• Controls do not pick up “live” light/dark theme changes, app restart is needed.
• None of the styles pick up the system accent color.
• Otherwise OK: fusion style dark mode and the dark versions of Material/Universal work well
