I have been able to build CMB+SMTK linked to Qt 5.12 on macos 10.14 (mojave) using the Qt binaries from homebrew (i.e., a bottled build). I have not done extensive testing.
Dark mode seems to work.
However, I did have to mark modelbuilder to run in “low resolution” mode, using Finder’s information dialog:
in order to avoid a rendering problem:
Note that the quarter-sized render area problem is independent of dark mode. However, this rendering issue only occurs when running the application in a debugger started in a terminal. Running the application by double-clicking never seems to suffer from the problem.
@cory.quammen This is the same rendering issue I have been having with ParaView (and is exhibited by the ParaView build in the modelbuilder superbuild). So at least I have a workaround (run in low resolution mode or start the app using Finder).

This looks great!

@dcthomp I have just built using Qt 5.12.0 from their installer. In my build, both ParaView and ModelBuilder have no GUI elements (despite their being enabled in the `View` menu). Any suggestions?

Have you verified that Qt applications bundled with your Qt build run properly? For example, can you run Qt Designer.app?

Yup, it runs just fine. @Bob_Obara Have you given this a shot yet? Maybe I am just lucky.

Hmm, ModelBuilder renders just fine when I build it outside of the superbuild. I’ll bet there’s something funny with my superbuild’s configuration. Sorry for the noise!

Here is what I got from running modelbuilder in superbuild/cmb/build with Qt5.12 on the new MBP2018+mojave:
The good news is that I have the resource panel now which I don’t have when building against qt5.9. Still the render view is funky here.
Low resolution mode is not helping here.

@dcthomp Do you happen to have the environment variable `DASHBOARD_TEST_FROM_CTEST` set in your terminal? That tells the widget to run in low-resolution mode.
FYI I run ParaView from Terminal.app all the time without seeing the quarter-size rendering you are seeing.

Yup, that was it! It also does other Qt things that I enjoyed (like not popping prompts or adding menu animations), but I would rather have a full-size render window.
