Qt4/KDE4 software under 10.14

[Michael Dickens]

The Qt4-provided native apps seem to work correctly with no display issues.

I have "my usual" ports that use Qt4 mostly working on 10.14: mostly GNU Radio and related. These apps are using PyQt4 as the interface to Qt4. At least in my testing, PyQt4 has some display glitches that make it challenging to use: the Qt4-based windows flash a lot, and at random times. Doesn't matter dark or light mode. Note that MacPorts' PyQt4 is not at the latest version (due to major compatibility issues with it and current ports) -- so there might be some fixes already in place for this way of using Qt4.

Beyond the flashing, the Qt4- and PyQt4-based GUI widgets otherwise execute as expected: widgets, popup menus, live graphs, toggle buttons.

I can't test everything that Qt4 provides, of course. And I haven't tested any other Qt4-based native apps.

Hope this is useful! - MLD
