vkconfig3: Text hard to read

[richard-lunarg]

The bright blue is very hard to read when the Mac is in dark mode.

A difficulty is that dark mode support is pretty new in Qt.

Here is a code example that could be useful in the future:

#include <QGuiApplication>
#include <QPalette>
#include <QStyleHints>

inline bool isDarkMode() {
#if QT_VERSION >= QT_VERSION_CHECK(6, 5, 0)
  const auto scheme = QGuiApplication::styleHints()->colorScheme();
  return scheme == Qt::ColorScheme::Dark;
#else
  const QPalette defaultPalette;
  const auto text = defaultPalette.color(QPalette::WindowText);
  const auto window = defaultPalette.color(QPalette::Window);
  return text.lightness() > window.lightness();
#endif // QT_VERSION
}

Have you considered bumping up to Qt6 for version 3?

Have you considered bumping up to Qt6 for version 3?

Would this be reasonnable? Specifically regarding the Ubuntu linux distro we support?

[richard-lunarg]

Yes, we are up to Qt 6.6 now, and it is available on Linux as well. Ubuntu, Raspbian, etc.

I resolved this issue by copying dynamically to the text color to the html tag:

It turns out that themes would have not resolved this. Not sure how this is typically handled...

This is resolved here: #2205 but it's a pretty tedious solution. :/
