I see a new Grid class in v5.1.2. But when I run the JuceDemo, the grid demo doesn’t show up.
Hunting around a bit, the Grid demo is in a #if JUCE_HAS_CONSTEXPR, which evaluates to false for me. I’m using g++ 6.3.0 in Ubuntu 17.04. From what I can tell, g++ does have support for constexpr, not sure why that is set to false.
What I am I missing to see the Grid demo? I’m especially curious to see the difference between Flex and Grid. The doxygen help is light on details with both of these relatively new classes.
