Hi,
The function here in the doc doesn’t exists in code. I grepped the whole JUCE library to be sure. Thought I’d report, just in case, unless I’m missing something 
https://docs.juce.com/master/classLookAndFeel.html#ad6764bcf3fbb1983287379f2ed034337
Cheers,

@sigmate, I see it in juce_gui_basics/lookandfeel/juce_LookAndFeel.cpp line 137 as of JUCE v5.3.1
/me bangs his head on the wall
That’s a quite recent addition, so Sorry for the noise.
Don’t forget to call it like this and not directly:
LookAndFeel::getDefaultLookAndFeel().setDefaultSansSerifTypefaceName(“Tahoma”);
Aw yes, I learned this just before you posted 
Thanks a lot!
Top!
How come I can’t call this in the constructor of my custom LookAndFeel class?
The really weird thing is that most windows and text is ok & displays the new font correctly, except for 1 random tab in my preferences window, where “F” becomes “n” and “+” becomes “M” & “9” becomes “a”, among other issues. Other tabs are A-OK. Also this issue only occurs on Windows, but seems persistent across different machines.
But thanks for the fix, looks like it got set straight
