![]() Hi, just tested with C++, I'm on Monterey 12.4 Xcode 13.4.1 and Qt 6.3.1. Thank you for any advice! I appreciate your help. How does QFontDatabase determine that list? Perhaps QFontDatabase is reading a system-wide list or configuration of some kind - what might that be? How can I know, from outside of a Qt application, what is the list of fonts which QFontDatabase knows about? SECOND EDIT: It appears that, within a Qt application, QFontDatabase supplies the list of available fonts. That makes me wonder how I can determine the list of acceptable font names any info about that would be terrific. ![]() If I change the font to "Arial,9", the warning goes away. So that's where "Sans" mentioned in the warning message is coming from. ![]() I am not sure whether the responsibility for handling this font configuration question rests on Qt or on Gnuplot in any event, if I can find out what Gnuplot needs to tell Qt, I can go to the Gnuplot developers and ask them about it.ĮDIT: I see now that Gnuplot is confiuring its default Qt terminal with font "Sans,9". How can I configure Qt, or set an environment variable, or use a runtime option, or otherwise inform Qt as to the presence or absence of some fonts? What should I tell it? Replace uses of missing font family "Sans" with one that exists to avoid this cost. Qt.qpa.fonts: Populating font family aliases took 175 ms. ![]() When I try any plot with Gnuplot, I get a warning about "missing font family", e.g.: gnuplot> plot sin(x) I am working with Gnuplot 5.4 and I see that Qt 5.15.0 is installed although I am not sure if Gnuplot is making use of that or if it's statically linked. Hi, I'm working with Qt on macOS Cataline 10.15.6. ![]()
