Qt Designer on high DPI screens

  • How do you guys design in Qt Designer on hi dpi screens? Qt Designer is dpi-aware application so everything is scaled already in design-mode. But once you launch it, the app appears 4-times as big. Scaled twice, or even thrice. How to avoid it?

  • Qt Creator seem having same problem. No matter what screen you are using to use designer, Qt::AA_EnableHighDpiScaling assumes that the form was designed at 72 DPI, though it's ancient. Standard DPI is 96 DPI. How can i let Qt::AA_EnableHighDpiScaling know which is base DPI it should rely on to scale?

    Hi and welcome to devnet,

    I'd recommend posting this question to the Qt Creator mailing list. You'll find there Qt Creator's developers/maintainers. This forum is more user oriented.
