>"Coincidentally, Win32 is also the only stable API on Windows"
And this is what I use for my Windows apps. In the end I have self contained binaries that can run on anything starting from Vista and up to the most up to date OS.
Honest question, do you get HiDPI support if you write a raw win32 app nowadays? I haven’t developed for windows in over a decade so I’ve been out of the loop, but I also used to think of win32 being the only “true” API for windows apps, but it’s been so long that I’m not sure if that opinion has gotten stale.
As a sometimes windows user, I occasionally see apps that render absolutely tiny when the resolution is scaled to 200% on my 4k monitor, and I often wonder to myself whether those are raw win32 apps that are getting left behind and showing their age, or if something else is going on.
IIRC yes but you have to opt into it with a manifest (or an API call).
I use Delphi for my "official" windows desktop applications. They have GUI library that wraps Win32. Seem to handles HiDPI just fine.
I do use raw Win32 but not for GUI stuff.
GDI32 has always had support for configurable screen DPI. You used to be able to customize it in Win95 but they hid the setting because too many poorly developed applications were written with inflexible pixel based dimensioning. If you lay everything out in twips it will scale without any special effort.
