[FIXED] How do the cross-platform windows frameworks like Qt work? Are they wrappers around native API?

Issue

Are QT/WxWidgets wrappers around respective native APIs' on linux, windows and Mac?

How are cross-platform windows framework built? How is cross-compiling done?

Thanks

Solution

Yes.

Sometimes they use lower level APIs to generate their own implementation of higher level APIs; like one that uses OpenGL to implement non-OS widget library. At other times they could adapt/reskin/modify OS widgets.

They are usually not cross-compiled. They just build and provide a similar API on multiple platforms, allowimg "client" code to compile with fewer changes on multiple platforms.
