my understanding is that in the old days, the window ref (int) in the plugin SDK used to be just a type case of carbon windowRef (a C pointer).
in 64-bit you can't just cast an address (64-bit) to int, the value would overflow. so the references are now mapped internally to real pointers (around v14). MDI is a different issue. because v16.0 beta or v16R and v17 are Altura-free, the old get-HWND(0) method to get its reference does not work. so a new entry point 719 was added in v16. https://github.com/miyako/4d-plugin-window-control https://github.com/miyako/4d-plugin-mdi see also https://github.com/miyako/4d-plugin-activate > 2019/02/01 7:40、Peter Hay via 4D_Tech <4d_tech@lists.4d.com>のメール: > So, does anyone know how to get the 4D window ref of the main 4D > application MDI window for 64 bit 4D apps? ********************************************************************** 4D Internet Users Group (4D iNUG) Archive: http://lists.4d.com/archives.html Options: https://lists.4d.com/mailman/options/4d_tech Unsub: mailto:4d_tech-unsubscr...@lists.4d.com **********************************************************************
