From 9d6ac3deff1c71fe140d51dff117cddc1672f560 Mon Sep 17 00:00:00 2001 From: Sam Lantinga Date: Tue, 5 Jun 2018 12:46:09 -0700 Subject: [PATCH] Fix creating a minimized window in SDL to not cause focus to be stolen (because ShowWindow( hwnd, SW_MINIMIZE ) would be called after creation, thus changing focus to the prior window based on some per-app list in windows, rather than the window being created with WS_MINIMIZED to start with). This means we have to consider SDL_WINDOW_MINIMIZED a window creation flag, but on non-windows platforms we just remove it and let the normal FinishWindowCreation re-apply and do the minimize as I have no idea what is right on them or if anything should change.
