[PATCH v3 1/3] user32/tests: Test restore window messages. - wine-devel

4 Jun 2019

Mostly to show that there is a WM_ACTIVATE message
before WM_SYSCOMMAND SC_RESTORE and after WM_WINDOWPOSCHANGED
This test won't work on non-Windows because the emulated key inputs
doesn't reach the host, unless we required user interaction, e.g.,
clicking on the taskbar icon or Alt+Tab manually.

v2: SetActiveWindow only when restoring from iconic state and window is visible.
v3: Add a test to verify message sequence. Previous comments say the fix
    is for Mirror's Edge, but in fact it is for Project CARS. I remember incorrectly.
