Dark mode APIs RRS feed

  • Question

  • Hi,

    Does Microsoft plan to document and support the dark mode theming APIs recently added to Windows 10?

    i.e.

    DwmSetWindowAttribute with a DWMWINDOWATTRIBUTE of 0x13.

    uxtheme.dll's AllowDarkModeForApp (ordinal 135) and AllowDarkModeForWindow (ordinal 133).

    The ribbon properties UI_PKEY_DarkModeRibbon and UI_PKEY_ApplicationButtonColor.

  • Hi splidge,

    I'm not sure what's the plan of Microsoft. But, You could use it as the following:

    1.

    SetWindowTheme(hwnd, L"DarkMode_Explorer", NULL);

    2.

    using TYPE_AllowDarkModeForWindow = bool (WINAPI *)(HWND a_HWND, bool a_Allow);

    static const TYPE_AllowDarkModeForWindow AllowDarkModeForWindow = (TYPE_AllowDarkModeForWindow)GetProcAddress(hUxtheme, MAKEINTRESOURCEA(133));

    AllowDarkModeForWindow(a_HWND, true);

    SetWindowTheme(hwnd, L"Explorer", NULL);


    Best Regards,

  • I've been banging my head on this all day, and SetWindowTheme only seems to work on a very select few controls, like buttons, split buttons, and scrollbars.

  • The dark theme graphics is only implemented/designed for the few controls that are needed by Explorer windows and Open/Save dialog. Besides that, you are out of luck and need to draw everything yourself.
