Finish LINQPad Dark Theme?

rorourke

Are there any plans to finish/implement the dark theming for the regular elements of the UI? Menus, pop-up dialogs, etc. Or even just following the current Windows theme.

While I don't live in Query Properties or the NuGet Manager, they come up often enough to be highly jarring relative to the rest of the UI.

The main menu, all context menus and the main toolbar will be properly dark-theme rendered in the first release of LINQPad 8 (there should be a preview out next week). The icons in the TreeViews (and nearly everywhere else) will also be drawn with a vector-based renderer that's dark-theme aware. Some of this required a WPF rewrite, which is why it took some time. There are plans to improve other areas in the following months. What would you rank as the most important elements?

Glad to know the work proceeds. Thanks Joe.

In terms of priority:

Query Properties
NuGet Manager

Those are the two dialogs I encounter the most.

Would it be much of an issue if Linqpad added support for "immersive dark mode" (native themed titlebar) ?

Attached is a sample how it would look today.

void Main()
{
    IntPtr hWnd = LINQPad.Util.HostWindowHandle;
    NativeInterop.Dwmapi.UseImmersiveDarkMode(hWnd, true);
}

internal static class NativeInterop
{
    public class Dwmapi
    {
        [DllImport("dwmapi.dll")]
        private static extern int DwmSetWindowAttribute(IntPtr hwnd, int attr, ref int attrValue, int attrSize);

        private const int DWMWA_USE_IMMERSIVE_DARK_MODE_BEFORE_20H1 = 19;
        private const int DWMWA_USE_IMMERSIVE_DARK_MODE = 20;

        public static bool UseImmersiveDarkMode(IntPtr handle, bool enabled)
        {
            if (IsWindows10OrGreater(17763))
            {
                int attribute = DWMWA_USE_IMMERSIVE_DARK_MODE_BEFORE_20H1;
                if (IsWindows10OrGreater(18985))
                {
                    attribute = DWMWA_USE_IMMERSIVE_DARK_MODE;
                }

                int useImmersiveDarkMode = enabled ? 1 : 0;
                return DwmSetWindowAttribute(handle, attribute, ref useImmersiveDarkMode, sizeof(int)) == 0;
            }

            return false;
        }

        public static bool IsWindows10OrGreater(int build = -1)
        {
            return Environment.OSVersion.Version.Major >= 10 && Environment.OSVersion.Version.Build >= build;
        }
    }
}

Thanks - I did not know about this API. Will add this to the next build.
