LowLevelMouseHook (double-click & timing)

[w4po]

Hello,
I needed a fast way to detect a mouse double-click, I used the DoubleClick event but I found it slow for some reason,

After a quick look, I figured out why, it never catches the WM_LBUTTONDBLCLK message (I've implemented my mouse low-level hook and the WM_LBUTTONDBLCLK message isn't fired at all).

So in the LowLevelMouseHook class the isDoubleClick never true,
and the DoubleClick event is fired on the mouseUp portion:

if (mouseUp)
{
    OnUp(args);
    PreviousDownTimeDictionary.TryGetValue(key, out var previousDateTime);
    if (DateTime.Now.Subtract(previousDateTime) < DoubleClickSpeed)
    {
        OnDoubleClick(args);
    }
}

Which is not that fast because at the second click the user might be slow to release it.

So I think it would be better to check for double-click on the mouseDown portion (Which isn't always what everyone needs)
So an option to choose would be much better.

The other thing that I noticed is the current implementation checks for timing using DateTime.Now, I think it would be better to use Environment.TickCount

Here is how I solved the issue:

    private static void MouseHookOnDown(object? _, MouseEventArgs e)
    {
        if (e.CurrentKey != Key.MouseLeft) return;

        var now = Environment.TickCount;
        if (now - _lastClickTime < 400)
        {
            // Double-click detected
        }
        _lastClickTime = now;
    }

Thank you for your awesome work <3
