DotNetBrowser 3.5.1

Extend mouse event properties

The KeyModifiers and MouseButton properties have been added to the MouseExited, MouseEntered, and MouseMoved events in DotNetBrowser to provide additional information about the state of the keyboard modifiers and mouse buttons during these events.

browser.Mouse.Entered.Handler = new Handler<IMouseEnteredEventArgs, InputEventResponse>(p =>
{
    if (p.Button == MouseButton.Left && p.KeyModifiers.ControlDown)
    {
        return InputEventResponse.Suppress;
    }

    return InputEventResponse.Proceed;
});

.Net JavaScript objects string size limit

Implemented the Chromium design limitation on the maximum string size for JavaScript objects (e.g., IJsObject) when sent from .NET to JavaScript. The limit is 2^28 − 16 bytes for 32-bit and 2^29 − 24 bytes for 64-bit.

To prevent the Chromium process from crashing when this limit is exceeded, an ArgumentException is now thrown.
