Dear developers, I am experimenting with a new event type that will contain additional information compared to MouseEvent. In particular since the event is generated for 3D content, there will be 3D hitpoint position and normal. However I am little confused with event generation system and picking. Please let me explain in more detail.
I have a number of new element types that I have introduced into WebKit. The only element that has a renderer is 3D scene root element (XML3DXml3dElement). Renderer overrides RenderBox::nodeAtPoint, which returns the node that corresponds to the actual element in the DOM that is under the mouse. Now I need to create XML3DMouseEvent instead of MouseEvent somewhere. I have tried to figure out how the mouse events are generated by stepping through the code. I have learned that for mouse move events WebKit::WebKitImpl::mouseMove starts picking process (that reaches XML3DRenderer::nodeAtPoint at some point), then generates and dispatches the event in Node::dispatchMouseEvent. Should I override Node::dispatchMouseEvent? How can I pass the extra information that I need to put into event from RenderBox::nodeAtPoint to Node::displayMouseEvent? Do I need to extend PlatformMouseEvent class? Thank you for your answers.
