Hi All,
*Please read my problem statement:*
*JS Code:*
var mouse = MouseAndTouch(document, downHandler, upHandler, moveHandler);
function MouseAndTouch(dom, down, up, move) {
-----
--------
var container = dom;
-----
*container.addEventListener("mousedown", mouseDownHandler, true);*
}
Where passed argument in JS API MouseAndTouch () document is of type
Document and downHandler, upHandler, moveHandler are JS callback.
function mouseDownHandler(e) { // JS Callback
container.removeEventListener("mousedown", mouseDownHandler, true);
container.addEventListener("mouseup", mouseUpHandler, true);
---------------------------------
}
As per given above code snippet, I want to replace this JS code by C++ code
and want to handle event mechanism inside separated module written in C++
module. As I debug and I saw that api *container.addEventListener("mousedown",
mouseDownHandler, true); is invoking Node:: addEventListener(). When any
eventing is done on HTML element.*
*Now I have seen that in JS second argument for addEventListener is
callback (event handler) and corresponding JS handler is getting executed
when matched type of event is caught. But when I saw Web Core code to pass
C++ handler(Replaced code of JS handler to in CPP) and trying to pass
app *mouseDownHandler()(Converted
in CPP) in node->*addEventListener() in CPP it is giving type mismatch.
This is giving error because signature of API is *
virtual bool addEventListener(const AtomicString& eventType, *
PassRefPtr<EventListener>*, bool useCapture);
Please let me know how can we handle event mechanism using
node->addEventListener in CPP(webcore internally).
Bottom of whole discussion is that I don’t want to handle event mechanism
via JS if any event happened on HTML element.
Thanks & Regards,
MK
